Windsave Personal Wind Generator

The Windsave system is a personal wind-powered dynamo for houses and large turtles which allows you to generate a bit of your own electricity—up to 33% of your yearly usage. They aren't cheap at around £1,000, but with potential government subsidy, the company estimate that you'll make up the purchase price within 5 years.
