[Beowulf] Server Sky - Internet and computation in orbit

I'd love computation on the moon; just as good solar collection as orbit,
but radiation shielding from craters. But what about cooling? The article
sounded a bit glib. I'm thinking, unless there's appreciable available
water, computing in space will be limited to low GHz because heat
dissipation would be limited to IR radiation? There's no coolant in space,
right? How do satellites deal with that?
