Almost since the beginning of the ‘Grok, I’ve had this itch to put up "Jettiness" type posts – stuff that one ordinarily wouldn’t be pushed around by a jet engine but some enterprising young (and not so young) fools that were brave enough to ask "well, what if we do…" and then go ahead and do it.
And having fun doing it and amazing the heck of me (a guy that you never want to put a hammer, screwdriver, and saw into my hands at the same time)! While I can build castles in my mind with software, doing something that is to be hand made just is beyond me and I have great admiration for those craftsmen that can do so.
Anywho, with all of the Jettiness around here, I realized that I’ve never given a pointer to a post that says "and here’s how to make the jet engine itself" – I’ve always done what has been created around a jet engine.
Well here it is (and of course there is the obligatory warning!):
Of course, all work makes one thirst, so here’s a new kind of Jettiness – a jet powered beer cooler (again, the OBVIOUS warning applies here – don’t drink and jet (or jet make))"
And now the results.
The experiment was a complete success (apart from that PVC thing). Here is the LPG tank in water before an engine run with the beer at 11 C. The rubber cord over the tank is to stop it bobbing about in the water (as the beer cans do).
Not cold enough yet.
And here is the final result after running the engine for about 5 minutes. The engine itself will run at up to 100000 rpm with exhaust temperatures of around 500 C and noise levels in excess of 125 dBA. The beer is successfully chilled to a nice cool 2 C.
Note the temps are in Celsius.
Cool Jet!
