Human Power For Human Upgrades 23

Dozix007 writes "The human body, like any other machine requires energy to operate. However, during operation we release residual heat which can be used for power. Many people who rely on pacemakers and other artifical devices in their bodies may recieve 'upgrades' to avert the many surgeries per. year to replace dead and dying batteries. Not quite the Matrix yet, but we are getting there."

    This is a dupe from a couple days ago... still a semi-interesting read if you missed it.
  • How this is related to Matrix?

    (I have seen only the first movie).
  • ... the person with this technology in them spontaneously combusts?
  • Although we generate heat, on a microscopic level, our bodies need more energy put in that it can give out. All the food you eat requires energy put in to be produced and we get that energy out of the food. If any significant portion of that energy were drained, our bodies would have problems and eventually shut down. The heat from our bodies is generated collectively from individual cellular mitochondria.

      "Although we generate heat, on a microscopic level, our bodies need more energy put in that it can give out."

      Duh! Its amazing how often people speak of the second law of thermodynamics: In order to keep the entropy of our bodies constant heat must be rejected from the system (it is a machine operating in a cycle after all) and no conversion of energy from one form to another on a macroscopic scale can be 100% efficient unless the second form is heat.
    • Yes, yes, and this is why, fundamentally, the Matrix doesn't really make sense.

      But I really doubt the 100 microwatts of power they are trying for will be significant enough to be noticed--your body gives off about 100 watts of radiation as it is.

    • Seated and at rest the body produces about 400 Btus per hour of excess heat [ufl.edu] which must be transferred to the environment. In contrast, climbing a steep set of stairs produces an excess of 4,400 Btus per hour. Since humans are warm-blooded mammals, the body needs to lose this excess heat because deep body temperatures must remain relatively constant at 98.6 F to prevent serious medical complications.

      That doesn't sound right to me, I thought deep body temperatures were more like 100 F and that 98.6 was just an orifice temperature. But that aside, the point is that generally speaking we produce more heat than we need. This is true except when the ambient temperature drops below a certain point, of course, but in general we're radiating heat like crazy. It only makes sense to make use of this heat loss when possible.

      • ...but in general we're radiating heat like crazy. It only makes sense to make use of this heat loss when possible.

        Well, since majority of the body heat is released through the head, it will make for some interesting contraptions... :-)
      • Sure, it's a great idea to make use of the excess heat in our bodies somehow, maybe a hat that charges your cell phone.
        But that heat ultimately is paid for, in the form of groceries.
        The point is, you could not farm the radiant energy of off humans, because you would expend more energy keeping them alive.

    Why does this idea of body-generated electricity conjure up images of weary airport travelers sitting in cheap plastic chairs, power cords running from their laptops up their legs, connecting to heat collecting anal probes, charging said laptops for yet another round of Whack-a-Mole, business style?

    Oy, and I thought the world was a strange place already.

      Because you're a strange, sick little man.

  • ...although you have to wonder what happens if something breaks. Doesn't the human heart use electrical pulses to actuate it's muscles? What happens if the person wearing this gets electrocuted by an outside source?

    • What happens if the person wearing this gets electrocuted by an outside source?

      It would be bad, of course, but it wouldn't have anything to do with the topic under discussion. The heat source that powers a generator doesn't have an electrical connection to the generator.
