Reply to comment by Weed_O_Whirler in If an object is placed at the end of of a VERY long bar that is connected to an axel, Could rotating the bar close to the axel make the object at the other move extremely fast (like light speed)? by Swade060504

Even if we assume a non flexing support rod, you'd need to apply torque to the axle to move the object. The energy required to move the object wouldn't change, so you'd be looking at infinite torque necessary to turn the axle.
