Greetings from the Sonoran Bioregion.

I would be grateful for help regarding the relative economic 
advantage of using solar distillation versus filtration, reverse 
osmosis, ion exchange, etc.  No shortage of sun here in Arizona, so 
would a solar furnace do the trick to provide pure drinking water, with 
a charcoal finish to take out any co-distilled organics?

Any pointers to sources welcomed.

Many thanks, Dave Fuller.
