| 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. |
