I wonder if anyone has looked into using a liquid coolant

Hummm, not exactly what I was referring to. That sort
of system has been around for years. I'm thinking of
a combination system on a small scale for a home. A
solar cell system combined with a liquid heat collector.
It shouldn't be too hard to develop.
