SINGAPORE: What looks like a crystal ball in a transparent glass case could soon be used to light up underground spaces in a sustainable way.
Concurrently, small motors - assisted by computer chips - automatically adjust the position of the fibre’s collecting end. This allows the device to optimise the amount of sunlight that can be received and transported as the sun moves. Researchers believe the device is ideally suited to be mounted as a conventional lamp post above ground.
The qualities of the light output of the NTU device is also “comparable” with current commercially available daylight harvesting systems that are more costly, said the university.
