UK-based company Gravitricity has been testing a prototype gravity battery in the port of Leith, near Edinburgh. It is a 15-metre-high steel tower, which uses solar-powered motors to hoist two 25-tonne weights on steel cables. When the weights are lowered the motors become generators and release electricity.
