Omaha, where 540 Btu/ft^2 of sun falls on the ground and 990 falls on
a south wall on an average 24.4 F December day with a 32.9 daily max?
How about a plastic film greenhouse?
Three people can put up a $00 14'x96' greenhouse kit in a field in a day.
A 20'x24' ID greenhouse might have 7 $0 20'-diameter semi-circular bows
on 4' centers, each using 8 8' 1x3s. Screw 1x3 spacer blocks every 2' to 4,
bend them to a 10' radius, bend 4 more and screw them onto the blocks to
make a curved sandwich, add 3 24' 1x3 purlins between the bows, cover them
with a $8 24'x32' piece of 4-year UV greenhouse polyethylene film, and add
endwall framing on 4' centers with another 314 ft^2 ($6) of poly film.
Then add another greenhouse around it, 1' larger, and fill the space between
them with R36 bags of mulch, dry leaves, etc, with a few voids for windows.
If 0.9x24x(540x5.5+990x9.5) = 268K Btu of sun enters the lower third of the
south wall over 6 hours on an average December day and 6h(T-24)276ft^2/R1
leaves it during the day and 18h(65-24)276/36 leaves it at night and
24(T-24)276/36 leaves the ceiling and 24(65-24)276/36 leaves the north wall
and 24(65-24)314/36 leaves the endwalls, T = 159 F inside the south wall
and near the ceiling during the day :-) Well, maybe 130, given windows and
radiation loss from the south wall.
If C Btu/F of ceiling mass is 130 F on an average day and cools to 75 over
5 24 F cloudy days while providing 5x24(65-24)1082/36 = 148K Btu of heat,
C = 148K/(130-75) = 2689, eg 2689/62 = 43 ft^3 of water in 2 $2 20'x30"
poly film ducts laid flat 4' wide with 3" of water inside, over foil (to
avoid overheating the space below) over wire fence under the ceiling.
Solar heat, and poly film "windows," and a few PV panels and CFs...
The propane stove, and gravity fed hot water? The 130 F ceiling water might
help distill wastewater in a duct with holes near the top surrounding the
inner duct, with another duct around that to condense it and no loss of heat
to the outdoors.
And solid walls and doorlocks, vs mad dogs and a chain link/razor-wire fence.
Gee, a whole other chapter to Three Little Pigs.
Dumb, Dumber, and Total Idiot.
But then, if you want to bet on no wind storms in the winter in the
Midwest, put your money down, bub.
