: Assuming a utilization of gravitational energy, said *hypothetical* wheel will accelerate to terminal velocity and reach equilibrium with the input energy of it's environment i.e. it won't go faster than than the energy it absorbs.
According to Einstein, the gravitational acceleration ends at lightspeed. You either reach lightspeed, or slam into somthing and stop.
The little "setup" here is for all practical purposes a gravitational bottomless pit, therefore it would terminate acceleration at lightspeed.
