NTU Singapore scientists design ’smart’ device to harvest sunlight

💡 Bright idea: Daylight can now be brought underground, thanks to #NTUsg scientists who have built a ‘smart’ device to harvest the daylight to light up underground spaces. Like a magnifying glass, the device shaped like a crystal ball focuses sunlight into one point where it is collected at the end of a fibre cable then transported to the other end that is deployed underground where the light is emitted. This reduces the need to tap on traditional energy sources for lighting. #NTUsgResearch #NTUsgInnovation #NTUsgSmartCampus #sustainability
