PeltierBeer
Helstein writes "Finishing a beer in the sun before it gets warm is usually not a problem, but what about those really hot days? Having some hardware lying around there is only one solution to keep the beer cool, that's to make a PeltierBeer."
See also the jet-powered beer cooler.
Why do I remember that? <sigh>
Note, IE. Ireland. The real stuff.

Hi, MacDork. Yes, your understanding of thermodynamics is probably ok. It's your ability to read the article and grok it that's coming up short.
He used a Peltier junction. Look it up. It's an active, solid-state, heat transfer device. It can move heat against the thermal gradient, when supplied with power.
IOW, run current through a Peltier and one side gets colder than ambient, and the other side gets warmer. Reverse the current, reverse the effect. Add a fan to the hot side to get rid of the heat, because they are limited to a max temp differential between the sides.
Ce n'est pas un vrai mouvement de robot!
Ales in the british tradition are typically served at "cellar" temps -- around 55F-60F. Continental lagers are best a little colder but generally not below 45F. A few belgian styles do better even colder, but never ice cold (38-45F).
If served ice cold, beer tends to lose most of it's flavor and seems thinner. The same is also true to a lesser extent with increasing carbonation. In the case of an american pilsener like bud, you're not missing much if the beer is ice cold. In the case of a fine czech pilsener like Budvar, you'd be missing a lot.
