IE what are the areas we should be seeking to migrate as many people as possible to before shtf.
I mean that’s a good way to spend excess renewable energy, keep it in a reserve of water at the top of a mountain when there’s excess energy, use power turbines to recapture the energy when it comes down.
That is usually done with 2 nearly-adjacent reservoirs on a mountainside, where you only have to install a couple hundred meters of pipe. It’s completely different from something that would run all the way across a continent.
What you are suggesting is that we create a river that runs uphill, powered by the electric grid. It’s not very feasible. Canals make sense but this does not.
