A team of researchers at Singapore’s Nanyang Technological University has designed a “smart” device to harvest daylight and relay it to underground spaces, Tech Xplore reports. Authorities in Singapore are looking at digging deeper underground to create space for infrastructure, storage, and utilities, so demand for round-the-clock underground lighting is expected to rise. The scientists used an off-the-shelf acrylic ball, a single plastic optical fibre, and computer chip-assisted motors.
