Elon Musk reads Nextbigfuture. This was revealed when he referenced a 2018 article on Nextbigfuture which described the $1 billion per mile cost of subways. Boring Company is tunneling and building underground transportation in Las Vegas for $10-15 million per mile.
US subways and tunnels costs of $600M to $4B per mile and most cost $1B/mile.
Europe/Japan subway and tunnels cost $200M-$1B/mile.
Phase 1 of the New York 2nd Ave line, [96th Street, 86th Street and 72nd Street stations and 1.8 miles (2.9 km) of tunnel], cost $4.45 billion. A 1.5-mile (2.4 km), $6 billion second phase from 96th to 125th Streets is in planning as of 2023.
Elon Musks Boring company has its Prufrock-2 tunneling machine. It can dig up to 1 mile/week.
A tunnel the length of the Las Vegas strip (approximately 4 miles) can be completed in a month.
Prufrock-3 is faster, with the medium term goal of 1/10 human walking speed, or 7 miles/day.
If TBC produces 1 new Prufrock machine per month, then TBC will be introducing 600 miles/year of capacity.
Less than 20 miles of underground subway tunnel has been constructed in the US in the last 20 yrs.
One Prufrock-3 machine per month is twelve- 4200 miles/year of capacity. Forty Prufrock-3 machines by 2028 for 10,000 miles of tunnel per year even with some machine downtime.
In thge video, I also talk about the improvements to the SpaceX rocket engines, which will enable a larger Super Heavy Starship. A Starship could increase internal volume from 1000 cubic meters like the International Space Station up to nearly 2000 cubic meters. The Super Heavy Starship will also be able to launch 250 tons in fully reusable mode.
The International space Station weighs 450 tons. A reconfigured new version of the Space station could be launched in two trips of a stretched Super Heavy Starship with better engines. It took more than 50 flights of the Space Shuttle to bring up all of the parts for the Space Station.
