Underwater kite, recipe for energy security

This is about an amazing invention of 2010. In Times magazine of November 11, 2010 says one of the 50 best inventions of the year is Deep Green Underwater Kite. Swedish company Minesto's underwater kite resembles a child's toy, as it swoops and dives in ocean currents. But since sea water is 800 times as dense as air, the small turbine, tethered to the ocean floor and attached to the kite, can generate 800 times more energy than if it were in the sky.
Minesto calls the technology Deep Green and says it can generate 500 Kilowatts of power even in calm waters, the design could increase the market for tidal power by 80 per cent, the company says. The first scale model will be unveiled next year off the coast of Northern Ireland.
The Deep Green technology converts force from tidal stream flows into electrical energy by way of a novel principle, somewhat similar to the posture of a wind kite. The kite assembly consist a wing and turbine attached to a fixed point on the ocean bed. The technology offered by Minesto is lightweight and minuscule compared to other tidal solutions.
Resulting in cost savings in material, transport, installation, service and maintenance, which place Minesto in a unique position, both economically and in terms of the number of available sites.
Deep Green can operate cost efficiently at sites with low current velocities and at large depth, therefore able to significantly expand size to a huge marine area. Rated power: 0.5MW; Weight/ Effect: 14 tonnes/ MW; Mean velocity: 1.6m/s, Cost/ Kwh: Euro 0.06- 0.14.
Bangladesh can introduce this Deep Green technology to produce electricity in the coastal areas of Chittagong and Mongla for better energy security.
