Theoretically, with a super-large wheel design like the Hurricane, couldn't you hang the boiler under the axle?

And to the torque question, doesn't that also depend on how far out from the center the piston rods connect, too? It seems to me that, for any given piston rate, the speed would be determined by the ratio of those two radii.
