Power your tech with body heat – say no to chargers
Researchers with the U.S. Department of Energy and the University of California at Berkeley have recently discovered a new way of making silicon into a better thermal conductor for turning even small amounts of heat into electricity. Unfortunately, they don’t quite know why it works. No matter, though, as the finding could one day free up power outlets all over our homes by getting rid of the need for chargers.
The scientists found a way to arrange and bend silicon nanowires in a particular fashion that lets them channel heat energy far more efficiently than current thermoconductors. They believe that the new method might be efficient enough to be able to charge the batteries in small technology.
Imagine a cell phone or iPod which will always work, simply because it’s stored in your pocket. This might even be an end to battery meters.
