Retrograde Rotor

Early versions of the launch loop assumed that a 14 km/s, 3 kg/m rotor moved prograde relative to the launch direction. However, with transformer track windings, rather than "drag" on the rotor, the coupling can be very efficient, and can also be phased 180 degrees. This offers three advantages:

1) The per-unit-length deceleration of the rotor is smaller

2) The deflection of track and rotor can be smaller

And potentially:

3) The rotor can be slower and heavier for the same lift
