Do these ultra high energy storage flywheels have gyroscopic forces that resist the rotation of the turning of the earth? As the hours go by, a flywheel mounted vertically will change orientation due to the earth's rotation to a non-trivial extent. Gyroscopic forces would certainly exert pressure on the axis of rotation. Could this contribute to flywheel losses? I imagine that a flywheel storing a huge amount of energy would have to be pointed at true north and tilted to be parallel to the axis of the earth to cancel out this problem, but none of the flywheels you showed in your video seem to be doing that.
It is so foolish for the global warming and climate change alarmists to think doing away with fossil fuels is a good idea. In fact, the accumulation of fossil fuels, biofuels and sequester of CO2 in the ground for a long period of time will eventually lead to a repeat of the largest mass extinction of life on earth like that happened 250 million years ago when massive volcanic eruptions caused huge amount of CO2 and natural gas trapped underground to be released into the atmosphere. We know the killer lake Nyos killed a large number of people many years ago when the CO2 accumulated at the bottom of the lake released all at once during an earthquake. Since then some smart scientists have been keeping the lake safe by releasing the CO2 from the bottom of the lake into the atmosphere gradually with pipes and pumps. Suppression of CO2 release into the atmosphere by banning fossil fuels and by sequestering CO2 in the ground is as stupid as suppressing the dissipation of CO2 from the killer lake Nyos into the atmosphere by banning the degassing with pipes and pumps.
I do not ven know if this is a current thing or even possible but... Magnetic bearings for the flywheels? Can't lose energy to friction if there is none yeah? Or even the much harder possibility of using quantum locking (but how would we keep it that cold?)
@@Berkana Eddy currents. You can use windings to reduce that but IIRC that was to redirect the energy not prevent losses. But I would still love to see comparative testing.
I have personally machined hundreds of large rotors and housings for a company called 'Active Power'. It's my understanding that flywheels are used in uninterruptable power situations to provide an instantaneous response to a power disruption, say in a hospital for instance. They are only used for very short times, until standby diesel generators can take over.
About 40 years ago our computer branch ( in very large government department) pulled its electricity supply from a electric generator powered by an electric motor. Sandwiched in between this motor/generator set was a 1000 kg steel disc flywheel. This revolved at 1500 rpm. The purpose of this system was to isolate the computer branch from very short term power loss and electricity spikes.
That is right, normally it is not wisely to store large amounts of energy in an inertia wheel with large angular momentum, because the failure mode associated with bearing failure has catastrophic effects, well documented 70 years ago, when MFO build and operated so called gyro buses having a vertical axis flywheel, which had to be recharged on every stop. They were eventually delivered to Adìs abeba to fulfill Haile Selassie personal oder . During testing one had a bearing failure, broke out of the enclosure up the test pit and destroyed a considerable number of machine tools on the factory floor, needless to say that the redesign lead to considerable derating of the system, essentially eliminating other customers.
Imagine a carbon nanotube wheel in your car that stores 400 miles of driving energy. It will level buildings when it frees itself. Not to mention the handling of a car with a giant gyroscope inside. You can only drive level on flat surfaces.
@@mennovanlavieren3885 Actually the gyrobuses had double gimbaled flywheel suspension, exercising no torque on the vehicle on startup the gimbals had small orthogonal torquers to keep the axis upright
Two other things. The faster you spin a large mass, the more dangerous it is if something goes wrong. Also, the faster you spin your flywheel, the faster you lose kinetic energy by heating up your lubricant. Also, shouldn't lubricants be worse at lubricating at higher rotational velocity? Fluid resistance is roughly proportional to speed if I remember right.
Good point about the lubricants. It also applies to eddy currents in magnetic bearings-so you'd still be right even if they were using those and not ball bearings or roller bearings.
Kodiak Alaska produces over 99% of its electricity from renewable sources (wind and hydro). They originally used Lithium ION battery banks as their battery storage solution. However, while lithium ION batteries are great for consistent stable power flow, when there are spikes in the grid it puts a lot of strain on those batteries, aging them prematurely. Kodiak is a big fishing town, and the spikes were expected to come from a new electric crane they would use for ship loading/unloading. To solve this issue, they added flywheel storage to the mix. The Lithium ION batteries provided a stable energy output, and the flywheels kicked in to handle spikes in power. To my knowledge, they were one of the first, if not the first public power grid to use both these solutions in tandem. It is still in operation to this day.
The company ESS makes Iron Redux flow batteries and it's probably a better solution but it would require good insulation and a little heat applied to the containers for the batteries.
Kodiak port wanted to install a new 2-MW crane, potentially causing destabilizing power fluctuations leading to undesirable cycle of the batteries. This is why they got the ABB fly wheel, and an electric crane, displacing thousands of gallons of diesel and millions of dollars of diesel costs. This also reduced the transport of thousands of gallons of diesel in extreme weather conditions. And, lowered the kWh cost to residents.
#1: No heat? I think somebody's pulling your leg. The resistance may seem futile, but it is still there. #2: These are likely to be most useful for phase maintenance, keeping fluctuations as various sources and sinks go on- and off-line to a minimum.
Yes. How can something lose 3% of its rotational energy per hour and not generate heat? Where else can that energy go? It doesn't make chemicals, its mass isn't increasing, it's not raising itself into the air, etc. So... it must go into thermal. If it is slowing, that energy must go into heating bearings.
Potter's wheels, spinning wheels, and the so-called "great wheel" lathes we're all examples of flywheels, also sewing machines used to use treadle operated flywheels as well. Basically, before the steam era flywheels were powering a lot of industry
They weren't really powering anything though. They were just acting to smooth out irregular energy flow over a period of seconds. More like a modern capacitor than a battery.
@@vylbird8014 And it was fun to spin up the pedal sewing machines. That didn’t last long. It was fun as a kid, but I learned fun could be curtailed by an angry mother.
I’ve been hearing about carbon nano tubes for at least 20 years! They are always right around the corner to produce at scale. Sort of how unclear has been coming for 20 years.
A few commercial products have been made using carbonara nanotubes, mostly sports equipment. We have only known that carbon nanotubes existed at all for about 30 years, so it isn't all that surprising that we have a while before technology developed with them isn't mature yet.
If they can make them more robust, the best, as you already stated, is using supercaps for storage. Gravity batteries seem to be a better option for now than using flywheels. Just an opinion. Again, until they can figure out a better supercap method, it's gravity batteries to the rescue. Have to have a sufficient way of using gravity of course meaning the space is astronomically much bigger than a flywheel, that is for sure, but at least you don't lose much energy (if at all) from idling. :)
There may be no losses when a gravity storage system is inactive. But it's not as efficient during its active states. The best "gravity storage" is water in the form of pumped hydro storage, which makes up more than 90% of the total storage worldwide and is a mature technology over 80 years old. There are a lot of inactive open pit mines which could be used for pumped hydro storage.
It would be pretty awesome to see small flywheels applied to say a ride on lawn mower, tools that could potentially be "charged" up for the job, and then let run to zero before needed to be used again
My Grandfather built a telephone exchange power system back in the 1930's and they used a 16T flywheel to rotate using an electric motor with a diesel motor as a backup. They had a catastrophic bearing failure and caused the 16T wheel to take off out of the retaining pit, through the wall of the power building and down the street of the town. it ended up in the council hall with no-one hurt, just a lot of damage. needless to say the next ones had a far deeper Pit under them.
It's not the only case of bearing failure, In the Textile producing mills of Lancashire and Yorkshire a number of recorded bearing and shaft failures occurred and with Rope Race's or flywheels weighing up to 90 tons the destruction caused was horrendous.
Replacing all Fossil Fuels with Renewable electricity is a great goal, but it’s actually not the first step. The first step will be to get to a “net zero” situation. According to the book Drawdown, we can actually achieve that while still having about 25-30% of our electricity generation come from fossil fuels. This means that the big push for better battery storage doesn’t really need to yield results until around 2035 (which will give us enough time to deploy it by 2050). I bring this up, not because I disagree with this video, but because I’ve noticed that many people seem to use the excuse of “electricity storage isn’t solved yet” in order to delay deployment of our current renewable energy tech. The truth is that our current solar and wind tech is good enough so we need to push hard to deploy it as quickly as possible!
@@RandomGuy-nm6bm there’s not actually any singular solution. The team zeros in on a top 100 solutions which all contribute in various ways. You can find more info on the by searching for “drawdown solutions”. But here’s the gist of the general categories: - electricity: rapidly deploy current tech with emphasis on solar and wind. - food: cut our levels of meat consumption down dramatically and convert to cooking methods which use electricity - Agriculture: restore soil health by no longer tilling. Use methods like composting, tree intercropping, biochar, etc in order to replace current fertilizer usage - Buildings: aggressively retrofit current buildings with electric appliances, insulation, and smart tech to prioritize energy use. - Land Use: build nature back up in the areas where we’ve destroyed it - transport: switch to electric powered where possible. Drastically reduce the amount of private cars by pursuing mass transit and bicycle transit where applicable - Materials: create more closed loop production processes for key materials. There weren’t any machine carbon capture points which I can remember but there was a lot of carbon capture which would be done by changing our agriculture methods and rebuilding various areas in nature. Hopefully this answered your question.
