And here's a wind turbine that looks simple to build.
Motorwind micro turbines can work in wind speeds of only 2m/second. Their light weight, small size, and flexible configuration allows them to be installed in both urban and rural environments, for individual or corporate use. Motorwind turbines give users a new option for efficient renewable energy and therefore reducing their impact on the environment.
$240
