Another day, another fuel cell milestone. This time, it's sugar at the bio-electrical base. Unfortunately, the world's highest output they're touting is just 50mW per cell. Still, if you daisy chain a few together then you've got enough juice (literally) to power a modern Walkman albeit, from a battery roughly 10x the size of the player. Be sure to check their video after the break -- produced with just enough hair-porn-era synth music to make the otherwise benign experience, painful.
