Researchers at Saint Louis university have developed a fuel cell battery that runs on sugar and will potentially last three to four times longer then conventional Li-Ion battery. And the source of sugar can be solutions of table sugar, glucose, flat sodas, sweetened drink mixes and tree sap. The battery can even run on carbonated drinks (Coca-Cola ?!), although carbonation makes the fuel cell less effective.
For now, leader of the project, Shelley Minteer, Ph.D., an electrochemist at Saint Louis University, has been able to make a small prototype battery (about the size of a postage stamp) to run a handheld calculator and it worked.
The battery contains the enzymes that convert fuel – sugar – into electricity, leaving behind mainly water as a byproduct. All parts of it are biodegradable.
If everything goes well, the sugar fuel cell battery can be commercialized within next 3-5 years.
And it’s good that University issued this press release not on Sunday, or I would have considered it to be an April Fools joke
