Scientists Find a Way to Harvest Clean Energy From Nothing But Air : ScienceAlert
Engineers have demonstrated something marvelous. Almost any material can be used to create a device that continuously harvests energy from humid air.It's not a development that's ready for practical application, but it does, its creators say, transcend some of the limitations of other harvesters. All the material needs is to be pocked with nanopores less than 100 nanometers in diameter. That's around a thousandth of the width of a human hair, so easier said than done but far simpler than expected.Such material can…
