Looks great.  Good design.  Good to see someone doing it.  Hey, email the
local newspapers "Science and Technology" reporter and let him sit near the
vent on a cold day to learn about it.

Smart looking unit.  I like the idea.  Does it seem to heat up the
local room well?  on a sunny day, it is probably putting out total,
50,000 BTU's?

 Well based on Gary's calculator for radiation on a collector, the max
possible this time of year is  39,257 BTUs for the day, so 50,000 would be

We are still playing around with fans and getting a waiting to get a CFM
reading but haven't had a good day of sun since to test it.
More around 50-60F temp rise with 50-60CFM currently but trying to get CFMs
up closer to 80-100 with a new fan unit.
