There's a "superbottle" in the Model 3 that's being called revolutionary in the auto industry: Tesla 'Superbottle' proves that the Model 3's disruption lies in its vertical integration What a wonderful "clean sheet" approach to needing different flow rates and even temperatures for different needs AND keeping a major component(s) in-house. I won't take any credit but who knows maybe "heat bottle" inspired smarter people to have a better idea. My "heat bottle" would add net components where this consolidates them. But with multiple flows/chambers, I've gotta wonder if it has or would be able to integrate this... IF cells refuse regen power AND heating is needed SEND max acceptable energy to heating element/chamber in Superbottle.