Good old SAAB 92 (with a drag coefficient of 0.30) from 1949 had a flywheel. In order to overcome the problems of oil starvation during overrun (engine braking) for the two-stroke engine, a freewheel device was fitted. Different application however.
Pretty sure that a standby loss of 3% per hour can be greatly improved. Magnetic bearings in a vacuum are frictionless in mechanical terms. There are ohmic losses in the magnetic bearings, given the way magnetic bearings are commonly implemented. I.e., with electromagnets driven by variable current controlled by feedback from position sensors. But that's a stupid design. There are better options. Permanent magnets positioned to hold the load at its metastable neutral point, stabilized by low drag dynamic levitation with zero force / zero drag at the neutral point. Great for maglev trains also. You could do an interesting video on that.
I love that you explained the physics behind flywheels, but I think you got a little derailed by the gravimetric energy density numbers. The mass of the wheel itself is unlikely to make much difference in the viability of our grid-stabilizing flywheel energy storage system.
Another possible material is single crystal sapphire whiskers (aluminum oxide)... Currently tested to 10-11 Gpascals with a theroretical for Aluminum oxide of 30 Gpascals... equivalent to te 30 GPascals of carbon nanotubes. they do have the same issue of length as do carbon nanotubes, however they do not have the issue of being burnable.. as they are already oxidized.
Thermosyphoning liquid metals such as mercury through a coil to produce electricity was discovered many years ago. This only requires low grade heat to operate, and there is a gigantic amount of low-grade heat currently underutilized. Imagine the heat from road surfaces for example, or roof spaces, hot sides of structures and so on. The metal circulates around and around and there are no other moving parts and it is said to be 55% more efficient than an alternator. I enjoy your explorations so much, thanks.
When you have the NanoTubes you can make a battery using aluminum that is three times as dense as current batteries under development. This research is ongoing in Australia.
What comes to mind about flywheel storage is that it needs to be coupled with something that can store that energy for a long period of time like capacitors for example.
It would only be cool if they made them for Farmers. Cheap, and available packages. My plan is to not spend money on a fly wheel but to use instead what the power companies us now... water storage. The pumping of water to a higher area during the day from solar or intermittent wind systems during the day mean that water can be stored and then released to power a generator later at night. The system can be an enclosed system (same water used back and forth) So this fly wheel idea (something I thought about 40 years ago) whilst cool may just be a side step in the wrong direction. I cant see how this would have space applications either..
Even as a kid, I thought flywheel energy storage was the solution for line conditioning (at a mass scale). Turns out, I wasn't too far off. But what I learned from this video: flywheels lose energy very quickly. I had no idea. I thought it maintained it's inertia in a vacuum very well and took months to lose all it's energy. I was very wrong. That's disappointing.
It's a lot more than 5%. The biggest issue is that cheap power has made people complacent. A lot of things need to change, and you will still need the base-load capacity online to provide the copper base to dissipate harmonics. A mix of renewables and nuclear are the way of the future. I was in the naval nuclear program and operated a reactor on a submarine, and saw what was capable with good operators and stable design
Military use is far different from Commercial, where the pressure for profits NOW lead to companies scaling back needed maintenance. That was the cause of the Texas Grid failure in 2021, the BP Deepwater Horizon blowout, and hundreds of other industrial disasters. Second, the problem of long-term storage of nuclear waste is dimply too long-term for the human race. Human lifespan is trivial compared to radioactive waste. We have no experience solving problems with at that time scale. No government or institution has ever lasted long enough to manage this problem. And Third, it's unnecessary. Solar and Wind can generate more than enough power. Stop thinking about huge localized generation and start thinking about localized generation. The benefits of local power generation are tremendous. Energy Security is just one. For less than the cost of the 2nd Gulf War we could have put solar PV panels atop every house in the USA.
@@guygordon2780 you are wrong.. We have reactors now that use far more radioactive energy out of the fuel and the half life of the spent rods is in hundreds of years vs thousands.
@@guygordon2780 solar and wind are more dangerous to the ecosystem and wildlife than nuclear and they aren't nearly as reliable. Nuclear is the cleanest power known to man also they have found ways to deal with the little waste they produce witch is drilling a hole deep under the power planet and putting the wast into sealed cassel
There's a lot going for for flywheels in grid storage but I'm really worried about gyroscopic effects in vehicle applications, it could send someone off the road under some conditions.
I remember flywheels being used on steel rolling mills. e.g. when the mill rolls were at optimal speed from a DC motor, the steel ingot was fed into the rolls. This was a sudden energy requirements which the fly wheel provided. Today, bigger motors and better drive controllers can provide this energy surge. So the flywheel concept is pretty old and has specific uses. I saw one huge flywheel in BSC (British Steel Corporation) which was made in Germany before the war. The Germans (maybe Siemens) made 2 and they spent the war years stored in a field. I heard of a turbine generator where the breaker tripped but the steam didn't so it came away from it's holding plate and took off down the turbine hall, through the wall and kept going so spinning objects can be pretty scary. I used to work on a test rig at Rolls Royce Helicopters where rotor bearings were cycled up to 50,000+ rpm in a vacuum chamber. GEC turbines balanced their turbines in a huge vacuum chamber and they took up to 4 hours to get up to speed and 4 hours to slow down again. Ok, irrelevant but the basic technology has been around for yonks and it's great to see it coming back again as new technology is developed. As I see it, it must be applied to the right application. The f1 example sounds perfect.
It is relevant to others that it is a powerful energy storage illustration. I remember a small documentary show, where they built a small 1 m diameter flywheel and spun it up to speed, they were suddenly very scared. Hahaha Hahaha 😆 They backed down.
The flywheels shown are sitting parallel to the earth’s surface, but the earth’s orientation changes 360° every day. How do these flywheels cope with the resultant precession effects.
I also wonder what type of bearings are used? Air layer or magnetic levitation or just standard roller bearings? Also the torque from procession might be able to be converted to power too?
Torus, a company out of Utah, has a home model. The entire system, including solar panels, inverters, etc costs around 50K and is supposed to last for 25 to 30 years.
I did see this concept not to long ago here on TH-cam (go figure) but they were talking about using a super cheap material for the flywheel mass....concrete. a cylinder buried in the ground in a vacuum sleeve, I believe using magnetic bearings.
Oh, yes, flywheel energy storage is breakthrough. Wiki: "In the 1950s, flywheel-powered buses, known as gyrobuses, were used in Yverdon (Switzerland) and Ghent (Belgium) and there is ongoing research to make flywheel systems that are smaller, lighter, cheaper and have a greater capacity."
Is the electrical energy recovered from the flywheel system really 90% of the electrical energy used to spin it up? I thought the complication of dealing with variable flywheel speeds while providing stable voltage levels would waste more energy.
So just to keep your flywheel spinning you're wasting 20% of the energy. Sounds like a solution for a very specific problem. Where power is in excess but it might cut out or you might require a spike in power supply.
When a flywheel slows down, I imagine most of the energy is dissipated via friction? Would that not cause heat production, sound and/or material deformation? Assuming the latter is designed around, and the energy losses to sound are negligible, that leaves heat.
Great video Ricky, very interesting! I live in Canada and I split a lot of firewood every year. I recomended to my community that we buy a 40 ton kinetic wood splitter this year and it is amazing! It has 2x50lb flywheels and the splitting time is 2 seconds per split vs 12 seconds per split for the standard hydraulic splitter. I split tens of thousands of pieces of wood every year so it makes a massive difference! Then between splits the engine is idling on medium low to spin up the flywheels again and so I can split 3x as much wood per tank of gas compared to our standard hydraulic machine. It does cost a little more to buy the machine in the first place but it is well worth it and only a flywheel can deliver that high impact force needed to split knotty hardwoods.
Interesting, I'm planning to build a kinetic splitter at the moment after watching a TH-cam video of a guy who made his own using a Lister D stationary engine to power it. Considering that his engine only produces one and a half horse power the results are truly impressive.
personally I think in a near future world where we run primarily off of renewable power and use more traditional methods as a backup even today's flywheels fit the bill for that very short term top up while we get the old generators back online
Williams F1 developed but never used in competition a flywheel energy storage system for their F1 cars. They (and all other teams) ran and still run lithium batteries for their energy recovery systems.
