Since the day last week when I had air conditioner repair in NYC, I’ve been a bit more careful about how much I use the air conditioner. I used to use it all the time, but that overuse is what caused it to break in the first place. I would even leave it on while I wasn’t at home. Now I only leave it on as long as necessary and use other methods of keeping cool. In addition to extending the life of the air conditioner, I’m saving money o my energy bill and helping out the environment.

I came up with an idea to cool myself without using the air conditioner. It involves a regular fan hooked up to a solar power source. The power source uses solar cells to spin the fan blade so it can blow air. Of course, if the air is hot, only the same hot air will be blown around the room, so something is needed to cool the air. For this, I have a chest full of ice cubes and water, some copper tubing, a water pump, and a few zip ties.

The cool ice water is pumped up through the copper tubing by the water pump. The copper tubing is attached to the front of the fan. When the hot air blows past the copper tubing, it becomes cold air and the water heats up a little. The water flows back into the chest and the cycle repeats, producing a steady flow of cool air until the ice completely melts and the water reaches room temperature. This contraption is essentially a personal air cooler, but it uses less energy than a standard air conditioner. It’s not meant to replace my air conditioner, only to be used with it when the situation calls for it.
