Energy converter for converting fluid medium flow energy, preferably wind energy, into electrical power has medium blade(s) rotated by fluid medium, piezoelectric element(s) on e.g. cylinder rotated by blade

摘要

The energy converter has at least one medium blade (12) that is rotated by the fluid medium and at least one piezoelectric element (14) that can be arranged on a cylinder (2) rotated by the blade or on a polygonal body rotated by the blade. The piezoelectric element can be mounted on a rigid plate that is alternately covered by a shield mounted on a plate that is rotated by the blade.
