Down to around 20-30 watts of heat lift at -147C (the critical point of nitrogen), so it looks like I'll be making some LN2 in the near future with the mixed-gas joule-thomson system. As a slightly easier test, i managed to liquify a little bit of methane from my natural gas line (highlighted in red), which is at -162C at 1 atmosphere of pressure. A lot of it boils off, so some extra heat exchangers are gonna need to be used to capture the cooling energy of the boiloff gas. For the video-after-next I'm planning to make some more liquid and then freeze it under vacuum (-182C).
