Cool a Guinness to 2°C with a jet engine
keywords: beer, jet engines, homeowner-insurance
This article isn't new but Hackaday dug it up and it fits in with my interests. This guy in New Zealand wants to cool down his Guinness (you must capitalize it) as fast as possible and possibly die while doing it. The theory is that when a compressed gas expands from liquid to gas it draws a lot of heat energy out with it, cooling down the surroundings. He plans to release an entire tank of propane in a few short minutes, but instead of just dangerously releasing the gas into his garage, he's dangerously burning it off with a jet engine made out of a car's turbo turbine. Me? I would have just used a refrigerator, but no one would want to read about that.
