Re: Elon Musk is boring a tunnel to skirt gridlock
#202Ok, so one thing I've noticed reading the 120 comments in this thread and the article is that literally nobody knows anything about boring, or tunnels. Musk knows nothing, he put someone in charge who knows nothing, the reporter knows nothing, and the commenters here even admit they are completely guessing and know nothing about boring/tunnels. I definitely don't know anything about tunnels. It's a joke that came to…
I'm not surprised that people who design boring machines or design tunnels are not regular readers or commentators here on HN :-). Like Musk, I've felt that tunneling is under utilized (unfortunately I don't have the resources he has to bring to bear on it) but there is a wealth of information out there on the current state of tunneling. Three interesting projects that have a number of 'explainers' and various papers…
I have worked on tunnels ranging from the smallest to the largest, rock to soil, and all forms of construction.
I have stopped commenting on any tunnel related Elon topic due to people refusing to believe my experience and expertise when it does not align with what Elon Musk and his team of "experts" have said or published in their desk studies.

#203That will totally work.

I design both boring machines and tunnels and am a regular reader on HN. I have worked on tunnels ranging from the smallest to the largest, rock to soil, and all forms of construction. I have stopped commenting on any tunnel related Elon topic due to people refusing to believe my experience and expertise when it does not align with what Elon Musk and his team of "experts" have said or published in their desk studies.
EDIT:
"New machines normally cost at least $15 million, but a decade of frantic subway construction in China has created a glut, and lightly used models can be had for 90 percent off sticker."
I could Kickstart a tunnel boring machine purchase. What a time to be alive.

I've never had any issues with Amtrak's service. People forget that they're second-class citizens to freight on the track, so they're usually not to blame for being late and they're held back by the infrastructure, which is designed, owned, and maintained by freight companies. I know it's accepted in the HN community to be down on government monopolies, but a quick glance at the privatization disaster of British Rail…
I'm not at all discounting your point, but isn't Japan's rail system made up of various private rail companies? Or are those quasi governmental?

Say what you will about BR privatization, but this[0] goes from London to Manchester in 2 hours (takes about 3 by road if you really push it on the M6 toll and M40). They also serve (overpriced) beer. [0] https://en.wikipedia.org/wiki/British_Rail_Class_390
If Amtrak owned the rails and leased to freight, instead of the other way round, I imagine it'd have a similar level of service. As things stand, there's zero incentive for the track owners (freight companies) to update the lines for speeds higher than they can cheaply ship at.
FWIW, I live in Croatia and even we have tilting trains these days. It's downright embarrassing that the US is so far behind.

The US can easily afford to maintain it's infrastructure. It would make money in doing so. Expense is not the reason the US has infrastructure problems.
Yes and no. The US is rich enough to where, yes, we could raise taxes and fund infrastructure better. At the same time, some forms of infrastructure have been over-built. We've demonstrated a massive preference for (wide) roads over walking/biking/transit, and it turns out supporting mostly single-occupancy vehicles as the default transportation mode is extremely expensive. For example, take this blog post analyzing…
It isn't necessary to raise taxes; reducing military spending would more than suffice.

If you're already on top of caverns, the tunnels might actually be able to stabilize and reinforce the ground. In theory... the actual digging would undoubtedly be complicated by caverns.

#210I thought the current thinking was that building more roads means that there will be more roads to use, and therefore more cars on the road. https://en.wikipedia.org/wiki/Induced_demand
