Jet engine and beer

Recommended Posts

This was on slashdot a while ago, and at the time it occured to me how silly it was.

The jet engine has absolutely NOTHING to do with the actual cooling of the beer. The beer is cooled by rapidly allowing propane gas to blow out of a tank. The Liquid gas turning to - well, gas - requires heat, which it obtains from its imediate surroundings, in this case a cooler full of water and beer. Simple highschool physics.

The only purpose of the jet engine is to burn off the escaping propane.

It seems to me, that it'd be a whole lot more fun to do the same thing with a tank of nitrous oxide - aka laughing gas. Or helium, and have a whole room of people talking like Donald Duck.

While I can certainly appriciate new ways to rapidly cool beer, using propane and a jet engine seems prohibitively expensive, complex, and dangerous. Replace the propane tank with one containing less dangerous and more fun gas, and I'm all there.

I think you kind of missed the point. The guy cooled his beer, built a small jet engine, and most importantly he had FUN. I'm goint out on a limb here, but I don't think it was ever his intention to have this thing be efficient, or be in widespread use.

Nah, I think I understand just fine.

Any self respecting geek considers efficiency in their designs. Like this guy, who built himself a linux based "auto-bar" - complete with touchscreen... now THAT is cool. http://www3.hmc.edu/~bgreer/barmonkey/ Silly, fun, practical, and effecient. Plus, it mixes your drinks.

My point, was that the jet engine was COMPLETELY useless to the cooling of the beer. To say that he "cooled the beer with a jet engine" is entirely false. He cooled the beer with a tank of compressed gas.

Now if he'd actually cooled it with a turbine - I'd be REALLY impressed. It wouldn't be that hard, drive a piston off the fan, attaching the piston to a compressor on a freon based refrigeration unit, and see how quick you can spin it, for example.

Simply using a turbine to burn off extra gas, in my book, is not a cool hack.

you could always use just the jet engine powered by the prpane, to power with beed air frm the engine a nice expansion turbine to rrapidly expand the air thus cooling it and use that air to cool the beer.....and then ya stiil could use the engine to power something lke a go cart to scoot ya around the football game parkinglot!!!

I tink wingnut's onto something...You could use the jet-engine to power a go-cart, and have cold beer by the time you reach your destination.B|

This is kind of like strapping a can of food (with a nail hole punched in it) to your tailpipe & driving somewhere & getting a hot lunch.

What a waste of all that energy. I say use it to set up a mobile wind tunnel like skymonkeyone described in the wingsuit forum. Now that would be both fun AND NIG NOGGEROUS!;)

Why are you being so irritable? That's my job.

Was on Slashdot, and on REH42 before they folded.

Touted as a beer cooler, true, but I think the nifty part is owning your own jet engine.

The Green Mamba was for sale last year... :D

Joule Thompson cooling people, it was here last year......

In essence the jet is just there to safely dispose of the depressurised gas....

Ah at long last, now that is much more practical!
