Interesting vertical axis, magnetically levitated, wind turbine from Enviro Energies in Ontario, Canada. I don't see a whole bunch of information about output but it is certainly a different model.

Rated output of 2.5 kW and maximum output of 4.3 kW. Various sail assembly sizes available ranging from 4'h x 8'd to 6'h x 12'd. Can be utilized in most wind conditions. Power generation in as low as 4 mph of wind. 3.6 kW inverter system. Ideal for eliminating peak usage in homes, hybrid installations, back-up power, remote power, or installed in arrays along roof lines for a great architectural presence.
