No it uses magnetic attraction and repulsion to turn the rotor. The 'fuel' is magnetic flux, and the magnets will depolarize after about 30 years. I'm working on a control system, and a novel way to pull power off of these magnets as they turn.
Some of these magnetic gate projects have exploded from centrifugal forces, so there is a significant amount of power contained in this system. NASA tried to use them for satellite power, but it's hard to change magnets in orbit!
