Anyway, I think sun synchronous orbit (basically slightly off from polar) and pointing the solar panels toward the sun and the radiator away... It's not as far fetched as people would have you believe.
But as an engineering problem it's quite another thing. For example he talks about how far you have to pump the ammonia, and then you either need a very large amount of ammonia, or you have to pump a smaller amount of ammonia very fast through kilometers of plumbing.
Of course there are highly theoretical ideas like making an atmosphere of coolant around the satellite or something but he left that stuff on the sci fi category.
The issue has always been the engineering. Programmers tend to be extremely bad at estimating he complexity of real world problems.
I think the trouble with my thinking was that I was locked into the Shuttle/STS numbers of waste heat transfer.
