Gallery: Underwater Kite Turbines Harvest Energy From Ocean Waves


Wave power generators generally take the form of sea snake-like designs that sit atop rolling waves, gathering kinetic energy and turning it into power. However a new idea combines the worlds of wind power and wave power to create underwater kite-turbines. Designed by Swedish renewable energy company Minesto, each underwater kite spans 8-14 meters and features a turbine attached to its underbelly. Each kit is tethered to the sea floor and it can “fly” with the tidal stream in a figure-8 motion.

    I assume the concern for protecting sea life is great. Why does it need to be in the ocean though? Can\’t this idea be used in man made tanks with no ecosystem?

    This will still have an effect on fish. If this turbine spins fast enough then the energy created by the fins to pull things into it will be immense and although fish will not go through the turbine might get caught on the protective barrier and be unable to swim off. I am not an activist or anything and i think that even if this is a risk it is necessary I’m just saying don’t you think that you will have problems with fish getting stuck on the protective net or whatever is protecting it.

    What about smaller ones for rivers? No dams or obstacles for fish.
