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...

To tell the truth, this is not the subject of the subject.
But to answer your question, ethanol (hydrated or not) goes from the first generation to the second by changing the raw material. (if ever, there is more info on the site on this)

Anything that can encourage an increased use of first generation biofuels only maximizes their harmful agronomic consequences ... Yes, then seen like that, the situation becomes immediately becomes much clearer on hydrated ethanol ... avoid an agronomically born debate ...

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 ...

So ask your "paranoid friends" who forward you this kind of shit to find the university studies concerning the so-called harmfulness of EM waves of fluorescent bulbs but especially on fluorescent tubes (neon) that we have been using for 80 years? 1 ° Which "paranoid friends"? I ...

how much is the electromagnetic pollution of transformers (in numbers)? It would be interesting to try on laptop chargers by the way (transformers and converters) ... Indeed, not at all ... Sincerely sorry. I know you sell that kind of bulb and that kind ...
