Exactly. HOW does one build a tunnel that constantly needs to expand?

Don't know.

The route was suggested by the video. The Holodomor was perpetrated by a communist government, like the Uyghurs today. Maybe through Russia to Europe? In any case a gated entrance wold be no worse than surface transport.

My concern is what happens to the endless stream of containers when one gets wedged sideways like the Evergiven.

Kinda difficult to compare container transport in a tunnel which should have maintenance tunnels to a one shot incident in a place which wasn't built to specific design. The other issue was the forces causing the blocking pushed the ends about 100ft further into the mud. Had to dig it out or have a 10ft tide to refloat. SISI cost cut the project, and they shouldn't allow ships that are wider than the channel they dug.

Hyperbolic example.

"My concern is what happens to the endless stream of containers when one gets wedged sideways."

The design has four tunnels, two for cargo and two for peeps, one in each direction. If one tunnel is blocked (tectonic shift) the opposing traffic tunnel would have to be cleared AFAIK.

If they are near each other, I suppose all the tunnels will experience the tectonic shift and become non useable. Real time detection and container stoppage would be the issue. However the Chunnel seems to have avoided all this although it doesn't have a seismic component but the SF bay metro system does.

It's a start. Then, what do you do about it? The Chunnel has a third tube.

When trains derail they have someplace to go. Just spackling over an offset in the tunnels won't cut it.

The powerline interconnect might be the best, only one tunnel needed.

Less off-topic:



In the main presentation he mentions solid state batteries currently shipping,
Plasma Kinetics and Light Activated Hydrogen
and Where's My Flying Car?. See his prediction for 2096, flying cars turn out to be VTOL Robotaxis.

In the Q&A

Cooling is important for battery vehicles
He likes the Protean wheel motor, especially for VTOLs
Bluetooth sensors eliminate wiring (Ecomodders be aware)
Respect to Aptera and Arcimoto
