UNSW scientists have made a significant leap forward in environmentally friendly power innovation by creating power from alleged "evening" sun-based power. The group from the School of Photovoltaic and Renewable Energy Engineering created power from heat emanating as infrared light, similarly as the Earth cools by transmitting into space around evening time. A semiconductor gadget called a thermoradiative diode, made out of materials found in night-vision goggles, was utilized to create power from the outflow of infrared light. Although how much power created at this stage is tiny — multiple times not exactly that provided by a sunlight-based charger —
