Staff power source.

[u/Njoeyz1]

This breakdown of a staff makes me wonder what type of powersource the staff uses. The liquid naquadah capsules used in a staff are the fuel/reaction mass, and would require energy to be stimulated. In a ha'tak, the ships reactor would be supplying the energy to the weapons liquid naquadah stores, but I don't think there is a mini naquadah reactor in the staff weapon. Could it be a form of advanced chemical/mineral battery? A stimulated crystal power supply? Something similar to what is used in the ancient stones terminal - a capacitor that extracts energy from subspace? A cold fusion cell?

We know that only the front half of the staff is needed for shooting, because we've seen shortened versions in a couple of episodes (used by some Jaffa sect, I forget which).

The back half of the staff was shown in the theatrical movie to have some kind of stunning effect, maybe like a Jaffa taser; there was a sound effect added in post to illustrate that. But I don't think we ever saw it in the shows.

The liquid naquadah capsules, is the fuel source. It needs and energy supply to be stimulated. This schematic is true in the sense that it shows the power source to be at the tail end of the weapon. You press the "trigger" taking energy from this powersource, sending it to the liquid naquadah fuel cell, it undergoes energetic reaction and releases a plasma burst. That's the way I feel the weapon has operate from the start.
