In London, tests are underway for glowing paving slabs that create energy simply by being stepped on. The green slabs, which contain a light that gets brighter according to how much energy is stored, are designed to ‘flex’ less that 5mm when walked over. Inventor Laurence Kemball-Cook says the patented Pavegen System slabs could be used to power anything from lighting at bus stops to ticket machines and automatic shop doors.

A paving stone on a busy street is stepped on by more than 50,000 pedestrians everyday and flexes up to 5mm each time. By creating a rubber stone fitted with secret piezo technology, Laurence has found a way of storing the kinetic energy produced. And even the rubber used on the surface of the stone is environmentally

sound - it's made from recycled truck tires.

Trials to go into several locations early next year in places such as schools and airports.
