Keeping Your Keg Cool Sans Ice

DrLudicrous writes "Case Western Reserve University is reporting that first year physics graduate student Adam Hunnell has come up with the idea for a Keg Wrap, a thermoelectric sheet that will be able to maintain a full keg at 32-35F by running off of wall current or even a car's cigarette lighter. The funding for this project is coming from the National Collegiate Inventors and Innovators Alliance, which has provided Mr. Hunnell with a $20,000 grant. Serious stuff - I'd rather see this than another few million dumped into quantum computing."
