that much i get, it does seem pretty low on torque but as one user said scale it up it will have more mass=more momentum=more torque
also keep in mind rather than attaching a generator physically to the device, you could instead have the arm of the generator moved also by magnetism, so it would not inhibit the device's movement as much, this idea is already in use in many wind generators, they replace the inner mechanics of them with magnetic ones that don’t actually touch so that the parts never wear down
