"...the space defense initiative drove the USSR bankrupt, and it originated at my house in Tarzana."

| Granton Motor | ||
| Spacecraft propulsion system based on gravital radiation. |
The author of this story presents another variation on the idea of a gravity-based propulsion system.
| So they built the Granton motor... It was a beautiful little thing, though, when Granton had finished; compact and efficient, and almost indestructible. The principle of it was simple: gravital radiation.
Granton had never been able to understand why gravitation had always been called a "pull"; every phenomenon known concerning the force of gravity would fit as well into the framework of a repulsive theory. He had gone on that principle: that gravity is not a pull, but a pressure pervading all space. The Granton motor was attuned to the matter-radiations of the earth, and it was insulated against the influences of the other worlds of space. It acted as a super-transformer unit, infinitely sensitive in its receiving cells to the pressure of the earth; the result was tremendous propulsive power. In operation tests it proved to be nearly ninety-nine percent efficient - as close to perfect as any manbuilt mechanism could come; harnessed to a space ship, it would be just about the ideal thing for interplanetary travel. |

You might want to compare this pseudoscience of spacecraft propulsion with some similar gravity-related systems - apergy (1880) and Cavorite (1901).
Compare to these propulsion systems: Light Pressure Propulsion (1867),
apergy (1880),
Beam-Powered Propulsion (1931),
Granton motor (1933),
Vibration-Propelled Cruiser (1928),
geodynes (1936),
ion drive (1947),
Planetary Propulsion-Blasts (1934),
stardrive (1953),
solar sail (light sail) (1962),
Lyle drive (1961),
laser cannon (1966),
Bussard ramjet (1976),
asymptotic drive (1976),
Interstellar Laser Propulsion System (1985).

'Their only check on the growth and development of Vulcan 3 lay in two clues: the amount of rock thrown up to the surface... and the amount of the raw materials and tools and parts which the computer requested.'

'Figments of his mind in one sense, of course, for he had shaped them...'
'So the parent drone carries a spotter that it launches...'

'It’s smart enough to go wrong in very complicated ways, but not smart enough to help us find out what’s wrong.'
