With twice the pistons, the pressure is not as great, but the volume of air
would be doubled, right?
Using logic, not physics, I think once the pressure is built up (to 13 psi) the
compressor may have to do less work to keep it there, than to maintain twice the
volume, at 6 psi.
Or, it's the same amount of work. But I doubt it will be less work on the
compressor to maintain the 6 psi with twice the pistons.

I agree with trying to use LEGO parts (as a goal), but I'm not sure about
limiting to currently available parts. I mean, do you REALLY think anyone would
try to replicate this? :)
And, if they do, the parts are available on Bricklink, right?
