Repulsor projector

Repulsor projectors were repulsorlift technology used in the construction of the Galactic Empire's collector-repulsor array that required low-yield repulsorlift motors. The G-waves of hundreds of projectors were focused by a large dish, creating a field that was capable of distorting the crustal pressures of a planet. The resulting groundquakes and volcanic eruptions could devastate a civilization.
