Isn’t the problem ultimately that water is heavy and it takes a lot of power to pump it and that’s expensive?

You can pump water faster through a big tube but then you need big pumps and tons of electricity. If it’s going uphill that’s going to be serious power.

1 ton of water is only 240 gallons. So if we're talking a tube that is 4 feet in diameter and 10 miles long, that's 12.5 million gallons, or 52100 tons (or 104,000,000 pounds). While it wouldn't take that much to move that if your pushing downhill, I have to imagine the energy cost would be AMAZING moving it uphill at all.

But also fluid dynamics is the only college course I dropped because it was fucking witchcraft, so who knows.

About 3kW to move 1 ton up one foot in one second.
