NYC to DC in 29 Minutes: the Elon Musk Masterplan

Just yesterday, Elon Musk made a tweet related to his plan of building a Hyperloop from Washington DC to New York City.

Elon Musk states that he received verbal approval at the federal level to build and dig a massive tunnel for his high speed transit system, the Hyperloop. Apparently, the transit system would also stop in Philadelphia and Baltimore. Interestingly, Philadelphia and NYC representative said they've had no conversation with Musk, but...



... the Department of Transportation referred [news outlets] to a White House spokesperson who said there have been "promising conversations" about the project.

What is the Hyperloop?



A Hyperloop is a high-speed transportation system that Musk outlined in a "white paper" in 2013. It would work by shooting pods through a vacuumed-sealed tube at speeds up to 700 mph.

Hyperloop One, a startup independent from Musk's Boring Company, completed the first successful test of a Hyperloop system earlier this month. The pod, however, only reached 70 mph and traveled for 5.3 seconds.

Musk's Boring Company is focused on digging tunnels to support various forms of transportation.

Musk has said the tunnel would be used to transport people and cars via an electric skate.

I'm curious as to what you guys think of this. How would this Hyperloop change your way of life? I'm assuming after it is built individuals can live in DC, Philadelphia, or Baltimore and just commute to NYC in under 30 minutes. Do you think its a plausible idea?

 

I think what's interesting is that Musk estimated that it will take ~7 years to build this. So its not that distant in the future!

I am from Asia and I would also love to see this kind of high speed transportation back and forth Asia and US. I remember about an article of China's interest in building this kind of underwater rail connecting China and US.

 

I love Elon Musk--I'm a huge fan of SpaceX and of Tesla Motors (and Paypal, FWIW). But this is one of those projects that is guaranteed to go nowhere, which is why he's not really spending much of his own money on the project--it's going to be "open source". If Musk thought this was a money maker he'd be all over it financially. The issue is, this idea is bigger than revenue and expense--it would take a massive tax payer investment of capital expenditures and there is absolutely no appetite for it in Washington.

A lot of these CEOs think their wealth makes them "kings of the world", but the truth is, Reps. Eric Cantor, John Boehner, Paul Ryan, etc. don't give a damn about the opinions of wealthy west coast CEOs, hence, this idea is going nowhere.

 

I hear what you're saying, but at the same time look at what he said it would be best for and the estimated cost of this versus the high-speed train from LA to SF. Pretty impressive, I think in some cases it'll be viable.

I'm not an expert on this, but I'm assuming that any project that involves building a pipe/vacuum would involve government approval and all sort of regulatory crap such as eminent domain. SF to LA could be feasible since a lot of central california is farmland, so there's space, but anything on a bigger scale such as NYC to LA is out of the question. As someone who is livid at how slow air transportation is, I badly want to see this get off the ground.

Nah I'm just fed up with businesses that wouldn't be afloat if it weren't for taxpayers lining their coffers.

 

Wondering if there is someone here who understands what the significance of this hyperloop schematic is... Is the reason this doesn't currently exist because of funding and gov't bureaucracy or because nobody knew how to do it until Elon?

Really curious as to what Elon's edge is beyond being intelligent and having a lot of money considering that he didn't even graduate with a degree in engineering.

 

He has a bachelor's in physics from UPenn. He also went to do a PhD in applied physics but dropped out pretty quickly. Probably decided to just learn what he needed.

EDIT: Also, it would be built using mostly existing technology. I'm guessing nobody's done it yet because it'd pretty much only be worth undertaking by a government body. Governments rarely introduce new technology, and this would require a lot of funding for something with no track record.

Really curious as to what Elon's edge is beyond being intelligent and having a lot of money considering that he didn't even graduate with a degree in engineering.

Elon's technical value-add (he claims) was the idea to use a very low-pressure tube, which is a departure from the existing literature on the topic, which propose one of two solutions: 1.) Pneumatic Tubes - High-pressure tubes that shoot the capsule, kinda like those cash-containers you might see at Costco or a retail bank 2.) Vacuum tubes with Magnetic Propulsion - Think the Maglev train in Asia, but with zero air resistance (because it's in a vacuum)

The key problem with both of these solutions is that the energy cost to make a fully pneumatic or vacuum sealed tube is enormous and the danger to passengers if the tube is ruptured in either scenario is too great.

