Advantage of using the pendulum for overcoming friction versus direct pushing.

Veljko Milkovic demonstrates a scientific experiment showing the advantage of using the pendulum for overcoming friction versus direct pushing.

The goal of the experiment is to demonstrate the advantage of using the pendulum for overcoming friction force of a weight in comparison with direct pushing of it.
The arising question is does this experiment proves over unity behavior of the system or not?

Experiment Description:

Device used in experiment consists of a stand and elastic pendulum.

1. Blocked pendulum with the rest of the system can be regarded as rigid body. Using energy passed by strikes of a piston instrument, whole system can pass the path of 5mm.

2. With the same invested energy, passed by the piston instrument, the pendulum will push whole system with its kinetic energy and device will pass 15 times longer path. Further more some kinetic energy will stay unused in swinging pendulum.
