Mariah Power has created a beautiful, tower-like wind power appliance: the Windspire. This propeller free design rises 30 feet into the air and is just 2 feet wide. Rotating at the speed of wind, it is quiet and safe for avian life, so there is no need to take down your bird-feeders. You can expect this 1 kw Windspire to produce 1,900 kw hrs annually if winds average 12 mph. Producers promise easy, DIY installation and low maintenance. Their website includes a calculator for determining how fast your Windspire will spin.
Windspires are expected to be available this fall. Reserve your own @ mariahpower.com
