Re: Comparison of wind turbines?
Yes, but the condition is that it can actually produce 300W, and not just 50 max in strong winds, and not just a few W with "normal winds". Hence the question of comparisons, to avoid installing a wind turbine which would require too strong a wind to start, or which will be...

Re: Comparison of wind turbines?
All around my house, I have wind turbines. I will make one, one of these days, with a lot of recovery, and few euros on the table, because there will be little return, but I think, that "with the signs, it becomes almost obligatory, when possible. Yes, but my thinking is that even with...

Wind turbine comparison?
Does anyone know of objective comparisons of wind turbines? Either from a technical point of view (wind turbines with horizontal or vertical axis, depending on the shape of the blades): some wind turbines start at lower speed/or resist higher speed, others are noisier, more...

Hydrous ethanol hE15
I just saw an interesting site on hydrated ethanol (~ 5-10%). There is in particular an advantage of gain during manufacture where the dehydration step is eliminated (therefore the yield is improved). Has anyone ever heard of it? or tried ?? Note: by hE15 we mean: 85% ess ...
