A novel research by scientists at IIT-Kharagpur has shown the way to generate electricity from onion peel. Eateries saddled with bags of the waste product can now turn them into a power source - the skin of a single onion can light up 12 green LEDs.
The researchers have applied for a patent on the technology which can be used in places where onions are used in bulk. "The technology can be easily adopted at restaurants where a lot of onion peels are accumulated on a daily basis. Only, they end up in bins," said Khatua.
His research found that only half-an-inch of an onion peel is enough to generate 20 volts. "If you gather the peels of six onions and place them in a series, they can light-up 80 LEDs or charge your laptop or mobile phone," the scientist said.