I'm sure the flywheel battery is excellent system. By the way why don't you use oil bearing for vertical axis? It has very good lubrication which is applied for turbo molecular pump. Next question: Maybe you use a DC motor. Voltage of the motor (generator) goes up and down by charging energy or discharging. What is the range? If you use a system of changing frequency , how do you control the line voltage?
With flywheels, and other solutions, the fact that there is an existing market, bodes well for the future. Its easy to imaging incremental improvements expanding a market.
Great video! Side note, I didn't realize we had the ability to make 14cm C-nano tubes already. Last I heard they could only make 1 cm long ones. Space elevator possibilities fill my head again. Imagine using earth like a giant flywheel! We couldn't use enough of the energy to see it ever actually slow down. Lots to calculate there.
flywheels should be in every light post and every building core .. you need alot o fthem to charge fast and dynamically like surge suppression ... flywheels work as surge guard layer .. with batteries behind them ... flywheels should discharge into Solid state batteries if they wont be used ...
When something seems like a great idea, but doesn't exist, there is usually a very good reason why. In some cases, there is a practical or technical reason why it simply won't work. In other situations, that solution only applies to specific use cases, such as the large sand battery used in Finland to provide heat to a community boiler network. This is only applicable where such networks exist or could realistically be built out. I think the same thing applies to the use of large flywheels; they will never be very common because their use case is too specific.
Can't help think that gravity storage might be a better answer. Use excess power to propel a really heavy train up a gradient. When power is needed allow it to run back down and drive a generator as it does. Regenerative braking on a giant scale. When this train is at the top of the gradient it doesn't lose that stored kinetic energy.
With the huge amount of investment and research going into carbon nanotubes for this amazing tech, I think it could also have many other groundbreaking uses, like the long dreamed of space elevator. For lighter worlds like Mars or the Moon, it's already achievable, but to start the dream, we need to begin it here first. Amazing content as always :)
the problem with flywheels is they all lose their energy in a day. so flywheels can be used to stabilize solar/wind when is intermittent in spans less than half a day. so maybe a during the night wind and flywheel work together, but if it is a still windless weather and long night maybe the flywheel won't be enough. This is why I believe flywheels are better used for peak time get the excess let the lithium battery discharge a bit and then recharge it with the flywheel.
in grid banks, size shouldn't matter too much, so wouldn't the initial cost be better if they made them out of cheaper slower rpm materials, and just have more? I really want to know more about this
The one big problem with this is the fact that you have 2700 watt-hours per kilogram of fully charged flywheel just waiting to be turned inevitably into thermal energy in the event of an accident. It would be like setting off an underground bomb. Probably wouldn't be an issue if they were sited in remote areas but it would make building an array of them really hard.
What about a material like T1000 infused graphene? Could that be a better material to make a flywheel out of? It's tensile strength would (or should) go up by a factor of 10 (theoretically).
Energy density for flywheels is not particularly important. We have plenty of space for implementation. While flywheels may be low maintenance themselves, the support equipment, mainly the vacuum pumps, will require regular maintenance.
it sounds good with the icing on the cake would be having these flywheels running together with the sodium sulfur storage battery charging this battery as it stores its power where the spinning type charger can take a break you can drop the RPMs once the sodium sulfur battery is stored up to it's maximum capacity where it drops to a certain point then the gyro spinning unit can kick back in to bring it back up looks like it's kind of like the way a submersible pump pumps the water into a storage holding unit when it drops down a float kicks in that turns on the submersible pump see what I mean 🧐🧐🧐🧐🧐🧐🙏🏾🙏🏾💞
Great video as ever, just a small quiblle on the 3% per hour maths - a percentage loss is always a percetage of what you have at the time, so the "a little over a day" is out the window - you were adding them up, giving about 33.3 hours of storage. But in fact, a 100kWh flywheel, after 24 hours at 3% per hour, would be down to about 49.6kWh and losing less than 1.5kWh per hour. After that 33rd hour, it would still have 37.7kWh, losing just over 1 an hour. That's not exactly a massive quantity left, I'll admit, but if you need to be able to access your solar panel power in the evening and you have plenty spare capacity in your panels and flywheel, it's absolutely fine. If you're interested in how the numbers carry on... after 48 hours, it's 23.98kWh, losing less than 1 an hour. After 72, we still have 11.5, losing .36 an hour. 96 hours, down to 5.5, losing just over 0.17 an hour. It finally dips below 1kWh in the 154th hour - 6 days, 10 hours. From there, the losses start to look a lot like AA batteries' charges and I've no real interest in dragging the formula any farther down my spreadsheet ;-)
Amazing good video! Been thinking about this problem since about 1978. What i've come up with; and I'm not an engineer, is a; 20 -100 max RPM, cascading system that uses compressed air and flywheels. Using a variety of flywheel charging means incorporating several kinds of alternate energy conversion means and devices; you charge; a huge, large diameter flywheel to a point where power can optimally be taken off and used to do work. The function of the horizontal tensile strength of the material used to hold the flywheel, is minimized. It reduces that; power lost at idle, factor. Giant Tapered roller bearings in planetary gear configuration support the multi ton concrete and rebar flywheel. Use three or more in consecutive "planned use" configuration.
I wonder how well it would work if the fly wheel was attached to a windmill or something of the sort. It would never really go into standby mode that way to lose all that power, but could continue to spin while not in use.
@@KastorFlux I think he might mean using an array of wind generators to keep it topped off all the time, even when demand is low. That's already part of the grid storage designs and in essence the point of using a storage system.
@@Mavrik9000 I did mean this, but I am glad it was explained why it doesn’t work in a way I could understand and not to be an a$$hole. I learn this way.
The wheel sits inside a steel vacuum chamber. The bullet would probably have lost its destructive power before contact with the wheel. CNT is a very hard material, so nothing much will happen there. But a sudden inrush of air will result in some unpredictable outcome when it gets into contact with the wheel that spins at a high mach number. The air will heat up and might explode, destroying the bearings and letting loose the wheel.
Density doesn't really matter for grid purposes. Just cost and loss rate. Carbon nanotubes don't address loss rate, and their cost is astronomical. Grid flywheels are best with whatever the cheapest halfway strong material is. Iron works. You're not carrying it anywhere, it can be bulky, that doesn't affect it's utility. Density could be useful in a vehicle, but it has immense gyroscopic force, and moving vehicles around (against that gyroscopic force) tears up a flywheel, and greatly affects vehicle handling.
The maintenance process alone will make this solution infeasible and the losses in energy due to conversion to kinetic and back not worth the expenditure.
I'm still trying to understand why we would need storage capacity of ONLY 5 percent of the total renewable energy production capacity in order to replace fossil fuels. Intuitively, that number sounds WAY too low. Considering the intermittent nature of wind and solar, it seems that amount of stored energy would not power the grid for long in the absence of wind and sunshine. What am I missing?
How much power does it require to keep a flywheel spun up could it be paired with another storage technique to prevent that loss while not being used? Or is that 3-20% factoring that in? And how are they spun up is it mag lev vacume with magnetic propoltion?
The key is not to depend entirely on solar. The ideal home and municipal grid would have a diverse array of generation and storage options. Each have their advantages. Solar generates a good amount during the day, wind generates all day, tidal/hydro has massive torque potential as well as consistency, and fuel should really be our backup when all else fails not our mainstay generation. To that, chemical batteries are energy dense but high maintenance, flywheels are low maintenance but need a bit of energy to keep their stored energy, gravity batteries are great for long term in my opinion but should be underground for their potential destructive capability if they fail (same with flywheels IMO). I have high hopes for thorium-uranium nuclear and cold fusion but they also should be part of a diverse grid.
Carbon nanotubes aren't a material. They're a molecular structure. They don't belong on the same list with bulk materials, including all the inevitable crystal boundaries and imperfections. It's like comparing the measured strength of one bulk material to the "strength" implied by the activation energy required to burn another material. Basalt fiber also has unobtanium-level tensile strength, when you look at individual fibers instead of at structures fabricated out of them. Also, for stationary applications like utility energy storage, mass isn't particularly relevant. What matters is levelized cost.
I'm a recent viewer, so haven't seen mention of Liquid Metal batteries, on this fascinating Channel, so don't know if the topic has been covered. Antimony/Calcium/Salt, battery operating at 700C developed by MIT's, Dept of Materials Science and Engineering, Dr Sadoway and His Ambri Battery Company based in Marlborough, MA, USA. A variation on electrochemical refining of metals. A site in Nevada, will have a 500 MW battery installed. Problem with Kinetic batteries, they consist of moving parts.
They might have to use a giant fully gimballed carrier for these flywheels. Unless you place the flywheels flat exactly over the north or south poles. "Flywheel energy storage systems using mechanical bearings can lose 20% to 50% of their energy in two hours. Much of the friction responsible for this energy loss results from the flywheel changing orientation due to the rotation of the earth.."
