Comment on I don't have AC but my apartment lease covers unlimited water usage and the water is very cold. How can I best use this to cool my home?

- Find a pair of vehicle radiators that are as close to a box fan in size as possible.
- Zip tie them to either side of the box fan. As the fan blows: it will draw air in through the “second radiator” and blow it out through the “first radiator”.
- Hook the out of the first radiator to the in of the second using flexible hoses. Cheap garden hoses might even fit.
- Hook other hoses to the in of the first radiator and the out of the second.
- Run water on through the first radiator, out of the second. This makes the most efficient heat transfer possible.

This is exactly what I was going to suggest. Use the water to cool the radiators, and use fans to push hot air through the cool radiators, cooling the air in the process.
This is basically what AC does on a much larger scale. It uses refrigerants, a compressor, and some basic physics to cool the radiators, but it’s still the same basic concept.
