Let's face it. The globe is getting warmer. Everywhere we turn or everything we use is also getting way way much hotter. Mobile phones, microwaves, laptops, escalator handrails. All these generate heat in an increasingly heated world.
So, it is actually about time for someone to come up with an idea on using these numerous sources of heat. Like using it to charge electronics while being on the move perhaps.
Meet the EcoCharge. Drawing heat from any well, source of heat, it has some internal thingys that convert heat to electricity which is zapped out via a USB connection. Also, it comes with magnets its sides, so it makes it way much easier to leave it attached to a metal surface for maximum heat transfusion. It also displays the efficiency of your charge. I mean, what else could you ask for?
