Sub-zero Refridgeration/condensor construction; suggestions? Comments?


Ok, so I would like to create a refrigerant system specifically for sub-zero degrees Celsius temperatures; the idea would be to create either ultra high efficient/dramatic condensing, a reaction requiring deprivation of energy (cooling), or condensing of a gas which boils below 0*C. All those these are my ultimate goal; I would like to buy or build a single devise or single devise (most importantly cost effective, second most important, effective, third most important is compactness. I know there is a way to manipulate cooling systems that are wildly a available and cheap to produce a well-targeted/efficient quite cool enclosure; ideally at least 50*C, and don't tell me dry ice, because dry ice will not satisfy me; it would be horribly time consuming to deal with dry ice if one were to attempt a longer term below 0*C (again, ideally variable up to -50 or lower)...

Excuse me for likely rambling, but I am not editing it, nor am I apologizing...

Any ideas as to w
How I should go about this? I have several ideas, but it would be nice to hear from someone with some degree of experience building a cooling system for below zero Celsius (like, -50 or lower most ideally)(most most ideally for very cheaply)...

Oy...well, I've got my little projects, and sometimes I haven't the time, so this one is on you - help me find the answer to this. Prove you are good for something, sciencemadness!

Garage chemist has done this and detailed it here. Search and you may find it. He managed to hit -50*C alright.
