Abstract
A floating hybrid tidal/wave/wind energy harvesting system is described, wherein the system is based on vertical axis turbines for synergized tidal, wave and wind energy production. The system is self-starting and can continuously, and simultaneously, harvest wind and tidal energy in a wide range of wind and tidal current speeds.
Claims20
A floatable hybrid wind energy and tidal or wave energy harvesting system, said system comprising:
- (i) a first hybrid Darrieus-Modified-Savonius (HDMS) vertical axis turbine (VAT), wherein the first HDMS VAT comprises a combination of a first Modified Savonius (MS) turbine about a first central axis and a first Darrieus turbine positioned in an annular region surrounding the first MS turbine;
- (ii) a second HDMS VAT;
- and
- (iii) a floatable foundation, wherein the floatable foundation is a structure comprising at least one hollow section, wherein the structure is defined by a first side, a second side and an outer circumferential surface such that when the floatable foundation is in/on a body of water, the first side and second side are situated above and below a surface of the water, respectively, and wherein the floatable foundation further comprises one or more fins positioned along, and approximately perpendicular to, the outer circumferential surface of the structure,
- wherein the first HDMS VAT and the second HDMS VAT are positioned on the first side and the second side of the floatable foundation, respectively.
