Improving the efficiency of an economical wind generator
I experimented with a 100 euro generator, rated 500W but in reality it produces much less in normal wind, and in low winds (below 7.2 km/h = 2 m/s = 4.4 mph) it produces nothing. From the measurements in low winds however are obtained 5V/7V in open circuit with a short-circuit current of around 1.5A, so there is some energy…
