	<htmltext>This process depends on evaporation to concentrate the brine. Can someone more familiar with the process costs explain why it's cheaper to use ion exchange rather than distilling the water that was evaporated?<p>
The source of the energy to evaporate the water is irrelevant, solar works just as well for either process.  Assuming an essentially unlimited supply of seawater for cooling to the distillation step, I don't see how they can make enough concentrated brine to filter the seawater more cheaply.</p></htmltext>

	<htmltext>This idea of ion bridges has been around a long time.  The application here is basically misrepresented.  All it is doing is replacing a small amount of commercial electric power with solar-generated potentials.  But the process isn't feasible when run on commercial power, even if the power is free, so replacing the commercial power with solar (the germ of the "idea" here) is just disguising the dead horse.

Reminds me of the algae gambit: the solar constant crossed by photosynthesis is dismal, so no biofuel (corn ethanol, biodiesel, etc) can possibly be effective, but if you photosynthesize with algae, the very irony of pond scum making something useful is enough to make you (briefly) forget physical limits.  Notional fantasies vs genuine engineering.</htmltext>

	<htmltext><i>The key piece of the work is an ion bridge.</i> <br> <br>

No, the key piece of work is the idea. Ion bridges have been around forever.<br> <br>

<i>This has to permit the travel of one kind of ion but not the other, i.e. Na+ or Cl-. Looks like this material could be expensive.</i> <br> <br>

So you use, for instance, a polymer electrolyte (ionomer) with negatively charged side-chains for one bridge and a polymer with positively charged side-chains on the other. Only the counterions are mobile. The article says they're using modified polystyrene. This is not new, or terribly expensive. Similar things are already being used in industrial desalination technology for ion exchange columns.<br> <br>

<i>It might plug up need to be periodically replaced. </i> <br> <br>

Plug up with what? You naturally would have a mechanical filter to keep the crap out. It's not a major problem.<br> <br>

<i>How expensive these are? How non toxic these are? What is needed to manufacture them? These are the questions we need to ask.</i> <br> <br>

No, they're the questions asked by someone who doesn't know s--t about chemistry/chemical engineering. I happen to have a degree in the subject, but damnit, I learned about (used, even) polymer ion exchange columns in high school. If you want answers to your questions, go get Coulson &amp; Richardson or some other chemical engineering textbook, and find the relevant section.<br>

This technology is certainly very clever, but it does not make use of any new technology. The only question I think is worth asking here is whether or not it turns out to be more efficient or not.</htmltext>
