Recharge Your Batteries While you Walk

Imagine being able to charge electrical devices without having to plug them into a socket on the wall. Well that is what M2E Power are working towards. M2E Power suggest that by transforming the way energy is generated is one way in which we can reduce our reliance on electricity. There are many devices that have tried to do this in the past by harnessing solar power, and we here are Mintgadgets have blogged about many of them for example the Solio Magnesium Solar Powered Charger, the Solar Powered Headphones, or remember the Solar Powered Bluetooth headset?  However the problem has always been what happens if its not sunny? Who spends enough time outside to sufficiently charge solar powered gadgets? Well M2E’s solution is to recharge items based on kinetic energy. Basically the technology relies on strapping a device to a belt which converts the kinetic energy absorbed whilst a person moves to recharge a battery than can then be used in devices.

Currently this is just a concept and not yet available, don’t worry though as soon as we hear about its release we will let you know.
