Is it plausible to build a tunnel from China to the US through the ocean? Just a wild idea.

Is it plausible to build a tunnel from China to the US through the ocean? Just a wild idea.
- Someone 5y agohttps://en.wikipedia.org/wiki/Transatlantic_tunnel https://en.wikipedia.org/wiki/Transatlantic_tunnel: “The main barriers to constructing such a tunnel are cost first estimated $88–175 billion, now updated to $1 trillion-20 trillion, as well as limits of current materials science.“ China-USA would be a bit longer and go through the ring of fire (https://en.wikipedia.org/wiki/Ring_of_Fire https://en.wikipedia.org/wiki/Ring_of_Fire), making it a bigger challenge to build. I would guess a bare tunnel itself is less of a challenge than its ventilation (even if you build a parallel tunnel tube for ventilation, pumping it out over thousands of kilometers will be challenging. The alternative would be to build ventilation towers every x km) and safety (how long will it take to get an ambulance to a traffic accident? To get people out?)
- samstave 5y agoA semi-bouyant tunnel that sits ~100 meters below the surface with anchors to the floor and floats above might be ideal. Imagine if it was a conveyance even for just "packets" (cargo conatiners that are shot through the tunnel, no humans...)
- noahtallen 5y agoThe next downside is whether anyone would use such a tunnel, given that plane travel would be much quicker, probably safer, maybe cheaper (tolls on such a tunnel plus gas would be quite expensive), and possibly more enjoyable (better views in a plane, it’d probably be depressing and claustrophobic being down under for so long)
- barbecue_sauce 5y agoI imagine it would be used for shipping primarily.
