Bruce, you confuse me here....

Back in the Dark Ages, I ran a company that produced various ion beam
equipment. It often required cooling. This was easy to do with a cooling
water loop in the test area, except that the ion sources were often quite
far from ground -- as much as 400kv in air. We also built higher voltage
stuff, but it was insulated with pressurized SF6.

In order that the cooling water not be a short path to ground, it had to be
non conductive, which we accomplished by deionizing it, effectively removing
all the dissolved particles. So, I know a little -- not a lot -- about
deionizing water.

Steam distilling leaves behind two kinds of things -- dissolved minerals,
such as calcium carbonate, sodium chloride, and the like, which, because
they are dissolved, are in ionic form -- and particle matter -- fine sand,
for example, that might be carried in the water.

Now, it's strictly true that if you deionize water, you remove only the
dissolved minerals, and could leave the non-ionic solids, but as a practical
matter, you're going to filter the water and remove the non-ionic solids
before you sell it. Both methods get the non H2O stuff out, although with
different methods. Both can deliver pretty good purity if you work hard
enough at it -- certainly good enough for battery water. So, I'd say they
are indeed functional equivalents.

Bzzzzt, Wrong, would you like to try for what is behind Door No. 2???

Deionized Water is not the "Functional Equivelent" of Distilled Water.
You need to go back to High School and retake Chemistry 100 my friend.
