Meet the clean-tech CEO who compares his company to Apple and Tesla

Laurence Kemball-Cook is the CEO of Pavegen, a clean-technology business which harnesses energy from human movement. His main product is a paving slab that generates energy when people walk over it.

The 30-year-old British CEO told Business Insider that he's just signed a deal with the US government to install energy-generating paving slabs in Dupont Circle, near the White House in Washington D.C, where he says he will be meeting Obama for the second time later this year.

Another of Pavegen's installations can be found under a soccer pitch in a favela in Rio De Janeiro, which uses a combination of kinetic and solar energy to power floodlights.

Pavegen is now six-years-old. However, on the May 11, the company will announce a "full rebrand ... the difference will be like a comparison between a car and a super-hover-jet-motorbike."

Business Insider had a chat with Kemball-Cook at the Millennial 2020 conference in London, to find out more about the clean-tech start-up.
