The young lay said it all. It's not a competition of renewable energies but a collaboration of all of them together. Keep up the great work.
Don’t be naive everything is a competition, that’s literally the theme of life on Earth and anywhere else it may exist.
This technology means big money and without proper commercialization and competitiveness with other forms of energy extraction technologies, it won’t catch up.
This is where we let capitalism do what it does best, innovation and cutting costs for the consumers.
@@mankind8807 "Innovation" and "cutting costs" are two incompatible ideas. You can't do innovation because it is by nature expensive and unprofitable and cutting corners will certainly lead to the innovation held back...
@@axelpatrickb.pingol3228 What? Do you even know how markets work? "Innovation and cutting costs are two incompatible ideas" ??? "Innovation is unprofitable" what???
You need some schooling, here it comes, under a monopoly, there is no significant drive for innovation, or for the companies to reduce the price of their products. Under a capitalist market, companies have to compete to provide for the best and most cost effective product, otherwise they are out of the competition, competition drives innovation and product cost effectiveness, the end result is that the final product is of high quality while being efficient and sustainable, therefore it costs less for the customers to buy and the companies to produce.
Literally any piece of technology around you could serve as an example for innovation and cost effectiveness, but we will take the example of Spacex Falcon 9 vs The Soyuz, spacex innovated on rocket reusable technology and now it saves customers such as Nasa $35 Million less in comparison to the Soyuz, not only that but the quality of the service is almost 10 times the value of the soyuz.
I don't really know where you get the idea that innovation isun profitable, it's literally the name of the game for capitalist countries, and all modern products you see today are due to innovation.
Innovation is always synonymous with improved quality and effieciency, and efficiency cuts down costs for both the companies and the buyers.
Maybe you were saying that it costs more money for a company going through innovation process, which duh ofcourse it does, it's called an investment, but that stuff you mentioned about innovation and cutting cost being incompatible and innovation being unprofitable is complete bull, gotta see the whole picture and think in the long term.
It's all balance. Both collaboration and competition are needed
@@chrispark8303 You mean the same Henry Ford that makes the Model T AGAINST market trends, that REFUSES to change anything about the car even as simple as a paint color, and makes his displeasure of "change" very obvious by destroying prototypes like the one time he sent a new engine down the scrapper IN FRONT of the engineer who designed it?
If you ever know Henry Ford, you would not have used him as an example of innovation since at the later part of his life he is EXACTLY its antithesis. He thinks he IS the Innovation and refuses to take suggestions from anyone else. Do you know that Ford used to have a 90% market share by the 1910's only to have it reduced to less than 40% by 1927 just because he refuse to change anything about the Model T?
As a Energy and Power systems engineering student, all I can say is these are the kind of projects I want to work in future.
to convert wave to rotary/turbine: what about pistons “knuckle-rodded” eccentrically, to wheels; reverse locomotive style? then, maintenance is still extraordinary....
"Energy and Power systems engineering" is there a way someone could get into it from scratch?
Oh, the ones that will laughed at in a couple centuries?
Wave power is the renewable that makes the most sense if they can figure it out. It never stops and most big cities in the world are near the ocean.
Have you heard the numbers? If the US exploited _all_ wave energy along both of its coasts, that would still satisfy only half of its energy needs. This will always be restricted to niche applications.
But, yes, a magawatt wave generator is still a megewatt less of coal.
@@bazoo513 First of all 50% is not niche. Second of all how much of the east and west coast energy needs would be fulfilled?
Use all of renewable Energy sources at the same time put panels on mercury as a Dyson sphere prototype until we reach interstellar civilization
@@sumreensultana1860 We have _lots_ of porridge to eat (as my grandma would say) before we are capable of such a feat. We can't even agree on using our deserts to harvest solar energy. With intercontinental terawatt scale grids (which have only political, not technical issues) and use of parts of all large deserts (from Atacama and Mojave, to Sahara and Namib to Saudi "Dead Quarter" to Gobi to Australian Outback) we could have a huge excess of guaranteed 365x24 solar power. No need for even LEO solar collecting satellites (which were seriously considered as recently as late '70s).
