It is bogus. What it does is act as an electrical anode ending black
pipe/copper pipe electrical differences that end up as corrosion. Same
thing happens when a lot of different types of metal are connected to the
same thing. Doesn't soften the water, just disperses the charge. You can
find the same thing on gas engines in salt water for outboard boats.

There are folks that make electromagentic collars that surround the
water
intake pipe and thus make the water softer. This supposedly realigns
something in the minerals' molecular structure which then makes it
impossible for it to stick to anything. As a side benefit this process
claims that it eventually cleans out encrusted water heaters.

This has got to be totally bogus. A conventional water softener might
help.
