Human Blood For Electrical Power

Posted by Zonk on from the blaah-blaah! dept.

burner writes "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 with a non-toxic substance used to draw electrons from glucose. So where should I have my laptop power port installed?"

    Its interesting, but unless you can use multiple cells or something there is not enough power to run any kind of pump. Afaik one of the major issues with any kind of artificial heart is it kills some of the cells as it pumps. Still this kind of technology is definitely interesting, and who knows what might be possible in the long term.

    Didn't slashdot report on this last year? Japanese researchers, check; using blood for energy, check...seems like a dupe, yeah.

    In any case, 0.2 milliwatts isn't exactly that much power: the AbiCor artificial heart documentation mentions that it consumes several watts from its external battery pack, a far cry from what this provides.

    Though, I can imagine a beowulf cluster of these. ;)

    In a way, you are right!! Read this from TFA

    Since the electron mediator is based on Vitamin K3, which exists in human bodies, it excels in safety and could in the future generate power from blood as an implant-type fuel cell)

    Though a bit distant, it might become possible to *fabricate* parts of bodies(not alone heart), that can be *powered* when implanted.
