MPS WaveSub
WaveSub has a unique orbital energy capture mechanism – directly and efficiently harnessing the subsurface orbital energy flow of the waves. Each energy capture float can capture over 1.5 megawatts of power, and each WaveSub device has multiple floats, leading to significant multi megawatt power output per machine. With the rated power of the first commercial generation starting at 4.5MW, increasing to circa 10MW in future generations, WaveSub is the only WEC with a power output and cost profile that is comparable to modern wind turbines. WaveSub can survive storms by retracting the float securely against the base deep underwater, well beneath the harsh conditions on the sea surface.
