I like the ion concentration polarization concept
. If they can really build it where there is sufficent amount of water made per hour, keep it both in the size and cost range of present day RO systems these guys might get rich real quick. But the one Deep6 posted is as svHyLyte stated a Spectra Cape Horn powered by a tracking solar
panel. Unfortunatly unless I' missing something it's old school
and been done before. A simple call to Spectra would have saved them a lot of time and effort and perhaps brought them up to speed on the new stuff. Both articles state that these would be great for disater relief aid in Hati. I disagree. Smaller units like these have been sent to areas like Hati. They quickly become targets for a desperate people to steal for understandable reasons and usually have to be guarded and monitored 24/7. The amount of water these smaller units make is not worth the man power. The best method is usually very large military RO systems. Easy to drop in systems the size of tractor trailors that will produce thousands of gallons a day and warrant guards to secure them.
