• Rooftop wind turbine without moving blades, where the vacuum created is ducted past a bladed generator head that is located below the wind-swept area. This is at the 5kW scale, producing 334 watts 24/7 year round in 9 mph average wind speed. A single one would produce sufficient auxiliary power for the Seed Eco-Home night time use.

• Appears to be $2400/kW installed capacity. But, note that the 5kW 'installed capacity' is really 334W at 9 mph - which is 5x more expensive than solar accounting for a 25% daily duty cycle of PV for a realistic comparison.
