New Delhi: Researchers at the National University of Singapore have conducted a study to reach a conclusion on how electricity can be produced from the shadows.
A team from NUS Materials Science and Engineering and NUS Physics created a device called a shadow-effect energy generator (SEG) that uses the contrast in lighting to harvest electricity between the lit and shadowed areas.
The energy generator for the shadow effect is a low-cost tool. It was used to operate on two things – one involves converting illumination contrast from partial shadow castings into electricity and the other serves as a self-powered proximity sensor for monitoring passing objects, the study said.
The study published at pubs.org shows that SEG performs 200 per cent better than commercial silicon solar cells under the effects of shadows.
The energy collected from the SEG device can, in fact, drive an electronic watch, it said.
