Harvesting the Wave Energy: The Function of Wells Turbine

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.

[dirkschneider]

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.

[Maebbie]

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°.

Brilliantly explained given the time constraint in this video. Helpful where it needed to be.

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.

[belalcantara]

I like this idea or invention to help our country to make the power consumption be cheaper...

[whitenas]

This should be implemented everywhere around the world. Talk about solving energy issues.

[terrytytula]

Been dying to know how the turbine works, thanks.

Portugal has been using wave, and swell power for years.

[unhooked]

This is absolutely amazing and it will certainly help to reduce emissions into the atmosphere

[Froggability]

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

[piotrklepinowski]

Absolutely amazing. I love this concept. Thank you for uploading this video.

[nacerben]

Thank you very much for this presentation.

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.

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.

[Hector-uutb]

Que buena idea, gracias a los genios que la concibieron!! 👍🏽👍🏽👍🏽👍🏽

[Gilespargiter]

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.

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.

Fantastic technology .. Powerful energy source for turbines
