They have always been and will continue to be very high-maintenance devices. Sediment, wildlife, algea and the thousands of different bits of junk that gets flushed into water clog and deteriorate these things like nobodies business which demands a balancing act of filters at the cost of output. That and the catastrophic failures that occur once there's a dry-spill which Sweden was recently devastated by, causing energy prices to go up by 1000%+ due to over-reliance on water-based energy.
@@Runefrag ^This You put stuff in water, Stuff will inevitably get F*d up because water is great for everything except machinery. Mixes with anything and everything, everything alive needs water to live meaning that water inevitably has a bunch of living and dead stuff in it which eventually clogs shit up. Since it mixes well, it pretty much always becomes corrosive or acidic. It's also pretty heavy stuff which means that it both loves to carve its surroundings up and transport heavy stuff downstream. Anything built in water needs to be overly solid to account for all kinds of hazards and yet it'll still inevitably degrade and break at a faster pace than any engineer would ever want. Water sucks to work with. It's really good stuff though.
Hydro power has been in use in Scotland for at least 50 years now, did no one know this. 99.9% of electricity in Scotland is by renewable energy and over 60% goes to England
Scotland has a huge land area for less than 10% of the population of the UK, with lots of high ground & valleys that are ideal for this kind of equipment. Scotland also has far higher wind speeds than the rest of the UK, which is why the wind turbines have better production figures. Much of the energy has to go to England because Scotland cannot use it all & transmission losses, for exporting further afield, are huge. It flows the other way when necessary. Scotland spends some £8 billion/ year more than its tax receipts & that includes credits for the oil & gas receipts. That gap is filled by England, along with similar subsidies for N.I. & Wales. Most of the technology installed has foreign investment at its source, that has to be paid for somehow. Norway started hydro-electric at the end of the 19th century, with Hammerfest (north of the arctic circle) being the first town to benefit from electric street lighting in 1891. So Scotland wasn't exactly a pioneer in the process. That aside, there's still a long way to go before oil & gas can be dispensed with, with something like 3 billion people in the world reliant on burning dung or wood as their sole source of energy, causing millions of deaths from smoke inhalation, cold & food shortages. They need cheap energy & the holy grail that consists the current & proposed 'renewables' aren't going to be anywhere near enough to fill that hole.
Being in S.W. Indiana local people have often wondered how come the river current has never been used. With this method would indeed be an excellent place to start. Multiple turbines at points along the river at different depths.

You do know putting water through a turbine cracks all of the entrained gasses out of it ! With no oxygen in the water, all of the organic decomposition is anaerobic and produces extremely toxic compounds!

One factor that mitigates the initial higher KWH cost of off-grid solar is it allows local distributed production and consumption. It is easily scaled up,then forming micro grids. That cuts out the slick-dressed parasites that run the grid,whatever the initial source of energy.

I agree. Ammonia based turbines are amazingly efficient and all you need to do is let a pipe full of Ammonia gas heat up in the sun and it rapidly expands, flowing past a turbine down through the pipes heading underwater where the cold water cools it so the cycle can begin again

A topic to consider is that demand for electricity is not flat but typically is higher during daylight hours than at night. With a dam, the reservoir acts as storage and replaces the battery.

Thanks for this interesting explanation along with the interesting fish-friendly propellers Ziroth. By placing big rocks all spaced along the waters edge this will considerably slow down the bank erosion as well making it truly nature friendly.
Maintenance, is always he maintenance that tips these project up. I remember the the wells for Africa project. They couldn't even look after a simple hand operated well pump. Some of them ended up fighting over who operated the well. Although they will be good for remote areas where there is sufficient infrastructure to repair and maintain them.
It happens everywhere, hope it ends up in peace and restoration of operations?❤, gopidas is a veteran of many such failure and recepiient of dusappointments
Each and every facility to evolve it's very own maintenance schedules, of preventiveoeriodicovehaul time tables and activ y, often augmented based on local experience?
Likely because it's mostly bullshit. Picture this: Hydro dams and turbines have been around the block for a LONG time. Now, an amazing genius new cool idea pops up that nobody has ever thought of before! What's the idea you ask? Slightly differently shaped turbine blades in a smaller form factor! Do you still believe that this "new amazing cool genius idea" is something new and revolutionary? It's definitely been done before. It definitely already exists and if there aren't hundreds of similar versions of this out there in the wild already, then there's probably a good reason behind it. Spoiler: They do exist, but they require so much maintenance that they're an awful investment. Water clogs and corrodes anything it touches over time.
