Of course, cooling the wire requires energy, which is counter productive. Or you could let the water heat up and pump it elsewhere to cool off naturally. But then you would only have room temperature water, which would not effect the resistance of the wire.

cooling is only feasible for super conducting.

Sirus, can't you only do the texture for the base gray scale item and let greg's color modulation do the rest?

Even then, not for power supply. Super conducting is useful only in circumstances where you give 0 shits about energy efficiency.

There aren't many circumstances like that.
