I think that you must have meant increase efficiency. If so the following
material list should test out the theory.

Phase 1 Material list:
Radio Shack laser pointer
copper tube to wrap around the relevant part
homemade expansion chamber
a bottle of nitrogen
suitable eye protection

And you're ready to cut tin foil? I don't see a lot of cost in this
experiment!

If phase 1 works you could build a mini hexapod for a few hundred and run
it with emc and make a project that would interest a lot of folk.
