Solar pop can heater

 This is the heater I built before heading south.
 144 black pop cans in a box the size of a sliding glass door
 Air going in at 60 out at 127 degrees. Not bad for Nov 1 in Washington
 190 degrees in the top if the box.
Fan clicks on at 100 degrees and is powered by a small solar panel.
