[Greenbuilding] flat plat collectors

[Joe Killian]

  Clarke,
    Do a search on Trickledown solar, or Modified Trickledown.
    Very cost effective.  I'm planning on doing one, after some other 
must-do items get handled first.   There are a number of examples out 
there, starting with Thomason's design in the 60's, I believe still 
providing heat for a Vermont building.

A few links:
