For those who have their camera's battery die on them unexpectedly, fear no more. You can soon use your blood to power your camera!
Taken from slashdot. Japanese Reasearchers develop a fuel cell that runs on blood
"Tokyo - A Japanese research team has developed a fuel cell that runs on blood without using toxic substances, opening the way for use in artificial hearts and other organs.
The biological fuel cell uses glucose, a sugar in blood, with a non-toxic substance used to draw electrons from glucose
The newly developed cell in the size of a tiny coin is able to generate 0,2 milliwatts of electricity, enough to power a device that measures blood sugar level and transmits data elsewhere, the group said"
- 0.2 milliwatts? Hmm I think you'll need to sacrifice a few ppl to generate enuff electricity for a DSLR.