@@bazoo513 Not only that, sea of Japan and Baltic seas for off-shore wind, Siberia for onshore, Scandinavia and South America for hydroeletric, Italy, Japan and Portugal for geotermal. If we manage to build an intercontinental grid and use land with the maximmum efficiency possible we will drasticly cuts emissions
What the hell, the wave roller is 20km from me and I never heard of it.
Think of all the other things you're missing out on.
@@creativemindplay punane
My friend, you should raise awareness about this around where you live, I bet If you dont know about this then others wont know too.
You could be a real force for change.
@@ruaidhriyea376 are you threathening me?
May be because it's hidden underwater......
The problem with this is the massive maintenance costs due to the corrosive nature of seawater
I am happy to see least one person who could consider the matter in a wholesome manner. People generally don’t think about the returns from an investment taking into account the lifecycle of the system. Most people jump on to the next energy idea not thinking about the overall ROI. The scientists behind these “great” ideas are intelligent people but they don’t care about the wholistic returns from the system in the long run.
The solution to that is called...... Plastic... Of course there are difficulties.. But if they can come up with a solution then they can use all the recycled plastic to manufacture the parts
@@Srikanth_CVA or they could use PLA which is made of corn starch although it does have it's drawbacks
The real problem is.... Most of the design in this video don't even work.
@@nirui.o Would say it will work for demo or POC but for it to pay for itself is the most difficult challenge. I already notice the shore generator rusting
A very strong engineering plastic is definitely needed.
Seems like a maintenance nightmare. The place with the most energy is probably the most deadly. Not to mention the non-linear motion would be very difficult on equipment.
At least one person who can think. Most people jump on to the next fad not thinking about the overall ROI. These scientists are brainy people but they don’t care about the wholistic returns.
8:01 that friction is awful
Water erodes and damages equipment significantly faster than air. This is not a hydro electric dam where they can just replace the turbine, this whole thing is underwater.
@@UnsaltedCashew38 I think the devices that float on the surface are more feasible.
Not true electronics frictionless bearings pure kinetic energy is available. only temporary scientist are diverted. To mars.
I would LOVE to work in this industry 🌊
It would be wonderful to see wave energy come to Hawaii. We have an abundance of optimal locations for such projects, but currently only a single test project exists at a military base.
That is the EHL Solutions Azura prototype. They're building a bigger version at the moment.
Except that peak production of wave power doesn’t match peak consumption periods, so it doesn’t really make sense to me to invest heavily in a technology that at best will serve as a supplemental supply to carry for low periods of consumption.
And it’s not like this will really change as it’s dependent on the tidal forces of the planet.
Hasn't one of the impediments of greater solar adoption in Hawaii been the Hawaiian utilities who have imposed restrictions to avoid solar generators' loads on their systems?
@@brian2440 Agreed and that is why either storage solutions or sale to other places needs to be sorted (interconnectivity of the grid, which is what the EU is working on). Have a look at Tony Seba's latest "lecture" on this on TH-cam, he can explain this much better than I can.
CCE
*The Japanese company Mitsubishi already developed something similar but even better more than 35 years ago...and can be placed in a small lake...pool...etc...without needing any external wave or wind...*
what
If these projects got a fraction of the funding seen for fusion energy research, all design issues would have been solved decades ago and they would be everywhere today.
I have been hearing this for forty years. It has yet to materialize due to the harshness of the environment.
With those 40 years came substantial increase in material science and with the progress of better computers/ quantum comps come even better under standing and material combinations. What im trying to get at is we continuously progress it might not seem like it but one of these days someone will crack the code or advancements in other fields will bring answers.
It took 60 years to go from a glider to the wright brothers first flight. Give it another 20 at least.
Nah give it a 12
Have a look at EHL Solutions New Zealand, they are building a Azura wave energy converter as well.
As a veteran in oil rig, I can inform you that offshore works will cost you at least 3x than onshore ones.
Materials will be costly and short lived. Operation will be dangerous and (again) costly.
For me, nuclear and hydro-power (dams) are the answers for sustainable energy generation.
