via

This video shows How to Make a Solar Thermal Air Heater using Corrugated Steel Panels. This design is the biggest (and likely the most powerful) solar air heater i’ve made. during the testing, the unit heated air from 50F(10C) to 145F(63C) in only 6 mins! With unit sustaining that temp – w/fan running full blast. Fan is a 92mm 12v computer case fan (solar panel powered). source/image:
