Super cool that the motors can be used for things other than moving the vehicle. It reminds me of how ESCs for RC vehicles us…
I always thought about this growing up. How the engine’s heat is used directly to heat the cabin and there is no heater. Also my gaming PC in the winter. It feels like free compute given I’m heating anyways.

Totally. If it's cold and you have an idle rig, you might as well use it to run a crypto miner before reaching for an actual heater.

#14The loud "pops" at superchargers and when driving after supercharging surprised me for a while. I would stop to look under the car if I had hit something. The pops while charging are sort of self-explanatory, but those while driving took me a while to associate back to the prior supercharging.
Basically, changes in temperatures are causing the pops. It's kind of weird and slightly annoying. Sometimes it happens for quite a bit after charging, particularly when driving through changing climate (i.e. climbing mountains). Having done Reno/SF round trips a good few times now, I've gotten used to it.

#15These are gonna be the new SFX in the modding community, I guarantee it.

A gasoline based ICE is so incredibly inefficient it needs to shed heat or it would melt down. It makes more heat than that it makes motive power (the thing it is designed to do...). A 50 KW engine makes 200 KW(!!) of heat (at full throttle). Most of that heat energy exits the system through the exhaust gases but there is plenty that gets stuck in the body of the engine and you need to remove it from there somehow before it causes damage. That's where your cooling system comes in, a coolant (typically: water or glycol or a mixture) passes through its own channels in the engine around the thermally loaded parts such as the cylinder and head walls to remove the heat. This coolant is pumped around in the engine using the coolant pump to a radiator, usually located at the front of the car in the airstream to help reject the heat to the environment. The interior heater of a car basically just re-routes a bit of that heat in the cooling system into the cabin through a miniature radiator with a fan connected to it that doesn't vent into the environment but into the cabin.
So there is plenty of waste heat to go around. Some diesels got so efficient though that they needed an extra in-line heater to have enough heat for the cabin in specific operating domains (low power engine, low revs).
It is effectively co-generation: you get two different kinds of energy (motive and heat) and you use them for different purposes.

What is the cause? Thermal expansion?
I have a room in my attic that can make really loud bangs on hot summer nights (enough to scare the crap out of me when I am concentrating on something and do not expect them) when it contracts again after a day in the heat. The root cause there is stick slip: the thing doesn't move for a long time due to its weight so tension builds up and then suddenly it will shift a little and the whole structure amplifies the sound from the shockwave passing through it.
Your 'pops' remind me of that (and supercharging must have some thermal effects).

Assuming you use electric resistive heat. The math changes a bit for gas or heat pumps.
Re: Normal Operating Sounds
#20Feels like a good opportunity to in addition to having the normal system diagnosis, have a process that listens to the sound the car makes and recommend bringing it into the shop if the sound sounds weird or off.
Some ACs use exactly this method. Haven't found any other household appliances that use sound for diagnostics.
