Reinventing the Small Wind Turbine

Many commercially available small wind turbines with plastic blades and steel towers are infamous for their low reliability, high embodied energy, and limited power output. In fact, they have been addressed for more than two decades by Scottish engineer Hugh Piggott, who builds small 1-2 kW wind turbines with 2-4 meter rotor diameters using solid wooden blades. Of course, both approaches could be combined, resulting in small wind turbines with wooden blades, tower and other structural parts.