I'm not clear on what makes this turbine "genius". It seems almost identical to other turbines out there for smaller installs. The video comes across like advertising for Natel Energy given the number of times they are mentioned.
We were told that energy would be come super cheap with wind turbines. In the UK you can’t get moving for wind turbines yet energy prices are at an all time high? Bullshit.
the tech is here and has been for a few years now . we need to at least start the work to transform to renewables. we all need to put pressure on the ones who are in authority to get this going! And it needs to be now!!
hopefully these can get installed in regions around the world for cheap energy from local watersheds. hopefully around middle america harnessing the rocky mountain watershed hydroelectricity
This is a great point, but the big grids needed to stop large logs and mammals are much easier, cheaper, and slow water less than fish screens - I should have mentioned that!
The answer that these companies overlook is using bladeless generators inside sewage pipes. People are constantly creating waste, and yet very little (basically none) of that energy is recouped. Waste products are sometimes harvested for gases, or turned into fertilizers, but the kinetic energy created by transmission from the home to the treatment site is never collected (if at all). There's tremendous hydro-electric potential if only waste were managed better.
I am not a pro when it comes to HE turbines, but I showed this to a friend who was an electrical engineer in charge of all regional operations for GE. He was a german old-school pragmatic SOB. He categorically disagrees that this is possible, based on math and physics of all previously designed HE turbines. Any thoughts?
You’d think these would be used inline of water tower outlets that feed cities, you could put 50 inline. You could downsize it for in home use on the water in-line connection. They could connect to heating elements to heat sand batteries to heat the house and or hot water.
@@Screw_This I´m wondering what difference big wind farms do to the enviroment, by taking kinetic energy of wind. It must have some effects, but there is almost no talk about it in mainstrem.
Misses the effect mollusks will have. Shields to protect fish will be the perfect place for them to settle which means regular maintenance. So what is the solution offered … likely expensive replacements as maintenance will be abandoned.
Only effective as long as the water flows. And reservoirs and rivers have a tendency to dry up and reduce the flow rate in hot weather....where the solar panels keep on working...
@@dicktaug4773 Power output from solar panels drops over time so systems have to have extra capacity to allow for this, I'm not an expert just reiterating what a number of posts have said so you need to confirm but the posts seemed genuine.
Hydro turbines NEVER exceed 16% efficiency with accelerated mass losses due to rapid exit of water mass. To difficult for human engineers to figure out apparently ...
Good that the narration clarifies that this source of energy is cheaper than “off-grid” solar. Most people just notice headlines though. Yay misinformation. 🙄
This is very interesting, but there's not any logical claim being cheaper than off-grid solar, it's two totally different sources of energy. Using both is obviously the best solution since you can't always count on the source being stable.
“Genius Micro Turbine Halves Cost of Energy”. So in modern day corporate America terminology: “Energy companies charge double so they make more profit off of new technologies”
I imagine type of fish matters a lot for the fish pass through part. In the video it looked like they were testing it with an eel. Around here it would be salmon. Is the general idea no dams? I am assuming the fish pass through is only in direction of water flow. So around here, salmon returning to spawn (going upstream) would need a way around. Doable if no dam. Still, I like the intent.
Good points - and I imagine that a few decent sized tree branches would jam the works in no time. Hydro is great, for those blessed with nearby watercourses, but it won't solve the looming energy crisis.
@@winniewotsit4452 But nothing will fully solve the energy crisis, but, many projects can do their part by cleaning up the energy in certain areas, so its still is a win, cause when you add all those tiny parts, it becomes a massive help to the environment
This type of hydroturbine was in use since the mid-1980s. A separate downstream fish passage was in use. Hydro dam are expensive and time consuming to install. Electrical distribution is expensive. Business wants electricity during the day, consumer in the evening. River flow determines the quantity of energy available.
