Same input-greater output...

[Alexioco]

....it's a simple logic :

     -an off-balance lever (equal masses,unequal arms/"h" is their difference ).

      -starting unbalance: long arm on top position.

      -due to unbalance state and gravity "pressure",the mass on long arm plays positive work(torque),the mass on short arm plays negative work (torque).

      -the motion of the lever (fall) is determined by their torque difference.

       -if we are interested (really...!),to collect more power,we need more space (height "H")...or time (v=g*t).

       -if we have more stored power,we can easy to remake the starting unbalance ( mgh),to "pay" friction and to take out some power supply...

Yes the greater the fall, the greater the energy, but how do you get it make it back to its starting position in order to repeat?

.... is the first sequence:gravity fall working as an unbalance amplifier.
 
      The second sequence is an UNBALANCE JUMP...

      The classical and old (15-th century...) simple hinged arm,as a natural suggestion (leg,arm) is the best expression,for the "self"- switch of unbalance from bottom to top position.

      To get a continuous process ,we need to use a part of the  stored power for a second unbalance jump(small input...)...in some manner.

      All together,we must play a mechanical unbalance amplifier(due to gravity),then a mechanical oscillator (due to rotational inertia)...
