Advancements in Vaping Technology...

But the vaccum-over-pressure system common in holding the juice in tanks is not a bad idea for making use, as it does, of the natural forces of air pressure and gravity. Those are free, and pretty dependable.

Yup, I could pretty much depend on my tanks flooding with altitude or temperature changes.

You could try to heat a plate and then spray juice on it. It becomes very hard to regulate the amount without maybe a closed loop system, for example press a button the heat starts, then the spray kicks in to regulate the temperature.
Another way to regulate a system would be vapor density in a chamber -- this would be a way to do automatic except for a switch to turn it on ("light it"). BTW the auto batteries use a microphone element and electronics.

The aluminum quick charge batteries could be useful. Even if lower capacity, with induction charging (if even that) on a base it would be easy to provide many 1 minute charge times. The supercapacitors are also cool, they might make one hit with a reasonable size. Kind of a wireless passthrough. The Mattel XV racers cars ran on them.

The main advantage of using a ceramic disk or something would be for temperature regulation, such as adding a thermostat. But it could also be good for immobilizing some kind of thin long nickel wire coils or pancakes, for temp regulation at normal or higher voltages and low power.
