Underwater Kites to Harness Tidal Power
Sweden-and Uk- based Minesto, has developed a new concept called Deep Green "Underwater Kites"; which uses hydrodynamics to harness tidal currents and makes the flow velocity to increase ten times.
The lite spins in a repeated manner by the force of the tidal current. This process will increase the flow speed entering the turbine ten times. When the tide hits the wing it turnsdown, and creates a little force. The kite is mounted to the ocean bed with a tether and is controlled by a rudder trajectory. This system will use a conventional plant to convert the movement onto electric power.
According to the company, the Deep Green Kite has a wingspan of 12 meters depth at sites with a tidal flow of 1.2 - 2.2 meters/second. The company estimates it'll cost Euro 0.06 - 0.14 per KWh. The company is now preparing to build a scale 1.4 prototype of the technology, which will be ready in 2011.
