In an interesting twist in emerging technologies and the energy sector, a team of researchers from the National University of Singapore (NUS) has created a device called the Shadow-Effect Energy Generator. The device is able to create an electrical charge using the contrast between shadow and light.
It sounds like something out of a science-fiction novel, Yahoo News reports that the team behind the device capitalised on the illumination contrast caused by shadows as an indirect source of power.
“The contrast in illumination induces a voltage difference between the shadowed and illuminated sections, resulting in an electric current. This novel concept of harvesting energy in the presence of shadows is unprecedented,” says research team leader, Assistant Professor Tan Swee Ching, from the NUS Department of Materials Science and Engineering.
Based on laboratory experiments, the harvested energy from the device in the presence of shadows created under indoor lighting conditions is sufficient to charge a smartwatch at 1.2 volts.
The NUS team’s research breakthrough was reported in the scientific journal Energy & Environmental Science on 15 April.
