Seeking highly conductive fluid

[ddwyer]

What if any (non-toxic) alternatives are there to mercury to be used as
a highly conductive fluid carrying approx 10A/cm^2 DC

An alloy made of gallium, indium and a couple other metals has been
developed that is liquid down to below 0°C.

Molten iron.

Oh, you wanted room temperature? Never mind.

Even further up the temperature spectrum, there's the material
describe in http://www-phys.llnl.gov/H_Div/GG/metalhydrofact.html
which might even exhibit superconductivity, according to some
theories. However, it seems a bit touchy to work with (3000 degrees
Kelvin, 1.4 million atmospheres of pressure).

Salt water?

Sodium dissolved in liquified (cryogenic) ammonia.

Solar photospheric plasma.

How about some UNobtanium while we're at it?

Seriously, either low melting alloys (as another
person suggested) based on indium, gallium &/or cesium

OR

Ionic conductors based on salts in aqueous solution,
you can easily get to 1 Mho/m conductivity with
salt solutions -- electrodes need be chosen with
care to avoid corrosion issues. Precious metals
if you can afford, graphite if you can't.
