Another thing that I didn't account for, as I just wanted a order of magnitude estimate, is the gravitational potential energy. As the moon is decelerated, it would drop into a lower orbit, transforming some of the potential energy into kinetic energy. The value given should therefore be interpreted as a lower bound on the amount of energy that can be extracted. | |
