That's funny, because the other day I had an idea for Power Armor that was powered by kinetic energy collectors.
Also, I remember how ROOTless was telling us plasma guns weren't likely to ever be created because of the size that the barrel would have to be to launch plasma at the target....
So I came up with a new idea: plasmathrower. Like a flamethrower, except it uses plasma.
Eat that, crazy physicist person!!
