DIY Evap. Air Cooling! How To Make “FOG” for Air Cooling! (30F drop!) – Easy DIY04:33

DIY Outdoor Evap. Air Cooling System. How to make and use “FOG” to cool down hot dry air! cooled the air from 109F to 79F during testing. only cost about $4 to make, uses No Electricity and only takes 10 minutes to make! similar to “misting style” evap air coolers but the droplets are even smaller for increased effectiveness. *the droplets evaporate almost immediately – taking the heat with them (and leaving behind a mass of cool air). works best in dry and semi-dry climates. humidity on day of testing was 8-10%. dropped temp 30F. Since the “fogger” uses only 1-2 GPH (gallons per hour) and water only costs $2.50 for 1000 gallons (or 1 penny for each 4 gallons) it’s essentially free to run! The set-up as shown can be connected to a chair, table, fence post, tree limb etc. and covers a good size area. video includes the build (near 3 min. mark) and ends with several “cool looking” shots of the sun hitting the mist. in a couple it almost looks like a ball of fire in the air. note that this could easily be converted for “off water-grid” situations. just grab a 5 gallon bucket, 12v solar panel and a 12V DC water pump. at 1-2 GPH it should run 2 to 4 hours on a fill-up.
