The tide is high, but submerged kites off the shore of the Faroe Islands are holdin’ on. The kites are part of the Faroe Islands Space Program, which consists of three kites connected to the seabed by subsea cables. Fitted with generators, the kites collect energy from the underwater currents and tides as they move in a figure 8 pattern. That energy then travels through the subsea cables to transformers on the shore of the Faroe Islands, an archipelago that’s a territory of Denmark. The project is the brainchild of Minesto, a Swedish tidal energy company. When complete, the program will consist of six kites with infrastructure connected to the islands’ electrical grid, which will provide energy to locals. It’s dubbed the Faroe Islands Space Program because tides are considered a lunar resource. “As long as the moon stays in its orbit,” Minesto CEO Martin Edlund told Tech Brew, “we are in production mode.” That means tidal energy is an always-on renewable, or a baseload form of energy. The energy itself is kinetic, harvested from the intensity of water flow, and Minesto’s tidal technology can collect energy from low flow tides as well as higher, more powerful currents. “We use the same principle as kite flying, but we do it submerged in the water,” Edlund said. “We fly on the linear movement of the ocean.” Keep reading here.—TC |
