MkII Now available! This fully functional wind turbine has been specifically design to be manufactured, assembled and operated at home with its unique 3d printable design. The wind turbine is optimized to produce a power output of 5 Watt (12volt ~4amps) at 5m/s wind speeds, perfect for battery charging applications. The wind turbine has been designed with a unique Passive Variable Pitch (PVP) design. The PVP maintains an optimum power output through control of the turbines rotational speed. Whilst optimizing power output the PVP also protects the Turbine from dangerous over speed conditions, limiting its maximum revolutions per minute in wind speeds greater than 5m/s. The main components of the turbine have been designed for Additive Layer Manufacturing (ALM) methods using PLA plastic. 95% of the ALM components require no post processing as these parts do not require ‘print supports’ reducing material usage whilst improving the overall finish of the part.
