Marc 22 years old from Parisian suburbs (Near Orly airport) I presented for a year-end project (this year) in Jussieu a retrofitted mower that works impeccably (well I still have waterproofing problems but it works) At the moment I am also on a 205 where I work with ...

I was also there with three other delinquents that you may have spotted if you were at the Saturday night loto-theater (vacuuming and "rescue") or during the folk dances. I think it is important to situate the context: a farm where Claude, an ecologist (or similar for those who do not ...

A lot of little magazines explain how to build your thermal solar collector: it's ultimately quite simple: a wooden frame, a black background, a copper coil, a window on top and good insulation and voila. You can add an expansion tank and a valve for ...

Hello everyone, having seen several small hydropower plants in operation in recent months, I can confirm several things. Their characteristic, in terms of power, is not to exceed 10MW (threshold between small and large hydraulic). Small hydropower plants ...

After visiting the Mont Soleil wind farm in Switzerland, I was flabbergasted by the absence of noise from these 70 m high monsters: at about fifty meters, the wind in the shrubs completely covered the noise of the blades. From just below, the noise is about twice as loud as that ...

Do you have examples of installations with interesting feedback, sites of information on this subject to advise?
