;Normally microbial fuel cells (MFCs) can take as long as couple of days to start power production as the bacteria needs to get adjusted to the environment. But for this device, the power production starts within 10 seconds, that is, almost immediately,; a statement issued by the institute said.At present, the power from the device is in the range of few microwatts. It can be boosted further by stacking multiple devices which will help drive several practical applications. Unlike other heavy batteries, this device is made on a paper platform using air cathode and the anode can be prepared from any simple carbon based materials. Veerubhotla 's research paper from IITKGP 's Team Electrodes at KPIT Sparkle 2018, won the first prize and a cash award of Rs 10 lakh, the statement said.
