Hi Greg and Rodger and all
Yes, I know about hydraulic ram pumps, but the initial claim was 'This eliminates the need for an uphill pump'. A 'hydraulic ram pump' is still a pump.
Would a hydraulic ram pump get up far enough? Unlikely. 8000' of water pressure (to the top of the ranges) is about 3,600 psi. That's static: not counting friction.
