Harvesting the Wave Energy: The Function of Wells Turbine
Вставка
- Опубліковано 24 жов 2019
- In this episode, we explain the function of Wells Turbine. This turbine is one possible power take-off for the oscillating water column concept of harnessing the wave energy. In our movie about the "Limpet" wave power plant, this turbine is shown, but not explained. Several viewers couldn't understand the function of this turbine. Some of them even claim that this turbine couldn't produce any energy. This is the reason why we created this movie. We are not affiliated with any company which is producing this type of turbine. This movie is also not made in a commission of anybody. Its sole purpose is to explain the function of the Wells Turbine. Maybe, watching this movie, you will get another idea for the solution of harvesting wave energy and help to produce sustainable energy. We just spread the ideas to keep our planet green.

Damn all y’all so negative, y’all should realize to achieve the dream of green energy if it gonna take numerous different types of energy production. This video didn’t suggest this is the best option it just simply presented another tool that can be used.
Lets throw in everything we can. Nuclear sources still have waste issues but we can always decommision as renewables come on line.

@@redfox435cat What? nuclear is 100% safe? You gotta be joking!
One of the best system so far simpler cheap an easy to install as well as easy to operate. We should see much more of that hopefully soon.
Brilliantly explained given the time constraint in this video. Helpful where it needed to be.
Absolutely amazing. I love this concept. Thank you for uploading this video.
Certainly seems an impressive output for something so simple and I like how easy it is to maintain, especially compared to wind turbines. A bit of camouflage on the outside with rocks and sculpting and you'd not even know it was there. Built well it would probably last for at least a century.
looking forward to your next video in 2029
0:45 I gave you a FAT "thumb UP" for explaining that! :-)
I can´t image how it worked. At a normal fan the blades are connected ca. 45°.
Greetings from germany
@Albrecht8000: Thank you SOOOOO much for your kind comment. 👍 This is why we made this movie! Greetings to Germany 😎
Que buena idea, gracias a los genios que la concibieron!! 👍🏽👍🏽👍🏽👍🏽
Thank you very much for this presentation.
Portugal has been using wave,and swell power for years.
@j a Thank you for your comment. The researchers and developers from Portugal (Tecnico Lisboa) are very active in the development of a novel radial self-rectifying impulse air turbine for use in Wave Energy Converters.
The Mutriku wave power plant is also a place where researchers can develop and improve turbines, increase efficiency and reliability. This research project is called OPERA and has received funding from the European Union’s Horizon 2020 research and innovation program. opera-h2020.eu/
Oddly simple... impressive.
great video guys, the wells turbine works like magic lol
This is absolutely amazing and it will certainly help to reduce emissions into the atmosphere
brilliant !!
Wunderbar. Awesome 👍
Fantastic idea 👍
How beautiful..
Thank You.
Been dying to know how the turbine works, thanks.
@Terry Tytula : 🤔 Looks like this explainer video is not good enough.
Fantastic technology .. Powerful energy source for turbines
Pretty cool
superb !!
So simple yet so genius...
I like this idea or invention to help our country to make the power consumption be cheaper...
16 to power 250 households... That's a little below 16 households per turbine. A standalone CANDU 650 type reactor can power around 390 000 households. You could make a thousand turbines like that, with all that concrete and still not come close. Not to mention that you can make one CANDU plant with 8 units and the number of households it can power is measured in several millions.
But the nuclear waste can be a problem, and the maintenance of it too!
along with the safety hazards of any plant...
this one can be used on islands and other places by the shore
@@ShelbyRestorations By such a difference in energy production and efficiency the risk is negligible, especially considering how low it is with modern solutions. Also, not every country has islands or a shore and those with shores have limited space, so it'd be a huge waste of space and materials for the production, when you could just build 1 nuclear plant. We are talking about 1 plant vs hundreds of thousands of turbines. It's just not a viable replacement, physically, economically and logically. Recycling nuclear waste, like in France, is more viable in this scenario. As it stands, nuclear power is the most efficient clean power we know.
Yes, This is only good for small villages or private use.
No shit sherlock. You're comparing this to a nuclear powerplant. What r u gonna do with all that nuclear waste then?? Throw it in the ocean?? Bury it?? Eat it??
