$0 Solar Collector Heats Any Home Forever — Old Glass Bottles Do It. Big Utility Buried This

In September 1977, a retired engineer published plans for a device that heats any room for free using old glass bottles and scrap wood. The plans cost 75 cents. The device worked. Then oil prices dropped, the energy crisis ended — and the plans went back on a shelf for 48 years. This video shows you exactly how to build one this weekend for $0 to $30, depending on what you already have in your garage. No electricity. No fuel. No moving parts. One hundred and forty degrees of free heat even when it is freezing outside. And stay until the end — because there is one modification the 1977 plans did not include that increases heat output by over 15 degrees without adding a single component. 🔗 The complete Amish Home System guide — cut every household bill to zero: https://eliyodersecretsbooks.netlify.... #SolarHeater #FreHeat #DIYSolar #SolarCollector #OffGridLiving #HomesteadingTips #EnergyIndependence #DIYHomeImprovement #SolarThermal #GlassBottles #FreeEnergy #UtilityBills #SelfSufficiency #PassiveSolar #HomeHeating #DIYSolarHeater #GreenEnergy #SolarHeat #SaveMoney #EnergyBills
