a 6' high x 2' square fridge with r10 walls (2" of foam) needs about
24h(70f-40f)56ft^2/r10 = 4032 btu or 1.2 kwh/day (about 10 cents) if
the door is never opened. if a door opening requires cooling 24 ft^3
of air 30f at an energy cost of 13 btu, doubling the operating cost
requires 300 door openings a day...

sounds like it would. if you can stand less accurate temperature
control, you might try an upper and lower duct with a manual louver,
or an automatic foundation vent with louvers and an adjustable
bimetallic spring like leslie-locke's fv1-b ($12 from home depot.)

maybe you can convert that trashed lawn mower to propane, and use it
to heat the house, as well as make electricity. the heat power output
might be 10x the electrical power output.

what's the second prize? :-) you might build a wood frame, cover it with
poly film, and hang the tires over the film as siding, tied together in
some sort of giant hair net, filled with compost to make planters.
