Title: (EN) A DEVICE FOR THE UTILISATION OF WAVE ENERGY AND A METHOD
Abstract:
(EN) Patent 591237 The disclosure relates to a device for the utilisation of wave energy, with an increased efficiency. Thereto, the device according to the invention comprises - a Darrieus rotor having at least two Darrieus rotor blades, wherein the Darrieus rotor has a solidity sD, and - a Wells rotor having at least two Wells rotor blades, wherein the Wells rotor has a solidity sW, wherein - the Darrieus rotor and the Wells rotor are rotatable about a common axis of rotation A, and - sW is larger than or equal to sD. The disclosure also relates to a method for harnessing wave energy.