@@Hikari_Sakurai that's my point, nuclear energy isn't the best right now, as waste disposal is a huge problem!
Great.
nice idea
Amazing!
Very nice 3d renders! Very instructive and inspiring video for helping the world and ourselves.
What about a wind power video?
@Vlad Ghelu: Thank you very much for your kind words. We think that there are already a lot of videos which explain wind power very well.
So simple!
Must try this
Of course, although not optimised for it most turbines would turn in the same direction if the gas flow comes from either side.
This method seems to offer the advantage that it could be integrated into sea walls that are in place primarily for protection thus defraying overall costs for the turbines and the sea wall. Also it could be integrated into ground built offshore wind turbines. It also has the advantage that its moving parts are largely clear of the corrosive effects of salt water and are accessible above water.
@Giles Pargiter : Thank you for your comment. Yes, you are right. There is the wave power plant in Mutriku/Spain which is built into the wave breaker - which is already there to protect the harbor.
One video after 10 years. Woah!
@Arun G : Thank you for your comment. We are not the producer or vendor of this technology. We have been working on this movie for more than 5 months. Nobody paid us for doing it - it is just our small contribution to spread the knowledge about the possible wave energy harvesting.
This should be implemented everywhere around the world. Talk about solving energy issues.
@Eugene Stoner sorry..where it "Can" be implemented....
@Eugene Stoner personally I like Einstein's idea of a small nuclear power plant in the basement of every home powering everything from heat to your mode of transportation. Unfortunately to dangerous and the waste that it would produce would be a disaster
I fantasise about these sort of things giving power on the small Pacific islands etc where for many diesel is the only electrical energy source,
One only need to visit the blow holes to see the incredible energy available
@Nathan : Yes Nathan you are right, if the waves are strong enough 🌊
Tanks brother
Proving that simple can be better 👍
This is good, but how do you work out how much room is required to generate the ideal amount of wind and what is the ideal size of the turbine. Basically how do you make a very effecient project. I would love to get involved
@Islam future: Thank you very much for your comment. We are not the producer or vendor for this technology. We made this movie to introduce this technology to a broad audience. We are so happy that this movie inspired you to dig deeper into this concept.
Please check out this site: opera-h2020.eu/
Universities from Portugal and Ireland are also involved in this project, so I assume there are possibilities to study.
Better put a float inside the column chamber to actuate the generator either mechanically or hydraulically. It will be more efficient.
Later, you may add more floats just outside the chamber to increase the power output. Even more efficient.
Wouldn't adding a float slow down the water coming in? And slowing down the water would decrease the velocity of the air passing through the turbine. It would be interesting to see what the trade-off on power would be.
My idea is to not use air for moving the generator. The float can move a mechanism directly, or can move a hydraulic pump. Then this mechanism or the hydraulic pressure moves the generator. That way the brief pauses when transitioning between positive and negative pressure are eliminated.
Optron Cordian I’m not sure that the amount of work you can get from a float is greater than work from a turbine. Like I said it would be interesting to compare the two.
I am curious too...
The design is novel, in that the shaft always turns in the same direction. In doing so, the acute attack angle, causes the turbine to "stall", and often in need of being electrically started. Suited only for large surf conditions. If it were effective, it would be commonplace. There are better methods, of utilizing the OWC air flow. The video is done well, and clearly explained.
@ Steve Clayton: Thank you for your comment, sir. At this site in Mutriku Power Plant, the new bi-radial turbine is tested. It is great, that you are working on improvements!
@@IdeasfortheGreenPlanet There is nearly a 50% loss of kinetic energy. It will turn only as fast as the air is pushing, and therefore will simply pass through those voids in between the blades. As you enlarge the unit, the voids grow larger, in relationship to the blades surface area. Self defeating. I am surprised at how much personal energy has been devoted to this design. I have a much better turbine design, simple and less expensive to build. Works with low pressures.
@@steveclayton5692 do you have a video of your design?
@@seventyseven.77 Yes I have several videos, and making new ones. My Patent application is still pending. The video will show it working in a Bi-Directional manner, though will not reveal how it works. I am currently building larger units, to be tested offshore, PacWave (OSU) Oregon USA. Under
the same conditions, the Well's Turbine will not spin. It requires a large volume of fast air to operate.
if you do taller air towers, it might provide more electricty per square space used?
