Why even go that far? There is no physical reason, even for the lay-person, to require anything except Water Dust (cloud and ice shards) and electric dust (polarised electrical field as the force-screen and magnetising the debris from Crimson's attack). Yes, I agree that it's ultimately Clarke-tech, technology indistinguishable from magic. The point I'm making is that you don't have to invoke an unknown energy at all.

I should point out that I was one of the originators of the idea that there is 'Energy Dust' but, re-listening to Weiss's rant to Ruby, I'm not sure that is the case.