Elon's novel solution is a hybrid method between the two. Essentially, the Musk Hyperloop uses low-pressure tubes (which, again, he is hailing as the key value-add) to eliminate most of the air resistance, coupled with a capsule sitting on a track that is then propelled both through EMP and high-pressure air propulsion. Think of an air hockey table whose puck is also accelerated via EMP and which faces basically zero head-on air resistance.

While less efficient than the even more far-fatched solutions previously discussed, his solution would cost significantly less. I feel like Musk's solution would probably have been proposed by someone else eventually, so maybe take that into account when you try to think about "Elon's edge", but I'm still a huge fan of the guy and think he (and his team!) obviously deserves credit for coming to it first. Dude's a boss.

Awesome break down. +1

 

Whatever Musk is talking about, it doesn't appear to be similar to the VHST if you consider his "air hockey table" comparison. The VHST requires a medium vacuum (0.5 torr) to work. Also, I read the Rand study and yeah, the VHST is a stupid idea predicated on some bigass assumptions that won't work. That being said, I suspect 2013 Musk is far more clever than 1972 Salter, so perhaps the hyperloop will actually work.

"My caddie's chauffeur informs me that a bank is a place where people put money that isn't properly invested."
 

Musk is the fucking man. Jamie Dimon used to be my hero - then I found out about Elon Musk. Always wondered what his hyperloop idea was - thanks for finding this!

 
kingtut:

The G force would only be significant during the capsules acceleration phase. Going from 0-9,000 MPH in less than a few minutes would be quite a ride. Once you hit top speed it wouldn't be any different from cruising in a car or plane.

As long as you don't turn...and go straight through the Rocky Mountains instead of over them.
 
Edmundo Braverman:

ET3 out of Colorado is building a 3-mile version:

http://www.sfgate.com/technology/businessinsider/a...

6-man pods travelling 4,000 mph with only the G-force of an automobile. Incredible.

Interesting, it looks like the prototype planned by ET3 is nearly identical to the VHST in how it functions. I will be very impressed if this works.

"My caddie's chauffeur informs me that a bank is a place where people put money that isn't properly invested."
 

I can't see how they would be able to keep a vacuum along the entire tube. Maybe they would close off and open up sections as the capsule traveled along. But Yea besides during the acceleration you won't feel the speed.

 

I've been following ET3 for quite some time, as when I first heard about the idea I thought it would be terrific. From my understanding, the g-force during acceleration is 1g. The economics of it are pretty sound because: 1.) The cost of construction is significantly cheaper than a highway, and 2.) The energy required at acceleration can be recaptured as the capsules slows down. To me, this idea just reminds me of "The Minority Report."

 

But guysssss, California is already building 'high speed' rail that will be completed in 50 years, cost $100 billion dollars, and may get you there in about the same time as a car. There is no need for any of this technology advancement stuff.

 

Musk has already stated it won't be a vacuum system - check his tweets. He also said its going to be open source... so any other investors out there that want to foot the bill on perfecting development are welcome to chime in once he drops the knowledge on us. Personally, I think Elon Musk is brilliant. He is easily the greatest industrialist of our time.

BlackHat:

This guy... is batshit crazy.

Thanks Blackhat. Guys like you are the reason I've made a boatload of money on Tesla and SolarCity in the past 6 months.

A lot of people gloated about making money on Chemdex, pets.com, mvp.com, FSLR, etc etc and then they wound up getting pummeled.

Musk made his money in software. Building huge, capital intensive corporations is much, much different. The lack of disclosure in their filings about the operations of the business is startling. Why do you think they suddenly stopped publishing their backlog? Maybe because the 4500 cars they are producing each quarter now is significantly higher than run rate demand? Why do you think they’ve run around talking about being profitable when operating earnings were negative? They booked FV gains on DOE warrants and FOREX contracts to get to a GAAP net income number that was positive. The month they were “cash flow positive” was because they didn’t pay suppliers to reduce working capital!

The amount of hope and blind adulation for the founder is higher than in any business I’ve seen in a long time, more so than Facebook even.

 

Gray Fox, admiring and showing adulation for a visionary/founder is a very different thing than owning and believing in the stock at current valuation levels.

I admire Musk and am glad at least someone is trying to shake things up by building huge capital intensive corporations. Does that mean I would own the stock at these levels, or perhaps ever? No, the two are not mutually exclusive things.