สุดยอดมากครับ
Hay quá
This is so important to us that we could even bother using a real voice.
@percival23: Sorry for your inconvenience. This movie is solely for educational purposes. We want to spread awareness for this kind of harvesting wave energy. We are not the producer nor the vendor of this technology or components. We made this movie at our costs. It took us months for its creation, especially water simulation.
Had the same idea in high school only it involved a giant float and gear.
Same I had the idea in 7th grade I'm in 8th now...
I hate it that every time I come up with a genius idea it was already invented 🤦😭
What about salt gathering on it ?
Very good technology
What do you understad yar......
...a series of such turbines all 'insync' on level.uniform shoreline...add solar panels as well maybe a combo will help
Didnt knew Rav had the voice for this.
Now this is big brain time
what is the type of shaft??
好聰明
lol, this is just a vertical version of the upload a decade ago
If it can be animated, it can be sold. Seems like a very expensive way to generate fairly small amounts of electricity or we would be seeing them everywhere by now. They built 2 (two) 500 kw plants in Europe at least a decade ago as noted in the vid.
@SunriseLAW: In the year 2011, the Mutriku (Spain) Breakwater Wave Plant was inaugurated. It is the world's first breakwater wave power plant with a multiple turbine arrangement. The plant has a capacity of 296 kW from 16 turbo generator sets. This technology is evolving. There is a lot of R&D on this site.
@@IdeasfortheGreenPlanet Thank you. I contend that the majority of such projects are essentially scams. The biggest, worst environmental scam is "bio-fuels'... the alcohol in the gasoline. The most expensive scam is the "cap and trade of carbon credits" which OR, WA, CA, and NV got stuck with by their legislatures and causes much higher gas prices. Nothing but an attorney-fee fest. That is all MOST of the "green" initiatives are.
Often in the Summer in Southern California there are no waves. Tides remain consistent.
For harvesting the wave energy, the waves have to possess a lot of kinetic energy, which is not the fact everywhere globally.
One thing this presentation is missing is what size are the turbines, both physically and in kilowatts. Estimated price would be nice, but as these are prototype test units their current expenses have no relation to how much a proper wave power plant would eventually cost to build and operate.
Interesting, What if one installed a (modified) device like that on a displacement vessel.
It begins with gravity pulling the vessel downwards. While the vessel moving down, air is let into a cylinder that are open to the sea.
A wave moves the vessel upwards. The now trapped air makes energy by using a piston with a permanent magnet and a linear motor (alternator) to capture the energy.
@ Lars Hansen : Thank you for your comment. This sounds like Free floation Oscillating Water Column project: www.researchgate.net/publication/265857026_Challenges_and_lessons_learned_in_the_deployment_of_an_offshore_oscillating_water_column
I got the same Idea!!
@@IdeasfortheGreenPlanet Thanks for sharing brother^^
Good
How initial rotation of turbine blade is given please clarify
@ amitabh mishra : Thank you for your excellent question! The turbine needs the initial spin with an electric motor. In the movie, it is placed on the backside of the turbine.

Sir why you are not given other videos
Прииикольна
Everything move can we use to make energy. Right?
@Illham IDSA: Thank you for your question. Yes, you are right, everything that moves by itself without energy supply from the people could be used for energy generation. Go ahead, just do it!
Let's say you build the turbines one next to another on the Netherland's sea wall. How much power can you get from 1 kilometer long coast per year? In kWh. And what will be the cost.
@809Kocur Thank you for your comment. We are not the producer of a wave power plants or Wells turbine. The wave power plant in Mutriku, Spain is built into the breakwater. It is designed for 16 chambers with Wells turbine, 4.5 meters each => approx 80 meters. They are designed to produce 296 kW per hour. But you can't just scale up this data for 1km. It depends also on the energy of the waves in that area. More information: tethys.pnnl.gov/project-sites/mutriku-wave-power-plant
Can I take screenshots from this video with citating in my article?
