FloDesign wind turbine
Massachusetts-based FloDesign has developed a wind turbine that could generate electricity at half the cost of conventional wind turbines. The company's design, which draws on technology developed for jet engines, circumvents a fundamental limit to conventional wind turbines. Typically, as wind approaches a turbine, almost half of the air is forced around the blades rather than through them and the energy in that deflected wind is lost, but by using a shroud design, the company says it is able to generate as much power as a conventional wind turbine with blades twice as big in diameter.
