TheVat Posted November 16, 2022 Share Posted November 16, 2022 ABOARD THE PLAT-I 6.40 GENERATING PLATFORM, Nova Scotia — The Bay of Fundy, off the Canadian provinces of Nova Scotia and New Brunswick, has long tantalized and frustrated engineers hoping to harness its record-setting 50-foot high tide to generate electricity. After more than a century of attempts, there has only been one small power-generating station, since closed, and countless broken dreams, abandoned plans and bankruptcies. Even so, a new coalition of entrepreneurs and scientists in Nova Scotia are trying again. One participant, a company called Sustainable Marine, has devised a new technology and successfully operated it for more than seven months, longer than any other similar system, producing enough electricity for about 250 homes. Sustainable Marine’s innovation is that rather than placing stationary turbines onto the seabed as has been tried in the past, it floats movable ones on the surface, lifting them when a dangerous object approaches and for maintenance. If the platform continues to prove reliable, is economically viable and doesn’t harm marine life, it will have harnessed not just a new source of renewable energy, but also one of the most reliable ones in the world. Because unlike wind or sunshine, tides are unceasing and completely predictable. (...) Scientists collaborating with a government-financed research center are studying the impact of the technologies on marine life. A fishing group unsuccessfully went to court six years ago to block the deployment of a turbine at the center’s test site, and ran billboards with the catchphrase “Grinding Nemo.” Regulators have required Sustainable Marine to outfit its platform with a variety of underwater sensors and cameras to track sea life and to automatically lift the turbines when whales or other large creatures approach. If Sustainable Marine’s underwater sensors and cameras confirm assertions by the tidal power generation industry that fish, whales and other sea creatures will safely swim around their turbine blades and the prototype proves reliable, it may become part of a large-scale development. https://www.nytimes.com/2022/11/14/tidal-power-clean-energy-bay-fundy.html Link to comment Share on other sites More sharing options...
