| The new rotor will use a Kevlar-stiffened laminated transformer steel rotor and a vertical Kevlar bar with embedded permenent magnets. Kevlar is stronger and stretchier than iron or steel, so expansion joints are not needed to accomodate the stretch caused by the descent from 100 km altitude to the ground. The Kevlar backbone will provide enough stiffness to reduce "waviness", which allows for increased control circuit spacing for the ambit magnets. | || {{attachment:rotor05.png | | width=400 }} || The new rotor is composed of "block bolts", 5 millimeter square, perhaps 10 meter long blocks (or square bars) of laminated transformer steel, wrapped in thin aluminum wire hoop motor windings, and coated with amorphous diamond.
