Thanks to a recently passed ETL (safety) certification for the U.S. and Canada, the company is now on the fast-track to releasing the product in early 2008 at a price of $3,995.

Not only will this turbine work in wind conditions that are prevalent through almost 60% of the United States, but it will also be much easier to install than previous wind systems. Windspire features a fully integrated, plug ‘n produce design, including a high efficiency generator, integrated inverter, and wireless performance monitor. It incorporates a slow speed giromill rotor for virtually silent operation and improved safety and durability. From the article,

Windspire features a new design that incorporates a tall, slender vertical style rotor that maximizes efficiency to produce strong, reliable performance. It is expected to produce about 1800 kilowatt hours per year in 11 mile per hour average wind speed conditions.It 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. It is priced at half to a third the cost of comparable renewable power options, and can be quickly and easily installed by authorized dealers.

Sounds like a great system to me. Savings for the average American home are expected to be about 25% per year. Throw in the quiet operation, limited height requirements, and current tax breaks — and wind is looking like a much more agreeable option for those without consistent access to solar.
