Belfast Telegraph - 28/02/11



Technology using an underwater "kite" to generate electricity from tides is to receive a 350,000 grant to test a prototype in the UK's seas, the Carbon Trust revealed.

If the trial, which will put a small-scale device through its paces off the Northern Irish coast is successful, the developer behind the scheme wants to put enough structures in the seas to power all homes in a city the size of Newcastle.

The device works like a kite tethered to the seabed while "flying" through the sea current carrying a turbine.

Cool I note that the last line of the article states that tidal power could provide 5% of the UK's needs. I would have guessed it would be quite a bit more then that but these people are working the problem and have a much better grasp of the figures then I. Still 5% would be 5% that was emission free and totally renewable and not purchased from the middle east or Russia. Also any area studded with under water kites and cables would have to be closed to all fishing and would provide a fish propagation area that might be of more benefit then the electric power produced.

But is that 5% of current needs, or 5% of needs after our 80% reduction in emissions by 2050? It may produce a large percentage of the latter.

Question How does reducing emissions reduce needs? If anything closing a coal fired plant to reduce emissions leaves a large chunk of demand that needs to be replaced by some other non emitting means. Conservation and closing manufactoring plants count of course but electrifying rail lines and charging plug in electric cars counter that. The question is does the government have a plan that adds up all the pluses and minuses and has all the lights still on (LEDs included) or do they have the cart before the horse and are set to close plants before their replacement is on line or the demand has been removed.
Having worked for governments for years I think I know the answer to that even from this side of the pond.

By moving to a lifestyle that uses less energy. The bit the government hasn't really told anyone about!
