Systems that convert kinetic energy into electric energy have made great strides in recent times, from mobile phone charging bicycle dynamos to tiles that turn footsteps into electrical energy. Recently researchers at Georgia Institute of Technology have come up with what they believe is a more efficient approach – a self-charging power cell that directly converts mechanical energy to chemical energy and stores the power for release as an electrical current.
