Ah, but in addition to the heat input from solar light impacting, there is 
also the heat input from radioctive decay within the earth.  As if you were
to put a soldering iron inside one of your smaller solar closets, eh?
                  
Keep up the good work, Nick.  You've already convinced me to add a solar closet
to my house... when I get a house. :-(
