I live on 12 acres of land in a very windy place, where average wind speeds are almost 30mph. In light of this, I really feel I could exploit wind to power my home and was thinking of a 10kw or greater turbine. Any idea what the best way to go about this is? I see loads of DIY turbine options for small scale wind generation, utilizing treadmill motors, scooter motors, washing machine motors etc. But what about if I want to build a turbine 10kw or more? Are there any cheap motor options that I can re-purpose?
