Biotech Power The Matrix Hardware

Electrical Power From Humans 220

Posted by Soulskill from the don't-give-them-any-ideas dept.
Coisiche writes "The BBC covers a team of scientists who are working on a new way to power medical implants: an internal biofuel cell. From the article: 'Their gadget, called a biofuel cell, uses glucose and oxygen at concentrations found in the body to generate electricity. They are the first group in the world to demonstrate their device working while implanted in a living animal. If all goes to plan, within a decade or two, biofuel cells may be used to power a range of medical implants, from sensors and drug delivery devices to entire artificial organs. All you'll need to do to power them up is eat a candy bar, or drink a coke. ... In 2010, they tested their fuel cell in a rat for 40 days and reported that it worked flawlessly, producing a steady electrical current throughout, with no noticeable side effects on the rat's behavior or physiology.' Of course, there's never been a sci-fi movie using such technology as a plot device..."

        This is all fine and dandy, but my gut feeling is that some very simple physics and biology related problems are going to limit these things to little more than low output power supplies for simple implants and novelty bodymods.

    It seems like the usage of your body's energy is a feature, not just a cost. Would it be possible to have some device use as much energy from your body as possible so as to keep you from getting fat? And for a triple-play, how about if that energy could also be stored or transmitted for consumer use, displacing some of your expenditures on electricity?

    Obviously, by that point the logistics would be a major issue, but it would be awesome if something could tackle the problems of implant powering, obesity, and energy all at once.

My suggestion was for the device to siphon off glucose your body would normally pass through its regular metabolic channels (and thus store as fat); DNP had numerous effects in addition to simply consuming energy. A device that coverts it into electricity could just turn the glucose into harmless smaller compounds like water and CO2.
