It would take at least WWIII. In the meantime, we already know that we could go out and acquire a small liquid nitrogen plant and make our own. (We have a powerful backup generator, which I had installed this year, that could power it.) That would cost about twice as much, which is why we haven't already bought one. <span style='color:#1F497D'>…</span><o:p></o:p></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>This comment has me wondering about the cheapest home-based liquid air making setup we could build. It wouldn’t be for cryonics, but rather for experimentation and freezing skin problems, that sorta thing. I don’t need much. I can imagine taking an ordinary compressor, filling a detachable tank to about 200 psi, immerse the whole tank in a trash can filled with icy brine, which will take us down to about -20C, then get on down to liquid air temperature with decompression.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Hey cool I remember how to do the entropy calculations to figure out if that scheme would work to make a little bit of liquid air.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>spike<o:p></o:p></span></p></div></div></div></div></div></div></div></div></body></html>
