I’ve been talking to Laurence Kemball-Cook, the 26 year old technology entrepreneur Laurence Kemball-Cook. Laurence is Founder and CEO of Pavegen, an innovative clean-technology company based in London which instantly converts kinetic energy from footsteps to renewable off-grid electricity. A design engineer by background, Laurence has a passion for sustainability and the environment. He believes that disruptive technologies can build public awareness and support for renewable energy and help reduce our reliance on a grid powered by carbon-intensive fossil fuels. He is a great speaker. Here he is in action at TED Rio in 2012.
