Would it be possible to set up a sterling engine at the light/dark terminus on the Moon? Is there enough difference in temperature to make this feasible?

If there were a fixed terminator (light/dark border) it might be possible to consider ways to extract energy from the temperature contrast, but of course the Moon rotates.  The terminator moves around the Moon at a speed of about 16 km/hr ( 10 mph) near the equator.  there is no “dark side of the Moon”.
