Roll your own air-conditioning. I'm a student, with limited funds and a cheap house without air conditioning. To avoid dying this summer, I've built a primitive air conditioner. It's a basic heat pump, using water as the medium. You'll probably need to fiddle a bit with the dimensions of the supplies based on your resources and preferences.
Not sure I'd do this but hey, when you're sweltering hot, anything is worth a try.
I see issues with having to refill a garbage can with ice water every couple of hours.....
But, that setup does add to the decor of the room darn it...

Yeah, I saw this on Fark, and agree with the general comments found there: this is not true AC, but merely blowing air over ice (essentially). It is also very wasteful of water.
You would generate more heat from making the ice you have to put in the thing than you could remove via this method.
However, I must admit that, had I thought of/known about this back in my dorm days (where the ice machine was in a different room and made basically unlimited ice) before I cared too much about wasting water, I would have probably done it.

Wouldn't Mister Fix-it here be better off removing his refrigerator's condenser (extending it with a little extra tubing) and motor (add longer wires) and moving them outside or into a cool basement? If the fridge is near a window (or if he doesn't mind drilling a couple of little holes in the wall behind the fridge), it wouldn't have to be much of an extension.

They used to make installed units that pumped city water like this, a friend of mine still has one in Toronto. It is pretty much not allowed anymore around here, although I don't know exactly what statute stops it (is the device banned for sale, is it against your water use agreement, whatever).
sourwookie:
Your freezer works harder if you keep loading it with warm stuff. The work it does is directly proportional to the amount of energy it has to move from inside the freezer cavity to the rest of the room. Since there is a lot more energy in a warm glass of water than the same volume of air...
If you don't keep reloading it with warm stuff having it full makes it work less. This is because when you open the door of an empty freezer a lot of warm air gets in, not so if it is full of stuff.

Your freezer does work harder. think about it this way: Imagine a row boat that has a hole in it. As long as you keep bailing, you can stay afloat. The bigger the hole, the faster you have to bail. Now, if someone comes along and dumps a bucket or two of water in there from outside, you will just have to bail faster to catch back up - right?
Well, your freezer is like a boat of cold. It must work to keep the heat out. Insulation helps slow the heat's intrusion (like the wooden planks of your boat help slow the intrusion of water) but it can't stop it (like the leak in your boat). Heat is always seeping in, and your freezer is constantly "bailing" by circulating cold freon into the coils - but the heat from that freon must go somewhere (this is slightly simplified, but basically accurate). Just touch the copper tubing on the back of your fridge and you will see where the heat goes. Unfortunately, it costs more energy to keep the heat out than the amount of heat removed from the inside of the refrigerator (see the third? law of thermodynamics). That is, the amount of temperature drop inside the freezer is not as much as the increase in temperature outside the freezer - you are creating extra waste heat.
Now, putting in warm water (directly introducing heat into the inside of the freezer box), not to mention just opening the door, is like dumping buckets of water into our previously mentioned row boat.
Does that make sense/answer your question?

The problem with growing up where it's cold during the winter(not necc. Canada) is that when it first gets hot, it feels really really hot (at least at first). On the plus side, we can wear shorts in 50 degree weather.

For what it's worth, I have a plan (in my head) for an evaporative air cooler. Basically it's a box with two compartments. The compartments are joined by a hole toward the top of the separating wall. There is a similar hole at each end of the box. These 3 holes allow air to flow from one compartment to the next and out the other side of the box.
In the first compartment, pour some water, filled to below the level of the holes in the walls (of course). Hang some strips of muslin from the lid of the box into the ice water to create a larger surface area for the water, so it evaporates quicker. In the second compartment, add a load of dessicant granules, to hopefully extract some of the moisture from the now-cooled air. Point a desk fan toward the hole at one end of the box.
Now, if my thought-experiment works, it ought to produce cool air :-)
I haven't actually built it yet, but my naive and optimistic brain is convinced it must work.
I agree with all the other posts about the wastefulness of the system in the article. Air-conditioning (or rather, air cooling in this case) is hugely inefficient, and this homebrew version seems to be even more so than a commerical unit, although the basic ideas are identical.

ajp: Evaporative air coolers are common in the form of "cooling towers", and are used frequently in large A/C installations.
The open-loop air/water system you describe (basically an a/c without the coolant) would work very well in hot dry areas (They're used extensively in the mideast iirc). Unfortunately, in hot-dry areas water is often too expensive to pump continuously through an evaporator. In hot areas where water is plentiful, the air is usually saturated with humidity already, making the evaporator, well, evaporate less.

