Cities like Phoenix or Las Vegas would simply not exist (or at best, would be 10% of their present size) without this invention.
See, I have yet to understand the mental workings of anyone who likes hot weather, or, indeed, summer. My ancestors came from England, and I am a fair-skinned female who wilts during this season. I listen to all the songs about wonderful summertime, and I think, “Yeah....oppressive, sticky, stifling heat; lack of rain; storms that take out the power; BUGS; step outside and get drenched with sweat. What’s not to like?” /s

New heard of this before. Anyone have any more information?
The Second Law of Thermodynamics says that it is easier to heat something up than it is to cool something down.
Somebody came up with a simple, do-it-yourself air conditioner, for when you have electricity, but no a/c.
You need a waterproof garbage can, a fish tank water pump, some plastic tubing and some copper tubing, small nylon or plastic tie downs, an electric fan and a lot of ice.
You fill the garbage can with water and ice, with the fish tank water pump pumping the ice water into half of the plastic tubing. In front of the fan you have tied down a spiral of copper tubing, with plastic tubes on either end.
And the other plastic tube goes back to the garbage can.
With the pump pumping and the fan on, it cools down the air a lot.
Here is a simple version:
