I just had to check out that video. **VERY** clever! :-)
My workshop is 10x20 with no windows and the sun heats it up in summer. I have a work bench where I was doing some polishing and detail, so I put the cooler on a stool with the tube pointed in my direction and it did a great job. Like the video said I made it in about 20 minutes.
We have A/C in the house and it normally cools off enough to sleep comfortably with the windows open at night. So, I never tried it in doors. But if it got really humid and uncomfortable I'd be quick to put the thing on a chair and point it at the bed. I might even try it with dry ice. But, freezing the plastic jugs was easy, the fridge is always working anyway.
