Here is a surprisingly relevant video for you to consider:

It even begins to make fun of the hyperloop idea at the end!

The point of the video is that, while many clean-slate ideas have inherent advantages over current tech in the theoretical world, in practice incremental improvements to existing infrastructure are usually better.

Sure you can have super fast aero-trains or even maglevs, but there are already train stations in downtown areas, and with a few tweaks slow trains can become fast ones. It's the whole "80% of the benefits from 20% of the costs!" philosophy.

Proponents of 1,000 km/h hyperloop duorail pushing for Calgary-Edmonton link

http://calgaryherald.com/news/local-...onton-link/amp

Quote:
.....

- Calgary would be a development hub for an eventual hyper-fast transportation link between the city and Edmonton if a Toronto-based firm has its way. The feasibility of a so-called hyperloop system, which would leave a Japanese bullet train in its magnet-propelled and levitated dust, could be proven at a six-kilometre-long test line in the transportation utility corridor on the city’s east side, said Sebastien Gendron, CEO of tech startup TransPod. — If all goes well and $6 billion of private sector-government investment falls into place, the elevated line would traverse 300 kilometres in central Alberta to connect the province’s two largest cities by the middle of the next decade, said Gendron.

To my mind, the potential advantages of Hyperloop or other private gadgetbahns have nothing to do with technology, and everything to do with privatization. If Elon Musk can truly bring tunnelling costs down by 90%, that's a revolution in itself regardless of what's actually in the tunnel.

Unfortunately, existing railroad systems are led by governments, and while they do usually have the best station locations and rights-of-way, any incremental improvements have to be carefully negotiated among community groups, organized labor, environmentalists, consumer advocates, and a whole mess of other so-called "stakeholders", the result can increase costs by an order of magnitude. For example, the amount that Caltrain is spending to electrify its corridor is insane. LIRR in New York is spending billions to add a third track for only a few miles. It just doesn't make sense.

Elon Musk and other promoters (maglev, etc) are betting that even the high costs of R&D on a brand-new technology can be outweighed by the cost savings of keeping the whole thing private. Of course, as we've seen in Texas, private enterprise is not immune from government meddling, even conservative governments love to meddle if a particular enterprise doesn't quite fit with their handful of favored industries.

The Boring Company has 'won' the right to build an express transit line between downtown Chicago and O'Hare airport:

https://www.theverge.com/2018/6/14/1...-cost-estimate

I say won in quotes because they will get zero public dollars to do this; Elon and his companies are going to foot the bill themselves. When it opens in 3 years, you will be able to take a 12 minute ride between the two points for $25 dollars. You will board a vehicle based on a Tesla Model X that can carry 16 seated passengers; these will depart as frequently as 2 per minute, and will reach speeds over 100 mph.

Elon tweeted a video of a Model X in his test tunnel in LA, sporing horizontal guide wheels on its front and back similar to what a guided bus uses:

https://electrek.co/2018/06/14/tesla...ompany-tunnel/

That doesn't translate into a particularly impressive passengers-per-hour rate since 16 passengers*2 trips per minute *60 minutes per hour = 1,920 people per hour, though I suppose at $25 per ticket they may not get much more demand than that.

The most interesting part of this is that Elon expects the 18 mile tunnels will cost no more than $1 Billion. This would mark a significant breakthrough in the cost-per-mile of tunnels for transit. A large part of this is that he is narrower tunnels than what is used for subways or buses, but other efficiencies like automating much of the tunneling process and speeding up the actual digging part are also bringing the cost down.

If he can get the cost of tunnels down, I'm all for it. I'm not sure about his loops idea yet, but I can see enough potential that I'm not going to make fun. I am extremely impressed that he is actually building something serious now - something the public will potentially use one day. I wish him and the Boring company the best. Happy digging!

Yeah and he pulled that figure out of his ass. It is true that upwards of half of a subway project's cost can be the stations, which are usually a box structure that must be built by traditional excavation, and his express tunnel has no planned intermediate stations.

He's going to have to build a large underground structure at O'Hare right next to the existing blue line subway station. No boring machine can do that. It's going to be horrendously expensive. The alternative is to build a station out in the parking lot - where passengers will have to take a shuttle bus to the terminals. So passengers will get to the airport grounds faster than the blue line but they won't actually get to the terminal any faster.

The most logical scenario would be to build the O'Hare station in the basement of the new Terminal 2. That isn't set to be done until 2026... which is a must more realistic date for this project anyway.

No, it won't be anywhere near the O'Hare Blue Line station. It will be a brand new station, that will be built near the currently proposed new Global Terminal that is being built under the O'Hare Modernization Plan.