Keep up the good work we all need more water power tidal aswell as river what ever happened too wind Mills that's on the river too grind flower in the 19th century even before that
I really like this new hydro turbine. I hope we start implementing it all over and getting rid of old river dams. {I truly believe, The more our surroundings flourish, the more we all flourish.} With how bad I've been seeing "water level/droughts" in the Western America lately. I really hope we not only reintroduce Beavers all over to influence more water collection to important area's that we can use to supply crops, deal with forest fires. Instead of running our water straight back out to the sea or blocking the rivers natural process for the ecosystem to thrive. We've really messed up natural waterways from poorly designed hydroelectric projects. Before we knew how much negative impact they have on our Ecosystem's biodiversity, water oxygen levels, algae blooms, nutrient flow from inland location's to off shore location's. In some areas like where I live in NW Oregon, rivers are a direct connection from the ocean to the inland ecosystems. Keeping the rivers free is how we keep those ecosystems flourishing which directly connects to our qualities of Life. Our natural waterways are crucial aspects of the entire overall health of every aspect of our environment and anything that connects to that environment. In Oregon, we had some of the best Salmon runs on the planet and lush inland forests, wetland ecosystems, beaver's that created special habitats that held extra water/fire safety and all that got totally flipped upside down from all the hydro dams they built in the early 1900s, and many other practices we once commonly did. Before we knew or understood the negative effects and outcomes that comes from altering them into man made waterways. So I really hope to see tons of projects that are working on rewilding areas for the sole purpose of reestablishing ecosystem's that once flourished. Because Humans inherently do better when their environment is doing better. It provides a ton of benefit to it's people and to the quality of Life as a whole for not just humans but the entire ecosystem around you which will definitely have positive impacts to so many layers to people's life's and your community as a whole. ~~~~~~~~~~~~~~~~ This is why we need to invest in modern advanced nuclear energy options. Small form reactors, LFTRs, Thorium Reactors, liquid reactors. Utilizing our advanced modern technology, engineering, material science, safety measures understandings and designs, computer technology, robotics, It will really allow any nation to be pretty much be energy independent. Less reliant on fossil fuels. They'll have efficient, stable electrical grids and the rest of the grid could experiment with alternative power sources, etc. We need to heal from the trauma of our past and see that it came solely from Us not understanding what we were doing, not have advanced enough technology, material science, engineering, safety measures, understanding of how to go about everything, etc. This source of energy will greatly help the world improve towards the future and lowering emissions more than anything else could while having a very stable electrical grid system. Currently we have alternative energy options but the majority of our grid is powered off of fossil fuels and emission producing sources of energy. We will be so much better going forward commiting to modern advanced nuclear energy options. ~~~~~~~~~~~~~~~~~
Here in India, the dams save water in the summer so that some electricity can be produced even when there is less rain. But when the rain comes, the dam is full and the water released and all low lying areas are flooded. When the water velocity is less, the river dumps silt and the bed fills up fast. We need a solution that is people friendly.
Nuclear is horrible in so many ways you don't understand. Dams create wonderful ecosystems and the lowest cost/most reliable energy source available period.
@Ben McReynolds My question would be If it works in a river, why not a tidal estuary? Or offshore? . Nuclear? More like Unclear. . Nuclear costs 3 times the amount for 10-15% less energy compared to offshore wind. It takes double the time to construct. The energy it produces is 2.5 times the strike price. (Data from actual projects being completed very soon) . You could build double the wind project size, with *a lot* of storage, for lees money. . As for the SMRs. 1) They're not ready. 2) "Estimated" costs *will* overrun. 3) r Being "small" means you need many more, so the "system" (network) isn't faster to build. . By the time prototypes are produced (2025-27?) Tested (2-5 years?) Production ready (2 years?) And a complete network is built (who knows how long??) It's going to be at least 2040 before any meaningful energy is on line. That's too long.
Please don't forget that dams have a lifetime, when they silt up. Expensive to fix, which may require stopping or rerouting the water upstream for a year.
@@rogerstarkey5390 although that might soon be a wash since they have discovered a way to park CO2 into the cement permanently (to be seen ten years later if it stays)
1:26 Hydraulic head is measured in distance because it is a measurment of the difference in height between the surface of the water at one point and some other lower point, not a measurment of pressure. Pressure is however proportional to the depth of the water, which in the case of the turbine will be its hydraulic head. I just thought saying "hydraulic head (...) represents pressure" was a little imprecise.
