I think that the Aura is just a raw biological power source.

My theory: Dust needs to have some energy added to it to activate it. It can have many ignition sources but, for personal equipment like weapons, it's the user's aura that does it.

We see Pyrrha noticably weakened from her stunt 'unlocking' Jaune's aura. I'm wondering if the characters could suffer considerable and accelerated fatigue if they have to use their equipment or auras in 'active' mode for long periods. That would make an interesting variant on the team, with one group covering for the other whilst they chug isotonic drinks or something to re-boost their personal energy levels.
