The UK could come closer to meeting renewable energy targets if the trial of a new wave generation device scheduled for later this year is successful.Essex-based Trident Energy is to test a prototype off the coast of East Anglia in autumn.The device is a platform anchored to the sea bed from which floats descend onto the surface of the sea. These rise and fall with the waves, creating relative motion between two components of the linear generator resulting in electricity.Spokeswoman Kate Hill said: "Trident is looking to develop a marine renewable energy system and this machine uses quite simple technology. It has one moving part which sits on the sea and generates electricity from the movement of the waves."We do not have a definite date as yet, but the sea trial should be ready to start in the early autumn."Early estimates suggest that if the technology were deployed across a half mile squared area, it could generate sufficient electricity for 60,000 homes.