Hydraulic head isn't a measurement of length, it's a measurement of height as a proxy for massless potential energy or potential energy per unit mass. The formula for potential energy (abbreviated as PE) is mgh where m is the mass, g is gravity and h is height, so if you want to calculate the PE per unit mass then the formula is gh, and since g is a constant the PE per unit mass is directly proportional to the height.
Think how much electricity Niagara Falls could generate with these instead of the existing turbines! A large portion of the water is diverted to make power, so only a fraction of its true power is seen. The river can actually be shut off. (Oh, the things you learn when you go to the museums and the tours on either side!)
That's all fine and good but 1: where is the water supply coming from and 2: what will you do in the winter when the water freezes over ? At least you can brush the snow off the solar panels or get a solar generator and charge it by plugging it into a wall outlet , i have 2 solar generators and i unplugged them 2 years ago and the li-ion battery is still at full charge
Yeah we all have river to put a trubine. And allwe have river wich have enought water flow to generate electricity. And after that how frendly is with aquatic life? Both technologie have pro and contra and most be mixed and used when it can be with regulation and all that stuffs.
This is just the same thing over an over again. I have seen and heard about dozens of companies and their projects to provide power with turbines. Nothing has changed in years.
Having a decentralized hydropower source would be ideal for the smaller, more isolated communities without the environmental damage and quicker access to electric power since they wouldn't have to wait for an expensive and vulnerable power grid network to be expanded from a central source.
just diverting fish to a 5% outlet downstream n keeping v efficient turbines for the fish free water is a lot more cost effective process. this filter will also keeps the blades safe from harder debris like logs wood stones etc.
What about sewer lines as well. I remember seeing something like this being installed in the Vancouver, BC area as a test project. Not sure what has come of it.
its not driving water, its being driven. its only extracting so much energy from the water, only achieving a pressure drop of so much. to try for a higher pressure gradient would simply stop water from flowing. basic principle... slow water down to half its velocity/reduce pressure by half. same thing. not enough pressure change for cavitation. the whole idea of a turbine is to extract energy as efficiently as possible. cavitation isnt efficient. for it to cavitate would require it be powered, driven, like a pump.
cavitation can take place only when the flow (rate) is high or the turbine speed is high. Modern water turbines are slow speed devices. I do not see cavitation as a serious problem
Toroidal propellers: Sharrow Marine has been getting frankly spectacular results from boat propellers that use toroidal loops instead of standard blades. After several years of development, the company has now tested its props against hundreds of standard propellers, and the difference is incredible. Sharrow's props simply don't create tip vortices - a major source of energy loss and a surprisingly large component in the overall noise of an outboard engine. th-cam.com/video/QNCbnntCU2k/w-d-xo.html
Thanks! It seems they need to operate within a certain rpm range for maximum performance advantage, and there's still the fish passage question, but very interesting.
Perfect. 4 pieces of a perfect energy grid : - this microhydro turbine - a reservoir - store energy as water in the reservoir - grow algae in the reservoir for biofuel
@@rogerstarkey5390 depends. The development of it has been trying to maximize fuel production per acre, which means using pressurized tubes. That seems like a dead end, imo. But I see no reason why a low energy version wouldn't work - it's just concentrating sunlight into something dense enough to harvest.
I would absolutely love a tiny turbine system for my rural property in Northern Alberta! We have an artesian well that runs into a little creek. Not only that Alberta currently has a program would buy back any surplus energy we'd create. I wonder what their smallest turbine would cost?
Theres a guy on youtube who does micro hydro turbines. All you need is enough water and slope to spin it. Ive seen a few where they put out enough to beat solar and definitely beat it price wise
@@fajile5109 LOL. My dude. Micro hydro is obviously by far better than solar or wind... if you have physical and legal access to a creek/stream with sufficient flow and head. In reality, very few people have such access.

South Africa needs these. Currently 11 out of 24 hours there is no electricity.
Maintenance, is always he maintenance that tips these project up. I remember the the wells for Africa project. They couldn't even look after a simple hand operated well pump. Some of them ended up fighting over who operated the well. Although they will be good for remote areas where there is sufficient infrastructure to repair and maintain them.
