Harvesting Tidal Energy with an Underwater Kite

Harvesting Tidal Energy with an Underwater Kite

A new sort of tidal energy device that looks like an underwater kite offers the promise of clean energy generation from low-velocity currents in the ocean. Many tidal energy solutions require a location with higher velocity currents, or to be at or near the surface of the ocean, which limits their application, but the Deep Green device is said to be suitable for operating in deep waters with low velocity currents( 1-2.5 m/s), which greatly increases the number of possible locations. Combining a tethered wing and a turbine, the Minesto Deep Green device “flies” underwater, using the ocean current to… read more

Scotland to Build World’s Largest Wave Farm


A project that will culminate in the world’s largest wave farm, ultimately delivering 40MW of clean energy, has received approval from Scottish Ministers and will deployed off the coast of Scotland. The project, using Aquamarine Power’s “Oyster” technology, will deploy 40 to 50 of the near-shore wave energy harvesting machines in the ocean off of the northwest coast of Lewis over the next few years. “Aquamarine Power’s Oyster wave power technology captures energy in nearshore waves and converts it into clean sustainable electricity. Essentially Oyster is a wave-powered pump which pushes high pressure water to drive an onshore hydro-electric turbine…. read more
