Maybe they could heat some water with it and spin some things .. or a giant thermocouple?
You'd need to keep one side of the thermocouple cold in order for it to work, and now we're back to the problem of dissipating heat...
If you boil water, now you have steam that you either need to vent overboard (limiting the lifetime of the system), or recondense, necessitating the dissipation of heat...
These are great points, I guess the could paint the backside black and make sure it never points at the sun, probably not going to cut it for 20 to 100kw per rack, maybe they could build this monstrosity on the moon and then try and use the mass as a sink. Comms over those distances doesn't really allow high capacity though.
