Do you solve your PC heating problems by typing out your long manifestos on a typewriter?i solve that by not having people in my house, or using ac

There's a host of dumb shit I should probably be doing before that.
But first, I need a one-gang two-relay wireless unit, since the swamp cooler's two (actually three, but one of 'em's a hackey time-based thing that switches the blower speed between low and high) circuits - pump and blower.

Great, I can put more money towards an adapter than I'd have in the thermostat, that "almost" works.

Don't those require a good bit of water, something else which is lacking? (I know next to nothing about them, but will Google after this post.)

There is no way that wasting water should be cheaper that electricity generation in a desert. Fucking humans...

It's an order of magnitude less water-wasting than a lawn, though.
Enthalpy of vaporization of water at 25C is around 44KJ/mol, or about 2.44MJ/L.
Average toilet flush with a modern toilet is about 6L, which is equivalent to about 14.6 MJ, or 4.06 kWh of heat removal, which is about equivalent to running a 13800 BTU air conditioner for an hour.
Assuming that air conditioner pulls about 900W when it's running based on a quick google, it's burning about 120g/hour of coal at a coil-fired power plant.
If you're running an AC unit off renewable energy, obviously it's better. But I'd pick the swamp cooler over a grid-powered AC unit from an environmental perspective.

I can see it both ways.
You're right, it's wasting water, especially if I don't run a graywater cistern for the water cycling (you can't just add, you have to cycle the water through or it'll get stanky and full of mold).
On the other hand, this isn't Arrakis, and despite the criminally insane and complicated water rights laws around here, we're not actually (according to the gov't propaganda) depleting the water table. In fact, the water utility authority just filed for a 5% rate hike on account of residents were conserving so effectively that their revenue year on year was down, and they need some more to maintain the physical plant.
