Yeah, they keep telling us the tech is still young, however we've had windmills for centuries! I guess they mean the generator style eh? I laugh at times when they say they have to feather them & turn them off because it's too windy! Wot a crock o shite! I'm all for "alternative energy sources" Solar, Wind Wave, Geotherm all good things but so expensive...I've I won millions I'd build my own house with all the "Green" tech I could get my hands on...Get myself an electric car that runs on the power generated by my own tech...Ah Dreams eh?