The "Gaps between Primes" Mathematical Disproof Methodology applied to chains of axial-tangential resonances in sequence "explains" why horizontal-vertical lines of sight horizons due to relative-timing probability-frequency alignments, limits the stability of connected molecular chains, or the half-life duration of physical elements in general, because everything is composed of log-antilog Conformal Field Condensation, ie QM-TIME e-Pi-i sync-duration connectivity Completeness is a continuous Reciproction-recirculation Singularity repositioning-shaping function. Nothing can last forever except No-thing.
Just as sensational and new now as when i read about it in science magazines in the 80's. Newsflash: any spinning wheel will start to slow down once no more force is applied to it. (unless its floating in outer space)
to mee it sounds like you want a hybrid power station so that if in the UK everyone starts their kettle you have that flywheel in place to take the surge hit and charge it up again for the next peak of power demand. Have chemical, thermal batteries or like a bit Gravity battery "water?" for the general storage of energy
If flywheels were worth it, by now you would see them in the basement of many homes so you could charge them at night when electricity is cheaper, and then use the power during the day. But you don't. The free market has spoken.
Switching electric power supplies are efficient and operate as delivering energy during a timeperiod of then a timeperiod of no power delivered; I wonder if a flywheel can be charged and maintain its energy using electric motors and switching power supplies having a longer off period allowing a flywheel to deliver energy during the off periods
It was easy to guess that is something to do with "Carbon, Nano, Graphene". Same as ten years ago. No word to the extreme gyroscope effect in vehicles?
It May Be Possible In The Near Future That Compact Modular Reactors Could Safely And Efficiently Provide Sure Power To Small Cities Or Large Neighborhoods For Many Decades On Their Own Independent Grid.
I don't think flywheels will be practical for vehicles simply due to what would happen in a collision. I imagine an ultra-fast spinning flywheel getting into a major accident cause horrifying damage to its surroundings.
Carbon nanotubes are good in supercapacitors. Is anyone working on double dipping? Obviously, you probably want to charge/discharge with the rotor stationary.
The only issue with using a single flywheel in a modern motor vehicle is the gyroscopic effect. This would make the vehicle very unsafe. Perhaps get around this issue by using multiple flywheels spinning in different direction.
@@willjapheth23789 Hi Will, I accept that. The race car operates on a relatively flat track - no sharp vertical curves. If you check, the flywheel axis is set vertically so that it would not effect cornering. However if it were to undertake sharp vertical turns then the gyroscopic effects would appear. My comments relate to normal everyday use. On an off road 4x4 going over very rough ground conditions the gyro would have to be turned off . Any sudden changes in the vertical plane would cause the vehicle to change direction. This effect is easily demonstrated when a motor cycle turns a sharp corner and the rider leans the bike over into the curve. What holds the motor bike in this precarious position are the gyroscopic effects of the wheels trying to move in the opposite direction.
@@johnspathonis1078 yea hills and valleys matter the most. Doubt the 918 RSR never gets tilted. Also the bike effect is mostly due to the angular momentum of the whole bike not the wheels. Like 1 G turn should allow you to lean 45 degrees regardless of gryo effect. Racers can do more than 1 G turns.
@@willjapheth23789 Hi Will I don't know if your a mechanical engineer but I have designed vehicles to comply with national design rules (ADR's). In vehicle design they talk about friction utilisation factors (basically coefficient of friction.) A very good coeficient of friction is 0.6. To pull 1 G the coeficient of friction must be equal to 1. This is not possible. At 0.6 the maximum lean angle is 59 degrees. So if a motorcyclist can lean more than that there are other forces at play. On a flat surface 1 G turns are not possible. With superelevation or banked curves then that is possible.
@@johnspathonis1078 Typically you can add to your downward force with spoilers. Bikes don't have as large ones so they can't go much of 1 G but they can. F1 and drag racers can do over 2 G. The gyroscopic force helps with balancing but it's not powerful to account for most of the crazy lean. You lean because the inertia of the whole bike wants to throw you over the wheels, the wheels just help alittle. Regarding gyroscopic force being damaging. I think planes are a pretty good example of how high radius, high rpm blades can handle sudden torque. A flywheel is best used as a mechanical capacitor though so it would be for stop and go driving anyway. Brake energy recovery is what's important and the prius can already do that. The flywheel is probably just for the quick punch like the 918 RSR has.
Good luck all these wonder solutions. The Cali flywheel bus is so cool though and gyros and rcs flywheel in space are also. Good one as always 2 durp da vinchi, da komrad.
You don't want to use Flywheels in vehicles that have to turn, like Gyroscopes they like to maintain a fixed direction, also a Flywheel on a friction-less surface causes the vehicle t counter rotate.
I want to see the adoption of clothes lines to dry off wet laundry. And not using dish washing machine will save energy as well. Clothes lines for drying out wet laundry are very effective energy savers, because of the fact that electric clothes lines use up a ton of electricity. Clothes lines for drying out wet laundry out in the summer sun and wind have the potential to work much better than electric clothes drying machines. One other thing that can be done is using indoor clothes lines for more personal clothing items like under garments. Indoors clothes lines work quite well for winter time clothes drying. It doesn't take that much time and effort to just hang up some clothes to dry. Also plastic hangars work great on a rack for hanging up dozens of socks. A basement furnace room works very well for drying out clothes on clothes lines in the winter time. Also will add a small amount of needed humidity to home dry air in the winter time, I have had no problems with causing mold or anything like this. We should have solar panels added to the land used up by wind turbines. This would be more efficient use of the spent land wind turbines use. If we see wind turbines we should also see solar panels also set up on the same ground, to more efficiently use up the entire space spent by the wind turbine more efficiently.
Andrew, you are spot on in so many ways! And that is why, regardless of causes, we are screwed. I do think that humanity is very responsible for this surge in the Climate situation. If we are to accept data from the past 300 years, we are the blame for this one. With geological evidence and simple measurements, such as in 2017 a 30 year veteran of crab fishing saw the largest count of juvenile snow crab ever, and predicted 2021 would be the best crop ever, but instead, they actually closed the season. Why? The temperature went up, and they basically cannibalized each other. But nothing will really change. The innate greed of people, as well as the desire for power and control of those that taste it creates monsters that lose all their humanity and they are not able in any way to care about the planet, and certainly not people, especially employees. 90% of current inflation is simply corporations, but far worse, and accelerating exponentially are Venture Capitalists and Merger and Acquisition funds that control most legislation and used Covid to swallow Trillions in free aid, or even zero percent loans.

It's so common now that a 300M Factory only needs 40 to 70 people to run it. They are truly lights out production, and I swear they can run an entire weekend with no more than one programmer, a service tech, and some unskilled labor to load 32 blanks onto their 4 sided pallets that are completely, perfectly finished, robots unload, perform 100 percent quality and inscribing, measure every tool, it's shrinkage, and adjusts the process to compensate for it. The truly wealthy care nothing for the misery of the 99%, or the Planet, and people scraping out a living can't do anything about the Climate.

Do these ultra high energy storage flywheels have gyroscopic forces that resist the rotation of the turning of the earth? As the hours go by, a flywheel mounted vertically will change orientation due to the earth's rotation to a non-trivial extent. Gyroscopic forces would certainly exert pressure on the axis of rotation. Could this contribute to flywheel losses? I imagine that a flywheel storing a huge amount of energy would have to be pointed at true north and tilted to be parallel to the axis of the earth to cancel out this problem, but none of the flywheels you showed in your video seem to be doing that.
It is so foolish for the global warming and climate change alarmists to think doing away with fossil fuels is a good idea. In fact, the accumulation of fossil fuels, biofuels and sequester of CO2 in the ground for a long period of time will eventually lead to a repeat of the largest mass extinction of life on earth like that happened 250 million years ago when massive volcanic eruptions caused huge amount of CO2 and natural gas trapped underground to be released into the atmosphere.
We know the killer lake Nyos killed a large number of people many years ago when the CO2 accumulated at the bottom of the lake released all at once during an earthquake. Since then some smart scientists have been keeping the lake safe by releasing the CO2 from the bottom of the lake into the atmosphere gradually with pipes and pumps.
Suppression of CO2 release into the atmosphere by banning fossil fuels and by sequestering CO2 in the ground is as stupid as suppressing the dissipation of CO2 from the killer lake Nyos into the atmosphere by banning the degassing with pipes and pumps.
I do not ven know if this is a current thing or even possible but... Magnetic bearings for the flywheels? Can't lose energy to friction if there is none yeah? Or even the much harder possibility of using quantum locking (but how would we keep it that cold?)
@@TheWeaponshold magnetic bearings are not lossless. They can induce currents which give resistance that drag on the flywheel.
@@Berkana Eddy currents. You can use windings to reduce that but IIRC that was to redirect the energy not prevent losses. But I would still love to see comparative testing.
