Imperial Valley, CA · $115B (proposal)
SLT-24 · Imperial Valley Salton Sea Inversion Aqueduct
Four hundred miles of 5-meter-diameter pipe carry desalinated coastal water inland to refill the dying Salton Sea — transforming a shrinking toxic dust bowl into a managed freshwater reservoir ringed by vertical farms.
Pros
- Addresses a real public-health emergency: the Salton Sea's exposed playa already generates toxic dust storms.
- Pairs water delivery with food production — the vertical agri-domes make the economics less one-sided.
- Desalination plus solar power is a proven combination in the Middle East and Australia.
Cons
- Pumping water 400 miles inland is an enormous permanent energy tax — the physics never stops billing.
- Desalination brine disposal at the coast is its own environmental problem.
- $115B to refill one lake invites hard questions about cheaper dust-mitigation alternatives.
Feasibility: The most debatable cost-benefit on the list. The Salton Sea crisis is real — California is already spending billions on dust suppression. But 400 miles of 5-meter pipe is a monumental build for a single basin. A serious version of this project would start with the question the proposal skips: what's the minimum water needed to stop the dust?
Aerial mock-up: A buried 400-mile pipeline (a linear construction scar, then invisible); at the terminus, the Salton Sea reborn as a freshwater reservoir bordered by vertical agri-domes.
