With a blood battery behind it, I could add a GPS tracker and transmitter, thereby answering the question: what *does* that cat get up to during the day?

      With cows or other large animals, larger devices with more power would be possible. Perhaps a device to summon the cows for round up, or give them a shock if they stray out of bounds.

      Probably not. Your body doesn't burn fructose specifically, it converts it to glucose first. Sucrose is a fructose molecule + a glucose molecule, so it'd have to be broken apart and the fructose converted. Your body does this all automatically, but then the point is moot, since it can (technically) run off starch as well, starch just being a polysacharide of glucose.

      So in your body = okay, dumping the nanomachines into a vat of fructose wouldn't work.

      I'm not a biochemist either, but this website [rpi.edu] shows the basic Glycolysis reactions and their output.

      Basically, in this process Glucose + ATP is broken down into glucose-6-phosphate + ADP, giving off a net reaction of energy.

      Without knowing the the reactions in the process that Dr. Eda et. al. have developed, I can only guess that the oxidized glucose will combine with the some other ions (such as a phosphate) and become waste products just liek any other in the body. I'm not really sure what happens to the glucose-6-phosphatea after Glycolysis.

        Actually the reaction you describe is not very efficient and only gives a net gain of 2 ATP ( adenosine tri phosphate)per glucose molecule which the bodies tissues use for energy.

        Glucose + 2 ADP + 2 NAD+ + 2 Pi -----> 2 Pyruvate + 2 ATP + 2 NADH + 2 H+

        Most of the bodies energy is generated by the Krebs ( Citric Acid ) cycle in the mitochondria which generates much more ATP. The glucose-6-phosphate gets converted to pyruvate and enters the krebs cycle. show here [ucsd.edu] This give a net gain of 30 moles atp per 2 moles of pyruvate.

      Your body produces the bulk of its energy by converting glucose to ATP by a process known as chemiosmosis [winterwren.com] (electron transport). It takes advantage of the loosly-bound electrons in glucose, and at one point during the reaction the electrons flow along the inner membranes of your cells' mitochondria.

      The process the researchers have come up with probably uses the same effect to produce a current. The waste product? Urine. The same thing you'd produce if you metabolized the glucose yourself.

      This could be both a good thing and a bad thing. Firstly it will obviously save lives due to the pure fact of weight loss but will it replace exercise? I've done a lot of running this summer, partially it was to lose about 15 pounds I put on over classes. Now even with those extra 15 pounds I was not what anybody would classify as fat but I was out of shape and found the extra weight was slowing me down. Either way I haven't lost all that extra weight but I don't really care as I have really improved my conditioning (though not to the level of the previous summer when I did a fair amount of running as well). Either way my concern is that this will take away these peoples major stimulus for exercise by making them feel healthy with their smaller cross-section when they are in just as bad shape as before except for a reduced risk of heart disease and maybe fewer joint problems. Also if you consider anorexics(sp?!?) already what will happen when they can do it much more easily and conveniently with one of these devices/technologies I can see this as a huge problem when people run their bodies energy supplies into the ground with the touch of a dial in the pursuit of a pencil thin waist and end up starving to death while on a seemingly healthy diet.

    There are already a lot of implantable devices for which power is a big concern. From simple things like pacemakers and sensors to more complex and experimental devices like artificial hearts, everything needs juice. One of the big problems, for instance, with some early devices is that in order to add more juice you had two bad options:

    1. Have some sort of actual device sticking out of the body. This is bad, because it breaches the skin, our natural defensive screen, and such things tend to become very easily infected.

    2. Surgery to replace cells. Again, any surgery at all is going to be both expensive and risk prone.


    More recently, a third option has become available: having fully implanted power system that can be recharged wirelessly, via em radiation of some kind (you can google for it). This is a big gain, because it allows devices that are more power hungry while still maintaining the benefits of not breaching the skin and not needing frequent operations. But it still requires people to remember and have access to the appropriate charging device consistantly. If for any reason some one forgets or can't recharge, the device may shut down, sometimes with fatal results. So having a way to remove one more step for powering these things should really help improve the quality of life for a lot of people today.

