We're proud to present the latest prototype of our Vertical Axis Wind Turbine. This promises to be the most efficient turbine ever developed with a vertical axis. We've made a major breakthrough in aerodynamics; our turbine is as efficient as any conventional horizontal axis wind turbine, something the experts said could never be done!
