Yes it is less expensive but above all more productive, with constant production all year round and all the time and almost "indestructible"! In short, it looks very much like "perfect" renewable energy!

Now I haven't found any power and cost figures yet! I just saw that the "limpet" has been running since 2000 and that an 18.5 kW turbine is in development?

Finally there are surely answers in these docs: http://www.wavegen.com/research_papers.htm

By cons it is strange that there is no patent ... since it apparently not yesterday ... :?:

Well, in France, the conservatoire du littoral actually buys a lot of things ...

Do not count on them to allow this kind of project ...

Perfect unless there is no wind, but the waves do not require much wind and nothing comes to harm the wave like the wind which recovers much more in height. :D

Really! so we are not the only ones to have fuckers ... : Evil:
Thank you for the answer! :D

Well, some sites will be more suitable than others, but I have rarely seen a sea of ​​oil near the coast!

In any case, the potential of this invention exceeds, in my humble opinion, all other renewable energies except solar concentrator and ETM ...

that is calculated that!

just multiply the modules, simple and inexpensive
low pollution, low noise and easily integrated into the landscape :D :D :D

Well yes but not obvious ...

The coast winds map is easy to find ... the wave strength / height map a little harder ... but good as the 2 are linked ...

If it is it is on the wavegen site ... must potash their .pdf http://www.wavegen.com/research_papers.htm

Hello ,

Uh yesterday tide of 114 in Brittany, so full moon, the biggest for thirty years seen for well 25 to 30 years, well guess what, sea of ​​oil petole calm calm. Just a breeze and a very beautiful beautiful sun .

the waves depend on the planetary alignments among others but also on the configuration of the bottoms, currents and kla direction and force of the wind, asked the surfer he manages the thing quite well and looked at windguru and you see that the waves according to the location there is not necessarily one.

I would retain more the idea already in application for quite a year in, england, where it is a water pump which is actuated by the movement of the sea, to fill a reservoir in height which empties it in a turbine to produce elec. , and there have removed the problems of turbine involving the variable speed of the wind turbine, a water turbine at a defined and fixed speed so to speak, therefore much simpler for the calculation of the electric generator part.

And if not I think that for waves it is like for the wind, each place has its own characteristics, take an area where the bottom rises suddenly, there will always be very big waves during tides, but it will be punctual and not general;), and when it’s general then on this lift in general it’s very very big waves;).

The idea is super good for certain places, I don't think there is a perfect solution but solutions adapted to the place, in the mountains the wind turbine is easier to implement than a tidal power plant : Mrgreen: .

see you

Thank you! Here are others on "VOITH" which is the German industrialist who apparently developed the turbine used by wavegen:

Thanks for the videos.
It looks like they're using a hydrostatic transmission to spin the turbine. In other words, according to what we see, only one stage of the wave would be exploited.

Too bad I don't understand German so I can confirm that.

If that's really it, I would put two turbines in their place: one for the moment when the wave hits and one for the moment when it withdraws.

Take a better look at the 1st info on this subject: a trick of the system lies in the fact that the turbine works in both directions of the "wind" while always turning in the same direction!

I don't know the technological details but I think it's a global innovation.
