Tqing 8000W Wind Turbine Generator Kit, Vertical Wind Generator Electricity Producer Equipment for Home Power Energy, 12V

Bought this because it looked promising but no, it wobbles and rattles away on the pole, but there is still hope because I worked out that if I can get this thing up to around 30 million rpm I might be able to get a watt or two out of it, according to the seller it wasn't spinning fast enough but I reckon if its not spinning fast enough in 56mph wind its never going to. So morale of the story is unless you live somewhere with a sustained 500mph wind this is probably not your best choice of turbine. O I nearly forgot to mention that the seller is useless as well, absolute no help from them at all

No battery was included (even though stated in the description) and the controller provided is basic. Installation instructions are simple enough (one page with pics) but no manual. Probably suitable for individuals with an electrical background.