It happens everywhere, hope it ends up in peace and restoration of operations?❤, gopidas is a veteran of many such failure and recepiient of dusappointments

I've just come across your channel and subscribed to it, of course. Keep doing good job. With love from Poland
Awesome presentation, I’m glad I found this channel 😊
Interesting, well presented and explained in a way that a layman such as myself can understand. I look forward to watching your other videos 👍
Yes details aimed at layman.
exactly :)
Very interesting content. Your channel seems like it could become the B1M for energy engineering.
I don't see how any one could be against this idea brilliant.
Likely because it's mostly bullshit.
Picture this: Hydro dams and turbines have been around the block for a LONG time. Now, an amazing genius new cool idea pops up that nobody has ever thought of before!
What's the idea you ask? Slightly differently shaped turbine blades in a smaller form factor!
Do you still believe that this "new amazing cool genius idea" is something new and revolutionary? It's definitely been done before. It definitely already exists and if there aren't hundreds of similar versions of this out there in the wild already, then there's probably a good reason behind it.
Spoiler: They do exist, but they require so much maintenance that they're an awful investment. Water clogs and corrodes anything it touches over time.
I'm not clear on what makes this turbine "genius". It seems almost identical to other turbines out there for smaller installs. The video comes across like advertising for Natel Energy given the number of times they are mentioned.
We were told that energy would be come super cheap with wind turbines. In the UK you can’t get moving for wind turbines yet energy prices are at an all time high?
Bullshit.
the tech is here and has been for a few years now . we need to at least start the work to transform to renewables. we all need to put pressure on the ones who are in authority to get this going! And it needs to be now!!
Just found the channel so happy to have found some quality content
hopefully these can get installed in regions around the world for cheap energy from local watersheds. hopefully around middle america harnessing the rocky mountain watershed hydroelectricity
I just found this channel and Im loving every single video
I love this turbine, is what we all wanted free energy, freedom from government, free money, and environment is happy to have it!
So long as you own the river bed & flow and don't need an environmental permit for the construction in your country?
You deserve a lot more subscribers.
You'll still have to screen it... To keep mammals and logs out of it.
This is a great point, but the big grids needed to stop large logs and mammals are much easier, cheaper, and slow water less than fish screens - I should have mentioned that!
@@ZirothTech This would make a good topic for a future video.
The answer that these companies overlook is using bladeless generators inside sewage pipes. People are constantly creating waste, and yet very little (basically none) of that energy is recouped. Waste products are sometimes harvested for gases, or turned into fertilizers, but the kinetic energy created by transmission from the home to the treatment site is never collected (if at all). There's tremendous hydro-electric potential if only waste were managed better.
Gonna be a million sub channel in 2 years or less, keep it up!
Nice technology, hopefully these Hydro Turbine is in the future for us.
Great video.. very well presented! ❤
I am not a pro when it comes to HE turbines, but I showed this to a friend who was an electrical engineer in charge of all regional operations for GE. He was a german old-school pragmatic SOB. He categorically disagrees that this is possible, based on math and physics of all previously designed HE turbines. Any thoughts?
You’d think these would be used inline of water tower outlets that feed cities, you could put 50 inline.
You could downsize it for in home use on the water in-line connection.
They could connect to heating elements to heat sand batteries to heat the house and or hot water.
There's one giant problem with your solution: Every unit would drop the delivered pressure.
2nd Law of Thermodynamics: There is no free lunch.
@@Screw_This I´m wondering what difference big wind farms do to the enviroment, by taking kinetic energy of wind. It must have some effects, but there is almost no talk about it in mainstrem.
So, what's the cost of the whole system?
Misses the effect mollusks will have. Shields to protect fish will be the perfect place for them to settle which means regular maintenance. So what is the solution offered … likely expensive replacements as maintenance will be abandoned.
Only effective as long as the water flows.
And reservoirs and rivers have a tendency to dry up and reduce the flow rate in hot weather....where the solar panels keep on working...
Nothing that deals with water and moving parts is going to be cheaper than basically a static plane of glass.
Depends on how much the power output is, really.
Especially if your solar panel is free, and never wears out.
@@dicktaug4773 Power output from solar panels drops over time so systems have to have extra capacity to allow for this, I'm not an expert just reiterating what a number of posts have said so you need to confirm but the posts seemed genuine.
except solar panels arent just glass and have some not so cheap and not as durable materials in them
Hydro turbines NEVER exceed 16% efficiency with accelerated mass losses due to rapid exit of water mass. To difficult for human engineers to figure out apparently ...
