Don't Buy an AC! Build This $15 Copper Cooler Instead

This isn't just a fan hack. It's a 2,500-year-old engineering principle that quietly disappeared from the modern home, not because it stopped working, but because it never fit the business model of an entire industry. If you've ever wondered why your power bill spikes every summer, this breaks down exactly where that money is going and what a fifteen dollar alternative looks like when the physics actually checks out. Every number in this video is pulled from real HVAC industry data and historical sources, not guesswork. Sources referenced: U.S. Department of Energy and EIA data on residential air conditioning electricity consumption, HVAC industry comparisons on evaporative cooling efficiency (Fixr, Gorman's, Aspen Creek HVAC), and historical research on Persian badgir windcatchers and qanat systems (ArchDaily, Taste Iran, Wikipedia, France 24).
