When I think of wind power I think of these huge blades spinning around and creating a couple of megawatts of power, not a in my backyard kind of device. Well Mariah Power has create an affordable $4,000 vertical wind turbine that produces 1kW of power and stand only 30 feet tall!
The Windspire is a vertical wind turbine that stands about 30 feet tall and 2 feet wide. The perfect wind turbine for DIYers. Many â€œwind bashersâ€ find vertical wind turbines better then horizontal wind turbines due to the â€œpossibilityâ€ of bird killing via migration. I find this HARD to believe and hear much of the SAME people bashing cell phone antennas and TALL BUILDINGS. Think about it, do you see birds flying into a huge building, NO so why would they fly into a spinning blade. (sorry for the rant, ugh I just hate those people who complain and do NOT understand the FACTS!)
Anyway, The Windspire is a rugged and simple constructed vertical wind turbine that has limited maintains. It produces about 25 decibels of noise at five feet, which is about the same as a noise neighborhood house. The Windspire only needs a 8 MPH gust of wind to produce power and can survive up to 100 MPH winds!
The most interesting part that would make me buy a Windspire is the fact the Windspire also includes an internal wireless modem that can continuously transmit power production information directly to your computer so you can check your power production at any time. Monitor your offset and see how fast you can pay it off. At 10 cents a kilowatt it takes about 20 years to pay it off, but at $4,000 a nice investment for the green person inside you.
