Kidney Cells Make Implantable Power Source

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."

These people have been starving since long before I was born, so no, I don't have to take responsibility for it.

The area they live in hasn't been arable since before the industrial revolution, so no, my society doesn't need to take responsibility for it.

The people who aren't feeding themselves either aren't capable, in which case they aren't viable people, or aren't willing, in which case they aren't viable people. The trash heap of history welcomes them.
