Pin It

At the University of Utah, a mechanical engineer named Mathieu Francoeur has found a slight technicality when it comes to a principle that allows wasted heat to be recycled into usable electricity. This presumably amazing device-which has been dubbed a Near-Field Radiative Heat Transfer Device-collects heat by simply placing two silicon surfaces close to one another until they're almost touching. In order to store heat, this device blows past the blackbody limit.

In the future, this setup might not only be able to cool down mobile devices like laptops and smartphones but it may also be able to channel their heat into more battery life.
