So i'm posting this here because for the most part, we CFLers are a cheap DIY bunch, and so I was surfing the ol' YouTube and came across a cheap DIY AC unit. Not the design I would use for AC, but it sparked an idea... what if you replaced the frozen water bottles in this video with dry ice? I've worked with the stuff and a 5" block lasted all day without insulation sitting next to the dumpster in 70+ degree weather, so I know it'll last a little while in a cooler. It might cool your area a couple degrees, but dual purpose! That dry ice is a constant stream of CO2 as it warms up. Whatcha think?? Obviously, for any real CO2 benefits, this'll have to be tested with a PPM meter on the air, but seems like a 20 dollar setup, and where I live dry ice isn't very expensive. Not to mention dry ice would pump out WAY colder air than just frozen water in bottles. At least for a once or twice a week application, seeing as you can easily store dry ice in your freezer. This is NOT my video, and I'd like to extend my thanks to the person who originally posted it.
