Millis space drivesSeven types of hypothetical space drives suggested by Marc Millis of the Breakthrough Propulsion Physics Program at NASA's Glenn Research Center (see Millis drives). Three are speculative and closely-related varieties of space sail: the differential sail, the diode sail, and the induction sail. The four others are the bias drive, the diametric drive, the disjunction drive, and the induction ring.
