Wedge W1
The Wedge W1 is an as an axisymmetric resonant point absorber designed to harness the vertical motion of sea waves. The system consists mainly of a combined ring-like "floater" and a tube-like "spar" that rests on the surface of the sea and is anchored to the seabed. As waves pass, the floater rides up and down spar. This relative motion between the floater and the spar drives an internal power take off (PTO)–a linear electromechanical generator which generates electricity. Through several R&D projects, including testing of a 200kW prototype at the PLOCAN test site, Wedge Global SL has improved their technology in sub-areas of, inter alia, power-take-off, transmission, electrical and energy engineering, naval design and station keeping, with a reported technology readiness level (TRL) of 8.
