Some iconoclastic futurist (Esfandiary?) suggested that it is silly to
heat the air and other objects in our houses, when what we want to heat
is the people. He suggested turning the house into a giant, low-power
microwave oven. This will heat up the people inside without doing much
heating to other objects, saving energy.

Maybe your tent could use a similar idea, positioning a few microwave
radiators around the interior, aimed at your body, to keep you warm without
trying to heat air and keep a thermal gradient at the thing tent boundary.
