...AND CHEAPER...:

This Comfy Shoe Doubles As A Footstep-Powered Wi-Fi Hotspot (Co.exist, 2/27/16)

Each time you take a step, you waste around 20 watts of power--around 20 times more than it takes to run a typical smartphone. But even though researchers have been chasing the idea of an energy-harvesting shoe since the early 20th century, long before any addiction to mobile gadgets, it's only now that it's actually feasible to turn footsteps into a power source.

A prototype shoe using new energy technology can generate enough power to charge a dead phone, via a USB port on the side of the sneaker. It can also run electronics embedded in the shoe itself, like a Wi-Fi hotspot or a tracker that could be used to located someone in lost in rubble after an earthquake.
