Elon Musk’s Las Vegas Loop might only carry a fraction of the passengers it promised

Quote:
In pandemic-free years, America’s biggest trade show, CES, attracts more than 170,000 attendees, bringing traffic that jams surrounding roads day and night. To help absorb at least some of the congestion, the Las Vegas Convention Center (LVCC) last year planned a people-mover to serve an expanded campus. The LVCC wanted transit that could move up to 4,400 attendees every hour between exhibition halls and parking lots.

It considered traditional light rail that could shuttle hundreds of attendees per train, but settled on an underground system from Elon Musk’s The Boring Company (TBC) instead — largely because Musk’s bid was tens of millions of dollars cheaper. The LVCC Loop would transport attendees through two 0.8-mile underground tunnels in Tesla vehicles, four or five at a time.

But planning files reviewed by TechCrunch seem to show that the Loop system will not be able to move anywhere near the number of people LVCC wants, and that TBC agreed to.

Fire regulations peg the occupant capacity in the load and unload zones of one of the Loop’s three stations at just 800 passengers an hour. If the other stations have similar limitations, the system might only be able to transport 1,200 people an hour — around a quarter of its promised capacity.

If TBC misses its performance target by such a margin, Musk’s company will not receive more than $13 million of its construction budget — and will face millions more in penalty charges once the system becomes operational.

Neither TBC nor LVCVA responded to multiple requests for comment.

Elon Musk’s Plan to Dig Car Tunnels Under Miami Is Filled With Holes

https://www.curbed.com/2021/01/elon-...g-company.html

Quote:
.....

- Last weekend, Elon Musk claimed that he’d had a conversation with Florida Governor Ron DeSantis about his Boring Company project, which builds very short, very small tunnels for cars. “Cars & trucks stuck in traffic generate megatons of toxic gases & particulate, but @boringcompany road tunnels under Miami would solve traffic & be an example to the world,” he tweeted. — “If Governor & Mayor want this done, we will do it.” This was at 4 a.m. Miami time, but almost immediately, the city’s mayor, Francis Suarez, tweeted his approval: “Count me in,” he said, calling Musk’s plan a “no brainer.”

- Let’s consider that there might be a reason why Miami doesn’t have a subway. Or why many of its homes are built without basements. Or why the city has already spent hundreds of millions of dollars just to make its streets navigable to cars today, building a pump system to mitigate the flooding Miami now faces even when no storms are on the horizon. — Part of the motivation behind Suarez’s sycophancy may be that he’s trying to reinvent Miami as a tech utopia by wooing remote-working founders newly untethered from corporate campuses. Musk’s arrival would be yet another selling tool to lure startups away from Silicon Valley.

Which tunnels do exist in Florida and when were they built?

There is one under Miami Harbor. It opened in 2014:

Will these tubes be mostly for the 1%? Probably but anything that gets this wasteful carbon-intensive group of people onto a more sustainable path is still probably a good thing especially if it doesn't cost taxpayers cash. Or at least that's the vision pitched... A toll road future... Still waiting for those Tesla buses though...

Musk's tunnels don't have ventilation (part of the supposed cost savings) so they can only be used by electric vehicles or other emissions-free tech. If Musk can build Tesla buses that provide a reasonable capacity and are durable enough for heavy public use, then I'm all for this... but the Vegas example shows he doesn't really want to do anything except build dedicated underground roads for the fancy cars he already produces.

Wonder if this actually gets built...

I know that Brightline plans to (eventually) send their proposed HSR from Victorville to Rancho's Metrolink station. Maybe this is an attempt to "link" that to ONT?

Since San Bernardino is more open to private firms like Hyperloop than say LA or OC, maybe this actually gets built???

I agree 100%. Also why The Boring Company was hiring staff at Adelanto. I am guessing an LA to LV tunnel with Prufrock is going to be the tech's coming out party as it were... And most likely a race against Brightline to get to the city first since Musk seems to be all about disrupting the status quo, even if it's just a mindset like "America needs to copy the world instead of leapfrogging it"

Personally my compromise/ideal tech would be something I call "MuskMetro" an automated battery-electric Skytrain-like rapid transit that could use the same 12' diameter tunnels as TBC has designed.

If you think the tunnels are too small for rapid transit let me remind you the London Underground Deep Tube network uses tunnels with a smaller diameter than that! So already MILLIONS are transported daily narrower tunnels using tech invented LITERALLY 2 centuries ago...

A) Any kind of lengthy tunnel from LA-LV will have to undergo the notorious California environmental review under CEQA, which takes years. Brightline already has theirs done. There will be no race.

B) Even with the small diameter, tunnel boring is very slow. If you want to speed up a long tunnel, you need to break it up into multiple segments with multiple access shafts and multiple TBMs working at the same time. When Musk wanted to tunnel in Chicago from downtown to O'Hare it was estimated to be 3 years of tunnel boring, and that's only ~16 miles. There will be no race.

C) Musk's tunnels can theoretically carry subway trains ala London Tube, but they don't have traction power, tracks, signals, high capacity stations, rolling stock, or trainyards, and those aren't cheap. Once all that is factored in I don't know if there is much of a cost savings over "reasonable" costs for a traditional subway (i.e. the subway costs paid by Asian and Euro nations, not the US where all construction is subject to cost disease).

D) The face that Musk's tunnels can theoretically carry trains is a moot point, because Musk hates trains (too socialist for him) and he will only build the tunnels for private luxury pods, which is to say Tesla cars.

E) Musk's Vegas tunnel deliberately did not comply with NFPA130, the fire code that applies to subway tunnels. NFPA is a very costly approach to fire prevention and exceeds what is done in Asian and Euro nations, but it is the law of the land in virtually every state. In Vegas, the city and/or state may just decide to repeal that code, which is their prerogative, but fat chance of that happening in California.

F) Finally, the cost savings of Musk's tunnel can't be adopted by others looking to build a subway, because of the NFPA130 reason listed above. So until the code changes nationally, don't expect so see The Boring Company building a subway anywhere.

I'm just speaking for myself here but if I'm on a future subway train and it derails, destroying the third rail and causing a noxious, life threatening and blinding smoke from the arcing, I know the first thing I'm going to say is thank goodness the state didn't follow those silly NFPA guidelines.

It's quite telling that the Tesla autopilot can't be trusted to navigate this closed environment.

They plan to have 62 dudes drive 62 cars. Those same 62 dudes could have driven 62 city buses or 62 subway trains.

Atlanta's airport terminal shuttle has been in driverless operation for 25 years using cables.

And a single file underground highway at that.

Zaha Hadid Architects allies with Hyperloop Italia to reshape the future of rapid transit

https://www.stirworld.com/see-news-z...-rapid-transit

Quote:
.....

- Unveiling a groundbreaking new venture that “marks a turning point for the future of transport and mobility”, Zaha Hadid Architects has entered into a partnership with Hyperloop Italia to co-design its next project phase. The London-based architecture and design firm, known for their progressive, fluid, convention-defying architecture, rooted in the principles of parametricism, brings a wealth of experience in designing large scale architectural and mass transit projects. --- Patrik Schumacher, Principal of Zaha Hadid Architects, states: "We are looking forward to collaborating with Hyperloop Italia; marrying transformative architecture, engineering and urban planning with the most efficient and sustainable transport network to significantly improve accessibility, connectivity, and well-being in our cities”.
