For this reason, exposure of Nafion to tap water will “denature” the Nafion. Substitution of other cations (positively charged ions) for the hydrogen ions bound to Nafion will reduce its ability to permeate water. Depending upon the size and chemical nature of the other cations,this reduction in water permeability will be severe.

We find, however, that colloidal and molecular solutes are profoundly excluded from the vicinity of hydrophilic surfaces, to distances up to several hundred micrometers.
Desalination. Obtaining drinking water from seawater has been fraught with the problem of excessive energy requirements. This limits practicality. The separation principle outlined above is a promising alternative because it is powered by radiant energy, which is typically abundant in areas in which drinking water is most seriously needed. Hence, the idea of exploiting this principle for desalination is attractive. At present we are exploring the underlying scientific issues that could make this approach practical.
Energy from Water and Light. We found that the solute-exclusion zone is charged, while the zone beyond is oppositely charged. This separation constitutes a battery, from which current can be drawn. The battery is re-charged by incident radiant energy. Hence, the process resembles photosynthesis in that incident light yields charge-separation and useful energy. It is effectively a photoelectric effect, except that the medium is ordered water.
byLloyd » but I don't know if the images will be much appreciated by admin. They used to remove images after a while. I don't know if it's because they make it harder for low bandwidth computer users, or if it increases the chances of the forum crashing too much. So don't be surprised if they don't stick around.
byLloyd » By the way, I'm not an expert on electricity etc, but since the exclusion zone is only about half a millimeter wide next to the walls of the container,
* I talked with my brother about trying to purify water, so I hope he'll try that out soon. I suggested that he add a bunch of salt to the water and use a multimeter on it to see how strong a current the water has before and after running it through the tubes. As he pointed out, he'd have to measure the resistance in ohms, rather than the current in amps. I think the resistance should be a lot less in saltier water and higher in less salty water. Which means the current would be stronger in salty water and weak in pure water, as I think pure water is not a good conductor. So I hope to hear from him about that some day. In the mean time, anyone else is welcome to try that. I mentioned to my brother that with salt I can see a possible problem with the fact that I think the sodium and chloride separate into positive and negative ions, instead of remaining as neutral microparticles. So it's possible that this method won't desalinate saltwater. I see that the sodium is positive and the chlorine is negative. Light is supposed to separate water into negative ions along the container surfaces and positive ions in the center. It seems that the positive sodium would be attracted to the negative water and the negative chloride would move toward the positive water in the center. So we might end up with water containing sodium. But that might be better than having salt in it.
* So that's a question for anyone who's read Pollack's material. Does he explain what happens with saltwater?
