When i was explaining this in PWM terms... i was referring to the fact that while the RMS power throughput of this transmission does decrease with the speed... however while a 'jerk' is taking place, the output shaft is connected to the input shaft, in a 1:1 configuration. The only power that is lost is due to friction, since the two shafts are either directly connected, or completely disconnected. This would cause the input shaft's load to drop near zero (constant voltage) while the two shafts are not 'jerking', and when 'jerking, the motor would take the full torque of the output.
It moves like a stepper motor... just varys the number of degrees of revolution of the input shaft are connected to the output shaft... kind of like periodically engaging/disengaging a clutch VERY RAPIDLY, making little tiny high frequency steps of the output shaft. It does not change the torque, it does not generate heat (besides friction).
