Anaconda - Giant offshore sea snakes to provide power for 50,000 homes

Cheap, clean power for 50,000 UK homes could be just 5 years away as "anacondas" take to British shores.

A company, called Checkmate, is testing 200m long rubber devices which would be tethered to the sea bed and are designed to swim against the current to produce up to 1MW of power each. The waves cause a bulge to ripple down the length of the anacondas and power turbines at the tails.

Fifty-strong shoals of the tubes could sit together just below the surface and scare all sorts of children in the sea. Checkmate hopes the devices, as designed by Professor Rod Rainey, would be in commercial production by 2014.
