“A future outdoor hot tub would have some major design changes. It would be much, much smaller, giving us less water to heat. It would have a thorough insulation layer on top. (A thick layer of ping-pong balls would be especially fun, as you could get into the tub, displacing the balls, and keep it insulated even as you soaked in it.) It would have a radically redesigned stove, likely an ash can with two chimneys, one for air intake, another for smoke output.
And it would probably be built some warm summer evening, not during a freaking snow storm. As should be clear from this post, we’re idiots.”
