Now that's a new idea for me.  But, when I Googled it, I couldn't find
anything beyond technical language.  I need diagrams and photos to
understand things in reality.  Can your provide better links for how
absorption AC works and how feasible it would be for a residential home?

  Here are some links to start with. If you search "solar air =
you should be able to find lots more. It is not something you can buy at =

Sears, so if that is what you are looking for, this is not for you.

I checked out these links and some others.  Unfortunately, the
technology hasn't evolved to the residential market yet.  The units at
government and commercial buildings were huge, and obviously very
expensive.  I doubt that they compete with fossile fuel

  This is true, as far as I know. But spending a lot on tube collectors
but not wanting to spend much on tanks or heat exchangers, but spending
lots on awnings and letting expensive collectors go idle all summer does
not make much sense.

 This is true.  I've been studying the second tank issue.  Even a glass
lined heat exchanger tank is surprisingly costly, nearly as much as the
roof solar collector system.  As for idle collectors issue, the cost
benefit comes in winter, not summer.  I'll spend upwards of $00- per
month on natural gas during the deep of winter now, and if I install
radiant flooring to the raised foundation/hardwood floor area, the
costs could be even higher.  In summer, natural gas costs are as low as
$0- a month.  So, I'd try to use the summer heat, but to get winter
heat, having a sizeable system seems important.  The second tank, heat
exchanger system is something I'm looking into, but the prices need to
come down.  I'm not willing to take out a second mortgage to cover
these costs.