I have personally machined hundreds of large rotors and housings for a company called 'Active Power'. It's my understanding that flywheels are used in uninterruptable power situations to provide an instantaneous response to a power disruption, say in a hospital for instance. They are only used for very short times, until standby diesel generators can take over.
About 40 years ago our computer branch ( in very large government department) pulled its electricity supply from a electric generator powered by an electric motor. Sandwiched in between this motor/generator set was a 1000 kg steel disc flywheel. This revolved at 1500 rpm. The purpose of this system was to isolate the computer branch from very short term power loss and electricity spikes.
That is right, normally it is not wisely to store large amounts of energy in an inertia wheel with large angular momentum, because the failure mode associated with bearing failure has catastrophic effects, well documented 70 years ago, when MFO build and operated so called gyro buses having a vertical axis flywheel, which had to be recharged on every stop. They were eventually delivered to Adìs abeba to fulfill Haile Selassie personal oder .
During testing one had a bearing failure, broke out of the enclosure up the test pit and destroyed a considerable number of machine tools on the factory floor, needless to say that the redesign lead to considerable derating of the system, essentially eliminating other customers.
Imagine a carbon nanotube wheel in your car that stores 400 miles of driving energy. It will level buildings when it frees itself.
Not to mention the handling of a car with a giant gyroscope inside. You can only drive level on flat surfaces.
@@mennovanlavieren3885 Actually the gyrobuses had double gimbaled flywheel suspension, exercising no torque on the vehicle on startup the gimbals had small orthogonal torquers to keep the axis upright
@@arturoeugster7228 If the flywheel is allowed to freely gimbal, how is it mechanically connected to a generator or to the vehicle's drivetrain?
Two other things.
The faster you spin a large mass, the more dangerous it is if something goes wrong.
Also, the faster you spin your flywheel, the faster you lose kinetic energy by heating up your lubricant. Also, shouldn't lubricants be worse at lubricating at higher rotational velocity? Fluid resistance is roughly proportional to speed if I remember right.
Good point about the lubricants. It also applies to eddy currents in magnetic bearings-so you'd still be right even if they were using those and not ball bearings or roller bearings.
Kodiak Alaska produces over 99% of its electricity from renewable sources (wind and hydro). They originally used Lithium ION battery banks as their battery storage solution. However, while lithium ION batteries are great for consistent stable power flow, when there are spikes in the grid it puts a lot of strain on those batteries, aging them prematurely. Kodiak is a big fishing town, and the spikes were expected to come from a new electric crane they would use for ship loading/unloading. To solve this issue, they added flywheel storage to the mix. The Lithium ION batteries provided a stable energy output, and the flywheels kicked in to handle spikes in power. To my knowledge, they were one of the first, if not the first public power grid to use both these solutions in tandem. It is still in operation to this day.
Awesome. Great contribution.
85% of 🇧🇷's electricity is from renewables.( Hydro, Solar, and Wind. ).
The company ESS makes Iron Redux flow batteries and it's probably a better solution but it would require good insulation and a little heat applied to the containers for the batteries.
@@Pervatory wind turbines..
Kodiak port wanted to install a new 2-MW crane, potentially causing destabilizing power fluctuations leading to undesirable cycle of the batteries. This is why they got the ABB fly wheel, and an electric crane, displacing thousands of gallons of diesel and millions of dollars of diesel costs. This also reduced the transport of thousands of gallons of diesel in extreme weather conditions. And, lowered the kWh cost to residents.
This brings back memories of UPS beeps, my co-workers' groans and cheers when we lose power and the UPS kicks in for our desktop computers.
#1: No heat? I think somebody's pulling your leg. The resistance may seem futile, but it is still there.
#2: These are likely to be most useful for phase maintenance, keeping fluctuations as various sources and sinks go on- and off-line to a minimum.
Yes. How can something lose 3% of its rotational energy per hour and not generate heat? Where else can that energy go? It doesn't make chemicals, its mass isn't increasing, it's not raising itself into the air, etc. So... it must go into thermal. If it is slowing, that energy must go into heating bearings.
Potter's wheels, spinning wheels, and the so-called "great wheel" lathes we're all examples of flywheels, also sewing machines used to use treadle operated flywheels as well. Basically, before the steam era flywheels were powering a lot of industry
They weren't really powering anything though. They were just acting to smooth out irregular energy flow over a period of seconds. More like a modern capacitor than a battery.
@@vylbird8014 And it was fun to spin up the pedal sewing machines. That didn’t last long. It was fun as a kid, but I learned fun could be curtailed by an angry mother.
i would like a recap/round up on all the 'break troughs' you've presented over the years and follow up where they're at now.
Flywheel plus tidal current in and out. Charge in charge out. Use the current in mechanical and out to charge the flywheels.
I’ve been hearing about carbon nano tubes for at least 20 years! They are always right around the corner to produce at scale. Sort of how unclear has been coming for 20 years.
Me too, but they were called Buckytubes. Not sure about the new branding.
A few commercial products have been made using carbonara nanotubes, mostly sports equipment. We have only known that carbon nanotubes existed at all for about 30 years, so it isn't all that surprising that we have a while before technology developed with them isn't mature yet.
They're the very same nanotubes, that would make the next generations of electrochemical batteries more energy dense as well.
@@garethbaus5471 I think carbonara tubes are some sort of pasta :)
@@simongross3122 That typo is funny enough that I won't correct it.
If they can make them more robust, the best, as you already stated, is using supercaps for storage. Gravity batteries seem to be a better option for now than using flywheels. Just an opinion. Again, until they can figure out a better supercap method, it's gravity batteries to the rescue. Have to have a sufficient way of using gravity of course meaning the space is astronomically much bigger than a flywheel, that is for sure, but at least you don't lose much energy (if at all) from idling. :)
There may be no losses when a gravity storage system is inactive. But it's not as efficient during its active states. The best "gravity storage" is water in the form of pumped hydro storage, which makes up more than 90% of the total storage worldwide and is a mature technology over 80 years old. There are a lot of inactive open pit mines which could be used for pumped hydro storage.
It would be pretty awesome to see small flywheels applied to say a ride on lawn mower, tools that could potentially be "charged" up for the job, and then let run to zero before needed to be used again
flywheels are heavy it wouldn't be practical.
My Grandfather built a telephone exchange power system back in the 1930's and they used a 16T flywheel to rotate using an electric motor with a diesel motor as a backup.
They had a catastrophic bearing failure and caused the 16T wheel to take off out of the retaining pit, through the wall of the power building and down the street of the town.
it ended up in the council hall with no-one hurt, just a lot of damage.
needless to say the next ones had a far deeper Pit under them.
This story isn’t getting enough attention lmfao.
Hilarious, but it wasn't for them !
@@linmal2242 "Oh dear GOD! That giant wheel is headed straight for the pastry shop!"
It's not the only case of bearing failure, In the Textile producing mills of Lancashire and Yorkshire a number of recorded bearing and shaft failures occurred and with Rope Race's or flywheels weighing up to 90 tons the destruction caused was horrendous.
Replacing all Fossil Fuels with Renewable electricity is a great goal, but it’s actually not the first step. The first step will be to get to a “net zero” situation.
According to the book Drawdown, we can actually achieve that while still having about 25-30% of our electricity generation come from fossil fuels. This means that the big push for better battery storage doesn’t really need to yield results until around 2035 (which will give us enough time to deploy it by 2050).
I bring this up, not because I disagree with this video, but because I’ve noticed that many people seem to use the excuse of “electricity storage isn’t solved yet” in order to delay deployment of our current renewable energy tech. The truth is that our current solar and wind tech is good enough so we need to push hard to deploy it as quickly as possible!
Very valid points I think that's generally the Humans adapt just wait for 250$ oil not far off. Holy comment length thoufh batman.
What does the author propose. Net zero but 30 percent fossil fuels? Will there be CO2 capture?
@@RandomGuy-nm6bm there’s not actually any singular solution. The team zeros in on a top 100 solutions which all contribute in various ways. You can find more info on the by searching for “drawdown solutions”. But here’s the gist of the general categories:
- electricity: rapidly deploy current tech with emphasis on solar and wind.
- food: cut our levels of meat consumption down dramatically and convert to cooking methods which use electricity
- Agriculture: restore soil health by no longer tilling. Use methods like composting, tree intercropping, biochar, etc in order to replace current fertilizer usage
- Buildings: aggressively retrofit current buildings with electric appliances, insulation, and smart tech to prioritize energy use.
- Land Use: build nature back up in the areas where we’ve destroyed it
- transport: switch to electric powered where possible. Drastically reduce the amount of private cars by pursuing mass transit and bicycle transit where applicable
- Materials: create more closed loop production processes for key materials.
There weren’t any machine carbon capture points which I can remember but there was a lot of carbon capture which would be done by changing our agriculture methods and rebuilding various areas in nature. Hopefully this answered your question.
