A country like America in the '60s, '70s, or maybe even '80s would build this in a heartbeat. A country like America today...who knows? This plan has the perfect mix of reasonably practical yet slightly unsettlingly new and unfamiliar. It is just the sort of thing that meaningfully evolutionary changes are built on, like airliners or cross-country trains or steam-powered ships. If America builds this, great! If not, watch for which country does and move there post-haste!