Right so Tesla is following the same hype cycle curve that someone else posted a while back, similar to the Gartner one. No doubt Tesla is overvalued, and at some point the valuation will come crashing down.

The ACTUAL growth of the company probably looks more like the blue line here http://s21.postimg.org/4g1zubqqv/J_R_Bubble.png

Unfortunately the market, and humans in general, tend to be bi-polar; valuations are higher than they should be in exciting times, and lower than they should be in depressing times.

As far as building huge, capital intensive corporations, you do know the guy built a profitable fucking rocket company right?

 

The capital required is mind boggling. Additionally, using any system above ground would require significant rights of way and gradual sloping. Trust me, you don't want to make a sharp right going 9k mph. That being said, I welcome this century's version of Union Pacific. Credit Mobileier redux.

kinghongkong:

If you guys have read the original study (I have only read a part of it), you would know that it is INCREDIBLY dangerous. One tiny hole will lead to the vacuum along the entire route escaping within milliseconds. The result? Questionable, but most likely fatal for everybody in one of the vehicles at that moment.

I just read the study and did not see this. I did however see that the author(s) suggested a heat shield be placed at the front of the vehicle as a precaution for the vacuum being compromised while a vehicle is moving. The study says the heat generated moving at thousands of miles per hour though the near-vaccuum is negligible, and only becomes an important consideration when the vacuum is compromised

It is still a bargain compared to the proposed SF-LA high speed rail, which is supposed to cost $69 B but will in all likelihood suffer huge cost overrun and end up costing well over $100 B. Perhaps big government should sub-contract the construction of the SF-LA project to Elon-- If they are going to throw $70B down a sink hole at least make it cool and edgy.

I've always wondered why we don't have trains up to par with those of Asian countries. I know their trains aren't as fast as the ones that are mentioned in this thread but I was wondering why we don't have bullet trains. I've read that some bullet trains are in construction in the US but Japan has had them for years..

 
Edmundo Braverman:

The thing that always comes to mind for me when discussing transportation technologies like this, however, is what effect does it have on a passenger's body? Think about it: you're essentially travelling at 9,000 miles per hour. Is it a comfortable ride, or is the acceleration more like a Six Flags ride on bath salts? Are you liquifying internal organs by subjecting them to that kind of G-force?

Believe it or not the g-force wouldn't necessarily be any more than takeoff on a commercial plane. We're talking about a long distance meaning a relatively long time to accelerate. The fact that you'd be traveling around 8000 mph at some point doesn't really matter as far as forces are concerned.

Is this a serious post? Japan in the size of Southern California. The United States is the size of, ya know, a continent...

There's no economical way to build and maintain bullet trains since the U.S. has the largest and most advanced interstate highway system in the world and little demand for trains. It's not that the U.S. can't, it's that we don't have an economic reason to build bullet trains when you can get anywhere--independently--with your own car.

I believe it not. The g-forces would be very extreme. It might only take just under 3 minutes at 1-g acceleration to reach 9,000 mph, but it wouldn't be possible to travel in a straight line unless you're planning on digging a 3,000 mile tunnel through the earth's crust. A gradual turn over 100 miles at 9,000 mph would be something like 35,000 G's.
 

The way Musk's career is heading, Apple should buy Tesla and make Musk the CEO of the combined entity... Would love to see what his eccentric drive could accomplish with that company and that much cash on the balance sheet. Or is this too crazy, even for Musk?

This hyperloop thing sounds amazing, and I can't wait to see how he believes to pull it off -- making it open-source is even better. Also, for those who don't know, the movie version of Tony Stark's character was based on Elon Musk, for apparent reasons.

 

i have no expertise in handicapping this man's ability to build this contraption, but it is amazing to think that the time to cross the country hasnt changed since the jet engine came into commercial use 50 years ago. Given the post 9/11 security boondoggle it actually takes longer door to door....i actually just a read a book called The Jet Age about the race for the first cross-atlantic jetliner and back in the early days of jet travel they used to advertise that you could arrive at the airport 10 minutes before the flight. This is the stagnation that occurs in highly regulated industries...

 

The time to cross the country by plane has actually gotten slower (although only slightly).

Airlines realized about 20 years ago that one of the best way to keep costs down was to fly at a slower cruising speed. So they actually made the active decision to slow planes down.

