500C ICs - fun
<
Bike>
the fact they try to maintain room temperature anywhere is also pretty crazy
<

I have in the kitchen a 5l container that maintains +100C delta for 4W
<
SpeedEvil>
I would be astonished if that couldn't be beaten significantly if it had proper MLI in.
<
SpeedEvil>
Of course - if you don't have a nuke - then providing even that power 24/7 is insane
<

As solar panel output is ~10-20W/m^2, tops, or perhaps 4-10W average in real life

i was going to ask if they had an RTG but i suppose that would make things even hotter
<
SpeedEvil>
Well - you don't put the RTG in the cool-box. :)
<

RTG doesn't sound like it could reject heat well
<
SpeedEvil>
That's not how it works
<
SpeedEvil>
The atmosphere is basically a liquid like water - sort-of.
<
SpeedEvil>
You have a RTG at ~300C over atmospheric, running either thermocouples - or perhaps a stirling engine - between hot and cold.
<
SpeedEvil>
you then use that power to run a chiller of some form.
<
SpeedEvil>
I don't know how much going to - say - 125C in your 'cool' box woulc help - vs 460C external.
<
SpeedEvil>
I suspect not enough over ~60C to make it worthwhile
<
whitequark>
yes, sure
<
whitequark>
I mean 1) the temperature differential is smaller 2) do we even have thermoelectric generators that function well at that temp?

Voyager RTG started out at 1200C
