or better yet...an automated motion detector misting system ... :) i had a dream of a simple bucket a/c system....oh...it was icy cold, and the more i think about it ...i doubt it would work in playareality.

There is a balance between really good ventilation and directed airflow... the opening of a window creates directed airflow through the room or house you are looking to cool. The rate of motion through the tent from door then through say roof vent is going to be quite rapid and the cooling effect will dissipate before it can be effective or show a temp drop. A house or a warehouse has an internal size large enough to allow the saturation point of the air to be attained before it moves from the space. A tent by it's nature is not going to really lend itself to that scenario especially with a unit as small as a 5 gallon bucket and maybe 40 cfm of airflow from a computer fan. I think the far more effective way to use water to cool is to saturate say a shirt and put it on the body. Not solar mess, no wires no bucket no ice... real simple... or a more complicated method... a spray bottle and water... Spray on skin and repeat. JSin

you need air flow for a SC to work. as the humid air warms up, ( which happens pretty quickly) it has to exit, and you replace it with new cool humid air. That's why a SC uses so much water. In a house you have to have a window open while you run the SC. It's not like an air conditioner, that only works in an enclosed, recirculating mode

The other problem is if your tent has good ventilation to get even a relatively discernible drop in temp you need a LOT of airflow... I mean serious airflow cause you would need to increase the humidity for just about the whole playa. Really dry air wants to take on water. Good ventilation brings in even more dry air that the water can dissipate into.. Frankly I don't see it happening. If you get any cooling effect at all it will be from the reduced temp of the ice... Not the same thing as a swamp cooler JSin

The ultra low humidity will use a LOT of water, as much as 5 gal an hour. you don't need the ice to make a S.C work well. You have to pull the dry air THROUGH the filter material, and the material has to be fairly open to allow unrestricted air flow.

ok, so..i'm thinking of building a small simple swamp cooler out of a 10gal bucket. to cool off my tent a bit for BM. I'm thinking: a 10 gal bucket a solar fan system...one small computer type fan pulling hot air from my tent into the bucket from the side, and another fan on top, blowing the cooler air out. for the solar....using 1-2 of those solar garden light solar pannels......(idono) a block of ice in the bucket, surrounded by.....humidity filters...like the ones the humidifier takes?? plus a UV led light to control bacteria growth. (also connected to the solar panel). micro filters...(er...air filters made for heating ducts etc...retro fitted of course...) on the intake fan to prevent playa dust from clogging it up tooo bad. would this work? i'm currently doing home tests....please let me know your input. or if you've tried this....thanks! :) the block of ice would have to be replaced as needed.... idunno...it sounds like it would work to me.....but any advice would be appreciated! Thanks! Penguin a small inexpensive solar bucket swamp cooler ideer....

Here is a photo of the one I made. This is my second try, I made my first one for the playa last year (previous posts in this thread) it worked but the fan was too small and it burned up after a short time. I found a larger fan that plugs into a cigarette lighter and a bilge pump at the boat shop. I'm going to try it again. I'll let you know how my second attempt went. http://people.tribe.net/edward/photos/5d56149b-e37a-4c14-89e6-c9aeb18699b1

Swamp coolers are great for the playa as it is on the order of 5% humidity there. I have a different unit this year. I managed to pick up an older "portable" industrial cooler that is well made of steel and has a single motor that powers the blower and the pump. It is AC 120volt though. I tried it out with my deep cycle and a 300 watt inverter and it ran for 7 hours before the battery dropped below 80% charge. It blows nice cool air on a hot day. I think it will cool a 10X 12 tent well. I also have a shade cover to go over the tent and that will also help. I think I am set. Best of all, our camp is sporting a grid this year so the battery will only be a "Backup" power source. If you read my original post, The old swamp cooler was smaller, didn't cool too well and used more electricity. I guess it was just a POS as the free one works better and will run from my small inverter. I still want a 12 volt one though...

Greg, So how much of our precious water supply did you use to cool your garage ? In many aerias ( south west ) you wouldn't be allowed to do that, water conservation is a maj. issue. Here in GA. right now ( drought) it would get you a ticket from the water cops. The effectivness of a swamp cooler is controled by the relitive humidity, above about 30% it isn't worth the expence of running it. much above that, it woun't work at all. And a mist sprayer with a fan is NOT a swamp cooler. An S.C. has a evaporating pad that cools the dryer air as it passes through it. mist sprayer puts water on you or whatever, and the moving air evaporates it off of your body. that would work as a personal cooling device on tha plya, but you couldn't cool a camper or tent with it. I lived in the high desert of s.w. NM. so I'm very familure with all of this on a practile levil. A second roof, made in a tent fashion from a silver propaline tarp, severail inches above the garage roof, blocking the sun, but alowing air movment between the two works very well. And you won't have ceder chips all over everything but your roof after the next big wind.

