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…
Here is my sperimental solar panel that heats both air and water, also provides a few hundred watts of electricity for small electrical utilities, follow the link for more details. Experimental panel that heats the air in the house and preheats the water from the solar thermal panel (solar circuit, not the sanitary one) to increase its efficiency in winter.…
Experimental solar panel that heats the air in the house in times of crisis. In this period where the energy crisis is making itself felt even in industrialized countries, this air solar panel can make a significant contribution to the domestic economy; the low cost of production makes it suitable even in developing states as well as in isolated areas…
