Modified swamp cooler. I was thinking about a modified cooler. I don't have a drawing program on my tablet so I'll just describe my idea...
Take one 15 gallon drum, lay it on its side. Best to use one that the end can be removed from. Next take some one inch aluminum tubing and snake it horizontally along the lower quarter of the drum. Air goes in from the one end and out the other.
Water goes in from a filler cap and there's an evaporation tube.
Now the physics bit... As water evaporates, it takes heat away meaning the water takes heat away from the air in the tube.
Simple, cheap and should reduce the temperature by 10 degrees.
Add a safari roof and you won't need traditional ac.
