Gravity Induction
From Conworld
Control of gravity is one of the key features of Progress Level 7: the Gravity Age.
The development of gravitonic science and gravitonic engineering leads to a host of miraculous devices: Levitating cars, interplanetary drives that require no reaction mass, and a wide range of military tools. Just as the application of electricity was spurred by the induction principle, the creation of devices that induce gravitational energy leads to and effective control over weight.
How it works
Gravity inductions relies on the phenomenon first set forth by Einstein in his Theory of Special Relativity: An object's mass approaches infinity as the object's velocity approaches he speed of light. By using a cyclotron to accelerate a tiny particle to near-light speed, the gravity generator creates gravitons between the particle and surrounding mass. These gravitons can be siphoned off, redirected, or stored by the use of the induction coil.
At PL 7, gravity inducers can be maintains to the size of hockey pucks for special applications. An inducer powerful enough to negate a human's gravitational attraction to the Earth is about the size of a discus, while the induction motor in a flying car requires a gravity generator about the size of a spare tire
