I agree. Still think they should have stirling engine roving bots on
the moon. I'm not a rocket scientist, but seems the temperature
difference from shaded and sun side would enable them to having lots
of power.

You need to have the hot and cold at the same time with a stirling. One side
is kept hot, the other side is kept cold.

Maybe someone can explain how heat is dissipated in a
vacuum.

Radiation or conduction to something solid. No convection, and there are no
fluids to conduct to, either.
