Your Questions About Wind Turbines For Sale

What is the cheapest wind-turbine for sale in the UK for domestic installation?

SURVEY: How much would you pay for a small 300-watt wind turbine on your chimney or roof, or just the plans?

I’m thinking of making some wind turbines, or just the plans, for sale, , with a quiet design like the ones in these websites:

Also, would this be for a home, cottage, or other building? What voltage output would you prefer?

Please specify your city and country, thanks.

FYI, my first turbine will be to charge an electric car, like the one in this video..
