New Bladeless Wind Turbine Claimed to be Twice as Efficient as Conventional Designs

New Bladeless Wind Turbine Claimed to be Twice as Efficient as Conventional Designs

When it comes to the future of wind power, one company thinks it looks a lot different than you would expect, and cheaper and more efficient to boot. Saphon, out of Tunisia, is interested in finding partners to mass-produce and market their unique wind energy device, based on their own Zero Blade technology. "The Zero-Blade Technology is largely inspired from the sailboat and is likely to increase the efficiency of the current wind power conversion devices. The blades are replaced by a sail shaped body while both hub and gearbox are removed." According to the company, their zero-blade technology devices are capable of overcoming the Betz' limit , which states that no turbine can capture more than 59.3 percent of the kinetic energy of the wind . An average wind turbine captures only 30 to 40%, while the Saphon turbine is said to be 2.3 times more efficient. Additionally, th...
