Wind Power

The FT has an article today about David Gordon, chief executive of Windsave. Windsave make domestic wind turbines, which you can just plug into a 13 amp socket - which is a nice feature. But, they're expensive, and even Windsave think that only 20% of houses have sufficient wind to make them worthwhile.

The problem with domestic wind turbines is that most towns and cities are built in river valleys, where they don't get much wind. Worse, the buildings create turbulence, which reduces the turbine efficiency (they find it hard to remain pointing into the wind), and life span.
