Savonius Wind Turbine

You included two kinds of water turbines, but only horizontal shaft wind turbines. I think you should have included the easiest of all wind turbines to build, the Savonius turbine. It can be created easily from two half drums with 1/3 center overlap. The issue of high high rotational speed is actualy solved with increased efficency by creating large diameter rotors which still provide the high magnet speed and the larger spacing of the magnets avoids magnetic interference. Also VAWTs avoid the need for slip contacts or bevel gears.
