I mean, if you don't care in the slightest about cost of the plants, the energy required, the land needed to run the giant tunnels... maybe? It's probably technically possible within the constraints of "I have a full country's resources available and can demand they be used to satisfy my absurd requirements and won't face huge blowback for using resources this way." But you can pencil it out. Cuts next year are 2-4 million acre feet of water. What would it take to bring that in? An acre foot is 325,851 gallons, give or take. So, four of those is ~1.3e12 gallons of water for a year. A year has 31,536,000 seconds, so you're looking at a mere 41,000 gallons per second, or about 6500 cu*ft/s. Which is a good sized river's flow. It's also 155 m^3 of water per second, or about 3.5 billion gallons a day. I'm seeing [0] a plant in San Diego running 50M gallons a day on 35MW, so you'd need ~70 of those plants (or about 2.5GW) to manage your water supply. California's purring away at 33GW right now, so the energy required, while massive, is feasible. Trying to figure out how to move 40k gallons a second a distance of 1000 miles exceeds my physics skills, but you could probably figure it out with the right calculators or CFD handwaves. But it's not going to be cheap. Seems... somewhat easier to reduce demand, though. [0]: https://www.energy.gov/sites/default/files/2019/09/f66/73355... |
