Keeping Your Keg Cool Sans Ice 315

Posted by michael from the technology-you-can-use dept.
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."

        If it has to be ice-cold to be palatable, you probably shouldn't be drinking it. :-P Fat Tire [newbelgium.com] is just one example (out of hundreds) of a beer that's much more interesting when it's served in the mid-40s to low 50s. Your average Budmilloors swill, at those temperatures, would be just plain nasty.
