Wind power, solar power, and now shoe power.

It sounds like a genuinely simple and brilliant idea. I hope it is. Pavegen are a company that have developed paving slabs that convert the kinetic energy from footfall into electricity. So it lets people ’save energy without realising it’. Unless it is unfeasibly exhaustive on the environment to produce, then it sounds like a winner. Maybe they could come up with roads that convert the movement of vehicles into electricity also? And tube tracks?