It's not good enough.
Good old SAAB 92 (with a drag coefficient of 0.30) from 1949 had a flywheel. In order to overcome the problems of oil starvation during overrun (engine braking) for the two-stroke engine, a freewheel device was fitted. Different application however.
All cars have a flywheel.
@@superliegebeest544 but not like the Saabs ;-)
Pretty sure that a standby loss of 3% per hour can be greatly improved. Magnetic bearings in a vacuum are frictionless in mechanical terms. There are ohmic losses in the magnetic bearings, given the way magnetic bearings are commonly implemented. I.e., with electromagnets driven by variable current controlled by feedback from position sensors. But that's a stupid design. There are better options. Permanent magnets positioned to hold the load at its metastable neutral point, stabilized by low drag dynamic levitation with zero force / zero drag at the neutral point. Great for maglev trains also. You could do an interesting video on that.
Useful to even out the energy from wind farms
I love that you explained the physics behind flywheels, but I think you got a little derailed by the gravimetric energy density numbers. The mass of the wheel itself is unlikely to make much difference in the viability of our grid-stabilizing flywheel energy storage system.
Another possible material is single crystal sapphire whiskers (aluminum oxide)... Currently tested to 10-11 Gpascals with a theroretical for Aluminum oxide of 30 Gpascals... equivalent to te 30 GPascals of carbon nanotubes. they do have the same issue of length as do carbon nanotubes, however they do not have the issue of being burnable.. as they are already oxidized.
I loved my Flywheel tin cars and motorbikes when I was a kid. Nice too see them make a come-back.
Thermosyphoning liquid metals such as mercury through a coil to produce electricity was discovered many years ago. This only requires low grade heat to operate, and there is a gigantic amount of low-grade heat currently underutilized. Imagine the heat from road surfaces for example, or roof spaces, hot sides of structures and so on. The metal circulates around and around and there are no other moving parts and it is said to be 55% more efficient than an alternator. I enjoy your explorations so much, thanks.

" For flywheels to really take off?"
Lol. That 💩 sounds real dangerous, to me!
When you have the NanoTubes you can make a battery using aluminum that is three times as dense as current batteries under development. This research is ongoing in Australia.
What comes to mind about flywheel storage is that it needs to be coupled with something that can store that energy for a long period of time like capacitors for example.
It would only be cool if they made them for Farmers. Cheap, and available packages. My plan is to not spend money on a fly wheel but to use instead what the power companies us now... water storage. The pumping of water to a higher area during the day from solar or intermittent wind systems during the day mean that water can be stored and then released to power a generator later at night. The system can be an enclosed system (same water used back and forth) So this fly wheel idea (something I thought about 40 years ago) whilst cool may just be a side step in the wrong direction. I cant see how this would have space applications either..
Even as a kid, I thought flywheel energy storage was the solution for line conditioning (at a mass scale). Turns out, I wasn't too far off. But what I learned from this video: flywheels lose energy very quickly. I had no idea. I thought it maintained it's inertia in a vacuum very well and took months to lose all it's energy. I was very wrong. That's disappointing.
It's a lot more than 5%. The biggest issue is that cheap power has made people complacent. A lot of things need to change, and you will still need the base-load capacity online to provide the copper base to dissipate harmonics.
A mix of renewables and nuclear are the way of the future. I was in the naval nuclear program and operated a reactor on a submarine, and saw what was capable with good operators and stable design

Second, the problem of long-term storage of nuclear waste is dimply too long-term for the human race. Human lifespan is trivial compared to radioactive waste. We have no experience solving problems with at that time scale. No government or institution has ever lasted long enough to manage this problem.
And Third, it's unnecessary. Solar and Wind can generate more than enough power. Stop thinking about huge localized generation and start thinking about localized generation.

There's a lot going for for flywheels in grid storage but I'm really worried about gyroscopic effects in vehicle applications, it could send someone off the road under some conditions.
They could be placed on hinges , like a gyroscope - but it would make the whole contraption bulky.
I remember flywheels being used on steel rolling mills. e.g. when the mill rolls were at optimal speed from a DC motor, the steel ingot was fed into the rolls. This was a sudden energy requirements which the fly wheel provided. Today, bigger motors and better drive controllers can provide this energy surge.
So the flywheel concept is pretty old and has specific uses.
I saw one huge flywheel in BSC (British Steel Corporation) which was made in Germany before the war. The Germans (maybe Siemens) made 2 and they spent the war years stored in a field. I heard of a turbine generator where the breaker tripped but the steam didn't so it came away from it's holding plate and took off down the turbine hall, through the wall and kept going so spinning objects can be pretty scary.
I used to work on a test rig at Rolls Royce Helicopters where rotor bearings were cycled up to 50,000+ rpm in a vacuum chamber.
GEC turbines balanced their turbines in a huge vacuum chamber and they took up to 4 hours to get up to speed and 4 hours to slow down again.
Ok, irrelevant but the basic technology has been around for yonks and it's great to see it coming back again as new technology is developed. As I see it, it must be applied to the right application. The f1 example sounds perfect.
It is relevant to others that it is a powerful energy storage illustration.
I remember a small documentary show, where they built a small 1 m diameter flywheel and spun it up to speed, they were suddenly very scared.
Hahaha Hahaha 😆
They backed down.
The flywheels shown are sitting parallel to the earth’s surface, but the earth’s orientation changes 360° every day. How do these flywheels cope with the resultant precession effects.
Interesting! I hadn't thought of that. Maybe they'll hang the whole system from a plumb bob string, watch it go round and round! 😄
I feel like it plays a significant role in energy loss
I also wonder what type of bearings are used? Air layer or magnetic levitation or just standard roller bearings?
Also the torque from procession might be able to be converted to power too?
@@LOOGamala I'm sure there is no air, no matter contact
Torus, a company out of Utah, has a home model. The entire system, including solar panels, inverters, etc costs around 50K and is supposed to last for 25 to 30 years.
I did see this concept not to long ago here on TH-cam (go figure) but they were talking about using a super cheap material for the flywheel mass....concrete. a cylinder buried in the ground in a vacuum sleeve, I believe using magnetic bearings.
For grid storage, energy density isn't that important though, is it? Levelized cost is what I'd expect the key figure there.
Yea. I suppose if the axle and container are the most expensive part, a better fly wheel is a good way to reduce cost.
Oh, yes, flywheel energy storage is breakthrough. Wiki: "In the 1950s, flywheel-powered buses, known as gyrobuses, were used in Yverdon (Switzerland) and Ghent (Belgium) and there is ongoing research to make flywheel systems that are smaller, lighter, cheaper and have a greater capacity."
Is the electrical energy recovered from the flywheel system really 90% of the electrical energy used to spin it up? I thought the complication of dealing with variable flywheel speeds while providing stable voltage levels would waste more energy.
So just to keep your flywheel spinning you're wasting 20% of the energy. Sounds like a solution for a very specific problem. Where power is in excess but it might cut out or you might require a spike in power supply.
When a flywheel slows down, I imagine most of the energy is dissipated via friction? Would that not cause heat production, sound and/or material deformation? Assuming the latter is designed around, and the energy losses to sound are negligible, that leaves heat.
Great video Ricky, very interesting!
I live in Canada and I split a lot of firewood every year. I recomended to my community that we buy a 40 ton kinetic wood splitter this year and it is amazing! It has 2x50lb flywheels and the splitting time is 2 seconds per split vs 12 seconds per split for the standard hydraulic splitter. I split tens of thousands of pieces of wood every year so it makes a massive difference! Then between splits the engine is idling on medium low to spin up the flywheels again and so I can split 3x as much wood per tank of gas compared to our standard hydraulic machine. It does cost a little more to buy the machine in the first place but it is well worth it and only a flywheel can deliver that high impact force needed to split knotty hardwoods.
Interesting, I'm planning to build a kinetic splitter at the moment after watching a TH-cam video of a guy who made his own using a Lister D stationary engine to power it.
Considering that his engine only produces one and a half horse power the results are truly impressive.
personally I think in a near future world where we run primarily off of renewable power and use more traditional methods as a backup even today's flywheels fit the bill for that very short term top up while we get the old generators back online
Williams F1 developed but never used in competition a flywheel energy storage system for their F1 cars. They (and all other teams) ran and still run lithium batteries for their energy recovery systems.
Carbon nanotube roll reminds me of the print roll for label machines! 😄 Heavy little buggers.
May I add: that arc discharge system making those long carbon Nano tubds I have never seen and that id game changing da komrad! Whats the source?
Can my comment be seen if so lomi????
It can be seen
I'm sure the flywheel battery is excellent system. By the way why don't you use oil bearing for vertical axis? It has very good lubrication which is applied for turbo molecular pump.
