Sony Japan has just posted a short video and press release detailing its latest fuel cell - a device that uses not ethanol or methanol this time, but glucose extracted from grape juice and sports drinks.
The four-cell array can be seen powering speakers attached to a Network Walkman after being filled with a squirt of grape extract and a small fan using the sugar in a Gatorade-type sports drink.
According to the release, enzymes from the labs of Kyoto University’s agriculture department break down the glucose, allowing the Bio Battery - as they’ve dubbed it - to generate a world record 50mW of power.
So, let’s see - carry around combustible alcohol for our future fuel cells or share a splash of Gatorade with the gadgets? Hmm…
Check out the vid for yourself and the (Japanese) release at the link below.