Good that the narration clarifies that this source of energy is cheaper than “off-grid” solar. Most people just notice headlines though. Yay misinformation. 🙄
This is very interesting, but there's not any logical claim being cheaper than off-grid solar, it's two totally different sources of energy. Using both is obviously the best solution since you can't always count on the source being stable.
This seems like a winner really.
Perfectly explained. Thank you.
"Ticked and subscribed, all", that video was a quality construction and extremely informative., Brilliant stuff well done :)
“Genius Micro Turbine Halves Cost of Energy”.
So in modern day corporate America terminology:
“Energy companies charge double so they make more profit off of new technologies”
I imagine type of fish matters a lot for the fish pass through part. In the video it looked like they were testing it with an eel. Around here it would be salmon. Is the general idea no dams? I am assuming the fish pass through is only in direction of water flow. So around here, salmon returning to spawn (going upstream) would need a way around. Doable if no dam. Still, I like the intent.
Good points - and I imagine that a few decent sized tree branches would jam the works in no time. Hydro is great, for those blessed with nearby watercourses, but it won't solve the looming energy crisis.
5m of head is nothing. That is a typical drop for existing rapids on most rivers.
Salmon jump a metre regularly.
@@winniewotsit4452
So use less energy.
The comment in the article summed it up.
One US home consumes the same as 20 African homes..
"Use less stuff"
@@winniewotsit4452 But nothing will fully solve the energy crisis, but, many projects can do their part by cleaning up the energy in certain areas, so its still is a win, cause when you add all those tiny parts, it becomes a massive help to the environment
This type of hydroturbine was in use since the mid-1980s.
A separate downstream fish passage was in use.
Hydro dam are expensive and time consuming to install.
Electrical distribution is expensive.
Business wants electricity during the day, consumer in the evening. River flow determines the quantity of energy available.
Keep up the good work we all need more water power tidal aswell as river what ever happened too wind Mills that's on the river too grind flower in the 19th century even before that
The blades need cleaning and replacing...no small job in itself.
I really like this new hydro turbine. I hope we start implementing it all over and getting rid of old river dams. {I truly believe, The more our surroundings flourish, the more we all flourish.} With how bad I've been seeing "water level/droughts" in the Western America lately. I really hope we not only reintroduce Beavers all over to influence more water collection to important area's that we can use to supply crops, deal with forest fires. Instead of running our water straight back out to the sea or blocking the rivers natural process for the ecosystem to thrive.
We've really messed up natural waterways from poorly designed hydroelectric projects. Before we knew how much negative impact they have on our Ecosystem's biodiversity, water oxygen levels, algae blooms, nutrient flow from inland location's to off shore location's. In some areas like where I live in NW Oregon, rivers are a direct connection from the ocean to the inland ecosystems. Keeping the rivers free is how we keep those ecosystems flourishing which directly connects to our qualities of Life. Our natural waterways are crucial aspects of the entire overall health of every aspect of our environment and anything that connects to that environment. In Oregon, we had some of the best Salmon runs on the planet and lush inland forests, wetland ecosystems, beaver's that created special habitats that held extra water/fire safety and all that got totally flipped upside down from all the hydro dams they built in the early 1900s, and many other practices we once commonly did. Before we knew or understood the negative effects and outcomes that comes from altering them into man made waterways. So I really hope to see tons of projects that are working on rewilding areas for the sole purpose of reestablishing ecosystem's that once flourished. Because Humans inherently do better when their environment is doing better. It provides a ton of benefit to it's people and to the quality of Life as a whole for not just humans but the entire ecosystem around you which will definitely have positive impacts to so many layers to people's life's and your community as a whole.

This is why we need to invest in modern advanced nuclear energy options. Small form reactors, LFTRs, Thorium Reactors, liquid reactors. Utilizing our advanced modern technology, engineering, material science, safety measures understandings and designs, computer technology, robotics, It will really allow any nation to be pretty much be energy independent. Less reliant on fossil fuels. They'll have efficient, stable electrical grids and the rest of the grid could experiment with alternative power sources, etc.