Sure, but please cite the source! Thank you
A intermediate pressure storage chamber and continuous discharge to the turbine at a constant speed would be more practical.
Very noice
In my opinion this is the only practical solution for eco friendly & low cost energy problems
Only downside is that apparently they are very loud, especially with stormy waves.
@Ryan R: The researchers are working on a novel radial self-rectifying impulse air turbine for use in Wave Energy Converters which has a silent operation and the highest known efficiency amongst air turbines (over 70%).
@@IdeasfortheGreenPlanet sounds interesting. Have you got a link to a site please?
Yes
Hello, what software do you used?
@ Andy Widiyanto : Hi Andy, we use Autodesk Maya with Bifröst and Real Flow.
how do they install something like this?
i like the design. but to make it work requires installation which looks difficult.
I don't know what do you mean "installation looks difficult". The turbine is installed in the house above the hole. It is easily accessible.
@@IdeasfortheGreenPlanet
I was referring to the construction of the base house. Is it a prebuilt mold or is it built after the installation of this product.
I am basically talking about the casing structure around the turbine. Made from concrete I would assume.
@@IdeasfortheGreenPlanet
As I said, I like the idea of this turbine. It seems very efficient.
@52262, Thank you for your comment. According to the information we have from the construction of the Mutriku power plant, a concrete foundation was build in the water first. Then they stacked the prebuild mold, as you guessed. The wave power plant is a part of the breakwater. First, they planned the breakwater and then they decided to enhance it wave power plant.
@@IdeasfortheGreenPlanet
So is there one in use. I mean instead of the animation. Is there a real example of this running.
Wow. There are several wave powerplants in the world.
Yet all we see are CGI and photos of the facilities exteriors.
No real-life equipment or interiors of the power plants are shown.
That all looks suspicious.
@Denis Mus: You can see the wave energy plant in Mutriku on the Foto in the movie. It is built into the breakwater. This plant is providing households with electricity for years under real conditions. Unfortunately, we don't have copyrights to use the pictures from inside, but you can see the interior and also visit the plant. www.mutriku.eus/en/tourism/mutriku/olatu-planta
what software is this made with?
@Arshad Nizar : Autodesk Maya, Bifrost, RealFlow, Substance
This is a pretty cool how direction of air flow is irrelevant. You could make a more efficient wind generator functional in only one direction but you would need two. Double the price! You would also need something like a diaphragm to select generator based on direction of air flow. Price and complexity go up! Kind of reminds me of the movie Logan's Run where they used generators operated by the tide. With the decades of ocean studies, implementing these generators on a grand scale seems feasible. You probably to eliminate the cost and construction headaches of the concrete chamber by mounting the generator in a PVC tube and mounting the tube vertically.
Is there such an impeller for which direction of airflow is irrelevant?? I mean a single one (uni directional motion for the impeller without any dependence on flow of air )
The problem is the turbine takes time to slow down before it can change direction. Changing direction makes it highly inefficient. This system would work better in one direction with a heavy flywheel. Adopt the system used in turbo cars and use an air bypass valve. As the wave draws back and creates a vacuum, the valve can open bypassing the turbine allowing it to continue in the same direction while still generating power, the valve closes again as the wave comes back up pressurising the chamber and driving the turbine further.
@@musiclibrary894 The impeller they use in their demonstration will rotate the shaft in the same direction no matter which direction the air flows. That's why their design is simple and cost effective.
@@Cameron..... If your referring to the turbine in their demonstration, it only rotates in one direction. It doesn't matter if the air is flowing up or down the shaft. The continuous rotation in one direction as the air rushes in and gets drawn out of the chamber is possible using their simple/inexpensive impeller design.
@@michaeldvorak5556 yeah, could be alternating blades. I though they meant it didn't matter the direction the turbine rotated. A giant flap on the inside of the chamber would be pretty inexpensive and more simple that turbine blades anyway.
Seems somewhat inefficient. Changing blade profile and duct each separately. Intake on one side and exhaust on the other side with spring loaded dampers to close them off seems it would allow more efficiency.
Go ahead and make it then.
How come this isn't as popular as solar or wind? I mean it's over 2 decades since the 1st facility based on the other video that said something about a plant being operational since November 2000.
