Remember how the robots in the matrix harvested people for energy? Well – why not do that ourselves? Apparently, turning our bodies into portable batteries isn’t that far-fetched of an idea:
[T]he bio-batteries closest to reality at this time, the yeast cell ones, have a major problem with waste products. That waste is created as those particular batteries involve microbial yeast-based fuel cells that steal “some of the electrons produced when the yeast metabolizes glucose” in order to create a small current. While the entire process works just fine, the yeast cells are at risk unless the waste products are removed. We can’t exactly let the waste be dumped into the blood stream, so until there’s a some kind of cleaning process, the batteries are trouble as they either they die off or poison your bloodstream while trying to survive.
People are already dreaming up gadgets that could, say, use your blood to power a digital tattoo. Who needs an iPhone when you’ve got a blood powered tattoo on your arm?
Anyway, this is from a cool blog I haven’t seen before – This Cyborg Life. Read up on people choosing to amputate in order to receive prosthetics (sometimes there’s a good reason).
