Germany has a program (“A Million Points of Light”) to install wind turbines in homes. Finland has small vertical axis wind turbines going up in cottages, on chimneys.
Which is the best design for a home-power installation? What are the efficiencies of the different blade designs?
Anybody know anything about the ‘bent-prop’ design, like this one?

Does the chimney need to be reinforced?
How high does the wind turbine have to be, over the tallest house in the neighborhood?

Designed and made to pick up the wind power as much as possible. The efficiency is graded as 0.48 in converting wind power to the mechanical power, which is at the very top end (the highest is 0.5). The exact same blades are widely used in commercial wind generators. The performance of the blades is much better than home brewed ones.
