Blood-powered "human batteries"

Researchers at Panasonic's Nanotechnology Research Laboratory in Japan are developing a way to draw power from blood glucose — mimicking the way the body produces energy from food. The result could be a device capable of producing electricity from blood, effectively turning bodies into "human batteries". The estimated power output per person? Around 100 watts, or enough to turn on an average lightbulb. Link, Discuss (Thanks, ESC)