    Of course, personally I find this to be a very exciting development for future things as well. When we get to the point of having more optional implants, for things like boosting hearing or vision, a way to power them will be necessary, and if the power requirements are low, then this system would be perfect. Ultimately, widespread adoption of anything, from an OS to a vehicle, is all about making it as easy and intuitive for end users as possible. There is a lot of interesting stuff going on for advanced things like brain-computer interfaces, and people who are interested should look around, as the state of the art has advanced a great deal in the past 5 years.

It would let people use just enough to live in the Matrix and take the rest. Sort of a giant SETI@home type system. Disconnect enough people and you'd have the Matrix singing "Daisy" before long.

  • I wonder if this could replace dieting as a new drug to lose weight. All you need are some nanomachines that run on this and use up the excess energy. They could putter around your bloodstream cleaning plaque from your arteries and fixing that whole "heart murmur from being so obese" thing, all while burning more calories than you would excercising.

    Or, for those of us that are more concerned with being weak & a bit chubby (rather than dangerously obese), they could build muscle tissue (easiest way I'

    I can see the jokes already:

    How many airplane pilots does it take to power a laptop?
    None. The use of laptops and other portable electronic devices is strictly prohibited during take-off and landing, acording to FAA regulations.

    How many MIT students does it take to power a laptop?
    Ten. One to blood power it while the others project a more efficient system.

    How many Peta members does it take to power a laptop?
    Two. One to power it and another to make sure they're not using the blood of any animal.

    How many quantum mechanicians does it take to power a laptop ?
    They can't. If they know where the power cord is, they cannot locate the plug. (BTW, where in the body would a power plug fit?)

    How many Heisenbergs does it take to power a laptop?
    If you know the number, you don't know where the laptop is.

    How many women does it take to power a laptop?
    No way. It's a man's job.

    How many amish people does it take to power a laptop?
    None. Amish people don't believe in Laptops.

    How many Sysadmins does it take to power a laptop?
    I'm sorry, that's a hardware issue and we can't help you with it. You'll have to get a hardware tech to power it. Good luck.

    OK, as many (perhaps to many) of you have pointed out, using enough glucose out of the human bloodstream to get 100W would be a bad thing(tm). However, the story isn't talking about taking 100W from the bloodstream, its talking about making devices that can transform glucose from many sources into electrictity. One of the mentioned applications is sugar-powered robots, in this situation it wouldn't be a problem to draw 100W, also let's not forget about larger than human sized animals. You probably wouldn't be nice if you got 100W even from an elephant, but slightly smaller amounts of power should be ok.

    Most importantly, the whole laptop thing is a joke, this is not intended to power a laptop people. If used inside the human body, this would be to power nanomachiens (almost no power drain) and medical implants (which don't draw huge amounts of power either).

    I wish I had the money to patent these ideas. Instead I will disclose them so the whole world can use them if no one already filed a patent.

    This is the cure for diabetes(sp?) as its an insulin replacement. It can keep the bloodstream below a certain glucose level with the greatest of ease, just burning off power doing something dumb (or useful, it doesn't matter). Just implant a device or series of devices that detect gluecose levels, and the device(s) stays idle or working in a low power mode until levels reach a certain level, then they burn off that excess gluecose until the blood is reduced to an optimal level. This is probably controlled by a slightly more complicated algorithm, but this should get the idea out.

    It also is a GREAT and I do mean GREAT wieght loss aid. It can use up excess energy that the body takes in sending the body into ketosis, thereby getting the Atkins type diet, while eating whatever you want. There is also studies that show if you eat at "starvation" levels your whole life (when ketosis should be happening rather constantly) you increase your lifespan by 20% or more. Therefore, this is also an anti-aging device while being a near perfect diet.

    The diet application does not require going into ketosis. It could just use much of the gluecose, thereby making it as if the person ate a smaller meal.

    This should be improved to use fats and lactose etc from the blood as well. I dont mind driving a small car powered by myself which is powered by Burger King. You get to eat all you can and you get to lose weight while speeding. I think I'll start a trucking company.