We need to heal from the trauma of our past and see that it came solely from Us not understanding what we were doing, not have advanced enough technology, material science, engineering, safety measures, understanding of how to go about everything, etc. This source of energy will greatly help the world improve towards the future and lowering emissions more than anything else could while having a very stable electrical grid system. Currently we have alternative energy options but the majority of our grid is powered off of fossil fuels and emission producing sources of energy. We will be so much better going forward commiting to modern advanced nuclear energy options.

Here in India, the dams save water in the summer so that some electricity can be produced even when there is less rain. But when the rain comes, the dam is full and the water released and all low lying areas are flooded. When the water velocity is less, the river dumps silt and the bed fills up fast. We need a solution that is people friendly.
Nuclear is horrible in so many ways you don't understand. Dams create wonderful ecosystems and the lowest cost/most reliable energy source available period.
@Ben McReynolds
My question would be
If it works in a river, why not a tidal estuary? Or offshore?
.
Nuclear? More like Unclear.
.
Nuclear costs 3 times the amount for 10-15% less energy compared to offshore wind.
It takes double the time to construct.
The energy it produces is 2.5 times the strike price.
(Data from actual projects being completed very soon)
.
You could build double the wind project size, with *a lot* of storage, for lees money.
.
As for the SMRs.
1) They're not ready.
2) "Estimated" costs *will* overrun.
3) r
Being "small" means you need many more, so the "system" (network) isn't faster to build.
.
By the time prototypes are produced (2025-27?)
Tested (2-5 years?)
Production ready (2 years?)
And a complete network is built (who knows how long??)
It's going to be at least 2040 before any meaningful energy is on line.
That's too long.
Please don't forget that dams have a lifetime, when they silt up. Expensive to fix, which may require stopping or rerouting the water upstream for a year.
Not to mention the huge carbon deficit in concrete and the fossil generation which remains on line during the construction.
@@rogerstarkey5390 although that might soon be a wash since they have discovered a way to park CO2 into the cement permanently (to be seen ten years later if it stays)
1:26 Hydraulic head is measured in distance because it is a measurment of the difference in height between the surface of the water at one point and some other lower point, not a measurment of pressure.
Pressure is however proportional to the depth of the water, which in the case of the turbine will be its hydraulic head. I just thought saying "hydraulic head (...) represents pressure" was a little imprecise.
In Khyber Pukhtunkhwa Province of Pakistan we need this turbine so much. It can be installed on Swat river in various places
Hydraulic head isn't a measurement of length, it's a measurement of height as a proxy for massless potential energy or potential energy per unit mass. The formula for potential energy (abbreviated as PE) is mgh where m is the mass, g is gravity and h is height, so if you want to calculate the PE per unit mass then the formula is gh, and since g is a constant the PE per unit mass is directly proportional to the height.
good work covering this...something that could be used in areas of the Philippines
This sounds good for new builds of a housing estate in the water mains as they are under pressure
Wow thanks for a great vid, which the explanation of the turbine function and new blade tech.
Think how much electricity Niagara Falls could generate with these instead of the existing turbines!
A large portion of the water is diverted to make power, so only a fraction of its true power is seen. The river can actually be shut off. (Oh, the things you learn when you go to the museums and the tours on either side!)
Oh wow, a small dam! Who'd have thought?
Nothing beats the Francis turbine.
Damn you are smart. Keep making videos.
This definitely has potential.
Literally!
That's all fine and good but 1: where is the water supply coming from and 2: what will you do in the winter when the water freezes over ? At least you can brush the snow off the solar panels or get a solar generator and charge it by plugging it into a wall outlet , i have 2 solar generators and i unplugged them 2 years ago and the li-ion battery is still at full charge
I don't think the rivers freeze in central Africa.
only some rivers ever fully freeze and in EU rivers, the winter flow is usually a lot higher than summer flow.
and yeah, Congo doesn't have freezing temperatures neither
Yeah we all have river to put a trubine. And allwe have river wich have enought water flow to generate electricity. And after that how frendly is with aquatic life?
Both technologie have pro and contra and most be mixed and used when it can be with regulation and all that stuffs.
This is just the same thing over an over again. I have seen and heard about dozens of companies and their projects to provide power with turbines. Nothing has changed in years.
