Yeah, I know. Granted I was only 10 years old in 1993, but I still knew AOL was trouble. (FWIW, I didn't personally get online for another few years.)

The "What?" buried at the bottom of my post was an (unsuccessful) attempt to stave off the whoosh. I suppose I should use the "~" more often :-)

...The "far side" is often mistakenly called the "dark side"...

You're quite right. I was using the colloquial meanings for dark/light side. I apologize for any confusion that may have caused. The AC GP seemed to think that daylight didn't move on the moon, which is clearly false.

I agree that the heat engine idea bears further exploration. Your idea of having the piston in one place is interesting also. The ideal Carnot engine requires all the energy exchanges to be "reversible" to achieve maximum efficiency. This usually means very slow movement; much slower than we find practical in our IC and steam engines. Letting the cycle take ~28 days at a single location could get us much closer, assuming we could still harness it effectively.
