The separator is offered as a cheap means of desalinize seawater and clean water.

Remineralizing the earth at http://www.remineralize.org/ discusses restoring the soil.

Cheap diode array energy could power autonomous machines to turn compost and crush rock. Cheap electricity can move nutrient ions through soil where nitrate and phosphate ions can be brought to plants and NaCl removed. This polarity may remove water too. Referring to an old Popular Science magazune issue, liquid may be converted into a mist by being poured over the top pole of a hollow sphere that has a slit at the equator where compressed air escapes drawing away the liquid. Another Popular Science issue ('73) featured a rotary heat exchanger with great heat transfer performance.

Please imagine a wonderful and realistic future.
