Generating electricity using the current that flows through this stretch of water. Weighing 28 tonnes and with a 12 metre wingspan, the newest dragon can deliver 1. 2 megawatts of power. Its sort of like kitesurfing, but underwater. So we tether it off to the sea floor, foundation on the sea floor, and then it flies in a figure of eight. As underwater Currents Flow by, the kites wings generate a hydrodynamic lift force, spinning the turbine and generating electricity. This design� s very different to other types of tidal technology. So whats the advantage of a design like this one . We can install and operate and produce power in low flow currents with lightweight machines. Although it looks big to the eye, this is actually a very small tidal turbine. Weve designed the system as such to be maintenance friendly you simplyjust tow them in,
