Thermodynamics, specifically refrigeration cycles.
Its probably my autism showing but the fact that we can just move funny fluid around and make heat move is absolutely fascinating. I can spend a lot of time making theoretical refrigeration cycles with different fluids, thermoelectrics, heat capacities, repurposing car junkyard AC systems, etc.
Millions of people do it for work, sure. I doubt any of them are "into it".
If you haven't before, you should play Stationeers. It sounds like you'd love it.
Oh god I already play both Space Engineers and Factorio, don't give me another 500 hour logistics game time sink...
But this one simulates the refrigeration cycle! It has proper phase changes and everything.
Empire fucking booked it to steam and has been playing it for the past 10 hours, for sure.
I bet you also enjoy Technology Connections.

Gee, what gave it away?
I popped an edible and watched his entire catalytic converter video last night. Shit's great.
The video or the edible?
Both in their respective departments :)
Ohh yeah! Though I do wonder: Why limit themselves to the guy who is evangelizing (and rightly so!) when he could also hang out with crazy swamp guy HyperspacePirate who not only thinks of the crazy cycles but actually builds some as well?
Now that's a proper special interest 🤌
What’s your favorite refrigerant
I touch r134a the most in my day to day life, cuz i fix a lot of people's car AC... But I have a soft spot for propane (R290) or propane/butane blends. Yes it's flammable to a degree but it's naturally provided, cheap as hell, zero ozone depletion and very low GWP. It has usable pressure/temperature curves that are easy for compressors to handle and can produce temperatures as low as -30C.
I've refilled old farm trucks with propane from a BBQ can and gotten good AC out of them. It's kind of cool.
I'd say it's objectively cool
You'd get along great with my dad. All he's talked about for the last year is heat pumps.
