A paving slab that generates piezoelectricity from the applied mechanical stress of every footfall on it is being marketed in London. The closely guarded technology can provide clean power and is made primarily from used tires and concrete.
The invention is the brainchild of industrial engineering graduate Laurence Kemball-Cook, who came up with the idea, perfected it in his final year at Loughborough University in central England, patented it, set up his company Pavegen and is now busy taking it to the world.
