It does, but the place where you normally want that heat is around=20

I wouldn't bother.  My village has a wind farm next to it with 10=20
(soon to be 17) 100m-tall 2MW turbines.  Despite there seeming to be=20
an endless supply of wind round here, they have managed to average=20
only 18% of that capacity (even lower than government estimates=20
suggesting 26% as a reasonable expectation).

In my next house I'm going to look into getting solar heating for=20
water.  I think that would be a more effective (and quieter!)=20
investment than a wind turbine.
