Remote Tasmanian Island To Be Powered By 'Blowhole' Energy That Harnesses Waves
An anonymous reader quotes a report from The Guardian: Technology that harnesses wave energy through a "blowhole" is being tested at a remote Tasmanian island in a project backed by federal grants and investors. When the mostly above-water unit is connected in about a month, King Island in Bass Strait will be powered by three renewables -- wave, wind and solar. And there are hopes the project can be expanded across Australia's vast southern coastline. Wave Swell Energy co-founder Tom Denniss says the pilot will provide crucial data about the system's potential. "It's very much like an artificial blowhole," he said. "There's a big underwater chamber that's open out the front, so the water is forced into the chamber. "It pushes that air back and forth. The movement of air that spins the turbine and produces electricity." Research by the peak scientific body estimates wave energy could contribute up to 11% of the nation's energy by 2050, the equivalent of a city the size of Melbourne. The boat-like structure can generate up to 200kW of power but there are plans for larger 1,000kW models.
