For what it's worth one can augment air conditioning with a small evaporative cooler (swamp cooler). I just dump ice into it. It uses about 75% to 85% less electricity than HVAC. Even on a hot day if I point that at me I get too cold and have to point it away and turn it down. It's not great for electronics but not as bad as all the FUD around it. Just don't point it directly at computers. I add a few drops of I/KI to keep anything from growing in it. Some people use peroxide. I like that the evaporative coolers pull even more dust out of the air than my HEPA filters.

HVAC don't require so much power, don't spread FUD.

Does this include electricity required to produce the ice?

		Does this include electricity required to produce the ice? No, I buy the ice at the grocery store. To make the ice I used required someone to spend a few cents of electricity. It is still significantly less expensive to use an evaporative cooler than HVAC even factoring in ice and the cost of delivering said ice to the grocery store. I could reduce the cost even more by getting my own ice maker, especially if I could find one of the ammonia driven devices from the early 20'th century. Society has stepped backwards in technology in this area. [1] I should add that ice is optional. It just lowers the temperature of the are a tiny bit. For many people water will be sufficient.
