Step 5: The End

Picture of The End
That was the Mini Solar A/C! Ugly but works. Add water to the cloth with a spoon until it's all soaked up, power it up with a solar panel (one or two watts), batteries, or a low voltage power source, and cool your house. Make several of these or a large scale one to lower your power bill in the summer.
Check out my other ible' for electric fire.

It's solar-powered, so is low voltage & low current - why not just put the cooler fabric on so it wicks water & set it in a pan of water & let 'r rip? I put 1 in the pickup cab for the dog, (YES, takosjza, WITH shades & sliders, windows & vents open, in the shade...), in a suitable box, running off the lighter jack. Works better than the old system of a fan and a pan of ice water - he would drink the ice water, leaving just the fan, which was ok but not as good.

does the fan blow UP or DOWN into the cloth?

down, where ever the cloth is

Wouldn't this work better if the fan pulled air through the cloth? You'd have to seal everything offso the air was being drawn through the cloth. Also if you used a highly absorbant fabric and placed the ends of it in a pan of water wouldn't it tend to keep itself wet as long as there was water for it to soak up? To those who say this type of cooler won't work in high humidity I would mention that here, in Louisiana, we have high humidity most of the time and, before the advent of the air conditioners that use freon, evaporative cooling was used extensively. In some older towns you may still see the cooling towers on top of some of the buildings. Of course it was not as efficient as the freon type but it was all that was available and it made a huge difference from the outside, un-airconditioned air.

Pushing air through works much better. Try blowing something over by exhaling, and then try to knock it over by inhaling. Which is easier?

Nice and simple, even though its more like a swamp cooler then a Air Conditioner. Seeing as I'm in the middle east at the moment and its starting to get hot I am probably going make a couple of these and see about tweaking it a bit. I'll let you know what I come up with
I made something similar using 2 thermal electric coolers hooked up to a 6 volt lantern battery instead of cloth. If you can get any of those and the heat sinks to go with them I would highly recommend it, it works pretty well to keep the heat and electricity bill down.
That sounds like it wouldn't work too well because peltier elements have a hot and a cold side. You have a fan hooked to a heatsink on the cold side and a heatsink on the hot side, the heat would radiate away from the hot side to be then absorbed by the cold side again so to make it work you would have to have the hot side outside to be able to cool.
I had it so that it was lying flat and the cold side was up, the hot side was in a project box with a fan blowing on a good sized heat sink, and a larger fan blowing on the cold side. It doesn't cool the room, it makes you feel cooler by blowing a cold wind on your face. you can also use a water cooling system for a computer

If you don't mind me asking, what brings you there? Best of luck with your tweaking...

Verry Good EXP. I like your exepiriment verry much.
does this thing work in humid areas, in mumbai we have more than 85% humidity all round the year so it's importamt to know .can anyone please inform me.
no it wont work for you... humidity must less then 50% because of evaporation try to make one like mine: http://youtu.be/jla5s_A11Pc

Ingenious. I've been looking for something like this, and you sir, are a genius. I have TONS of these fans around here.
