Break a chest full of steel screws near an active tokamak and have fun (don't stay in the path or get screwed)
Given that this confirms that Greg is paying attention to fluid temperatures, either we need something capable of transporting Plasmas or the Plasma Generators need to be integrated into the Reactor Casings. I know that Atomic Science does this; if Plasma from a Fusion Reactor touches anything other than Electromagnets or Electromagnet Glass (?), it annihilates it and spreads quickly to annihilate anything else nearby. (I believe it also makes the area un-enterable for a while, but that may be a bug or me misinterpreting things. Or it could be magnets.)
And the magnetism of magnetic item entities would be Fun to see. Dwarf Fortress-style 'Fun'.
