Kidney Cells Make Implantable Power Source 88
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."

He suggests that such biobatteries might be ideal for powering devices inserted in the body, such as insulin pumps or pacemakers.
So you're going to give up part of your kidney for a pacemaker or insulin pump? When they've already solved the rejection problems in far less invasive ways?

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 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).

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.

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.

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.
