ORONO, Maine — As waves grew and gusts increased, a wind turbine bobbed gently, its blades spinning with a gentle woosh. The tempest reached a crescendo with little drama other than splashing water.The demonstration featuring a 13-foot-tall floating wind turbine in an indoor pool aimed to ensure it can withstand the strain of powerful water and wind when much larger versions are deployed in the ocean.
“These structures are massive,” said Anthony Viselli, chief engineer for offshore wind technology at the university’s Advanced Composites Center, after the demonstration wrapped up. “These would be some of the largest moving structures that humankind has endeavored to create. And there would be many of them.”Global clean energy just set a record.
“This is a global problem and this is an ideal solution in order to deliver power to shore,” said Gazelle Wind Power CEO Jon Salazar. On a recent day, the semi-submersible floating turbine was tethered to the bottom of the basin. Its 1:70 scale represented a real turbine standing about 800 feet tall atop a platform in the ocean. The goal is to have industrial scale turbines of 15 to 20 megawatts each, Dagher said.
