“All that is required is a small supply of a sugary drink… Bio-batteries are fully biodegradable and have, on a single charge, a potential life-span three to four times longer than conventional lithium batteries.” When someone sees a quote like this, that too on a reliable news aggregator like Google, it's hard to just move on and click 'next'. According to a report in CRN.com.au, a paper on a Coca Cola-powered mobile phone was recently published by Chinese designer Daizi Zheng, the aforementioned quoter. Basically, as a part of an Eco project, the designer used the sweet soda to power a mobile phone. The claims are impressive and say that the battery can last 4 times longer, and is fully biodegradable.
