New wind turbine converts ambient airflow into sailboat electricity

Belgian startup Philéole has introduced Grain Blanc, a compact vertical-axis wind turbine designed specifically for sailboats to generate electricity from ambient airflow while underway. Mounted on the mast, Grain Blanc captures wind from any direction, unlike traditional horizontal turbines that require orientation toward the wind. This makes it highly effective in the constantly shifting wind conditions typical of marine environments. The turbine is lightweight, about one meter tall and less than half a meter in diameter, allowing easy integration without interfering with sails or deck operations. Its three-phase alternator with an integrated rectifier ensures consistent power output even in turbulent or irregular winds, supplying energy to essential onboard systems such as navigation, communications, and control consoles. The turbine also operates while moored, maintaining battery charge and supporting equipment like dehumidifiers. Philéole has emphasized quiet operation and low vibration in the Grain Blanc design to enhance sailor comfort and minimize disturbance to marine wildlife. Beyond sailing, the company offers the turbine in three ranges—Sailing, Building, and
