A new and blooming amazing device that can harness energy from rivers and oceans could power the whole world, according to scientists.
The technology, inspired by how fish swim, can generate power in water flowing at as slow a rate as one knot, whereas mills and turbines need an average current of five or six to work efficiently. Most of the earth's currents are slower than three knots, the Daily Telegraph reports.
The system, which was conceived by boffins at the University of Michigan, is called Vivace - vortex-induced vibrations for aquatic clean energy. Vivace would also be less harmful to aquatic life than turbines and mills, and would operate far enough below the water's surface that it would not interfere with ships, oil rigs and that kind of malarkey.
Professor Michael Bernitsas says: "If we could harness 0.1 per cent of the energy in the ocean, we could support the energy needs of 15 billion people."
Flippin' Henry!
