A supercondenser has been developed that can be charged by the sun. It contains no expensive or hazardous materials, has patents pending, and it should be fully possible to manufacture it on an industrial scale. In the future we could have a completely new type of energy storage, charged by heat energy – eg during the day when the sun shines, or by waste heat from an industrial process. The heat is converted to electricity, which can be stored until it is needed.
Simply put, a supercondenser is energy storage: a type of battery that consists of an electrolyte of ions between two electrodes. The charge is stored next to the electrodes, most often in carbon nanotubes...
