What if machines ran off biological fuel—blood sugar—from our bodies? Could we basically power gadgets on America's increasing supply of body fat and Snickers bars?
The questions were thrown at me by our dear Brian Lam with a disclaimer of "I may have been under narcotic substances when I came up with this idea." But, despite that disclaimer, he's onto something. After all, we've looked at concept models of gadgets intended to be powered in that precise manner, by converting blood glucose into electrical current. There's also been some success in recent bio-battery research with yeast fuel cells. So, why aren't we sating both gadget lust and hunger in the same bite yet?
