Solved how to move water up a mountain without energy

[ponto]

Seems to me once the lower box drops there is nothing to bring it back up.
At some point the system would balance itself out and stop.
Anyhoo, here is a real solution using old technology, a hydraulic ram pump.
This technology has been moving water up hills since, roughly, 1797.

This example moves water through 500' of tubing and up a 100' grade.
The first 2:45 is about how he sets up his supply, the rest is the pump.

The only thing that one have to make sure is the lower box really drop, to bring it back it use different mechanism, the system that gmbajszar showing is just around 10 - 20 % of the whole system. IMO