I have arrived at airport 10 minutes before flight and still get on airplane no problem... with one carry on only, pre-checked in with boarding pass in hand, flying Southwest out of LaGuardia, arrived in the afternoon where there was hardly anyone at security line so went right through TSA-screener in 2 min right after security is SW departure lounge for Chicago.

While 10 minutes was definitely a little tight it is still possible to get through security to boarding the airplane fairly quickly even in this das and age with some careful planning. Hence he reason I always prefer Southwest to other airlines and LaGuardia over JFK.

Delta Shuttle too has been promoting their streamlined boarding process for NYC-Chicago/Boston/DC routes as a way to compete against Acela (for Boston and DC) and other transportation options. Security is usually a breeze as they have their own terminal at LaGuardia which felt like boarding a private jet.

But yeah the TSA should be abolished. Too bad it is now unionized thanks to Obama and ergo it has become a racket with the self-servicing tendency of justifying its existence and continuous expansions by creating more inconveniences and delays at the expense of passengers.

I think it's pretty safe to assume that at some point along a 3,000 mile trip (maybe closer to 2,500 if it were a straight line), the train would have to turn. Or we could use up all of the world's resources to tunnel through the planet. Whatever.
 

Musk has been touting this for a little while. I thought he originally said SF-LA in 20 minutes. I know he's been saying that it could go from NY-LA, but I didn't realize he was claiming that could happen in 21 minutes.

He's calling this project the Hyperloop and he's going to make it completely open source soon. I believe the date he's releasing it is August 12th, if my memory serves me correctly.

Musk is a badass. Even though I'm too much of a coward to put my $ into his companies (and I now think they're overvalued), the guy is an absolute visionary. The Model S is seriously an awesome car. I'm really interested to see what he releases, but I'd guess that it won't be economically/politically/legally feasible, which is probably why it will be open source. Honestly, even if the Hyperloop was the best thing in the world, how would he acquire a continuous strip of land from NY to LA?

It might only take just under 3 minutes at 1-g acceleration to reach 9,000 mph, but it wouldn't be possible to travel in a straight line unless you're planning on digging a 3,000 mile tunnel through the earth's crust. A gradual turn over 100 miles at 9,000 mph would be something like 35,000 G's.

Um, neither of us know what the exact design would be. I'm simply stating that going 9000 mph doesn't have anything to do with the g force. If you bothered to read the original post I was responding to, the question was what effect would going 9000 mph have on the body. The answer is it depends, just like I said.

I think it's pretty safe to assume that at some point along a 3,000 mile trip (maybe closer to 2,500 if it were a straight line), the train would have to turn. Or we could use up all of the world's resources to tunnel through the planet. Whatever.

Or, the thing slows down to a reasonable speed to make the turn and then speeds up at the straight aways...

 

Question: how many people/vehicles can use this thing at one time? What's it's capacity? 21 minute trip for how many people at one time?

Eddie, I really appreciate that you reference Felix, he's a prime example of a banker that understands how to best use the both the private and public sectors for the best outcome, and everyone walks away with something. I was a fan of Rohatyn before I even knew what an investment banker was, his influence and reputation extend THAT far outside of finance. He's really one of the lone voices of reason in a very crowded field, and he has the track record to back up his ideas. America running better via gov't orchestrating private companies for systemic upgrades....what's not to like?

As an aside, I'd like to quote Lewis Black in reference to TSA and their union: "A Republican says I got a really baaaad idea! and a democrat stands up and says ...and I can make it shittier!"

Looks like you guys have discussed the science here quite a bit. While I'm sure we're a ways off from having this viable, I have to admit I got a little giddy at what this would mean for our personal freedom and our economy if it happened. Taxes to high in California? No problem. We'll move our office to Texas - but you can keep your house in California, just hop on the train for the 10 minute commute.

Eventually I think the concept of cities, states, and even countries would start to become obsolete.

Wouldn't planes or vessels that could go into orbit accomplish super fast transcontinental or international transport as well? And wouldn't that be a far easier and inexpensive technology to master?

I was thinking the same thing. Of course, you'd still have the two hour wait to get through security.

Not sure if this is meant as a joke, but going into orbit is like the most incredibly expensive thing ever. Like for sure 1000x more expensive than the alternatives.

