SeaTwirl

Sea Twirl is a vertical floating wind turbine currently being tested off the west coast of Sweden. The design enables the use of cheaper, heavier materials and continuing generation of power when the wind is low.

The design was developed by Daniel Ehrnberg.[1] Chalmers University of Technology built a prototype[2] and tested it at SSPA.[3] A third-generation prototype was installed off the west coast of Sweden near Halmstad in August 2011.[4][5]

SeaTwirl is one of a few advanced designs in that it floats and can therefore be positioned far offshore and take advantage of the stronger winds there.[6] The SeaTwirl design uses the seawater itself as a roller bearing and stores energy in a water-filled torus. This enables the use of cheaper and heavier materials and the generation of energy even when the wind is not blowing.[1][2][4][7][8]