She is extremely impressive...stay at it young lady!! People all over the world are rooting you on!!
With all the energy these people are putting into the technology, I foresee a wave of these projects in the future.
ayy
I foresee a negative capacity factor.
Beautiful. We can be friends
showing an accurate and deep understanding; great perceptive. Thank you for all the insightful information. 💡
This technology could be placed on or near existing off-shore wind turbines so they could tap into existing electrical infrastructure.
Brilliant comment, and I totally agree. I hope companys think of this.
the idea has already been discussed within the offshore wind sector around 2010
I had an idea like this for wave energy. It was basically like fishing except instead a fish pulling the bobber down under water it was wave energy. The fishing line was attached to the ocean floor and the line pulled a dynamo (or alternator) on land.
nope
nope, try again
그런 기술 이미 있는데
로프의 유격과 반사파도 때문에 효율적이지 않다
Very informative, thank you for creating this video!
"The only battering rams in use today belong to SWAT teams and Police. The smaller of the two pictured below is 30" long, weighs 35 pounds and packs an impact of 19,000 kinetic pounds, while the larger one is 40" long, weighs in at 50 pounds and impacts with 26,000 kinetic pounds !!
Does anyone still doubt the power of a swinging ram the size of a bus, in the hold of a ship ?
Or perhaps 20 of them in the hold of a ship ???!!!!"
This is great, hope the technology reaches maturity in the next couple of decades. We need as much clean energy as we can produce (or harvest).
agreed.
Wave energy is such a cool idea. But the problem is its so hard to capture most of it
it has its ups and downs, right?
@@aleattorium More like highs and lows.
Build Machines to create waves maybe, and use it as a cycle to keep powering it. Idk I'm not a expert, idea seems easy, but to bring it life is obviously the challenge
@@CosmicHarmony58 no perpetual machines does not work the amount of energy to make the wave will be higher compared to the amount you gain unless it's in a vacuum then the amount you use is the same with the amount you gain so you are just making a really expensive perpetual motion machines
@@CosmicHarmony58 the principle is that the efficiency of a system will never be 100%, because of friction, vibration, etc. But as long as the world keeps spinning, the tides will be moving too.
Question: are existing offshore wind towers symbiotic mounting foundations for future wave energy installations? Seems like they could offer a huge and relatively stable surface area.
Most probably not. Energy capture from waves depends on movement by an oscillating water column. Wind turbine moorings stabilize the platform.
It could be possible to leverage existing generation and/or transmission capabilities by co-locating wave energy capture devices with wind turbines
I can’t wait to get started on this
When did the issues identified 20
years ago go away? The issue is economical. The sea is too corrosive. It will be expensive to maintain. This will be a reality when energy prices go above the roof
I know some hydroelectric superprojects use some of the energy to produce an electric current going through the corrosion-prone parts to avoid this problem, don't you think it would work in the sea ?
Great idea!
Could be great to harvest the power of the wave colliding with the shore, like having a recurved wall that would be pushed back and forth horizontally when the wave hits it. Such thing could be used all around the seawalls protecting harbors and on the shore where the right conditions (currents, etc) are met.
Great concept !
The ‘shock/impact’ of a moving object is far higher than the static load of that same object.
(A hammer hitting the head of a nail [or the nail on your finger 🥴] is an example of this phenomenon.)
👍🏼
Visually beautiful and truly informative video! Thanks!
Nice cherry on top of this piece w/ the added animations
Well done!
OPTT looking hot rn
This was a really nice voice over voice/person:-)
What about the dozens of companies over the last 25 years that went broke trying to make this work?
I mean they mentioned it and they explained exactly why and the whole video is a response to that point 😐
past failures also dont matter you keep trying year by year generation by generation, and eventually we will figure it out like we have with other energy sources/ tech maybe we still dont have the required tech to pull this off. However sooner or later we will.
@@aujulon You could be right. They seem to be using the same engineering as past attempts. As an investor, I would not put my money into this project.
@@aujulon I disagree, most ideas are bad and eventually fail, only a tiny fraction go on to be successful. Geothermal has similar theoretical generation potential, but is too expensive in practice.
Although I hope wave energy extraction becomes economically viable and used extensively where appropriate, this has very little to do with reducing carbon use. The reality is that wind + solar + hydroelectricity etc are already cheaper than fossil fuels and the main thing stopping an instantaneous transition is simply the time it takes to deploy, and the resistance of entrenched businesses and the political pressure they put on governments together with the fact that closing an existing, fully operational power station may not be economically viable. But we will see almost no new coal/gas power plants being built around the world and existing ones will be phased out over time. This will happen and it will happen for primarily economic reasons. If governments want to accelerate it they need to stop subsidizing fossil fuels.
No. The reason why our way energy production hasnt changed completly is availability. Electric power is time dependent and cant be stored buy sending it in a circuit circle, fossil fuels do not have that time dependency thats why they are much more convenient for peak power draws etc. .
Also a problem is the powerstorage per volume ratio in electric transportation solutions. Fuel has around 8000 Wh/l while Li-Ion Batteries have a max of 590 Wh/l.
Im all in to abandon fossil fuels (there is just no way to make them fully sustainable due to the high entrophy once they get released into the atmosphere) but with "technology" like potrayed in that video we wont be able to cover our power consumption by a bit. The only possible way out for our biosystem might be fusion energy or fission of more common elements.
Gas turbines are actually on a rise at the moment because they help to cover short term demand when there is a cloudy day without wind.
@@Quntes You are not even close to being correct. Some parts of the world have already transitioned most of their grids to renewables without catastrophic failure, other parts of the world are still lagging behind. Almost universally the delay is political or merely the time it takes to build new stuff. Sure, for a grid to be entirely dependent on solar/wind does require some storage in the mix, but many countries do not require to have 100% wind/solar, and wind+solar+storage is starting to be cheaper than fossil fuels in many cases. Here in South Africa, the delay is entirely political (the entrenched power producers have political power) Another important factor with wind/solar is you can over provision which lowers the storage requirements and produces vast amounts of extra cheap energy boosting the economy. As for transportation, the density issue you mention is not a problem for cars, the current issue is merely building out the infrastructure for manufacturing batteries. For aircraft and ships density may be more of an issue, but lets do the easy wins first then discuss the harder ones later instead of blaming density and ignoring what can easily be transitioned.
@@TimothyWhiteheadzm Australia,SA and many other places might have the benifits of having a lot of sunshine and enough locations to use hydro powerplants as energy storages but there are plenty of other countries which do not have those benefits at hand. Right now Germany has the highest cost per Kw/h because the amount of new infrastructure to provide stability throughout the country costs a lot of money which leads to many companies transitioning to different location due to its increased production costs.
I do prefer sustainable/renewable energy, yet there are so many problems involved that you cant just "decide" to switch to a different way of power production.
Bro India and China alone or expanding coal faster than the rest of the world is expanding their total energy production
Excellent overview in this video with really inspiring people on the subject that gained knowledge after limitations found in the past. Keep it up and really wish you best of luck with this renewable source or with the harvest systems, next to others. We need all sources. Well said by the lady originally from Ukraine.
The Pelagius Wave Energy Converter were Wave Energy projects on large scale was first in stalled off the coast of Scotland in 2004 and off the coast in Portugal in 2015, but both companies involved filed for insolvency shortly afterwards
Thanks. Inna Braverman is entirely correct. It's going to take every possible renewable energy source, used appropriately in its best niche, and working together, to create a true renewable grid. I'm very interested by Ms. Braverman's project in Tel Aviv, because it reminds me that such a system might be used (at least partially) to run a desalination plant. Such plants are going to become an increasing necessity worldwide in the coming decades. Ultimately, I would like to see wind, geothermal, wave, hydrothermal, hydro-electric, solar, and yes - nuclear too - become viable parts of our energy landscape. 𝓡𝓲𝓴𝓴𝓲 𝓣𝓲𝓴𝓴𝓲.
What can we learn from the off-shore oil drilling industry? How do they deal with corrosion for years/decades? Or are these totally different problems without much overlap?
