A mixture of cement and charcoal powder could enable houses to store a full day’s worth of energy in their concrete foundations. This new way of creating a supercapacitor – an alternative to batteries that can discharge energy much faster – could be incorporated into the foundations of both buildings and wind turbines. When paired with renewable energy sources, it could also someday let concrete road foundations wirelessly recharge electric vehicles as they drive along.
