Sugar powered batteries

Researchers at Saint Louis University in Missouri have come up with a fuel cell that can run on nearly any sugar source. It converts the sugar into electricity and potentially can create power sources that are much smaller than current lithium batteries. Converting sugar into power is not a new concept. Several years ago some scientists came up with a fuel cell idea for powering pacemakers. It was also powered by sugar. It converted the glucose in the patients blood into electric power. There have also been a few other fuel cell technologies that converted various sources of sugar into power.
The difference in this system, is that the researchers claim to be able to use any source of sugar. So you may soon be able to pour some cola into your Ipod when it runs low on power.
