Laurence Kemball-Cook: Energy capturing cement
Laurence is an industrial design engineer who used to work for one of Europe’s largest energy companies, but now wants to put people on the power grid by harnessing their daily expendable energy. “Imagine if your walk home in the morning could power lights for your walk home in the evening,” Laurence says. His solution? Pavegen, a flooring tile that absorbs kinetic energy from footsteps and converts it into electricity. “It’s almost like the gamification of energy saving,” he explains.
