Series A · Brondby, Capital Region of Denmark · founded 2003$15.7Mraised▾
Provider of multi point absorber WEC. WEC draws energy from wave power with floats that rise and fall with the up and down motion of waves. Wave Star consists has partially submerged hemisphere-shaped floats that each drive a hydraulic pump. The floats are attached by arms to a platform that stands on legs secured to the seafloor in such a way that it is positioned at right angles to the approaching waves. The motion of the floats is transferred via hydraulics into the rotation of a generator, producing electricity.
