Ah, the computer. Understood.
How about food grade, Citation and Avatech White Mineral Oil (for example)?
...although mineral oils might actually conduct electricity. I haven't done enough research yet. In any event, I think it's quite possible to have a clear, non-conductive oil with relatively good heat transfer qualities.
There are optical fluids (oils) used in the manufacture of some high power microscopes (for example).
I snipped a portion from a site about oil cooled computers. I think it's applicable here.
"The gunk factor and the
place smelling like vegetable oil makes me think that a petrochemical or mineral oil would be the best bet.. I suppose any reasonably non-conductive fluid medium would work. Heh.. Thinned-down petroleum jelly for a porn server? I wonder how conductive gasoline is.."
I like their spunk!

i wasnt talking about your idea, i was speaking of the computer.
anyway if you were to go about it this way, you would need a "white oil"
which is totally clear, and colorless because any color or particulates
would lower the applied sunlight. this would produce more heat, yes, but the
electrical power would be reduced. from an application standpoint the
question is "is the tradeoff worth it?" it all depends on what results you
are after.

What does extreme mean?
The way I see it, there is probably less materials (no special methods for
interfacing PV panel and cooling). I visualize the PV panels in a clear, oil
tight enclosure with an inlet, outlet, a length of tubing, heat exchanger
(radiator) and circulating pump. As far as hardware is concerned, I don't
see this as a huge departure from what we've already been talking about.
Now, this thread contains lot of "it won't work" type statements which are
not supported with a hell of a lot of information. Simply put, it's a bit of
a turn-off.
So, if you have a position that questions the validity of an idea, please
back it up with something more than "that's just a touchbit extreme...".
Thank you in advance.

As we all know, there are a lot of ways to harvest waste heat but the one
that stands out in my mind is from a message posted about six months ago. I
don't know if this is a solution, but I'm definitely curious to know one way
or the other.

1) Oils are generally non-conductive so, the PV cells can be immersed in it
without shorting.
2.) Some oils can come with fairly good optical qualities - important for
passing light to PV and transforming light to electricity.
Joe: I remember reading your post about experimenting with black bodies and
it looks like you have a background that may be useful here. Maybe you can
chime in (if your reading this thread)?
