My homemade air conditioner run off 12 volt battery's, which are charged by my solar panels. Viewable in my other videos. When global warming (Summer) arrives I will retire my solar furnace and use my homemade AC.
It uses eight 2 liter plastic pop bottles pre-frozen in the freezer. I plan on having a total of 24 bottles frozen so I can rotate them as needed. This unit is for the rec-room t.v. room and is limited by the length of the cord hooked to my battery's. I plan on making a AC model so I can cool the bedroom. Fan is a china built 12 watt 2 speed model maybe six inch's across. One 2 inch pvc fitting screwed into quarter inch plywood.
