New approach to wind energy – much more efficient

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. Instead of spinning the blades’ rotor, the wind is being harnessed by a sail which follows a non-rotational back and forth motion. Such movement follows a knot path and allows the conversion of the majority of the kinetic energy into mechanical energy (using pistons). The same is then converted to a hydraulic pressure that could either be stored (in hydraulic accumulator) or instantly converted to electricity via a hydraulic motor and a generator. Thanks to the aerodynamic shape of the Saphonian, the drag force becomes the driving force of the system while the lift force becomes almost nil.
