You need a heat gradient to take advantage of it. An uniformly hot place like Venus is a hard thermodynamic place. Mercury and our moon are actually interesting in that regard. I had similar fantasies as a kid, a huge pipe with a thermal fluid taking advantage of the difference in temperature between the cool and warm side of the planet/moon. But with today’s prices on solar panels, this will probably never happen.
