I love when the technique is still let by mysteries!

Perhaps thanks to the Christmas lights, we will discover a new phenomenon that produces energy.
It would be a nice gift!

@Indy49, Awareness, I think it has unfortunately been there for a long time at the citizen level but I am one of the followers of Pareto ( http://fr.wikipedia.org/wiki/Distribution_de_Pareto ) who think that most of us (80% of the population) can only intervene on...

Hello, I come back to the topic of the wind turbine. What do you recommend to protect my wind turbine in strong winds: feathering or braking the rotor? - In the first case, it's slow to see that as soon as there is a great wind energy potential, we have to stop everything! - In the second ...

Thanks jam for your answer. I read diagonally what had written on the effect of cavitation but it seems that for the moment a "heating by cavitation" is not technically developed. On the other hand, what is written is very interesting and will undoubtedly lead to new decorations ...

"The energy of the vacuum has been proven to exist, no problem, it's the Casimir effect". I think the Casimir effect is the convergence of the Butterfly effect and the Spaghetti effect! - On the one hand there are phenomena so insignificant that it is difficult to measure them and to measure the ...
