What is a good air conditioning option for camping?
Just some thoughts I had since I’ve camped in the heat a lot. I can’t do much since I backpack ; it was only last year that I bought a cheap personal fan. If you can get one that will blow into one end of a flimsy tube (like the plastic sleeves they put newspapers into, taped end-to-end), put the fan at the top of the tent and blow the hot air outside. You could pin the exhaust end to the inside of a screen. Draw in outside air through the screen at the bottom. If you can stand the breeze, have a small fan blow directly on you. To shield your tent from the sun during the day, try one or more of those aluminized plastic emergency blankets. Swamp coolers (evaporative) only work in very dry air and need a steady supply of both power and water. It can sit outside the tent and be ducted in with the flimsy tube idea. This cools the air stream, so the cooled air must flow through the tent–it can’t be bottled up. Check the power and water consumption and make sure it’ll work in your climate...