Simple, they don't!
Oil industry don't use Moving parts. A drill is used , then thrown away.
Oil industry is neither durable nor sustainable.
This is absolutely true for the last 50 years, at least.
great video 👍😮
This is amazing
Wave and tidal power are more reliable means of getting consistent power than wind or sun.
I wish we have that in the philippine. We need that technology.
Love it! I love all the new renewable energy stuff. I think I seen city or town running off of a hot spring.
Epic work
Placing generators on the coast seems like a maintenance nightmare. The underwater Push-Type looks interesting but probably needs a lot of work on the output to make it stable as a real world grid source.
There's a beach on earth where there is no trash ??? woaw that has been the major discovery for me in this video lmao 1:45
Okay this is great, get it bloody going! What are we waiting for?
Brilliant!
Wave-Energy will be the solution to the world's energy needs. Let's hope they can overcome the technical issues, and make it work.
Or maybe I don't know, build 1 nuclear reactor and save all of the "Big Leap" ??
Nuclear reactors take decade(s) to build. We should build more nuclear capabilities, yes, but we cannot dismiss other energy sources. At *minimum*, we need SOMETHING to power us while we wait for new nuclear reactors to be built.
1 nuclear reactor isn't nearly enough, either... We need hundreds to thousands.
One thing we could be doing is to keep our existing reactors running. Sadly, some places are prematurely decommissioning nuclear reactors because of public fears...
@@ThomasBomb45 Nuclear reactors only take so long because of public resistance. If people accept nuclear power more, we could be fully clean energy in 20 years.
@@ginsederp YES!! and with the development of better safer reactors like the thorium reactor that can not have a meltdown due to the design we essentially eliminate the risks
Lol yeah but u will need to sell tim cook
@@sufferr2914 yeah
Floating, mobile ones would be amazing. They could move with the tides and or sea levels. Harnessing the Earth's energy in a harmonious way then most. Geothermal is great when applicable as well
8:45 "automatically raises the floater in a storm" - video shows floaters on water being tossed around
Those on the right of that pier were raised out of the sea, those being tossed around demonstrate why it's necessary to raise them in a storm.
brilliant!
MORE VIDS LIKE THIS PLEASE
Interesting and useful too considering the ocean is always creating energy
I wish them luck and success
didnt they have wave energy in the film south land tales.. that was such a strange film, with a great message
Waves and currents...of course
8:45 Should not every floater be raised in such conditions..😬
They should use wave rollers for sea walls in places that are sinking
Hot outside? Just put A/C outside. Problem solved. smh
Love the potentials of wave energy. Will be interesting to see the work of engineers over the next few decades to improve it.
Energy production isn't really the issue, its energy storage, once we figure out grid sized energy storage we can wave oil goodbye .... my money is on the Air battery, scalable, long lasting and cost effective.
Long term cost and maintenance is the problème. Power and efficience are the problème!!
one day we gonna see a sea full of this, thus capturing more trash in the sea
This is amazing! Keep this up guys!
Yep, the rotating of the earth is our biggest generator of energy, in a scale no one can imagine.
The idea itself is very interesting but I fear that, even if developed to a high efficiency level, almost no state wants to block their coastline by placing these generators on/near the shores. After all, beaches attract tourists or serve as harbours.
Nevertheless, if these devices could be placed further away from shore and overcome all of the maintenance and grid problems with superb efficiency, then they might have a chance in my view.
Big respect to what Inna is making. We need more woman in STEM. Let's support her!
No, what we need is the best and most passionate people for the job in STEM. Regardless of genitalia
I heard that that bending a carbon fiber in a solution, I think sea water could work, can produce an electric current, my idea is to have kelp like-structures in the ocean, and they can generate electricity without disturbing the environment, if you put it in a rubber skin, you could prevent any marine life from trying to eat them, and allow us to use a more high energy solution at the same time
Tsunami be like:Look at me I am the energy
Wave Power Could Be Energy's Next Big Leap - Bloomberg around 15 years back!!
