Everyone commenting that this can't be made for less than $30 please first read the materials section of the build tutorial: http://opensourcelowtech.org/wind_tur... All the relevant information is there. Facebook discussion group: https://www.facebook.com/groups/windt... This is the up to date build process for the OpenSourceLowTech.org $30 Lenz2 vertical axis wind turbine. The turbine can be made almost entirely from recycled materials with basic tools in six hours for $20-35. It is tested at 35-40% mechanically efficient, generates 130 watts mechanical in a 30 km/h wind, 1 kilowatt at 60 km/h, and can survive 100 km/h gusts.
