HI Bill,
The post office in Davis has one of those systems,  it is a variation on 
the Trombe wall. It took a fair amount of tweaking by the postmaster, 
but he got it to work very well. Today I think we would use a regular 
building frame cavity with insulated low-e glass for glazing and drywall 
painted black for the absorber, leave enough space between both for 
sufficient air movement. I would use a variable speed controller on the 
fan to keep the electric energy low and optimize the heating. I would 
also use an overhang to reduce insolation in the summer time. You can 
use the EnergyCalc spreadsheet at my website 
http://talbottsolar.com/EnergyCalc.xlt to size the south facing glass, 
we can email offline to set the overhang.
