Curving tip key to efficient new blade design

A new wind turbine blade being developed in the US uses a gently curving tip to increase the efficiency of electricity generation at low wind speed sites. Sean Ottelwell reports.

A new wind turbine blade design that researchers at Sandia National Laboratories developed in partnership with Knight & Carver (K&C) of San Diego promises to be more efficient than current designs. It could significantly reduce the cost-of-energy (COE) of wind turbines at low-wind-speed sites.