OK people you've been misled. By me, the washer pump is the absolutely perfectly suited pump for this, if your willing to replace it after 10 min of continuous use. I'm very near St. Louis, look at the weather map and you can see why this kinda thing is on my agenda. today, in my garage (28'X36') it reached 132 degrees at 7' elevation. A 30 gallon propane tank filled to 120psi and regulated to 25psi connected to a 5 gallon plastic gas can full of water, pushing the water through two 1/4" fish tank hoses(reverse bong) with "Dripmaster Adjustable flow Mist sprayers" model# 61032d will emit two gallons per hour continuous. I let this run until the water ran out and there was alot of air left. Two gallons per hour was the best adjustment for the finest mist and could really put out way too much water if adjusted up. I bought the sprayers awhile back for 55 cents on clearance, I also got a 750GPH bilge pump for my old boat in the same sale ($3.50) NO WAY won't even produce mist?? The washer pump would have worked the best if it would hold up. I'm keeping it mounted in the juice container for watering "plants". Although, I did have it connected to a DC power supply at 20v for the best mist, but at 12v it still smoked after awhile. This is leading somwhere, I promise. While searching for information I ran across matierials regarding roof cooling. This is the source of the heat. After checking into it I was ready to try it. In order to try and get it close on the first attempt I broke out the math. One gallon of water at 100 degrees will dissapate 8500 BTUs. Since my Uncle is a master plumber with a formal education in Hydrodynamics and City Engineering, I opted to call him about the flow rate of my water supply. He began by going ito the specific history and theory of dissapation and the pre-freon cooling of building and the relatio...... and We ended up discussing Cheney and his shooting people in the face fetish. Because roof cooling is far and away more effective than interal dissapation there's not really a need to be that specific. He did say that cedar chips about 3/4" in size were the best medium for the coolng pad thing. Enter Ritchie, "Man it's so f*(&^)#ng hot i've already died. And i gotta go home to my trailer where the power has been off since yesterday and wont come on 'til the landlord fixes a bunch of crap..... what is that thing?" I told him it's a Swamp cooler. He immediately said " no it's not, when we lived in Denver We had one and they don't do that much to cool the house anyway. We had to run the A/C then run that, A/C then that it was like they were battling it out". I was done with the cooler idea anyway, and was ready to put two $5.00 sprinklers Y-d off of my garden hose on the roof. He split, I turned on the water and BAM!! 15 degee drop in 10 minutes. It didn't stop there, overall by the time the sun just started to leave the roof it fell 37 degrees in about an hour and 15 minutes. I'm thinking if you started misting the roof before it got to hot you could maintain the temp as if in total shde just by keeping it damp. If the contents and structure never got saturated with heat it would be very effective. Ritchie came back around 10pm and admitted that he stole my idea and sprayed his 14X70's roof and sides with the most exposure. He said it worked so good he was shocked. By the time the electric came on the A/C wasn't even working hard to cool it off. Then took another hose and sprinkler, and in clasic Ritchie fashion, split. I know this is a hell of a long post, but i won't die trying to pay my bills now, so I'm pleased.

You WANT humidity with S. coolers, that's how they work. And they only work in dry conditions ( low humidity) I'd try this gizmo out pre-plya, I'm thinking in those conditions, maybe 4-6 hours. It's realy hot out there !

I'll let you know how long the ice will last in the cooler. Actually I am freezing 15 water bottles to fill the cooler. It will help to eliminate a lot of the humidity that is caused by most swamp coolers. I'm not sure how long I need to run the fan to be comfortable or how long it will take to cool my space. In any event, I will post my review of the product. Regards

That kooleraire thing is only usefull for a short time. How fast do you think the ice is going to melt, with warm / hot air blowing across it ? You'd have to have acess to a lot of ice out on the plya. And you dont need a pump if you go gravity fed, and regulate the water flow ( which you should do anyway to conservr your water) there are a lot of clip on 12v fans out there, check truck stops. if you mount the fan so that the center if the blades is just inside of the box, it will draw air through the cooling pads very well. Rember you HAVE to let as much air out of the cooled space as you draw in through the swamp cooler for it to work. other wise it only makes the air more humid, not cooler. and the air going into the s.cooler has to be dry, you cannot re-circulate the air inside of the cooled space.

