Wind turbines. Enough to supply about 10.000 kWh or 10 MWh annually. "We built a 1000 watt wind turbine to help charge the battery bank that powers our offgrid home. It's a permanent magnet alternator, generating 3 phase ac, rectified to dc, and fed to a charge controller. The magnets spin with the wind, the coils are fixed, so no brushes or slip rings necessary." - MUCH cheaper. Just one foot. Designed to give to higher windspeeds, possibly by using a semi-flexible foot.
HHO Generator - Water to Fuel Converter
Splicing water bottles. For storing compressed oxygen to be used with ethanol/aluminium powder gas jet burner/furnace. Either this or a used propane tank.
