Pavegen Systems is a technology company that has developed paving slabs to convert energy from people's footsteps into electrical power. The slabs were installed at the London 2012 Olympic Games at West Ham tube station.[1] Pavegen have received significant media exposure their innovation and has been featured on the homepage of the CNN.com website.[2]
Power is generated when a footfall compresses the slab by approximately 5 mm (0.2 in). The exact technology by which it functions is not disclosed by Pavegen. Pavegen uses what it calls a hybrid black box technology to convert the energy of a footstep into electricity, with a hybrid solution of mechanisms that include the piezoelectric effect and induction, which uses copper coils and magnets. The power thus generated can be used to run low-voltage equipment such as streetlights and vending machines. A typical tile is made of recycled polymer, with the top surface made from recycled truck tires.
According to Pavegen, each step produces enough power to light an LED-powered street lamp for 30 seconds.[2] Pavegen was developed by Laurence Kemball-Cook who is the founder and CEO of the company. Laurence has done 3 TED talks, including at TED Active in Palm Springs,[3] March 2012 and London, April 2012 and Rio de Janerio at the Rio+20 Climate summit on behalf of the United Nations.[4] In April, 2013 a demonstration installation harvested energy from the runners in the Paris Marathon.[5]
