This massive craft generates electricity. Orbital O2 2MW is a floating tidal turbine platform. Designed to combat climate change by creating clean electricity for millions of homes. It uses massive blades to capture moving currents. Currents are directed to power generating cells in order to create clean energy. Orbital says that a single O2 can generate 2.5 megawatts of power. Enough to power 1,700 U.K. homes annually. The O2 is massive, the same length as a 747 Jumbo Jet. It has 2 foldable 59 ft. long legs with 2 32.8 ft. long blades. Should this technology be everywhere?