Thanks, I missed that important detail. That makes a lot of logistical sense, but I fear that Musk will push the cost of this station onto the airport and/or the city and not include it in his total cost of the project when and if he advertises for another transit job in another city. He's already getting a "free" sort-of completed subway station in the heart of downtown Chicago. That station was built for traditional rail and so he's going to have to design his mysterious system around pillar placement, etc.

The Boring Company will build a rapid transit system to Dodger Stadium

https://www.engadget.com/2018/08/16/...y-dugout-loop/

Quote:
.....

- Elon Musk's company has announced that it's planning to dig a tunnel that leads to Dodger Stadium for a high-speed electric transportation network called the Dugout Loop. The Boring Company is still in the midst of deciding where to build the system's departure point and considering three neighborhoods in particular: Los Feliz, East Hollywood and Rampart Village.

- It plans to sell $1 tickets with fixed departure times for the four-minute ride. Passengers can drive, walk or bike to the departure point and then ride one of the system's 8- to 16-passenger pods to the stadium when it's their turn. Those electric pods, which are capable of traveling at 125 to 150 miles per hour, will then either go back for more people or stay at the arrival point, ready to take passengers back.

Fine with the idea, but dont see how the math works out. 1 dollar rides? I think at best they might get $20,000 on game days.

It might make more sense to have a couple stops along the way to draw more passengers that would use the rail outside of game days, though that does add considerably to the up-front cost.

I think its just a test run for a larger system. I actually think that if this works, it would be a great way to fill in the gaps from the trunk rail systems to destinations. For example... Rose bowl to Gold Line, Hollywood Bowl to Red line, Purple line to the Grove / Farmers Market, Crenshaw line to Inglewood, Etc.

I'm sure "funding is assured" for this too. But Elon might have to plan it from jail:

SEC Sends Subpoena to Tesla in Probe Over Musk Tweets
By Emily Glazer in Los Angeles, Mengqi Sun in New York and Dave Michaels in Washington
Updated Aug. 15, 2018 7:35 p.m. ET

Federal regulators have subpoenaed Tesla Inc., ramping up an investigation into Chief Executive Elon Musk’s tweet last week that he had secured funding to take the electric-car maker private.

The subpoena from the Securities and Exchange Commission seeks information from each of Tesla’s directors . . . .

The subpoena indicates senior SEC officials have authorized a formal investigation of the company, a step up from the initial inquiries the regulator made to Tesla last week. The SEC opens formal investigations when it thinks that a violation of law has occurred and that a probe is justified given the nature of the suspected misconduct and the potential harm to investors.

Under U.S. law, companies and corporate officers can’t give shareholders misleading information about meaningful company events . . . .

He's at risk of losing most of his fortune, since so much of it is tied up in Tesla stock, a company that might be in receivership a year from now.

Elon Musk Details ‘Excruciating’ Personal Toll of Tesla Turmoil
By David Gelles, James B. Stewart, Jessica Silver-Greenberg and Kate Kelly
Aug. 16, 2018

Elon Musk was at home in Los Angeles, struggling to maintain his composure. “This past year has been the most difficult and painful year of my career,” he said. “It was excruciating.”

The year has only gotten more intense for Mr. Musk, the chairman and chief executive of the electric-car maker Tesla, since he abruptly declared on Twitter last week that he hoped to convert the publicly traded company into a private one. The episode kicked off a furor in the markets and within Tesla itself, and he acknowledged on Thursday that he was fraying.

In an hourlong interview with The New York Times, he choked up multiple times, noting that he nearly missed his brother’s wedding this summer and spent his birthday holed up in Tesla’s offices as the company raced to meet elusive production targets on a crucial new model.

Asked if the exhaustion was taking a toll on his physical health, Mr. Musk answered: “It’s not been great, actually. I’ve had friends come by who are really concerned” . . . . some board members have expressed concern not only about Mr. Musk’s workload but also about his use of Ambien, two people familiar with the board said . . . .
https://www.nytimes.com/2018/08/16/b...iew-tesla.html

This article was enough for stock maven and CNBC host Jim Cramer to argue Musk needs a medical leave of absence . . . immediately.

There are hedge funds going short the stock right now and betting it could go to zero.

That may be true, but he's still not going to jail. Worst case scenario is some sort of fine that's insignificant in relation to his net worth.

And it's most likely nothing happens. Elon Musk is pretty much teflon. He rivals only Donald Trump in terms of constantly saying absolute BS and still having an army of rabid fans willing to proclaim him the best thing since sliced bread.