It costs a lot to build, frankly, looks ugly, uses up coast space, and has requirement of being built on a coast.
You can plop down billions of panels in deserts, billions of turbines in windy plains, but coast space is way more limited and not every country even has one.
Its questionable.. effieciency.. againts wind turbine.. actually waves produced by wind.. so if you already have strong wind maybe it more sense to use it in the first place? Project has some limited uses of course.. but nothing more.
Thanks for showing and explanation how it functions! Now it is very clear. Has some strong features.
But something is missing yet. Can we get in touch?
@Cor Graveland: Thank you for your comment. We are not the producer nor the vendor of this technology.
Better make it with polymer.. ocean moisture is hell on most material

а теперь шторм или полный штиль)
0:53 that's not how wing physics works. Most force gets created by the air that moves around the tip, not the air the hits the underside of the blade. That's a common misconception.
That's not a wing tho
Also a misconception is that Bernoulli interactions and the Coandă effect are responsible for generating lift on airfoils. They are not. The pressure differentials generated on and around an airfoil are approximate enough to Bernoulli that Bernoulli's formulas are used in designing aircraft, but Bernoulli forces contribute little to lift generation by way of an airfoil.
Airfoils utilize the vacuum generated on their top side to pull down and accelerate it downwards, and in so doing, the opposite reaction is lift: It's Newtonian. Airfoil equipped aircraft are essentially horizontal rockets, but much more efficient.
Airfoils are more efficient in sustaining flight because the majority of the energy utilized to maintain lift for airfoil equipped aircraft comes from gravity: 66% to 75%, or more.
after watch 10 years video, Voith version, but this more compact.
Muje spot ki zarort ha
When fins move freely 10 digree up and down....so it can provide more energy.
is electricity generation directly proportional to the speed of the displaced air? i.e.Faster the air more the electricity produced
Volgens mij een verhaal van prutsers.
Energie wordt niet in kW uitgedrukt maar in kWh .
De opbrengst zal dus wel uit de duim gezogen zijn.
@Ron Faber: Thank you for your comment. I am sorry that you ignore the fact that the power plant in Mutriku, Spain is built and working.
Is that a Blender animation?
No, this animation was made with Autodesk Maya - Bifrost.
Why don't they ever mention Portugal. 4 types of swell generators for years.
can you introduce some references used in this video?
This energy harvesting concept is used in the wave power plant in Mutriku, Basque Country in Spain.

Wells Turbine?
hello creator......after almost 11 yrs.
пиздато.
Airflow? Why not water flow? Is it possible?
Yes, it's called Tidal power
@leowulffan: The power plants on the rivers also use water flow. They have a different type of turbine, like the Pelton-Turbine or Francis-Turbine. These turbines are much more efficient than Wells-Turbine.
Does anyone think the canary islands can do this?
@ Nestor Abreu Jimenez: Thank you for your question.
(en.wikipedia.org/wiki/Wave_power#/media/File:World_wave_energy_resource_map.png) According to this map, it should be not enough ocean energy in the region of Canary Islands for harvesting the wave energy with this oscillating water column concept.
It needs initial start so human required not automatic less efficient with 16 turbines supplying only 250 house and useful in coastal areas.
All these people in the comment don't realize that you could have a continuous line of these on the coast. So it could generate a good amount of electricity
A continuous line of these along the coast would equate to mass destruction to coastal environments
@@neilmackinnon9158 using fossil fuels will cause the sea level to rise via global warming, that will mean that the coast will recede. Anyway.
@@mohammedkhan5344 I'm not disagreeing with that. But the installation of these along the entire coast would destroy some of the most productive and important ecosystems. Installing these systems in place of berms/walls would make sense.
@@neilmackinnon9158 that's your opinion, it's not proven fact, it could be built to accommodate the ecosystem. They will not build on a coral reef, even if they do, it could be built to house organasims and small fish and plant life. Eg transfer the ecosystem onto the build.
@Islam future @Neil MacKinnon
The oscillating water column principle can also be used on buoys, which are placed offshore. There is a project funded by EU called OPERA H2020. You can watch the movie about the open sea operating experience here: ua-cam.com/video/57T5yorqHSg/v-deo.html
