A Nevadan company, Mariah Power, has launched a unique wind turbine for the home, called the WindSpire. The turbine is rated at 1 kilowatt, and it has a thin design — it’s only two feet wide, but 20 feet tall (see a photo here). The color is also customizable — suggested colors are: Milky White, Forest Green, Sky Blue, Stop Sign Red, or Crystal Clear. You can see a video of the turbine in full-tilt action here. It’s designed to be easy to install, and it’s rated to survive in winds up to 100 mph. The minimum wind speed necessary for the unit to begin generating power is only 8 mph. It also said to be very quiet. The price is $3995 and the product is scheduled for delivery in the fall.
EcoWorld spoke with Mariah Power recently:
When I met Mariah Power’s VP of Marketing, Tracy Twist, last week in Sacramento…Standing on a 10 foot tower, with the inverter and generator attached immediately to the bottom of the rotor, this windmill appears simpler to manufacture and maintain compared to traditional horizontal axis windmills.
The problem has been getting sufficient efficiency from the rotor. Because vertical wind rotors have a lower RPM compared to conventional wind rotors, the challenge has been to find a generator that can still generate adequate power at these lower speeds. Mariah Power has patents pending on their generator which they believe have solved this problem. They have three prototype generators already constructed which they have submitted to 3rd party testing centers to verify their claims.
