Cob: second structure spacing

[Amanda Peck]

My own feeling was that you didn't want to use December 21st.  But something 
more along the lines of October 20, or whenever you want to start getting 
the sun on your floor most years, and give yourself a bunch of room towards 
the east so that morning sun hits the floor earlier (and later--late 
February?) in the year than the setting sun.  But yes, it's a triangle 
problem, with how to fish the solution out nicely stated here.  And I expect 
it works for overhangs as well.

Most likely winter's when you want the solar energy coming in.

The lowest altitute of the sun is at December 21st.   This is the degree
of one of the angles in the triangle, 90 degrees is the other.
