Got the idea from a friend. So i started making up my own. Take a box(whatever), put a fan at one end, some ice (what have you) and blow air across it.

Here's my rendition.

Before the Civil War there was a big business cutting ice in the northern states and bringing it to the southern states for cooling rooms. They used saw dust to insulate the ice.

I remember my grandfather had one of those evaporative coolers that mounted on the car window. Supposedly the air going by evaporated water in the gadget and then cooled air was blown into the car. Didn't seem to do much good but, I was only ten then. Good Luck, Rick

I failed to get that pic so far but, will try again later.

I'll be loading this with 3 2.5 liter frozen jugs and a couple half gallon milk jugs! Should cool me down some!

I knew a local guy that had one of those evaporative window coolers he displayed with his car. claimed he bought it California when he lived there and they used to load it with dry ice. Said it worked fairly well when you were moving and not at all sitting still.

I agree with the frozen jugs.  I first thought that just ice in a humid area like mine would just make my shop more humid.  Great idea.

Evaporative coolers work very well when dew points are low, in high humidity they are basically just a fan.

When I was in boot camp I made friends with the supply sargeant(Yancy). I got put on water detail with him the first week. I did what he said and got everything squared away quickly. He liked that I didn't require supervision so from then on I was detailed to him when ever we went to the field. Because we used to take a duece and a half out to the training sites, way ahead of the company, we had lots of time to kill. As soon as we got out there, I would set up the lister bags in a shady area and fill them. we then wet down the outside of them so that evaporation would cool then. He also showed me to wet my canteen cover so that it would cool my canteen. It works. No one else told me about that. I passed it on to the others in my platoon. There are alot of simple but effective techniques out there. Good Luck, Rick

I ain't worried about humidity as we already have that. If it blows cooler air, then I'm happy!

I've seen these made out of 5 gallon buckets using dry ice & also coolers with hair dryers rigged for the fans.

I have an idea I'm going to try out, I would like to solar power a shallow water pump. Well water in my area is around 50 degrees I want to set up a recirculating system using well water thru a coil enclosed in a insulated sheet metal duct with a solar powered fan inside. The spent water will be sent back to the ground via a vertical French drain next to the well point pipe and cool my insulated garage the plans are in the works.

Another idea, where a solar powered recirculating pump can be incorporated in the system, cool well water, a automotive, truck, whatever, radiator in the system and solar powered fan blowing air through it.

A 5000 btu window unit is less than $ 85 and dehumidifies the air at the same time. I picked one up in a Boy Scout yard sale for $ 20.

I believe they were called swamp coolers, I have one for my 72 VW bus that I brought back with me from Hawaii when I retired from the Navy.
