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."

Proper Ethanol

[Swordopolis]

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.