Some of the ocean's tidal energy is actually transferred to the moon, allowing the moon to accelerate in its orbit around the earth and thereby increase its distance from the earth. That's how the moon was able to reach its current orbit. Tapping the wave and tidal energy of the oceans would have a significant effect on this process. It would also greatly interfere with ocean currents such as the gulf stream to a much higher degree than CO2 ever could. If too much energy were drawn out to generate electricity it could literally rob the ocean of the energy that it needs to stay alive. Coral would die all over the planet along with the reef ecosystems. Ocean temperatures would rise and oceanic oxygen levels would decline. The ocean could become stagnant.
I think trying on large rivers like the Nile and Congo rivers would give a large output of electricity
Hydroelectric using rivers is well established, it tends to be pretty awful for river ecology.
@@alexhamon9261 using dams is harmful to the river ecology, this however wouldn’t cause the turbines would be submerged, the Nile and Congo rivers are large enough to have them submerged
Eh, there's already the aswan high dam and the new Grand Ethiopian Renaissance Dam in ethiopia.
Amen to you sister

But as recent studies show, all "renewable" energies don't cool down the planet directly, unlike coal/gas/petrol which do.
what studies
"Hopefully one day it will be competitive with solar and wind". If it can't compete with solar and wind which are low energy and low maintenance generators, this tech is going nowhere.
Heterogeneous solutions have a resiliency that is easy to underestimate until disaster.
That last statement 🖐
I’m in on this
Solar and wind are nothing compared to the size and power of constant waves and currents.
Yes. I confused wave energy with tidal stream generator.
Check out Wello's Penguin wave power plants
If I may paraphrase the saying, “wave energy is the renewal energy of the future, and will always be”. I have been reading about wave energy since the 70’s (such as the Salter’s duck), but none has progressed to large scale commercial generation. In that time, several companies pioneering this technology has gone bust.
That's fusion energy
I love technology, 😭
Water is 1000 more dense then air, using the pressure of water is a no brainer.
They can use wave power to operate a water ram that moves water to a higher elevation in large quantities. Then you can use the potential energy difference to power a generator.
wave energy = such a cool vaporware.
But aren’t there steel types that are resistant to corrosion in salt water? I’ve heard about knives for divers made from a specific type of steel. And then, ships have a lot of parts that are constantly in contact with salt water and don’t seem to corrode. Anyway, I hope real experts do their best to make this technology real, it looks like a great idea.
Ocean power technologies. Buy now
I've been saying it for years, just drill into the earth there is magma, if you put a pipe down there and loop it back to the surface, you can put water in the pipe, the magma will turn the water into steam and you can use the steam to power generators. it's "limitless" - why no one has done this I have no idea.
They have done it. Geothermal is a major source of energy in Iceland (25%). It's easier to access there because the island is basically a big volcano.
@@zivkovicable obviously I mean other places
Interesting
I'm working to make it happen, it's been 2 year's now.
4 years....its incredibly expensive, that's why no one wants to do it.
He in Puerto Rico it was considered but the maintenance was prohibitive. Corrosion.
We can make waves, we can break waves, but why can we not "use" waves?
Wonder what kind of consequences there will be for the animals that need strong wave motion to survive. Not to mention the shoreline and ocean floor is just as fluid as the waves.
Wouldnt using some sort of turbine that uses wave energy to add to its rotational speed be better than using some sort of fin or flap?
Check out Minesto
Better for tidal energy generation as I imagine sustained periods of rotation are needed to maximise output (if the waves keep going back and forward the turbine probably doesn't have much time to build speed).
How much oil money is opposed to these alternate energy projects? How much funding and subsidies go to fossil fuel as compared to support for alternate energy of all kinds? Why is so much investment going to exploratory drilling for oil in ever more harsh and fragile locations when there are so many existing proven fields? These are the questions that need answers. Generating power through alternate methods would happen overnight if the will to do so existed.
The only way this system will ever become a large power producer is if some major sociopath or a bunch of lesser sociopaths believe they can rack-up massive profits off it. All Hail Money!
Minor thing, in the subtitles there is a slight mistake in the Chernobyl year, 1986* not '96 :)
