Researchers at the University of Waterloo have developed an inexpensive device that generates enough electricity to power a calculator using only waste walnut shells and drops of water.
The coin-sized device – known as a water-induced electric generator (WEG) – produces electrical energy as water evaporates from a complex network of pores that make up the shell structure.
“It all happens with nothing more than a single droplet of water and the shell’s natural architecture, no crushing, soaking or complex processing needed,” said Nazmul Hossain, a Waterloo PhD student in mechanical and mechatronics engineering. “It’s a simple, yet powerful example of turning waste into clean energy using nature’s own power.”
