Gravity does not go away on the space
station. It has its own and is orbiting
in the Earth's field.
There is no zero gravity technology. Weight is weight...
It cannot go away that way.
NASA would disagree with you. Google search, "zero gravity technology".

Take a virtual tour of our Zero Gravity Research Facility.
The Zero Gravity Research Facility provides a near weightless or microgravity environment for a duration of 5.18 seconds. This is accomplished by allowing the experiment vehicle to free fall, in a vacuum, a distance of 432 feet (132 m). The facility can
provide a microgravity test environment for a fraction of the cost conducting an experiment in space and provides the best gravity levels of any of NASA’s ground based low gravity facilities.
Experimental Drop Vehicles used in the Zero-G Facility can accomodate payloads up to 1000 lbs (455 kg).
The free fall is conducted inside of a 467 foot (142 m) long steel vacuum chamber. Chamber pressure is reduced to 0.05 torr (760 torr = standard atmospheric pressure).
The Zero-G facility was originally designed and built during the space race era of the 1960s to support research and development of space flight components and fluid systems, in a weightless environment.
Microgravity, which is the condition of relative near weightlessness, can only be achieved on Earth by putting an object in a state of free fall. NASA conducts microgravity experiments on earth using drops towers and aircraft flying parabolic
trajectories.
