Floating Contra-Rotating Wind Turbines That Can Produce Double the Energy
Wind is an inexhaustible, clean resource. Capturing these powerful gusts is a critical component of many plans to replace fossil fuels with renewable, eco-friendly energy. Norwegian company World Wide Wind has designed an innovative floating, vertical-axis wind turbine (VAWT). With two sets of “contra” blades, these turbines known as contra-rotating vertical turbines (CRVT) have the potential to double the output of traditional one-set turbines. They could offer a route to large-scale, less-expensive wind energy production.
