Dean drive


 

The Dean drive or Dean device was invented by Norman L. Dean, who called it a "reactionless drive" — a mechanical device that could use energy to produce linear acceleration without the use of any reaction mass. Such a device, if it existed, would revolutionize space travel, since most of a rocket's weight is devoted to carrying reaction mass. Such a device violates Newtonian physics.
