Another great video. The coefficient of performance discussion brought back fond memories of using pulse tube cryocoolers in grad school. 8 kW compressor... ~40 W of cooling at ~50 K, and ~1 W at ~4 K, using helium as the refrigerant. We used an ADR to get down to 50 mK from there. Fun topic!

Thanks for the video and starting a discussion on the topic! Tech like LLMs can be powerful in expert hands who have the context in which to couch responses and act accordingly. But I worry about forging tomorrow's experts when folks stop deeply thinking themselves and take the easy answers instead.
