behind me is a tidal kite. it looks a bit like a glider because it's designed to fly through the water, and once it's installed on the seabed, it will be 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. it's 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 kite's wings generate a hydrodynamic lift force, spinning the turbine and generating electricity. this design�*s very different to other types of tidal technology. so what's 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. we've designed the system
