northwoodneil I have a friend who built about a 12x12x10 foot shed from rough cedar 10 inch thick walls filled with saw dust. It sat on an insulated concrete floor with copper lines on it. In the coldest part of the Wisconsin winter he'd start running water in the shed an inch or two at time and of course it would freeze. By the end of winter he had a block of ice the size of his shed, he'd seal it up tight and when the heat showed up he would circulate water through the copper pipe and through a radiator in his duct work. It was cold enough to condense and get the humidity out of his house. Last I knew he was working out a few kinks in the rig. I've lost touch with him but might have to look him up to see how it worked out. I've always wondered how long his ice lasted. Around here we've got snow piles that make it into May out in the sun.

oldandslow I have never lived in a home with AC and don't intend to. It makes my arthritis act up. I live in swamp cooler country which is just a name for evaporative coolers. I have a big one on top of my house. In my garage turned into a shop the garage side is uninsulated and there is a window mounted evaporated cooler to keep it nice in the summer. The other side is well insulated and that's where I do my small tinkering and reloading. It has a window mounted AC unit. No air currents around the reloading bench to bother me and since I'm not in there for long periods of time I don't get achy.

Evaporative coolers work by running water over pads usually made of shredded aspen but also some other materials and the fan sucks air thru the pads and blows it in to the house. I've never seen a home system that spray waters into the air. I put up a mister array on the patio several years ago. It will cool you off with the side effects of making you unable to see thru your glasses and becoming wet after a time. I took it down after a couple of years. I now use a portable swamp cooler and have added a mister arrangement that mists well water onto the pad which greatly increases it's efficiency but causes the water reservoir to run over after a while. It spreads out on the patio and on really hot days I kick off my shoes and put my bare feet on the cool concrete. Nice.

mauserand9mm I knew a guy years back who was going to install PVC conduits in his concrete floor slabs for a new house he was building. The house was next to a canal into the ocean and he was going to pump the cool sea water through the slab. Not sure if he ended up doing this or how well it would have worked - PVC is a poor thermal conductor and I don't think the concrete floor slabs get that hot anyway. Maybe if he pumped the sea water through a heat exchanger on a window into the house this would work. He'd have to use metal piping in the heat exchanger (for good thermal conductivity) and then have the high maintenance for clearing out any sediment or corrosion that built up over time.

Keep in mind with swamp coolers legionaries disease is a real possibility . I had it 30 years ago , got it working on a cooling tower . I hope I never get it again . Since I have had pneumonia more times than I can remember.

Hek if i can figure it out. I have the old fashioned of pay for what you use. E-12 standard. Every time I try and cut back on my usage they up the rates.
There's always some one home so no way to save (cool) only in the OFF HOURS. Sounds crazy when they want you to not cool, wash, cook during the daytime.
Here's their site.

Off topic. when I was a kid you could spot people that were on a car trip because of the canvas bag of water hanging from the front bumper.
the water wicking through the canvas evaporated which cooled the water.

Here in Phoenix Az a "Swamp Cooler" or "Evaporative Cooler" works well and extremely cheap when the Dew Point is below 50*. My electric bill is $225 using the swamp cooler. It can go over $650-700 easily with the "Air Conditioner". Swamp coolers have come a long ways. There is a two stage that dehumidifies the air slightly (stage 1) and then runs the air threw the special 8"-12" wet pad (stage 2) that helps in humid weather. The water is recirculated from the reservoir to inside the dehumidifier(over sized plastic radiator) and over the pad. I have a Master Cool one hp squirrel cage fan and a 1/40 hp pump in mine cooling 2,300 square feet. The average usage is about 4 gallons of water per hour. Wish i had the first stage. I suffer as long as i can before turning on the $air$. That means taking the wife out to eat when its to hot to cook. Like all this week.

Re: Shop cooler/grass waterer

A swamp cooler will work best in areas with low humidity. In high humidity, a swamp cooler may cause a thunderstorm inside your shop with rain running down the walls, not to mention mold.

Back in the 60s a West Texas BBQ joint had brush piled up on the roof for shade and had sprinklers spraying the brush. Real wet in the building, and musty smelling, but much cooler than the West Texas sun. ear
