Windspire Wind Turbine Modeled After Ancient Egyptian Windmill

As wind power is getting a lot of attention here in NC, both in the mountains and off the Outer Banks, I thought it was fitting to cover Windspire wind turbines, which were present at President Obama’s inauguration festivities.

These 30 foot tall and four foot wide wind turbines are different than propeller-based systems; they generate power when the wind blows against vertical airfoils, which is then converted to AC electricity. Each wind turbine produces about 2,000 kilowatt (KW) hours per year in 12 mph average winds, and includes wireless monitoring software so power production can be checked.

Windspire wind turbines cost $9,000 to $12,000, but after rebates they could cost as little as $3,800. There is a 30 percent federal tax credit available, plus local rebates are available in some areas. The average payback is under ten years for the turbines that are designed to last over 20 years. According to Windustry, a wind turbine that's capable of powering an average home costs $35,000 to $50,000.

Founded in 2005, Mariah Power launched its Windspire wind turbines in 2008. A Michigan plant began producing the wind turbines in April. The factory used to make automation equipment for all of the major car manufacturers. They were down to five employees when they met with Mariah Power to show how they could make the Windspire with better quality and for a better price. Most of the people who were laid off have been rehired now to work on the Windspire. The plant was featured on ABC's 20/20 on Friday, June 19th.