I believe NASA is planning to pay Russia for a couple seats on an upcoming trip to low-Earth orbit to rendezvous with the space station. You could google how much NASA is paying per seat

Yeah, it's more expensive to perfect and make efficient an already existing technology than it is to build a continental tube that goes 9,000 MPH without any turns...

Musk is already on this as well. Check out this launch and landing from a few days ago:

Homeboy's gonna crack the code on this shit one way or another.

 

I would quit my job and shadow Musk for free for a year.

You're born, you take shit. You get out in the world, you take more shit. You climb a little higher, you take less shit. Till one day you're up in the rarefied atmosphere and you've forgotten what shit even looks like. Welcome to the layer cake, son.
 

I read an interesting argument against the hyperloop on California's High Speed Rail blog: http://www.cahsrblog.com/2013/08/hyping-the-hyperloop/

I think this is absolutely awesome to imagine, but my level of physics and engineering is nowhere near good enough to know where the biggest stretches are (besides budget)...

I'd love to hear an impartial evaluation of this proposal, where it's main faults are and what needs to be done to get a prototype set up...

 

Great concept and thorough description of the physics involved. However I would let China build, test, and operate it before pouring money into it ourselves. There's a lot of pieces at play with little room for error. Especially when low pressures and transonic speeds are involved in a large system.

After reading the technical design notes I'm curious to see the criticisms and improvements that will follow after closer scrutiny by the public.

 

I heard that the throughput of the system is its achilles heel. Under a best case scenario it moves only ~800 people/hour. Still nice to see some out of the box thinking. Elon is my hero.

Please don't quote Patrick Bateman.
 

"One very interesting bit: it uses the same type of motor technology as the Tesla S (just in a different configuration) placed every 70 miles. Guess what that means?

Whatever technology you're using to power those motors can also be tapped into to create a charging station for your Tesla every 70 (or less) miles, right along the highway. Get the state/feds to fund the construction, then your private company taps into the infrastructure to develop electric "filling stations." As more Hyperloops are built, a nationwide network of electric filling stations is automatically created without a private company having to foot the bill for infrastructure development.

This guy is a damn genius. Seriously this is the type of thinking that makes the electric automobile a viable future product. Piggy-backing the infrastructure is a very, very good business idea."

Also, from Musk's press conference:

Putting solar panels on the entire Hyperloop tube would generate too much power, Musk says. "You'd have to dump the power somewhere."

"Hmm... Putting solar panels on the hyperloop. Let's see... solar panels... solar panels... What local CA company is great at doing solar panels? Hmm... Oh yeah, Solar City owned by Elon Musk!"

This is what came to my mind as well. Given that people will need to be transported individually from SF to LA (and vice versa) there will likely be a huge backlog of users waiting at the station for their turn of the ride. Sort of like Disneyland on a busy summer Saturday where you end up waiting in line for 3 plus hours for a 30 minutes ride except in this case the line will probably be a lot more extreme. Or maybe they can build multiple hyperloop tunnels so they can shoot several people out at the same time. Elon estimates a hyperloop project to cost around $6b which is around 1/10 of the projected cost of the state of CA's proposal high speed train project between SF and LA so why not divert the $60b so that Elon can build 10 hyperloop stations.

Too late for second-guessing Too late to go back to sleep.
 

Before the travel you will have to sign the disclaimer for death occurrence.

It was all over European news last night. Great idea. I want to see how they implement it. So far whatever Elon Musk touched was golden so let's hope this idea will be too.

Not sure what your line of thought here is on this... I think I remember reading it holds 27 people per car so it's not individually. Even if 800/hr is right, it looks like the number of flights per hour from SFO-LAX is 5 and the biggest jets they will fly on that route will 737s/A320s which hold ~180 people. All flights won't be A320s though, many will be little regional jets for SFO-LAX. So 800/hr on the hyperloop will provide excess capacity throughout the day and at least match demand during peaks. And that's assuming this will completely replace air travel, which it won't.

Do you know how many people drive from the Bay Area to SoCal every day (excluding commercial vehicles)? I don't have the data on this but this is the key demographic that the hyperloop will be targeting, even more so than those who fly.

Also when considering flyers, we need to look at more than just SFO-LAX but all the other airports in both metro areas too, e.g. San Jose, Oakland in the Bay Area and Burbank, Ontario, Long Beach and John Wayne in SoCal in addition to the two biggest ones you mentioned. Not to mention those who fly out of nearby areas like Sacramento, San Diego etc
