Human Blood For Electrical Power

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?"

      Personally, though, I think it would have been cooler if the machines were using us as inexpensive processing units. What if, in the real world, you didn't actually have to sleep, and that 'sleep' is the machines using you to think? o.o

      Actually, humans wouldn't have to sleep for the machines to use them for processing - large parts of neural systems were unused.
      No they aren't, that whole "humans only use 80% of their capacities" urban legend is bullshit, neural system structures are quite heavily specialized and although all of them aren't used 100% of the time there is no such thing as a "waste" in the neural system, nearly everything has a role, and what doesn't used to or may have one in the future.

      Why go to the gym? You don't just burn calories. You strengthen your muscles and help the cardiovascular system. I suppose the second one would be taken care of by this plug, because the heart doesn't care where the blood is going, only that it's going and needs to be replentished. But other muscles would not benefit at all from this. But the problem is even deeper than this. A significant drain on blood energy would seriously fuck with your body. Would you release endorphines from this? Would your body know to get out of breath? Would your heart rate increase? I dunno... it could be dangerous.

    Hypoglycemia would indeed be a concern. However, the possibilities are intriguing for Type 2 diabetics, who are usually insulin resistant and have way too much glucose in their blood. If a fuel cell can use up that extra glucose, they might actually be able to make a device that would monitor, record, and lower the blood glucose level to normal or thereabouts. Imagine, diabetics could actually wind up producing more power than they use...

    The electrons don't just vanish.
    If they did, the energy released would probably turn us into miniature suns the moment we turned one of these on.

    It's more likely that the now unstable glucose molecules will break down into carbon dioxide and urea, consuming some oxygen in the process, much like it does when consumed by a normal cell. One presumes the spent potential from the electrons will result in the electrons returning to the blood stream.

    And yeah, pushing this too hard would probably fairly easily kill the user, (read, a laptop at 60-100Watts? i doubt it. maybe a trickle charger for the battery :) ).
    A well controlled system could easily result in an acceptable increase in energy consumption, which would result in weight loss, without actually exercising (also, not a good thing, since the muscles aren't going to develop, but the fat will be consumed, leaving the user with no way to keep warm). One presumes that anyone using a device like this would be on a strict high-glucose intake diet.

    of course, this is conjecture, i've only done basic biology and chemistry :)

  20. glucose monitor by bodrell · · Score: 4, Interesting
    I've got mod points today, but so far no one has said much of interest on this topic. The best use of this device would be monitors for blood sugar levels, to be transmitted to an insulin pump. Having an implanted glucose monitor would remove all the guesswork from insulin administration.

    Note: I'm not saying that the device would lower glucose levels by consuming glucose, but since it is powered by sugar, the current should be proportional to the amount of sugar. If blood sugar is high, the implant's signal is high, and the pump delivers more insulin. No real logic required. That's why it's such a good fit. And they say so in the article:

    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.

      I was wondering about doing it the other way round. What if it could scale up to something that could reduce the glucose levels in the blood? This would be a type of cure for diabetes - both monitoring the blood sugar levels and then reducing them when they get too high. Keeping the glucose level in the right band isn't a complete fix but it would prevent any collapse or coma.

      My first thought was shame hypoglycemics won't be able to use it, but then if it is only generating 0.2mw its hard to say just how much glucose it will use. Probably not much.
