…about air conditioning. And swamp coolers. And cars. And cars before air conditioning.
And I suddenly remembered 1950s air conditioning for the car on desert trips. That canvas bag hung off the front bumper; I think that was for radiator water.
But there is more. That silver jet engine looking thing feeding air into the car window; that was air conditioning in the desert.
An evaporative cooler, swamp cooler, for a car. No electrical hookup, powered by the air blown through it at speed!
