Could a Roof-Top Windmill Provide 80 Percent of a Home's Energy?
• HeraldTribune.comThe first of his Democratic Ecology products is to be launched this fall, a miniature roof-top windmill, priced between €500 and €800, which will produce up to 80 percent of a home's energy.
Not unless the wind blows at 15mph for 80% of the time. Otherwise its a pretty dumb idea.
What tripe. The story doesn't give a swept area of the rotor but it need to be pretty large and be in a constant medium to high wind area to be able to supply the energy needs of a modern home. Just another stories to make people believe that energy use/production is such an easy problem to fix. Few hundred bucks and slap it on the roof and Budabing no more electric bill…..NOT
I note the article was completely bereft of any detail. 15 minutes to install something that has to weigh a lot and connected to 220V.
Also, you generally want to get the blades about 30 feet off the ground to have a decent amount of near constant breeze. I am attracted to the design. I just would like to see the specs and proof of design.
