  Oh, dang. I have the feeling this kills my hope of
immersing a coil in LN2. Anybody know what parameter of LN2
I ought to be looking up to determine if it too will drop Q?

  OTOH the relatively constant temperature of boiling LN2
will keep Q constant. But at what value?

  Oh, nice page. "Energy loss budget" is something that's
been worrying me.
