Underwater Kites that Could Harness Tidal Power

This design might look like any ordinary kite, swooping and diving along. However, it is actually a unique technology which it is hoped will convert ocean tidal currents into energy and produce electrical power miles below the water’s surface around Britain.
Formed in 2007, Swedish Company Minesto, a spin-off from the Saab group, has devised this unique underwater kite, named ‘Deep Green’, which is expected to come into service soon around Britain’s coast. In comparison with other existing methods of energy extraction, Deep Green is not only smaller in size, but is also very cost effective.
Mechanism: To understand how it works, let us discuss how tides are formed. Tidal currents are produced as a result of the gravitational attraction of the Sun, the Moon and the Earth’s rotation. Because of the varying gravitational pull between these forces, the oceans on each side of the globe rise and then fall back twice in a single day. In short, the greater the variation, the greater will be the tidal electricity generated. The energy extracted from such relative motion is called tidal power and is the only form of such energy in existence.
Deep Green underwater kites are basically tidal turbines with a diameter of one meter. These kites fly up from the ocean floor in a figure eight with a wing span of 12 meters. Each kite has a wing and rudder, which is attached to the bottom by means of a tether. The mechanism works in two phases:
Phase one: A lift force is created when the tide hits the wing, which increases the flow of water into the turbines 10 times faster than the current speed.
Phase two: The kinetic energy generated is then converted to electrical energy.
