I disagree with your conclusions about leaving and entering earths gravity well via teleportation. You're not actually moving your mass up and out of (or down and into) the well but circumventing it entirely. Love the stuff about the movement of the planet, I've actually had a short story about that in my head for years. Guy builds a teleporter and dies in deep space being the gist of it.,(reply>), That means you can generate energy out of nowhere though (which is discussed later in the video)
