interesting thought. shouldn't take much heating power, if air leaks
are minimal. an 8' r50 cube has 8x8x6/50 = 7.7 btu/h-f of thermal
conductance, so making it 200 f inside on a 30 f day would take about
(200-70)7.7 = 1000 btu/h or about 300 watts. one of those little 1500
watt radiant heaters with a separate thermostat might work. i wouldn't
use one with a motor, or plastic parts, since it might melt.
