Evaporative cooling kits for cars? vs aircon??
 

I know that in DRY AREAS (non humid) evaporative cooling works extremely well as long as you feed it dry air and exhaust the humid/cooled air.

ie; They DONT work like aircons where you shut the cool air in. You have to open windows etc appropriately.

So while looking at the science numbers again I had the bright idea to Google:
evap evaporative cooling kit for car
Surprisingly a LOT of hits came up. (that I have not yet looked at)

So I was wondering if anyone has experience with a car evap cooler?
Economy gains vs aircon? (You do have the added weight of having to carry water around)
Reliability of these kits?

Evaporative cooling works great till it doesn't.

It is one of freebeards often posted pictures: a VW with one hanging off the side window of an aircooled VW.

They work when the relative humidity can allow the incomming air to evaporate quickly (hence the name) and in a desert can drop the air 20 degrees. Don't work well in Chicago or many places East of the Mississippi

The only time I tried one, only the door windows rolled down, no pop-outs. I confirm that doesn't work.

Roof-mounted evaporative coolers are widely used in trucks in Brazil.
