Minesto Dragon 12
Minesto’s technology generates electricity from tidal streams and ocean currents by a unique and patented principle similar to a kite flying in the wind. The wing uses the hydrodynamic lift force created by the underwater current to move the kite. With an onboard control system, the kite is autonomously steered in a predetermined figure-of-eight trajectory, pulling the turbine through the water at a water flow several times higher than the actual stream speed. The turbine shaft turns the generator which outputs electricity to the grid via a power cable in the tether and a seabed umbilical to the shore. Dragon 12 has a rated power of 1.2 MW and is designed for utility-scale energy systems.
