Agitating water molecules with heat is known to cause minerals to

Several scientific papers in the 1980s said magnetic fields could also
cause minerals suspended in hard water to precipitate. Evidently the
devices marketed in the 80s did not implement the discovery successfully.

Your right about agitating the moleucues, but that is agitating
mechanically. That's why the John gets scaled up.
However it's ******** about these devices. If the limescale
precipitated out, they would block up inside the device with scale
in no time.
The claim was that it prevented the scale from precipitating out.
Which is where the pure ******** comes in.- Hide quoted text -

Further to above I remember one of these salesmen claimed that
installing the device would somehow produce water that removed scale
already present in the system. I invited hime to explain the chemical
reaction involved. He couldn't. I made me somehow suspicious. Heh Heh.

Calcium carbonate can be calcite or one of several metastable forms:
aragonite, vaterlite, monohydrocalcite, and ikate. Bill Freije claims
to produce a harmless form of calcium carbonate with a half life of a
few days.

The precipitate that can fall to the bottom of a pan if you heat hard
water is like snow. The particles Freije talks about are too small to
drop out. They would be like the frozen mist in a cloud.

If your roof is below freezing and fog hits it, the fog will deposit
ice. If frozen mist hits your frozen roof, it will probably drift past.
That seems to be analogous to what Freije claims. If solar heat or
heat from your attic keeps the ice on your roof warmer than the dew
point of the air with the frozen mist, the ice will evaporate. That
could be analogous to the reason some customers say they became
believers when they saw lime deposits diminish.

Freije comes from an engineering family. The patent I saw suggests a
lot of research and development. After Henry Ford built his car, he
spent years on R&D before he marketed it. Many still thought it useless
and shouted, "Get a horse!"

Freije's device might not help a heating system or plumbing that wasn't
used every couple of days. It might not make it easier to shampoo.
Maybe his sales people warn such users, to avoid the problem of having
customers use the guarantee of satisfaction to back out.

Brownian effect?

That sounds similar to what the patent says. It says the particles that
can cause scaling are each surrounded by a cell of water molecules as
they float in suspension. If molecular motion busts the cells, the
particles will collide and, in the near future, not cause scaling on
their way through the plumbing.
