Airconditioning for $30

Saw this on Fark today. Extremely crude but for those who want to try something like this you could hide it in a cabinet and could actually look and work very nice (assuming you can carry lots of ice)

That's a pretty nifty idea. A $10.00 heater core from the junk yard would make an even better heat exchanger than copper tubing. If you are removing you're rear bus heater, that would be even better as it already has a built in fan.

where to get all that ICE?

wouldn't makeing a simple swamp cooler make more since?

for those that don't know what one is, its basicly straw that has water moveing over it with a fan pulling air across it...the cool water cools the air and, in turn, the house....one for a bus could be as simple as adding a modded wet filter and water pump in front of a air intake on the roof, letting the moveing air from outside as you drive down the road act as a fan(sorta)
I can see it in my head far better than I can say it.

Yeah swamp coolers don't work in humid environments. They are great though in dry climates.

Evaporative cooling

I've been toying with an idea for an evaporative cooling system that would go under the bus. Basically, a 4" sheet-metal tube covered with that synthetic felted fibrous lawn mulch material placed inside a 6" tube, and a drip system to wet the lawn mulch. Fresh air would be drawn in through the 4" tube. Outside air would be blown between the two tubes to evaporate the water from the lawn mulch, thus cooling the walls of the 4" tube. You could fold several lengths of this back and forth under the bus, thus achieving more surface area.

I want to figure this out from a thermodynamic standpoint before putting any money into it, though, and I don't have time to fool with it right now. Or money.
