...so,play gravity power as waves,in a "quantic manner"(discrete units).
It's a general principle of energy transport and transfer.
Wave is a basic shape,pattern phenomens,by which energy is transfered from one place to another,in this case from a high to a low gravitational level.
In a hydropower system,the quanta is the "head power" supply,used temporarely (pulsatory flow style).
Liquid medium moves simply the "head power",at the bottom of the dam,to a kind of water-wheel/turbine:statics becomes dynamics.
For a solid-state configuration,take a look at a hydropower system...and imagine the same working principle,with a small "self-insertion"...
