Organic Chlorophyll Battery
Jeremy Faludi, 4 Nov 08

Cool-sounding innovation in the lab, low energy-density, but cheap & non-toxic:

A scientist in Taiwan has invented the world's first chlorophyll organic battery that can supply electricity within 10 seconds of being wetted with water, beverages or even urine.

Chungpin Hovering Liao, a professor at the Graduate School of Electro-Optic and Material Science of National Formosa University in central Taiwan's Yunlin County, told a news conference Wednesday that the battery, when wetted, can provide electricity for two days to a week.

While the strength of the battery is about half that of an ordinary battery, its storage capacity is more than that of Japan's water-powered fuel cells, he said.

The production cost of the chlorophyll organic battery is very cheap -- about NT$1 to NT$2 (US$.03 to US$.06) , Liao said, adding that the battery contains no toxic substances and will not pose an environmental hazard, even if discarded at will.
