## Infinite energy?!

I am currently studying angular momentum and precession. If you suppose that you had a frictionless gyroscope with the flywheel spinning, thus precessing, could you harness the torque (converted to kinetic energy) generated about the axis of precession? since the force is generated by gravity it seems possible to me.. but then again that fails logic -____-; can someone explain to me why i am wrong?
 Recognitions: Science Advisor If gyro applies torque to generator, generator applies opposite torque on gyro. What is the direction of this torque vector? How will the gyro respond to torque in that direction? If you answer these questions correctly, it will become clear why this resource of energy is finite.

If the torque is in the opposite direction, the precession does not continue, thus it will not be able to change the direction of the angular momentum, and nutation follows. does it just fall then?
