A Newly Electric Green – Sustainable Energy, Resources and Design
A team-up of engineers from the Lawrence Berkeley National Laboratory and the Makeyev State Rocket Center in Miass, Russia has developed a new model of wind turbine for home use. The “Wind Sail” design is a vertical axis wind turbine (VAWT), and are designed to be used as generators for off-the-grid and distributed-grid systems. The current production model, the WPU-2500, produces 2500 kilowatt hours over the course of a year in typical wind conditions.
VAWT systems have several advantages over more traditional horizontal axis wind turbines. They scale down more efficiently, are usually quieter, and have a much lower rate of bird kills — predatory birds can even rest on the top of a VAWT without trouble. The Wind-Sail system adds another benefit: former weapon designers no longer on the global market.