The gravity drain is a nice feature, since it doesn't involve any moving parts or extra gear--it just works, simply. However, it also wastes water, and purchase of a small electric water pump would allow pumping water back into the reservoir rather than out the window. Thus a smaller reservoir could be used, also. Maybe like the $40 Swamp Cooler linked above, I don't know.
I was hoping when I first clicked on the link that the guy had built his own real air conditioner--those use mechanical expansion and compression of a coolant to operate, much like the can of hairspray getting cold when it's discharged, only in a continuing cycle. The linked contraption is described as a primitive Heat Pump, but as far as I know, a Heat Pump also uses a mechanical cycle with expansion/compression of a coolant.

This is the very definition of AC: Blowing air over something cold and continuously replacing the cold. His concept isn't new either it is how water cooled condensers work. The big advantages: lower head pressure (water is colder than ambient air) and you don't need an outside area to install a condensing unit (Like a ground floor coffee shop in high rise). Toronto has a big project where they extended their water intake system into deep water. They then pump this directly to cooling towers in high rises where it improves efficiency and warms the water to something that is use able by houses.
Also bring to mind 19th century ice refers though they also had an evaporative effect going for them.
Mr. Gunn writes "He should consider himself lucky. Swamp coolers don't work so well in the 90% humidity of the Southeastern States."
This isn't a swamp cooler and would have no effect on RH in the room if he covered that big vat.
Chuckles writes "They used to make installed units that pumped city water like this, a friend of mine still has one in Toronto. It is pretty much not allowed anymore around here, although I don't know exactly what statute stops it"
They probably just started to meter water. Interesting point: it is possible to effectively steal (if they pump it to generate head pressure) electricity from the water utility if you're not metered. What you do is install the head end of a turbine into your water line (preferably upstream of your pressure reducer) with the waste going to your sewer. You can get a significant amount of power 24X7 on even 40psi head pressure and a 3/4" inlet.

ajp, if you live in an environment of low humidity, then evaporative cooling is quite efficient. The unfortunate thing is it doesn't work in high humidity. Those of us who live in dry-booger states welcome the added moisture in the cool air a swamp cooler provides, and don't need a dessicant stage. Imagine the energy and heat produced to dry the dessicant when it becomes saturated.

Really effective, if you have a way to continuously pump liquid nitrogen through them. Well, then again, the back of the box fan will probably ice over, preventing air flow through the coils. So you'll have to probably have a dehumidifier inline with the boxfan some how. Good luck!

Condensation was indeed a problem, but it probably helped minutely reduce the humidity of the room.

Refrigerators are designed for a lower coil and head temperatures than A/Cs[1]. Converting one as proposed would be both horribly inefficient electricity wise (though better than this rube goldberg device) and also prone to freeze up. What you want in compression refrigeration systems is for the condensing point temperature to be at or slightly below your output design temperature. Too much variation up or down and it costs you efficiency. There are literally hundreds of different refrigerants, all with different characteristics, for different uses.
[1] For example you fridge probably never sees high side temps of much more than 150-180F with ambient around 75 and coil temps down around 32 to -10F depending on application. I've work on roof top units where the ambient air temp was 150F and high side temps were pushing 300F with coil temps around 45-55F. Sorry for all the farenhiet temps, even though Canada is metric I apprenticed under an old school guy and I think about refrigeration in F.

"It's been hovering around 30 degrees C (about 86 degrees F) in Toronto for the last week and a half. And the humidity makes it feel about 10 degrees higher. Trust me, in the summer, it's hot."