Having a decentralized hydropower source would be ideal for the smaller, more isolated communities without the environmental damage and quicker access to electric power since they wouldn't have to wait for an expensive and vulnerable power grid network to be expanded from a central source.
just diverting fish to a 5% outlet downstream n keeping v efficient turbines for the fish free water is a lot more cost effective process. this filter will also keeps the blades safe from harder debris like logs wood stones etc.
The GOV in Virginia USA uses KES to pump the water back up to two small lakes, making it the most efficient hydro-electric system in existence...
They fuck the rivers up, disrupts the flow of water, leeches chemicals, chews up fish (yes they do), and destroys kayaking opportunities
It has a great efishiency 😊
is the 2.5 meter model the largest model for optimal production? Is this model suitable for offshore devices? Thanks
Could these units be combined with inter City water lines, so as cities move water between each other they also generate electricity?
What about sewer lines as well. I remember seeing something like this being installed in the Vancouver, BC area as a test project. Not sure what has come of it.
Can these be used on seabeds or held in open sea?
Won't cavitation cause wear on the blades?
Absolutely, it’s unavoidable
its not driving water, its being driven. its only extracting so much energy from the water, only achieving a pressure drop of so much. to try for a higher pressure gradient would simply stop water from flowing. basic principle... slow water down to half its velocity/reduce pressure by half. same thing.
not enough pressure change for cavitation.
the whole idea of a turbine is to extract energy as efficiently as possible. cavitation isnt efficient. for it to cavitate would require it be powered, driven, like a pump.
cavitation can take place only when the flow (rate) is high or the turbine speed is high. Modern water turbines are slow speed devices. I do not see cavitation as a serious problem
Toroidal propellers: Sharrow Marine has been getting frankly spectacular results from boat propellers that use toroidal loops instead of standard blades. After several years of development, the company has now tested its props against hundreds of standard propellers, and the difference is incredible. Sharrow's props simply don't create tip vortices - a major source of energy loss and a surprisingly large component in the overall noise of an outboard engine. th-cam.com/video/QNCbnntCU2k/w-d-xo.html
Wow thanks for sharing
Thanks! It seems they need to operate within a certain rpm range for maximum performance advantage, and there's still the fish passage question, but very interesting.
Thank you. That was interesting, and thankfully you did not include any noticeable and loud and inappropriate off-putting music over voice.
I liked your micro hydro turbine concept. I also just subscribed
I'm interested with this innovation of turbine. Is there any way we can purchase it? i live in a remote area here in the Philippines.
Great video as always! Super clear
Not only it doesn't kill the fish, it gives them a hell of a thrill!
Interesting. I was just wondering how it would work on ocean tides?
Great for a few months, then corrosion would destroy it. Working with salt water can really push up your costs
@@talltroll7092 Shame England is surrounded in sea water.
Perfect. 4 pieces of a perfect energy grid :
- this microhydro turbine
- a reservoir
- store energy as water in the reservoir
- grow algae in the reservoir for biofuel
But if I recall correctly, biofuel is notoriously energy inye so r to produce.
It's another hydrogen.
Just use the electricity.
@@rogerstarkey5390 depends. The development of it has been trying to maximize fuel production per acre, which means using pressurized tubes. That seems like a dead end, imo. But I see no reason why a low energy version wouldn't work - it's just concentrating sunlight into something dense enough to harvest.
Put it to work ASAP...! anything helps ! Just do it ..!
Really interesting video thumbs 👍 cheer’s 😊
Do a video on the hivawt wind turbine only certified micro vawt in USA. Turbine guy youtube channel has them
Well done. Keep them coming. Subscribed.
I would absolutely love a tiny turbine system for my rural property in Northern Alberta! We have an artesian well that runs into a little creek. Not only that Alberta currently has a program would buy back any surplus energy we'd create. I wonder what their smallest turbine would cost?
See "diy pelton turbine" th-cam.com/users/results?search_query=diy+pelton+turbine
Theres a guy on youtube who does micro hydro turbines. All you need is enough water and slope to spin it. Ive seen a few where they put out enough to beat solar and definitely beat it price wise
@@fajile5109 LOL. My dude. Micro hydro is obviously by far better than solar or wind... if you have physical and legal access to a creek/stream with sufficient flow and head. In reality, very few people have such access.
@@yekutielbenheshel354 That is not an issue in northern Canada.
Sounds great! How flood resistant is it? DRC rivers can have epic forces in some places
