Want to build your own wind turbine? v3power have organised another course at Hill Holt Woods (off the A46 between Newark and Lincoln). Learn how to make all the parts of Hugh Piggott's successful turbine - carve the wooden blades, wind the copper coils, weld the frame, cast the stator from resin. See www.v3power.co.uk or e-mail  info@v3power.co.uk .
