Using superfluid helium as a perfusate during cooldown won't work, because
helium only becomes a superfluid (and thus frictionless) at temperatures of
less than 2K or so (I can't remember the exact temperature). While this
temperature may be raised by increasing the pressure, I don't think the
helium phase diagram will allow superfluidity at anything near 77K for any
pressure. Creative idea though! ---Mark Voelker
