Thanks for the reply. 1.5 m diameter is nice and compact. I've got many low energy heating and cooling aspects pretty well worked out as they will be on the house when it is build. This includes an array of solar panels on a 2.4 m x 8.5 m roof. Should be able to get 2 to 3 kW peak, which should just about make us electric energy neutral. I'm trying to allow in the construction for a possible wind generator. As mentioned, rather than using a pole, blades and generator would be housed in the roof. A 14 m long tunnel would funnel any wind energy in past the generator. Keeping in mind it's early days and all I'm doing is making sure the roof space can accommodate the possible future concept I have some ideas. Firstly, it doesn't matter if the wind is driving at an angle to the tunnel, all that would mean is that it's effective length would be reduced - by the sine of the wind's direction would be my first order approximation. Therefore if the wind was at 45 degrees to the axis of the tunnel, the effective length would be about 10 m. Still a good length. I can let you know how my low energy heating and cooling goes in about 2 years, but the wind-turbine-in-roof-tunnel will have to wait for several years beyond this. But I like the idea!
