Winter is a strange time of year that seems to make me
hot. This is, I think, due to some warping of reality. During
the summer months, violence is threatened if 69F* or
higher is achieved. Clothing during this period is of the
short and light variety, and even then, frequent
cold drinks is advised.
During winter months, 72F, a temperature that would
cause spontaneous furniture fires in summer, becomes the
new minimum. This is combined with lots of thick woolen
garments, a much thicker duvet is brought out of storage,
supplementary heaters and flannel are spread about the
sleeping area. In these circumstances, I can't fully
understand how I'm alive.
To the solution. The typical duvet or comforter is an
insulating barrier with a pleasing heft. To improve thermal
management, I have taken inspiration from the mining
In deep mines, ventilation may be driven by heat directly.
One old trick involves having two vertical shafts connected
to distant points of the horizontal network. Lighting a fire
at the bottom of one shaft causes hot air to rise straight up
the shaft to the surface, while air is drawn down the
distant shaft, through the network to the base of the fire.
With a few crude doors, airflow can be regulated and
To achieve the same effect, I propose using structural
quilting to create a sort of conical chimney in the duvet
that sits at say, mid stomach. Excess heat will rise up the
quilted chimney to be replaced by slightly cooler air. Just
like in mines, this can be regulated by modulating the
intake valving. In this case, the foot/arm-operated gaps in
the duvet's peripheral seal. Provided the chimney doesn't
collapse under the weight of the inevitable cat, this should
lead to more comfortable snoozing.
*changing anything including the units is risky business.
**Miners are forbidden from touching the thermostat, and
are frequently warned about noxious gas emissions.
||I don't think I would want a large conical chimney because if flow reversed ,that's cold kidneys in the morning.
||I am imagining something like the walls of a termite mound. The termites alter the wall structure to regulate colony temperature. It would be some darn fine quilting though, state of the art.
||A mid-duvet chimney could be useful in venting unwanted gases too...

||A friend has told me that at least one army in the world
(though I forget which) still issues cholera belts, so just sign
up with them and get one.
||Well, there's something I didn't know. Weren't people in the
olden days foolish? Excuse me while I adjust my copper

||I was wondering whether this quilt could have tunnels through it's section and pores on either side that open and close dependent on the hump that is the sleeping person. I would be guessing that the pores would open on a concave. Internally it would open at the top of the hump and externally at the sides where the quilt levels out to the bed. The quilt would move and breathe in sync with the person.

||I asked him just now and he says no army still issues cholera
belts, though Austria did until the 1970s. He's pretty sure you
can still buy them as military surplus, though. He went online
to find out, and got distracted by a military surplus church for
