Reply to comment by lasdue in This mining tractor developed by Caterpillar is completely battery-operated by redhatGizmo
Because a pipeline isn’t cost effective to build and maintain. There’s already a road on the route. . .
The truck is fast easy cheap. A pipeline takes years and lots of money to build, install, and maintain.
A truck can carry rock. Be used anywhere anytime. A truck can move materials down several different mountains per day.

Sorry man but moving water up a hill with a vehicle sounds stupid inefficient compared to a pipeline for electricity generation purposes.
On top of the weight of the water there’s also the additional weight of the vehicles that takes extra energy to move.

The water starts at the top of the hill…. The energy is captured through regenerative braking on the trip down the hill….

There are still losses from transferring the energy from regen to the battery and then taking it out from it again. It’s inefficient and pointless.

You’re trying to pass two different things as they’d be from the same people. The truck is not tied to the whatever water thing you linked earlier.
