"It was [H.G. Wells'] adolescent fiction, his imaginative stories, that live forever - and yet are not acknowledged in literature classes as being great literature. So to hell with the academics!"
- Greg Bear

Negative Gravity Field  
  Antigravity effect produced for space ship propulsion.  

For twenty or thirty miles into the back-bone of the Andean mountains massive reinforced steel tubes were driven to withstand the terrific constant strain of the tubes as they sent forth a vast field of gravitation, retarding the motion of the planet. The huge gravity screens of the tubes fed on large vats of silicon dust which broke down atomically, releasing a powerful negative field of gravity.
