   That’s a neat idea to use coins as an absorber. They have a rough surface to create some turbulence and are highly conductive. However, I am confused about why the entire collector surface was not covered with coins since the foam board is not going to transfer heat nearly as well as the coins. I have tried making my own solar air heater but instead of coins for the absorber I used aluminum flashing painted black. I also created an air channel behind the absorber so less heat is lost out the glazing. You can have a look at the design here: http://practicallyoffthegrid.com/category/solar-air-heating/