Next question: Maybe you use a DC motor. Voltage of the motor (generator) goes up and down by charging energy or discharging. What is the range? If you use a system of changing frequency
, how do you control the line voltage?
With flywheels, and other solutions, the fact that there is an existing market, bodes well for the future. Its easy to imaging incremental improvements expanding a market.
Full flywheels at sunset is still over half a charge at sunrise, so still useful. Now if only a system that efficient was cheaper than batteries.
Great video! Side note, I didn't realize we had the ability to make 14cm C-nano tubes already. Last I heard they could only make 1 cm long ones. Space elevator possibilities fill my head again. Imagine using earth like a giant flywheel! We couldn't use enough of the energy to see it ever actually slow down. Lots to calculate there.
agreed, there's some promising development happening, and yes space elevators were on my mind too! much to do, far to go, but still exciting
14 centimeters, not inches. You're off by a multiplier of 2.45.
@@castform57 ty! Sorry for the typo.
So, this is Industrial to grid applications, not for personal house item.
flywheels should be in every light post and every building core .. you need alot o fthem to charge fast and dynamically like surge suppression ... flywheels work as surge guard layer .. with batteries behind them ... flywheels should discharge into Solid state batteries if they wont be used ...
When something seems like a great idea, but doesn't exist, there is usually a very good reason why. In some cases, there is a practical or technical reason why it simply won't work. In other situations, that solution only applies to specific use cases, such as the large sand battery used in Finland to provide heat to a community boiler network. This is only applicable where such networks exist or could realistically be built out. I think the same thing applies to the use of large flywheels; they will never be very common because their use case is too specific.
Can't help think that gravity storage might be a better answer. Use excess power to propel a really heavy train up a gradient. When power is needed allow it to run back down and drive a generator as it does. Regenerative braking on a giant scale. When this train is at the top of the gradient it doesn't lose that stored kinetic energy.
I like the lot of mass, slow rotation approach.
grid stabilization, sure. For power storage, the tech is not there yet, and mechanical systems holding huge energy will always be risky.
With the huge amount of investment and research going into carbon nanotubes for this amazing tech, I think it could also have many other groundbreaking uses, like the long dreamed of space elevator. For lighter worlds like Mars or the Moon, it's already achievable, but to start the dream, we need to begin it here first. Amazing content as always :)
the problem with flywheels is they all lose their energy in a day. so flywheels can be used to stabilize solar/wind when is intermittent in spans less than half a day. so maybe a during the night wind and flywheel work together, but if it is a still windless weather and long night maybe the flywheel won't be enough. This is why I believe flywheels are better used for peak time get the excess let the lithium battery discharge a bit and then recharge it with the flywheel.
in grid banks, size shouldn't matter too much, so wouldn't the initial cost be better if they made them out of cheaper slower rpm materials, and just have more?
I really want to know more about this
The one big problem with this is the fact that you have 2700 watt-hours per kilogram of fully charged flywheel just waiting to be turned inevitably into thermal energy in the event of an accident.
It would be like setting off an underground bomb.
Probably wouldn't be an issue if they were sited in remote areas but it would make building an array of them really hard.
well done sir, thank you
What about a material like T1000 infused graphene? Could that be a better material to make a flywheel out of? It's tensile strength would (or should) go up by a factor of 10 (theoretically).
Energy density for flywheels is not particularly important. We have plenty of space for implementation. While flywheels may be low maintenance themselves, the support equipment, mainly the vacuum pumps, will require regular maintenance.
it sounds good with the icing on the cake would be having these flywheels running together with the sodium sulfur storage battery charging this battery as it stores its power where the spinning type charger can take a break you can drop the RPMs once the sodium sulfur battery is stored up to it's maximum capacity where it drops to a certain point then the gyro spinning unit can kick back in to bring it back up looks like it's kind of like the way a submersible pump pumps the water into a storage holding unit when it drops down a float kicks in that turns on the submersible pump see what I mean 🧐🧐🧐🧐🧐🧐🙏🏾🙏🏾💞
Great video as ever, just a small quiblle on the 3% per hour maths - a percentage loss is always a percetage of what you have at the time, so the "a little over a day" is out the window - you were adding them up, giving about 33.3 hours of storage. But in fact, a 100kWh flywheel, after 24 hours at 3% per hour, would be down to about 49.6kWh and losing less than 1.5kWh per hour. After that 33rd hour, it would still have 37.7kWh, losing just over 1 an hour. That's not exactly a massive quantity left, I'll admit, but if you need to be able to access your solar panel power in the evening and you have plenty spare capacity in your panels and flywheel, it's absolutely fine.
If you're interested in how the numbers carry on... after 48 hours, it's 23.98kWh, losing less than 1 an hour. After 72, we still have 11.5, losing .36 an hour. 96 hours, down to 5.5, losing just over 0.17 an hour. It finally dips below 1kWh in the 154th hour - 6 days, 10 hours. From there, the losses start to look a lot like AA batteries' charges and I've no real interest in dragging the formula any farther down my spreadsheet ;-)
Amazing good video! Been thinking about this problem since about 1978. What i've come up with; and I'm not an engineer, is a; 20 -100 max RPM, cascading system that uses compressed air and flywheels. Using a variety of flywheel charging means incorporating several kinds of alternate energy conversion means and devices; you charge; a huge, large diameter flywheel to a point where power can optimally be taken off and used to do work. The function of the horizontal tensile strength of the material used to hold the flywheel, is minimized. It reduces that; power lost at idle, factor. Giant Tapered roller bearings in planetary gear configuration support the multi ton concrete and rebar flywheel. Use three or more in consecutive "planned use" configuration.

F1 does not use flywheels. One team tested it, but was abandoned due to weight. They use batteries for their hybrid systems.
I wonder how well it would work if the fly wheel was attached to a windmill or something of the sort. It would never really go into standby mode that way to lose all that power, but could continue to spin while not in use.
@@KastorFlux I think he might mean using an array of wind generators to keep it topped off all the time, even when demand is low. That's already part of the grid storage designs and in essence the point of using a storage system.
@@Mavrik9000 I did mean this, but I am glad it was explained why it doesn’t work in a way I could understand and not to be an a$$hole. I learn this way.
'Fly Wheel of Fortune' - Good one Ricky!
What happens if someone puts a high caliber round through it? If it is a battery, a small fire which is suppressed quickly. How safe is this?
The wheel sits inside a steel vacuum chamber. The bullet would probably have lost its destructive power before contact with the wheel. CNT is a very hard material, so nothing much will happen there.
But a sudden inrush of air will result in some unpredictable outcome when it gets into contact with the wheel that spins at a high mach number. The air will heat up and might explode, destroying the bearings and letting loose the wheel.
@@mennovanlavieren3885 Sounds dangerous.
Density doesn't really matter for grid purposes. Just cost and loss rate.
Carbon nanotubes don't address loss rate, and their cost is astronomical.
Grid flywheels are best with whatever the cheapest halfway strong material is. Iron works. You're not carrying it anywhere, it can be bulky, that doesn't affect it's utility.
Density could be useful in a vehicle, but it has immense gyroscopic force, and moving vehicles around (against that gyroscopic force) tears up a flywheel, and greatly affects vehicle handling.
The maintenance process alone will make this solution infeasible and the losses in energy due to conversion to kinetic and back not worth the expenditure.
I'm still trying to understand why we would need storage capacity of ONLY 5 percent of the total renewable energy production capacity in order to replace fossil fuels. Intuitively, that number sounds WAY too low. Considering the intermittent nature of wind and solar, it seems that amount of stored energy would not power the grid for long in the absence of wind and sunshine. What am I missing?
Maybe there is some way to reduce the energy loss by using quantum structures in the fly wheels. Especially use some sort of with knots😮?!
How much power does it require to keep a flywheel spun up could it be paired with another storage technique to prevent that loss while not being used? Or is that 3-20% factoring that in? And how are they spun up is it mag lev vacume with magnetic propoltion?
The key is not to depend entirely on solar. The ideal home and municipal grid would have a diverse array of generation and storage options. Each have their advantages. Solar generates a good amount during the day, wind generates all day, tidal/hydro has massive torque potential as well as consistency, and fuel should really be our backup when all else fails not our mainstay generation. To that, chemical batteries are energy dense but high maintenance, flywheels are low maintenance but need a bit of energy to keep their stored energy, gravity batteries are great for long term in my opinion but should be underground for their potential destructive capability if they fail (same with flywheels IMO). I have high hopes for thorium-uranium nuclear and cold fusion but they also should be part of a diverse grid.
Engineers have an acronym for these concepts - PITS - for Pie In The Sky.
All wind and solar should have flywheel batteries, minimally to add grid stability.
How about having flywheels in space spinning in opposite directions and then microwave the energy to safe areas on earth ?
Interesting and what energy to spin them up? Solar in space?
Carbon nanotubes aren't a material. They're a molecular structure. They don't belong on the same list with bulk materials, including all the inevitable crystal boundaries and imperfections. It's like comparing the measured strength of one bulk material to the "strength" implied by the activation energy required to burn another material.
Basalt fiber also has unobtanium-level tensile strength, when you look at individual fibers instead of at structures fabricated out of them.
Also, for stationary applications like utility energy storage, mass isn't particularly relevant. What matters is levelized cost.
I'm a recent viewer, so haven't seen mention of Liquid Metal batteries, on this fascinating Channel, so don't know if the topic has been covered. Antimony/Calcium/Salt, battery operating at 700C developed by MIT's, Dept of Materials Science and Engineering, Dr Sadoway and His Ambri Battery Company based in Marlborough, MA, USA. A variation on electrochemical refining of metals. A site in Nevada, will have a 500 MW battery installed.
Problem with Kinetic batteries, they consist of moving parts.
They might have to use a giant fully gimballed carrier for these flywheels. Unless you place the flywheels flat exactly over the north or south poles.
"Flywheel energy storage systems using mechanical bearings can lose 20% to 50% of their energy in two hours. Much of the friction responsible for this energy loss results from the flywheel changing orientation due to the rotation of the earth.."
The "Gaps between Primes" Mathematical Disproof Methodology applied to chains of axial-tangential resonances in sequence "explains" why horizontal-vertical lines of sight horizons due to relative-timing probability-frequency alignments, limits the stability of connected molecular chains, or the half-life duration of physical elements in general, because everything is composed of log-antilog Conformal Field Condensation, ie QM-TIME e-Pi-i sync-duration connectivity Completeness is a continuous Reciproction-recirculation Singularity repositioning-shaping function. Nothing can last forever except No-thing.
Just as sensational and new now as when i read about it in science magazines in the 80's. Newsflash: any spinning wheel will start to slow down once no more force is applied to it. (unless its floating in outer space)
How about a show on the new developments on OTEC'S.
How does it keep the movement going if no energy is coming in?
to mee it sounds like you want a hybrid power station so that if in the UK everyone starts their kettle you have that flywheel in place to take the surge hit and charge it up again for the next peak of power demand. Have chemical, thermal batteries or like a bit Gravity battery "water?" for the general storage of energy
If flywheels were worth it, by now you would see them in the basement of many homes so you could charge them at night when electricity is cheaper, and then use the power during the day. But you don't. The free market has spoken.
TY for sharing! I've looked into making nano-tubes & they are exceedingly difficult to make and expensive.
Switching electric power supplies are efficient and operate as delivering energy during a timeperiod of then a timeperiod of no power delivered; I wonder if a flywheel can be charged and maintain its energy using electric motors and switching power supplies having a longer off period allowing a flywheel to deliver energy during the off periods
It was easy to guess that is something to do with "Carbon, Nano, Graphene".
Same as ten years ago.
No word to the extreme gyroscope effect in vehicles?
It May Be Possible In The Near Future That Compact Modular Reactors Could Safely And Efficiently Provide Sure Power To Small Cities Or Large Neighborhoods For Many Decades On Their Own Independent Grid.
I don't think flywheels will be practical for vehicles simply due to what would happen in a collision. I imagine an ultra-fast spinning flywheel getting into a major accident cause horrifying damage to its surroundings.
or for instance going around a corner
Just one note, F1 does NOT use a flywheel to store mechanical energy. Maybe the tried it once, but they definitely do not use it today.
Carbon nanotubes are good in supercapacitors. Is anyone working on double dipping? Obviously, you probably want to charge/discharge with the rotor stationary.
The only issue with using a single flywheel in a modern motor vehicle is the gyroscopic effect. This would make the vehicle very unsafe. Perhaps get around this issue by using multiple flywheels spinning in different direction.
The Porsche 918 RSR is a flywheel hybrid. So they managed to do it in a race car no less.
@@willjapheth23789 Hi Will, I accept that. The race car operates on a relatively flat track - no sharp vertical curves. If you check, the flywheel axis is set vertically so that it would not effect cornering. However if it were to undertake sharp vertical turns then the gyroscopic effects would appear. My comments relate to normal everyday use. On an off road 4x4 going over very rough ground conditions the gyro would have to be turned off . Any sudden changes in the vertical plane would cause the vehicle to change direction. This effect is easily demonstrated when a motor cycle turns a sharp corner and the rider leans the bike over into the curve. What holds the motor bike in this precarious position are the gyroscopic effects of the wheels trying to move in the opposite direction.
@@johnspathonis1078 yea hills and valleys matter the most. Doubt the 918 RSR never gets tilted. Also the bike effect is mostly due to the angular momentum of the whole bike not the wheels. Like 1 G turn should allow you to lean 45 degrees regardless of gryo effect. Racers can do more than 1 G turns.
@@willjapheth23789 Hi Will I don't know if your a mechanical engineer but I have designed vehicles to comply with national design rules (ADR's). In vehicle design they talk about friction utilisation factors (basically coefficient of friction.) A very good coeficient of friction is 0.6. To pull 1 G the coeficient of friction must be equal to 1. This is not possible. At 0.6 the maximum lean angle is 59 degrees. So if a motorcyclist can lean more than that there are other forces at play. On a flat surface 1 G turns are not possible. With superelevation or banked curves then that is possible.
@@johnspathonis1078 Typically you can add to your downward force with spoilers. Bikes don't have as large ones so they can't go much of 1 G but they can. F1 and drag racers can do over 2 G. The gyroscopic force helps with balancing but it's not powerful to account for most of the crazy lean. You lean because the inertia of the whole bike wants to throw you over the wheels, the wheels just help alittle.
Regarding gyroscopic force being damaging. I think planes are a pretty good example of how high radius, high rpm blades can handle sudden torque. A flywheel is best used as a mechanical capacitor though so it would be for stop and go driving anyway. Brake energy recovery is what's important and the prius can already do that. The flywheel is probably just for the quick punch like the 918 RSR has.
What percentage of a fly wheels output is needed as input to get it spinning up to 50,000 rpm?
1:11 Interesting: every new energy source just comes on top, none is ever phased out for a newer one.
I’d like to know industrial production of carbon fibres in terms of raw materials used and energy usage. Can C from atmospheric CO2 be used?
Good luck all these wonder solutions. The Cali flywheel bus is so cool though and gyros and rcs flywheel in space are also. Good one as always 2 durp da vinchi, da komrad.
You don't want to use Flywheels in vehicles that have to turn, like Gyroscopes they like to maintain a fixed direction, also a Flywheel on a friction-less surface causes the vehicle t counter rotate.
Where do I get li-ion batteries with a 90% discount?
I want to see the adoption of clothes lines to dry off wet laundry. And not using dish washing machine will save energy as well. Clothes lines for drying out wet laundry are very effective energy savers, because of the fact that electric clothes lines use up a ton of electricity. Clothes lines for drying out wet laundry out in the summer sun and wind have the potential to work much better than electric clothes drying machines. One other thing that can be done is using indoor clothes lines for more personal clothing items like under garments. Indoors clothes lines work quite well for winter time clothes drying. It doesn't take that much time and effort to just hang up some clothes to dry. Also plastic hangars work great on a rack for hanging up dozens of socks. A basement furnace room works very well for drying out clothes on clothes lines in the winter time. Also will add a small amount of needed humidity to home dry air in the winter time, I have had no problems with causing mold or anything like this. We should have solar panels added to the land used up by wind turbines. This would be more efficient use of the spent land wind turbines use. If we see wind turbines we should also see solar panels also set up on the same ground, to more efficiently use up the entire space spent by the wind turbine more efficiently.
Andrew, you are spot on in so many ways!
And that is why, regardless of causes, we are screwed.
I do think that humanity is very responsible for this surge in the Climate situation.
If we are to accept data from the past 300 years, we are the blame for this one.
With geological evidence and simple measurements, such as in 2017 a 30 year veteran of crab fishing saw the largest count of juvenile snow crab ever, and predicted 2021 would be the best crop ever, but instead, they actually closed the season. Why? The temperature went up, and they basically cannibalized each other.
But nothing will really change.

It's so common now that a 300M Factory only needs 40 to 70 people to run it. They are truly lights out production, and I swear they can run an entire weekend with no more than one programmer, a service tech, and some unskilled labor to load 32 blanks onto their 4 sided pallets that are completely, perfectly finished, robots unload, perform 100 percent quality and inscribing, measure every tool, it's shrinkage, and adjusts the process to compensate for it.
The truly wealthy care nothing for the misery of the 99%, or the Planet, and people scraping out a living can't do anything about the Climate.

Dish washing machines use a lot less hot water than you would by washing and rinsing manually. Sometimes water is more precious than power, although that depends on the region. Most residential energy usage goes toward HVAC, so better insulation and more efficient heat pumps would go a long way.
