As I understand it, that's because the field is spherical. If you place a sphere in a river it can only go straight downstream. However if you combine two or more spheres in a line and angle that line with respect to the flow, it's possible to move diagonally downstream to reach either shore.
- ethbro 9y agoTrue, but the magnitude of any locally-tangential component to a spacecraft would be relative to the angular difference in the spheres' locations, relative to the nearest star. No? Which is to say, impractical for any substantial radius from the solar system's center.
- mLuby 9y agoRight, it wouldn't exactly turn on a dime. :D Still, being able to turn at all dramatically increases the usefulness of the drive.
