Futuristic High-Speed Tube Travel Could Take You From New York to LA in 45 mins
Quote:
Traveling across the country or the world via any modern mode of transportation is a time-consuming affair. It can also be really annoying with the long lines, crying babies, armrest hogs, cramped space, etc. Would it not be the most awesome invention ever if some new type of transportation could cut that travel time significantly?
Get ready, because it may only be a few years from becoming a reality. A company called ET3 has plans in the works for the Evacuated Tube Transport, a high-speed transportation tube that uses magnetic levitation. The ETT can travel at speeds of up to 4,000 miles per hour, and each tube seats a maximum of six people and comes with a baggage compartment. How does it go so fast? It's airless and frictionless and could have you from New York to Los Angeles in 45 minutes, as opposed to the nearly five hours a direct flight would take. It could even have you depart from New York and be in Beijing in two hours.
The tubes would be set up like freeways to prevent crowding and traffic congestion problems. Plus, ET3 claims that passengers need not worry about feeling discomfort while traveling at such high speeds. The high velocity at which the tubes move is equal to 1G of force at top speed, which is similar to the force felt by someone traveling in a car on the freeway.
Daryl Oster, the founder and CEO of ET3, says that he got the idea for the tube transport system when he visited China back in the 1980s.
When and if the tubes make their debut in the next decade, they will initially be used to transport cargo, not people.

We cant even get an oil pipeline built in BC. No way we are getting one of these tubes. The tree huggers would be up in arms with the risk of a leak with people spewing out all over the environment.
so they plan to lay these tubes up along the west coast, through alaska, russia and into asia... damn.. that will take 30+ years and trillions of dollars... lol.. yeah right...
if they cut through the ocean, theres storms and shit.. go underwater, all the big whales and other sea mammals will bump into it.. not a good idea...
We Think We Know What Elon Musk's Hyperloop Is, And How It Can Get You From LA To San Francisco In 30 Minutes
Tesla founder Elon Musk has been teasing an exciting idea for a new form of transportation for the last year.
He calls it the "Hyperloop" and he says it's better than a bullet train. The Hyperloop would get people to Los Angeles from San Francisco in 30 minutes.
However, he's been vague about how he's going to make the Hyperloop a reality.
The closest to detail he's gotten is when he said the Hyperloop is a "cross between a Concorde, a railgun and an air hockey table."
He's been so vague that it seems like what he's talking about can't possibly be real.
But it can be real.
In 1972, the Rand Corporation released a paper written by physicist R.M. Salter that detailed an underground tube system that could send people from Los Angeles to New York City in 21 minutes.
He called it the Very High Speed Transit System, or VHST. (Not nearly as catchy a name as Hyperloop.)
Salter concluded in his paper that "the technical problems associated with the VHST development are manifold and difficult — but no scientific breakthroughs are required."
In other words, the VHST isn't just some far-out dream. It can be a reality if we address some political and construction issues.
"The general principles are fairly straightforward: electromagnetically levitated and propelled cars in an evacuated tunnel," wrote Salter.
The VHST would be a vacuum sealed tube buried underground that would zip across the country. Salter suggested making a few stops across the country because it would be more practical. It would also allow for other tube routes.
We've emailed Musk asking if his Hyperloop is similar to Salter's idea. He has not written us back. But, reading Salter's paper, it's easy to see similarities to a railgun/air hockey table style transporter.
Salter explained how it could work by saying, "The VHST's 'tubecraft' ride on, and are driven by, electromagnetic waves much as a surfboard rides the ocean's wave. The EM waves are generated by pulsed, or by oscillating, currents in electrical conductors that form the roadbed structure in the evacuated tube way. Opposing magnetic fields in the vehicle are generated means of a loop superconducting cable carrying on the order of a million amperes of current."
He says the VHST would be highly efficient. Unlike a plane, "it does not have to squander unrecoverable energy climbing to high altitudes."
The VHST would accelerate to its maximum speed, then coast for a short while, then decelerate, says Salter. It would use all its kinetic energy to accelerate, and that power would be returned when it decelerates through energy regeneration.
In 1972, the Rand Corporation said it had already examined speeds of 14,000 miles per hour. At that speed, it would take 21 minutes to go from Los Angeles to New York City.
According to Salter's research, a coast to coast VHST trip would happen faster than it takes a plane going coast to coast to get to its peak altitude.
The VHST would have to be underground. Digging the tunnels would be the biggest problem with creating the VHST. It would require political agreement and high costs to dig the actual tunnels. (90% of the cost would be building tunnels.)
There are a lot of benefits to a tunnel, though: "protection against sabotage, right of way costs, surface congestion, grade separation problems, and noise pollution go away."
Why don't we have the VHST?
Salter blamed political issues. He wrote, "History has shown that some obvious
projects, such as tunneling under the English Channel proposed in the time of Napoleon, can be delayed for centuries because of political pressures."
However, he did a crude break down of the economics and he believed that a VHST could be a profitable operation. It would make money by transporting ~106 million people per year. It could also do transportation of goods to generate additional revenue.
The high velocity at which the tubes move is equal to 1G of force at top speed, which is similar to the force felt by someone traveling in a car on the freeway.
i'd be damned if all the US airlines allow this. hell gulfstream would be out of business within minutes!
