How to build a Simple Homemade AC Air Cooler using an Old Juice Carton

This video shows the build of a Simple Homemade Air Cooler using a Used Tropicana half gallon Juice carton.This desktop sized unit works very well and couldn’t be simpler to makeThis is made using made a “half gallon” (specifically 59oz./1.75L) juice carton, 80mm DC fan (blue-lit), 1.5″ PVC pipe coupler and a 3/8″ square wooden dowel.It holds about 2 ice-cube trays worth of ice at a time (and it has a built-in drain! so as ice melts you can drain the ice-water into a glass for a cold drink).

Thisonly took me 10 minutes to make it. cost about $8.50.This can be run using a 12v solar panel (2.4 watt or higher), a 12v battery or wall current (just use an ac to dc transformer that puts out 12vdc).

This video shows the generation of Unlimited hot water  100% Off the Grid without electricity by converting an old propane tank to burn underwater as an immersion heater for a lot of hot water.Here,I use a homemade underwater wood stove to make a lot of hot water in a relatively short time.I also make use of the waste heat to cook breakfast.Almost 75-80 gallons of hot water in 1 hour with wood.Really a great way to heat a lot of water.

This video shows the build of a Homemade DIY Atmospheric Water Generator!.ThisUnit pulls Pure ‘distilled water’ straight out of the air. This simple design pumps near freezing water thru a long section of copper coil. Coil becomes very cold and dew (condensate) forms on the coil. The dew is then caught by a drip-pan located beneath the coil.This unit has the added benefit of dehumidifying the air.I used only aluminum and copper in this version. main thing with these is to keep the coils clean. if coils are cleaned after each use, the water generated is ‘distilled water.

This video series shows you how to make a geothermal cooling system to cool your home with the Earths natural cool temperature.10–15 feet underground, the temperature remains between 55 and 60 degrees Fahrenheit. This is true regardless of the weather above ground.The geothermal unit siphons heat from inside and vents it into the water or refrigerant in the loop. The cool temperature underground then lowers the temperature of the liquid back to 55 degrees.This cooler temperature can be used to cool your home efficiently .This build uses an old car radiator to circulate the air using a Solar Panel.
