The usual idealized adiabatic parts are labeled "isotropic" - oh, wait, they must mean "isentropic". Duh! <BR/><BR/>(Which of course means whoever made those OH looses a lot of market cred IMO.)<BR/><BR/><I><BR/>They have a narrow window of operation, and are poorly suited to space access.

So the second claim solves a minor mystery.
