Peak Energy: Tidal power gets a boost from propeller and wind turbine techonology - 0 views

Energy Net on 13 Jan 09The Guardian has a report on some new tidal power technology from a company in Wales inspired by ship propellers and wind turbines - Tidal power gets a boost from propeller and wind turbine techonology. Propellers on ships have been tried and tested for centuries in the rough and unforgiving environment of the sea: now this long-proven technology will be used in reverse to harness clean energy from the UK's powerful tides. The tides that surge around the UK's coasts could provide up to a quarter of the nation's electricity, without any carbon emissions. But life in the stormy seas is harsh and existing equipment - long-bladed underwater wind turbines - is prone to failure.A Welsh renewable energy company has teamed up with ship propulsion experts to design a new marine turbine which they believe is far more robust.
