Well, you actually can.
A London-based company called Pavegen has created a tile (or energy-generating paver, is how I’m guessing the company name came to be) that creates and stores energy by simply walking (or dancing) on it.
The company deployed a 6-tile array of their tiles at a UK music festival and charged over 1100 mobile phones in one weekend, just by dancing.
The pavers (or tiles) could be placed in high-traffic areas such as train stations, malls, office buildings, and the like to power nearby lights, electronic signs, and more.
As a matter of fact, Pavegen tiles will be installed at a mall near the site of this summer’s London Olympics that will create enough energy to power half of the malls’ outdoor lights.
