We need here something big like this pendulum

Best idea I've heard in a while is to extract energy from the downward swing of the second stage.  Can it press down on something, do goo work, and have it cost less than the input?
IMO with some 8 y/o level engineering, just some ball bearing rolling over tracks, this could be tested.
I'm saying even that won't work, as the downward move of the 2nd stage is also there to keep the 1st stage going. Take out one ball bearing worth of anergy, and you'll need at least that to keep the thing oscillating.

If the pendulum-lever system has no load, the pendulum can oscillate and chaotic, and considerable energy is dissipated.
Certainly,  rule is valid for two-stage oscillator. The more strain output, and require lower inputs.
