U.K. switches on giant floating power plant with twin turbines

The O2 turbine, located off the Orkney Islands, generates 2 megawatts of electricity for the UK grid. Comparable in size to a Boeing 747, it weighs 680 metric tons and can be easily moved by tug boats. The turbine's blades, supported by hydraulic hinges, harness the dense seawater to produce power for 2000 homes annually. Tidal systems like the O2 offer predictable energy compared to wind and solar, with easy maintenance access due to its innovative design.
