Geeks create shoe that can charge a phone while walking.

Most of us will have been caught out when our smartphone runs out of battery at the worst moment.

But soon, taking a walk could solve this problem thanks to the development of an insole that converts steps into electricity.

The Sole Power Ensoles claim to provide two-and-a-half hours of phone charge from a one-hour walk - and they could soon be sold in shops.The insoles are in the development stage so they can fit into normal everyday shoes.
They connect to a power pack fitted outside the show, and collects kinetic energy using a mechanism that converts linear motion - generated while walking - into rotational motion, which is capable of spinning a generator.

This shoes would be much appreciated in Asia and Africa when they finally come out for commercial sale as the Power situation there is not hundred percent.
