Kidney Cells Make Implantable Power Source

Posted by ScuttleMonkey on Mon Dec 10, 2007 01:06 PM
from the black-market-batteries dept.
Galactic_grub writes "New Scientist has an interesting round-up of patents related to green power technology. The ideas mentioned include an implantable power source made from stacks of kidney cells that could drive implanted devices like pacemakers, a chemical way to purifying hydrogen, a buckyball-based filter for methane fuel cells and an organism that turns grass cuttings (and other bio-waste) into ethanol."

        I'm not sure what a host's body rejecting an implantable device has to do with biobatteries. As you've said, rejection of the device can be deterred in other ways.

            If the biobattery will live as long as the host does, then that sounds fairly permanent.

    The faster we switch ethanol production over to cellulose, the better. It would mean that we're not cannibalizing our food supply to make it, and the cost wouldn't be tied to the rising price of corn.

    Making our ethanol out of the leftover waste materials is probably the only way ethanol will ever take off in this country.
    • I agree. I find it obscene that turning "food" into fuel is subsidised when there are starving people in the world.
    • The faster we switch ethanol production over to cellulose, the better.
      The US should switch to adipose for an almost limitless energy supply.
       
      • I find that obscene because it's basically turning, "food" into, "fuel" in a far less efficient manner than corn-derived ethanol.
        • Is it really that inefficient? They've already consumed the food. So it's already gone, why not get back a little something extra depending on how much that costs of course.
    • It would mean that we're not cannibalizing our food supply to make it,

      If corn were the most efficient way to produce ethanol then it wouldn't matter. Say for instance that hemp were legal, and it was more efficient (actually it is more efficient INMN, but bear with me here. Substitute whatever crop is MOST efficient if you care to research, which I don't).

      The land now used for growing corn would be used for growing hemp. Whether that land is used for corn, hemp, or sawgrass it's land. It doesn't matter if t
    • I wish ethanol would just go away.

      Its a hydrocarbon, just like gasoline. That means when you burn it, ethanol still puts carbon into the atmosphere. Even worse, ethanol production and distribution haven't even gotten off the ground yet and its already screwing up the economy. Corn prices are sky-high on speculation so the livestock end of agriculture has to feed their cattle, pigs, etc. other expensive grains. This is driving the price of meat and dairy up. Farmers are switching their crops over to

      • It puts carbon into the atmosphere, but the carbon was removed from the atmosphere when the feedstock was grown, so there are no net carbon dioxide emissions.
        • 1) When plants die naturally, a significant proportion of their carbon goes into terrestrial carbon sinks instead of the atmosphere. Burning plant material releases stored carbon directly into the atmosphere.

          2) As many on this board have already noted, the modern agricultural process produces a large amount of carbon so ethanol isn't going to be carbon neutral.

    • This doesn't encourage sustainable agriculture. How much ethanol will it take to produce the extra industrial fertilizers that are needed if "leftover waste materials" aren't recycled back into the soil?

    • They actually have a Biowaste Generator plant near Neshoba County I think. The idea is that with all of the pine trees they are cutting down from commercial farms, they'll take the waste bark, etc., and use it in the generator. Not sure though, and I'm not gonna waste an hour looking for the reference.

    These are all interesting and valuable technologies for extracting and using energy. But of course they all consume some of the energy they help produce and deliver. Making that delivery system less efficient in order to use it at all.

    But existing fuels have the same problem. Is there anywhere that shows how much energy is consumed by extracting petroleum from the ground, getting it to a ship or pipeline, refined into products, then across to where it's burned for power? How much gasoline is burned driving to a gas station to fill up? How about the energy required to build and maintain the infrastructure, or even explore for new fields? Some of these losses are small, but they all add up. How about for coal and natural gas?

    Once we know the "energy budget" of each kind of energy system, we can actually make sensible choices. Gasoline has some of the highest energy density of any fuel, but its pollution has extremely high energy costs to recover from. Maybe some of these other systems are better net propositions. Or maybe they just look good on TV, until you see all the costs that actually goes into using them.

      Sure, but in areas like that you're going to see a lot better returns on solar power than areas with high rainfall will. In that respect, this sort of technology will be a complement to solar power. In other words, areas with lots of rain and cloud cover will have more available biomass for fuel, whereas areas without the rainfall will see much more output from solar generators. Ideally, it should balance out, although in actual practice it will certainly be more messy than that.
