Easywater.com is on TV now advertising their salt-free water

water softener. It works by inducing magic frequencies in the water
pipe which it is claimed will reduce 'static charges' in the ions in
the water. No Mg or Ca is removed since those ions are said to be good
for our health.
Since these people have figured out a way to evade the laws of
physics, their future products nay be even more remarkable.
As a humble ex-molecule mechanic, I can't figure out how this works.
Any thoughts from those of you that stayed awake in Physics 204 or
Electricity and Magnetism 102?
