I find it fascinating to use the natural things you have available as a motive force, and it's really cool to think all you might need is a few bits of conductor and the earth's own relatively static magnetic field to move a satellite around. I wish humans were less interested in the noisy, explosive things like engines and rockets, and more into subtlety.
