The world is one step closer to nighttime solar power after a breakthrough discovery by Australian scientists.University of New South Wales (UNSW) scientists have found a way to ‘catch’ energy that flows out of the earth at night.“This could mean being able to achieve the ultimate dream of renewable energy: power generation uninterrupted by the setting of the sun,” the researchers claim.So how does this sci-fi technology work – and when will it hit the market?How does nighttime solar power work?Nighttime solar taps into a “large and unused spectrum of potential power,” the research team says.Heat – which is a form of energy – flows from hot areas to cold areas.Every day, the earth absorbs heat from the sun. At night, this heat escapes the earth in the form of infrared light, and is sucked out into the icy vacuum of space.If it didn’t, the planet would quickly become far…
Solar energy that usually escapes Earth overnight can now be captured, say scientists
