The German $59 Trick That Cools Your House From Underground

I am Otto Bergmann, a retired German master craftsman. For fifty years I have kept rooms cool in summer without leaning on a machine. In this video I show you how to cool one room for about fifty nine dollars, using nothing but the cool night air already sitting outside your window and a quiet fan to move it. No refrigerant, no permit, no monthly bill. I will also tell you honestly what this method will not do, and the plain reason no one sold it to you. Look after the small things, and the large things look after themselves. DISCLAIMER: This video is for educational and informational purposes only. All methods described are based on traditional German household practice and personal craft experience. Viewer discretion is advised. Try any new method carefully and at your own risk. #OttoBergmann #GermanMethods #OldWays #NightCooling #StayCool #NoAirConditioning #SummerTips #HomeHacks
