If we're talking psi energy, then the definition of TK would be a different matter. I never liked the "psionic energy" concept...seemed like an easy way for writers to explain things and create new powers on the fly.

I think Sue Richards powers are slightly different. She creates fields of force and can shape them, whereas TK is about causing or affecting motion. For example, if Jean and Sue wanted to fend off a bunch of blundering idiots, Sue would create a wall of force and slam it into them. Jean, on the other hand, would seize the attackers themselves and send them flying.
