UMLAUFENDER ENERGIEUMWANDLER UND VORRICHTUNG ZUR GEWINNUNG VON ENERGIE AUS OBERFLAECHENQUELLEN

摘要

A rotary transducer adapted to be driven in the same direction by air flow therethrough in either axial direction comprises a rotor having blades of aerofoil cross-section which are fixed with their planes of zero lift normal to the axis of the rotor. An apparatus for use in extracting energy from the waves of the sea utilizes such a transducer.
