Make Your Own Air Conditioner From A Fan And 2 Ice Bottles [E0bavCOyR0x]

Save $6,000 A Year with My Complete Amish Home-Saving Method I teach:

It is the hottest week of July. The thermometer on your back porch reads ninety-eight degrees Fahrenheit at three in the afternoon. Inside your house, the kitchen has crept up to eighty-six degrees because Esther was canning peaches this morning and the wood cookstove ran from six AM to noon. The wet sheets in the windows are helping. The shade strategy is helping. But the kitchen still feels too warm to sit in, and the family is gathering for supper in twenty minutes.You walk over to the small oscillating fan in the corner. The fan that runs from the solar battery setup in the barn, twelve volts, fifty real sociedad vs real betis watts, almost free to operate. You strap two large frozen water bottles to the back of the fan with two zip ties. You turn the fan on. Within five minutes, the kitchen temperature drops from eighty-six down to seventy-five. Within ten minutes, down to sixty-eight. Cool oscillating air sweeps across the table while the family sits down to supper. The bottles last for the next six hours. The total cost of this cooling setup is zero dollars.If you watched our earlier video, Cool ANY Room by 15 for Free, you already know the passive cooling methods that handle most of summer. Wet sheets, the cellar daytime retreat, night-cool day-seal ventilation, strategic shade. Those methods get you through most weeks of summer. But there are some weeks in July and August when even the wet-sheet method needs a bit more help. For those weeks, what I show you in this video is the active cooling technique that gets you through. The 5-step build oscillating fan + two 1-liter water bottles + zip ties + 1/4 cup salt + towel underneath

The real chemistry heat transfers from warm room air into the frozen bottles as the fan blows over them, lowering airflow temperature 10-15F

The salt trick 1/4 cup table salt per 1-liter bottle lowers the freezing point of the water, so the brine stays below 32F throughout the melt cycle (the airflow stays colder for 2-3 hours longer than plain water bottles)

Real freezing point depression chemistry verified by University of Washington Chemistry Department and University of Illinois Physics Van

Verified cooling cycle 5-8 hours per pair of frozen bottles in a 12x15 foot room

Honest scope cools a single room by 10-15F, NOT whole-house cooling, NOT a window AC replacement for sustained 24-hour use

Critical safety notes BPA-free bottles only, leave headspace for water expansion, bottles must not touch fan blade, towel underneath for condensation drip

Off-grid friendly small oscillating fan draws less than 1 amp, runs from any solar battery setupThe honest math: A window AC unit costs $200-500 to purchase plus $30-50/month in electricity during peak summer = $300-500 per summer total. The fan-and-bottles setup costs under $50 one-time and almost nothing to operate. Pays for itself in the first three weeks of one summer. Continues running for free year after year.The honest positioning baked into this video. This is a supplementary technique for the hottest weeks of summer, not a replacement for the passive methods. For canning days when the kitchen needs to be sittable during peak heat. For the family room cool-down hour before bedtime. For an office, sewing room, or workshop that gets uncomfortable during peak afternoon hours. Small targeted cooling, not whole-house comfort. Used alongside the passive methods from the AC video, the seat geek combination handles even the worst heat waves without central air conditioning.There is no money in the air conditioner industry in teaching folks that a twenty-dollar fan with two frozen bottles cools a room as effectively as a two-hundred-dollar window AC for the most stressful hours of summer. There is a great deal of money in selling families window AC units, central air installations, monthly electricity bills, and annual repair contracts, every year, forever. So the simple old method sits quiet in farm kitchens and off-grid homesteads and most American families pay hundreds of dollars per summer for what twenty dollars and a quarter-cup of salt would have given them better.
