Thanks! Got it! Line 1 is the ground, Line 2 is 12v, and the other two are, umm...magic, I guess :shock:

Well, version 2.0 of my solar swamp cooler is finished. One big change I made is shitcanning the drip tube and using 1/2" pvc pipe to make a water manifold ( like Figjam ) - easier to drill uniform holes in. I'm also using plastic tube with a 1/4" I.D. and 5/16" O.D. - it goes on a better bigger fitting on my Harbor Freight solar pumps, and delivers more water ( I'm using 2 pumps now ).

The HF pumps are rated at 42 GPH, about 1/2 the one that you are using Figjam. But they were cheap and I happen to have them, so I'm using 2.

I have been watching this thread for a while and have decided to finally build one of the bucket coolers for a start. My wife will be coming with me in 2012 and she suffers from a few different medical issues. I have been looking for a way, tht doesn't involve an RV, to create a comforable environment for her at any given moment. Night time is not an issue as we can layer and get close, but the days can be hell. I really think that this is going to do the trick. I thank you for this thread and the sharing of your ideas. It makes a big difference to many people.

I am curious about minimizing the electricity usage of these. Would either of these options work for replacing the pump:
  • Gravity fed: water drips onto the pad from a reservoir above the fan at the highest rate such that no water comes off the bottom of the pad (you'd need a way to adjust the drip rate).
  • Capillary action fed: the pad is made out of a wicking material dipped into a reservoir below the fan (the amount of material could be adjusted to control the rate).
Could a solar chimney create a draft strong enough to replace the fan?

Gravity feed is going to be hard to get just right as the amount of water needed will very with the humidity.

I think that any material that can wick water fast enough won't be porse enough to allow air flow, plus dust may glog it.

YMMV

n00b 2012 here...i guess it would be safe to presume that a generator would be a critical component to this?
If so are there any affordable suggestions??

sooo....deep cycle batteries...they're sorta like car batteries, in the sense you merely connect the necessary equip (ie;swamp cooler) to it and turn them on? Is it that simple? If so, why would anyone want to buy a generator?? I know I could google 105ah deep cycle battery and research it myself, but I'm being lazy tonight... :D

A car battery is about like a 50ah battery, but their not engineered to be used this way.

Costco has a 115ah battery for $80.

Bigger camps use more power, so the hondas are very popular cause their quiet.

I designed my camp and electric trike so I would'nt need a genny. 8)

if I understand you right...if I built a swamp cooler I could simply hook it up to the 105ah terminals and it would power the cooler? how long would it hold a charge? Do you just connect it while in use and then disc when you don't need it...like at night? I presume the battery itself makes no audible sound like a generator would and suppose the cooler itself emits some low level sound - white noise...also I'm guessing its not an issue keeping the whole setup right in my tent.

You would probably need an inverter. This device has clamps that hook on the battery and then a little converter box with A/C outlets that you can plug the power cord from the pump into.

No inverter needed as everything is 12 volt.

The bucket cooler has to set outside the space being cooled, then duct the air into the space.

The intake on the box cooler is placed against any opening to draw air into the cooler.

The hot dry air is what makes an evaporative cooler work so well.

I consistently get a 30 degree reduction in tempature.

All of this is covered earlier in this thread. 8)

The bucket cooler uses 1.5 amps per hour.

My batteries are Deka 105ah AGM deep cycle.

For longest life I don't discharge below 50%.

This will let me run my cooler 5 to 6 hours a day plus some led lights for camp all week without having to recharge. 8)

Hi all,
hey i was wondering, could you use this to also(slowly) evaporate grey water?

Except that the filter, bucket, pump and pipes become contaminated with the grey-water biologicals. They may also get spread into the air.
If the grey-water is pre-treated with bleach - highly recommended for on-playa grey water anyways - perhaps the grey-water would be o.k. for this, if pre-filtered and stored separately to allow the post-treatment bleach to break-down and/or evaporate. But then what other things, like soaps, etc., may be in the water to result in smells and/or fumes being spread into your living structure.

IMHO - not worth the risk
take extra potable water for bucket cooler's use
keep it simple, reliable and isolated to ensure healthy

If you keep your grey-water processing separate, perhaps the same configuration could be useful to aid evaporation of the water within grey-water, but I'd think that the pump and a larger air-exposed filter without a fan would be more efficient. Check the grey-water processing designs.

Yesterday I did a little solar experiment. I took 4 VW battery maintenance solar panels and wired them all together in parallel. Then I hooked up a 4" computer fan to the solar panels. Much to my surprise there was enough power to start and run the fan fast enough to move air but definitely not up to design rpm's. All this in 100% cloud cover with panels horizontal. Voltage at the running fan was just under 6 volts. I'm thinking this battery less system might work for running a small swamp cooler or ventilating a tent or yurt.

I'd check it again in total sun just to make sure the fan will be effective. 8)

Idea today...

Get another 4x4 shower tent.. Add a clear plastic boot on the opening.
So I can sit in my lounge chair with a swamp cooler in the mid day.. Just watching people go by..

I brought my bucket cooler for demo's.

Sat it next to my chair blowing on my torso, so you don't need to be enclosed to be cool.

Just keep it portable so you can move it where you want it. 8)
