WINDSPIRE: PROPELLER-FREE HOUSEHOLD TURBINE GETS APPROVAL

We just featured the largest wind turbine in the world, now here's something at the opposite end of the spectrum: a household wind turbine. In the last few years, we've seen a lot of mini-wind turbines that haven't turned out to be very useful. But the Windspire turbine from Mariah Power sounds interesting. The Windspire has a propeller-free vertical-axis design, and is expected to produce about 1800 kilowatt hours per year in 11 mph average wind conditions. That amount of wind power is roughly 25% of a typical household's energy (or much more if you are particularly energy efficient).

The Windspire is 30 feet tall with a two foot radius, sized below typical residential zoning restrictions. Guidelines for installation sites are generally half an acre of land and relatively windy locations. The Winspire has just passed the ETL safety certification, which means it's ready to go to market. It is expected to be released this spring, and priced at $3,995.
