I read somwhere the other day that water produced from condensation contains very little electrolyte. This said I wonder if you could produce a quantity of water using a pelt or chiller and then use that in your system. This is likely how they make deionized water in the first place, but would be interesting anywho. At work I often times need to measure the resistance of soil and water. It would be interesting to evaluate a variety of different compounds and see how they compare. The other day I got a drop of condensation on my 9800XT. Of course it hit right at the pci slot between the gold connectors. I just about flipped when i saw a tiny burn mark.

I only checked since my graphics were bugging out. After a quick wipe the card returned to normal.