It took me 10min to get here and i joined just to reply to this posting, so please don't say that youv'e finished this deal. Get the blower motor, windshield washer pump, blower switch and headlight switch from a GM product from 1990-1998, prefferably a mid-size. Lumina ect. The headlight switch can regulate voltage for pump speed and the blower for the (duh) blower speed. In St. Louis, there is a "Pick-a-Part" at which these parts would be around $20 and very easy to pull. Since it's part of a conglomerate based in CA , I'd assume it's the same there. If you were to find a Silhouette or Lumina APV (minivan-very ugly) that has a rear A/C unit, you could convert it easily and the entire package would be built in one unit for you I'm not an expert on this but i do know that if you have an A/C unit to run for a few minutes before and intermittently (but not simultaneously) it really cuts down the humidity and energy consumption, plus no mold will grow in the RV.. Now you can use the money saved and get one of these, it does cost $199.00, but is very useful. http://www.harborfreightusa.com/usa/itemdisplay/displayItem.do?itemid=90599 from here http://www.harborfreightusa.com/usa/storelocator/locationsByState.do?state=CA or here http://search.harborfreight.com/cpisearch/web/search.do?keyword=solar+panel&Submit=Go I hope this helps, wheeliedart

I found the squirrel cage fan on ebay. It may be too late for buying something from ebay to use for burningman unless you get it shipped overnight. I also saw a 12v fan at radio shack that is normally used for car audio equipment. It was around $10. I don't know how much air it moved but it might be worth looking into.

I got mine together and it just does not move enough air with the fans I have. Unless I can find a squirrel cage from a car in the next few days i am shelving it for the year. Btw, I bought the real evap pad, 24 X 36 at True value for 3.99. That's pretty cheap.

Not really a new idea... http://www.realgoods.com/renew/shop/product.cfm/dp/2500/sd/2505/ts/3181949 you could use their basic design as a model to build your own. But it isn't going to cool you off at night when its still hot outside, however at least there would be *some* relief from the daytime heat if you aren't accustomed to desert life. Its really just a matter of buying a regular evaporative cooler and replacing the motors with DC motors compatible with your solar source (cooler sized according to solar panel).

After reading this post I decided to try to build a 12 volt swamp cooler too. Smaller seemed to be a good idea for me. I have a small travel trailer and only one 15 watt solar panel with a single battery. So my running time would be limited. I was thinking I could make it small enough to set on the cabinet next to my bed. I used a small rubbermaid tub. I cut holes in the side with a dremmel for my homemade cooler pads and the squirrel cage fan. For the cooler pads I took pieces of stucco lathe, wrapped them in cheese cloth and attatched it with zip ties to the side. I drilled holes in 5/8 tubing and ran it over the pads. I found a bilge pump at the marine store, a rule 360 GPH for $17. That was way too much water for the size of my pads, so I diverted most of the water back into the bottom of the tub. It seems to work well. The bilge pump really is a good idea. I tried different 12 volt a/c fountain pumps but I would have had to use a transformer and an inverter. I also tried a windshield wiper pump from the pick and pull junkyard. The windshield wiper pump has to work too hard for it to last a week in the desert. The only problem with using a rubbermaid tub for the body is that it leaks air around the lid so I have to put duct tape aound it to seal the top, Other than that it works well and blows a fair amout of air. Bad-Dawg, thanks for the idea. I'm going to be nice and cool on the playa.

I saw something similar at CalEarth in San Bernardino County. it was real cool but the chimney tower was quite tall. I have actually been toying with the idea at my home.

In Tucson at the Environmental Research laboratory there was an experiment done with semi passive evaps. A chimney was built on the east side of the house with vents built into the west side top of the wall. a small pump kept the pads of the evap cooler mounted atop the chimney wet and the cool air drops, which it wants to do. . .thus displacing the warm air in the house, which rose out the vents on the west side. 110 degrees outside. . .74 degrees inside. you could adapt this to your rv by just having a small pump and no fan. . .cooler at one end and window cracked at the other. test it out before you hit the road. if that doesn't move enough air a small fan might be enough.

I was thinking of doing just about the same thing in my bus this year. I don't have any experience with swamp coolers, but looking around I saw one of those $300 coolers that uses 1 gallon/hour and claims to cool 400 sq ft One thing I was going to try was just a drip feed instead of a pump. I think with just a resevoir jug, a little tubing and a cheapo valve you could get a trickle going that would keep the pads wet. I'd probably have a reclaimation pan under everything to catch any overflow. If you really want a pump, try looking into aquarium or hydroponic hardware - they should pump at a more reasonable rate. I'll try to take some pictures once I get going on my homemade version.

So, thinking of burning man in my motorhome this year, I don't want to run the AC as I would have to run the genny, I do have a portable 120VAC swamp cooler but it uses a lot of juice for the inverter to run it and My 300 watt inverter won't do it. I have an 800Watt one that will but again, it uses a lot of juice and runs down tha batteries quickly. So I priced 12 volt portable swamp coolers and they are in the $300.00 range... for a fan and a pump in a pretty box... Go figure. Plan B: So I got to thinking I can build one. I picked up 2 big ass Pabst 12vdc muffin fans in a cool fiberglass hood that I scrapped out of an old pictureTel video conference system. I looked them up and they move 240CFM each so I think they will pull enough air. Now, on to the pump. I have a rule 1000 bilge pump (1000gallons per hour at 0ft head). I will try it out but I am wondering... Is that too much water to the evap. pads? Would I be better off with some other pump? What pump? Anybody have a line on cheap long duty 12vdc pumps? B-D
