the inefficiency i'm thinking of is heat transfer from that
incandescent coil to the air.  how much is lost to radiation, just
heating the heater box up?  it does have the advantage of simplicity.

one of those little ceramic cubes might not be so bad.

a heat pump would have greater complexity but it would also have the
'energy efficiency rating', eg. the multiplier of heat pumped vs.
power consumed.  and at the expense of even greater complexity it can
also dehumidify the defroster air.  [i'm trying to recall what a
5000btu room a/c draws - 120w?]
