We had some really great threads last year, with the following four nominated for the Thread of the Year award in this January's Environment Site Awards ceremony.
Floating wind turbines take advantage of air currents along the length of their shaft to generate electricity. Selsam’s prototypes produce 6000 watts in 32.5 mph winds - six times more power than a similarly sized seven foot single-rotor turbine can produce.
Pretty neat design. It could easily be adapted for use on ground too. Just make a weighted base filled with concrete to act like the water filled mechanism use on the sea based turbins. The axis could be free floating to pivot and for 360 degree control.
