Han Solo in carbonite is moved using repulsorlift technology.
Repulsorlift was a technology enabling vehicles to float or even soar above a planet's surface. This was achieved by generating thrust through opposing the gravity of the planet. Engines using repulsorlift, sometimes called "antigravs", generated negative gravity fields known as "repulsor fields", which pushed against the planet's gravitational pull.
Repulsorcrafts were vehicles that primarily used repulsorlift technology for movement, such as speeder bikes. Bakur Repulsor Corporation manufactured these engines, while Aratech Repulsor Company produced vehicles using this technology. Examples of vehicles employing repulsorlift technology include the Gian heavy patrol speeder, the Single Trooper Aerial Platform (STAP), the Flash speeder, the AAT Battle Tank, and patrol transports.
On starships, repulsorlift engines served as a secondary means of propulsion, facilitating flight within atmospheres and during docking. Many ships, like the YT-1300 light freighter, had a dedicated fusion generator to power the repulsorlifts. Smaller ships, such as the X-wing starfighter, derived energy for their repulsorlifts from their sublight engines.
Repulsorlift tech had applications in common items like chairs and speaking platforms. It could also be used as a weapon, creating shockwaves that pushed back enemies, similar to a Force push. This was seen in Mandalorian vambraces and used by Haxion Brood's bounty hunters.
