I have a couple of questions about alternates to freon cooled air conditioning units... I've read about something called (I think) a "vortex tube", where compressed air is put into a hole; hot air comes out one end and cold comes out of the other. Can anybody explain the physics of this? Can anybody tell me how efficient it is compared to freon- driven coolers? It would seem to be a lot simpler and more reliable, assuming that it could match the efficiency... My other question is about the ROVAC, which was (I think), a conventional cooling unit except that it used air instead of freon. This was covered in Popular Science quite a bit maybe ten years ago (I was younger then), which indicated that it would be the direction automobile air conditioners would be going in the next few years (well, the Wankel (sp?) was supposed to do that, too). Can anybody tell me what sort of a state the ROVAC is in? Thanks - james c (I think) blasius ihnp4!ihuxq!dopey
