...called it a thypoon.
But, there ith no thypoon!
...was not the laser considered a usless exercise in physics once? The net of today would be very different without it...
Right, there wouldn't be any Youtube videos of cats chasing the little red dot from a laser pointer!~
I'm sure they believe the Segway will replace cars as well.
It totally will. We just have to perfect that cliff-avoidance algorithm.~

...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.
