Ionization

I don’t know for sure, but I would hazard a guess at it being down to the reactive state of the particles.
Like most atoms, if you excite them then they produce an energy source, with ions it could be possible to control their interaction, maybe exciting them on a small degree to cleanse a house (perhaps to remove any dangerous residue or chemicals left over from the fire), and too a larger degree to create enough power to acheive space flight.
I’ve also heard that ionization can remove static build up, and that term has also applied to the planets atmosphere or a planets atmosphere.
