Reduce Utility Bills

This uses some electricity, but it is low cost and portable. Running a fun is much less expensive than running a cooler. This will provide relief in the summer for those with evap coolers once the monsoons hit.

I want to make one of these for my back room that has no vents. I will have a fan in the window that will pull the hot air out of the room. I was thinking about getting a used cooler like they fill with drinks, that is shape similarly. This will also allow the water to be drained out and it could be recycled by refreezing. Plus, I don’t want a Styrofoam cooler full of ice and water breaking! I would start with ice cubes to get things melting then add large pieces of ice that I can freeze in a bowl or plastic bottle with the top cut off. The larger pieces of ice will melt slower.
