New Water a superconductor?
Water is naturally a conductor, unless it is 100% pure. I don't know the chemistry or physics of this.

Superconductivity is a different beast: it involves currents that take no effort to create or maintain, hence why they are used to create (electro-) magnets.

I think.

Wade, whose knowledge of superconductivity is a bit sketchy.

New conductivity wether super or no
is the measurement of the resistance (impedence) of electricity. A superconductor has no measurable resistance. I just dont remember what the resistance of water is. If it is low we could transport through water tubes.
thanx,

New Pure water = 18.2 M-Ohm-cm.
"De-ionized" water has the highest resistivity you can get in water. When water is exposed to air it absorbs carbon dioxide and becomes acidic and its resistivity drops, so it must be continuously filtered to remain pure. It also drops due to dissolved minerals, lead, etc.

By contrast, superconductors have exactly zero resistance.

Cheers,
Scott.

Just to be fair, there's no evidence he actually knows what happened in the 1800's.
