Elon Musk is nothing if not ambitious.

The billionaire tech entrepreneur who co-founded PayPal in 1998 and sits at the forefront of a whole bevvy of industries as the CEO of both electric car manufacturer Tesla and private space flight company SpaceX now claims to be in the early stages of another breakthrough--this time in the world of mass transit.

In a recent interview with Bloomberg Businessweek, Musk--who director Jon Favreau has said was the inspiration for his take on Iron Man industrialist Tony Stark--talked a little about his newest project:

On the assumption that people will be living on earth for some time, Musk is cooking up plans for something he calls the Hyperloop. He won't share specifics but says it's some sort of tube capable of taking someone from downtown San Francisco to Los Angeles in 30 minutes. He calls it a "fifth mode of transportation"--the previous four being train, plane, automobile, and boat. "What you want is something that never crashes, that’s at least twice as fast as a plane, that's solar powered and that leaves right when you arrive, so there is no waiting for a specific departure time," Musk says. His friends claim he's had a Hyperloop technological breakthrough over the summer. "I'd like to talk to the governor and president about it," Musk continues. "Because the $60 billion bullet train they're proposing in California would be the slowest bullet train in the world at the highest cost per mile. They're going for records in all the wrong ways." The cost of the SF-LA Hyperloop would be in the $6 billion range, he says.

Speaking with PandoDaily at an event earlier this year, Musk explained that Hyperloop, which essentially resembles one of those people-moving tubes from futuristic cartoons like the Jetsons or Futurama, would cost significantly less per ticket than traveling from San Francisco to Los Angles by plane or using the long-in-the-works bullet train that initially inspired Musk to dream up the project in the first place.

Musk has said he's looking into patenting the idea and then open-sourcing the license to someone who looks like they have the resources and technical know-how to build it.

The promise of this new technology and multi-decade lead time of the completion of California's increasingly controversial high speed rail project has led NBC Bay Area's Joe Matthews to wonder if California's bullet train will be obsolete by the time it's finished being built. "It's a reminder that the world changes fast, and technology is advancing," wrote Matthews. "And a state that bets tens of billions of dollars on a technology--high-speed rail--that is already old could be making a historically bad bet."

Not everyone is so optimistic about the transformative potential of Musk's idea. "The fastest maglev speed recorded is 361 mph, well short of the 900 mph this tube idea would require," wrote bullet train booster Robert Cruickshank on the California High Speed Rail Blog. "Supersonic aerial transport has been tried, namely with the Concorde, but the operating costs were too high and it proved to be extremely difficult to get permission to operate it over land (which is why it primarily served a trans-Atlantic route). I suppose there might be some way to hit 900 mph in a tube but I have no idea what that would be."

"I'm not trying to harsh on Elon Musk’s idea, but this is not particularly realistic," added Cruickshank. "Sure, there's been a lot of technological innovation over the last 20 years, but it's led to the iPhone, not to a series of transportation tubes."

No matter what happens with the Hyperloop, California's high speed rail project remains on track.

Earlier this month, the Federal Railroad Administration gave the green light to start the first phase of construction, a segment between Fresno and Merced in the state's Central Valley. The groundbreaking for that 65-mile stretch of track is scheduled for next year.
This guy's certifiably insane. And that's awesome. I'd love to see him make this work.
 
He reminds me at times of Tesla. He invents stuff, is not limited to a single field of expertise, and is generally awesome. Go Musk!
 
Sounds cool! Sounds very much like pie in the sky ATM, but if something like this ever did happen it would be awesome!
 
I'm not trying to harsh on Elon Musk’s idea, but this is not particularly realistic - Robert Cruickshank

I can see someone setting himself up for that list of infamous quotes:

"There is no reason anyone would want a computer in their home." -- Ken Olson, president, chairman and founder of Digital Equipment Corp. (DEC), maker of big business mainframe computers, arguing against the PC, 1977

"If anything remains more or less unchanged, it will be the role of women." -- David Riesman, conservative American social scientist, 1967

"We don't like their sound, and guitar music is on the way out anyway." -- President of Decca Records, rejecting The Beatles after an audition, 1962
 
"I'm not trying to harsh on Elon Musk’s idea, but this is not particularly realistic," added Cruickshank. "Sure, there's been a lot of technological innovation over the last 20 years, but it's led to the iPhone, not to a series of transportation tubes."

This sort of thinking irritates me. His argument is that it can't work because we don't already have it, instead of waiting for Musk to reveal the idea in full before disputing it.
 
so ? is this similar to those little tube things they still use in some banks, to get money papers from one location to the next ?
 
Will it be fair to call him South African? He did go to school here... :)

Probably. I'm just curious as to what propulsion mechanism he has in mind...
 
My guess is the use of Maglev and Coil Gun technology.

http://en.wikipedia.org/wiki/Maglev#Propulsion
The power needed for levitation is not a particularly large percentage of the overall energy consumption; most of the power used is needed to overcome air resistance (drag), as with any other high-speed form of transport.

To fix that problem you pump all the air out the tube so there is no resistance.

Using a magnetic field powered by electricity, a rail gun can accelerate a projectile up to 52,493 feet (16,000 meters) per second.
( 16000 meters per second = 57 600 km/h ! )
I think the biggest problem will be not to kill the passenger with G forces.

What are you going to do for 30 mins? This sounds quite claustrophobic to me and the idea of being placed in a tube at 1600km/hr sounds terrifying. I think he might make it work and it will last until the first fatal accident.

And yet we still have planes in the sky.

Acceleration and deceleration can be smooth and gradual.

The centripetal forces also won't be a problem with large radius turns.
Someone with a mass of 100kg moving at 900 MPH (402 meters/second) would experience 1.64G's in a turn with a radius of 10km.
 
I hope he succeeds and turns his vision into a reality. The world needs more people with "crazy" ideas.
 
He says there is no need for rails... To pump large amounts of air out of a tube that long would be impractical if not impossible. Also it sounds like it is personal transport to some extent (leaves when you arrive) but mass transit since it is to replace a train. The speeds seem ambitious too. Would that speed not make it the fastest thing on land? At that speed it would actually create a sonic boom. Again not practical.

The fact that it is a "loop" makes me think that trains only run in one direction ie clockwise in a giant "ring." The best thing I can think of is a maglev type system that is suspended rather than traditional train on rail and I assume the tunnel will be there to create some sort of drag minimising/ air boosting effect. Perhaps an aerodynamic pod uses the tunnel to create a sort of "scram" jet.
