Electro-Magnetic Desalination

What might be a unique concept is to use electro-magnetism.

The reason such thoughts could be considered is that the light emission wave from Na & Cl are about 400 n-m's.

And with NaCl, it may have a lowfrequency that could be repelled by a magnetic wave of opposing polarity.

This translates to about 0.4 Hz. And since light emission would be considered a positive discharge, another potential that might have opposing polarity might be able to repel sodium ions. As such, water molecules would be able to flow through such a magnetic field.

And if it matters, magnetic waves are composed of photons or light energy.
