Not only did I not suggest doing this to the moon, the post you quoted me on says specifically "Mars" so I'm not sure where you're going. We were talking about getting Mars to hold on to an atmosphere. The Moon is better off without one, for my purposes. Not to mention that it's lower gravity is a positive, as well. Enough gravity to keep stuff where you put it, not enough to keep from getting to someplace else relatively easily.
Now I'm not so sure either. I must have had "Moon" on the mind. I guess that makes me a lunatic.
