Liquid Nitrogen Generator - Overview

This liquid nitrogen generator uses a Stirling-cycle cryocooler that was pulled from a cellular phone tower.  It was used to cool a superconducting RF filter that aids cell communications.  The cryocooler is able to pump enough heat away from its cold end that air will liquify and drip into a vacuum flask for storage.
