Ben Krasnow: DIY liquid nitrogen generator

You can make solid nitrogen from liquid nitrogen this way (same logic applied to the solid/liquid phase change). In order to build a normal heat pump cooling system, you need to compress a working fluid (eg helium), cool it, then move it into the insulated chamber, expand it, then move it back outside the chamber and compress it again.
