Hyperloop One completed the first full-scale test of its hyperloop technology in a vacuum environment on May 12th, the company announced today. In the test, the company's hyperloop vehicle - which uses magnetic levitation, or mag-lev, technology - pulled 2 Gs while reaching 70 miles per hour down the length of the company's test track in Nevada.

The company is now entering the next phase of testing with the goal of reaching 250 mph. A concept first conceived by Elon Musk in 2013, the hyperloop theoretically can send aluminum pods filled with passengers or cargo through a nearly airless tube at speeds of up to 750 mph.

"Hyperloop One has accomplished what no one has done before by successfully testing the first full scale Hyperloop system," Pishevar said in a statement. "By achieving full vacuum, we essentially invented our own sky in a tube, as if you're flying at 200,000 feet in the air."

In October, Hyperloop One began construction of its 500-meter-long "DevLoop" test track, which became operational last April. The company says it will continue to run tests at DevLoop in the coming months to "validate its next-generation components and software." The next phase of testing will showcase the Pod gliding along a longer track at faster speeds. To be sure, the hyperloop has a host of challenges to overcome before it can claim to revolutionize transportation. It's very difficult to build anything new in the US, especially something as huge and enormously expensive as the hyperloop. This is an entirely new technology, built from scratch without any of the right-of-way allowances, land acquisitions, or regulatory approvals that other modes of transportation, like the railway, currently enjoy. Suffice, it will be many years before you are able to sit back and let the hyperloop whisk you away to your destination at its promised speeds.

While the approval is merely verbal at this point, this could be a genuine step toward the Hyperloop becoming reality: the plan is to build an underground Hyperloop between New York and Washington, which would also stop at Philadelphia and Baltimore. One could get from New York to DC in just 29 minutes.

Awesome stuff.

If anyone's interested the white paper is very interesting if while slightly different from Hyperloops approach.

PR stunt? Last I checked, no state or federal officials have approved this.
This guy is the King of PR stunts and corporate welfare. He built an empire with a powerpoint deck ffs!

How the hell are you going to build a loop into the city center? Does he plan to dig under the existing sewer system, train system, and piping from outside the city and in? Retrofitting for a city that is already established sounds expensive.

decent price with a 10 year warranty on the engine and battery, which is more than be said for other cars who have moved to mostly 5 year warranties.

not to mention no gas, and if you live in an area with public charging stations, free electricity... not to mention tax credit for buying it...

Cool.

To the non-engineer this may look underwhelming, but it really isn't*. Once you've proved the concept is valid and works on a full scale model, the rest is reasonably easy. That's not to say there won't be challenges, the 250mph test will be interesting for sure, but it is a big step forwards.

If developed fully, this system could be a great replacement for many short haul domestic flights. This is important as there are no readily available alternatives to fossil fuels for powering aircraft. If we can reduce the number of flights in favour of something that can be powered with electricity (and concurrently produce more electricity through renewable means) it will help.

I work on sites all round the world, so I usually have an interpreter with me. Once, when starting up a particularly large piece of equipment, the interpreter asked me how she'd know if it went well.

I replied with "if it goes well, it'll look like nothing happened and I'll be standing here looking satisfied".

"What if it doesn't go well?"

"I won't be standing here. I'll be over there and still accelerating. Try to keep up."

We started the equipment up, and it went well. The interpreter looked fairly disappointed at the lack of any outward signs of anything happening. Since this was a 1,050kW fan, I'm glad she was disappointed.

This is actually an astounding achievement and as someone who studied engineering even briefly I can recognize it.

The issues going down the road lie within the political and social sphere. Good luck getting permits from multiple states to start a project like this. Really, I wish them all the best I mean that, but as a resident living just north of NYC the odds of this actually being constructed here are pretty close to zero.

There is a lot of red tape involved with creating this kind of system that could cross the country, so much that its not even worth delving into the entire list.

This.

Just another PR stunt to get Washington to open the purse strings...

I like Elon's ideas but am getting tired of paying for his excursions... Government handouts need to stop for all entities... We are inching towards $20 Trillion in national debt and there is no end in sight to spending...

How do you figure?

THey are performing this inside a vacuum which removes wind resistance.

Thats a pretty big deal.

For starters... It reached a wopping 70 mph... They are hoping for speeds up to 250 mph in the future with a potential cap at 750 mph. Maglevs can already do over 250 mph and have been recorded speeds up to 400 mph.

The fact that you need to vaccum seal a track chamber is the only real addition to traditional maglev trains. Having hundreds of miles of vaccum track isn't exactly a cost effective endevour...

Maybe instead of hating on Elon you need to instead start hating on the Pentagon...

https://www.reuters.com/article/us-usa-afghanistan-military-idUSKBN1A92PH?il=0

if someone can please tell me why our taxpayer money is buying afghanistan uniforms that cost 28 million dollars... thanks... how about we buy them tan shirts from walamart and tan pants too, and save the taxpayer 27 million dollars... at least the color would have been right... sigh. our own people cant even afford medicine and we just give away crap ton of money all the time. it annoys me.

I am against all frivolous spending by Washington. I was against the spending in California so I left the state and no longer directly contribute to their coffers. I am still indirectly supporting California through my Federal tax bill...

Also, you are complaning about 28 million when the military has a budget of over $500 billion and there are plans to increase the budget by 10%...

Current Maglev trains operate in atmosphere, so their speed is limited by the amount of power they can output. Aerodynamic drag increases proportional to the square of the velocity1, so you very quickly reach the limit of speed. Additionally a train operating in atmosphere has to continuously use power to maintain speed.

By operating in near vacuum, you dramatically reduce this problem. The plans for the Hyperloop have the sled being accelerated at the station, and then boosted at various points down the line. By reducing the pressure in which it has to operate there is really no major difficulty in achieving much higher speeds. 750mph is not unfeasible.

Cost is an interesting issue - since it is a lot lighter than railways and can be supported on pylons above or alongside existing freeways (vastly reducing the cost involved in purchasing land) it may actually be cheaper to produce than a new train track.

1 FD=1/2 ρ v2 Cd A

Where

FD is force due to drag

ρ is fluid (atmospheric) density

v is velocity

Cd is the drag coefficient (property of the body)

A is the frontal area of the body

It will be a pain in the arse to achieve these building warrants but im sure it will get done. Sucks to be the Engineers in charge of this. However, if it's done right, this could lead to a new standard for the country.

Biggest pain I could see in this process would be implementing the correct safety in the event of emergencies. What happens if there is a fire on the train in a vacuum tube? How does one evacuate in case of a breakdown or crash? So on and so forth. To my knowledge, there is not an existing standard to maintain safety. They could possibly apply a lot of regulations and standards from train transportation but I doubt most would be applicable.

Yeah if you think this is underwhelming I guess you dont know the real potential of these kinds of systems, or their variants. This system can be used to launch objects into space, and there are quite a few other variants to it that can be used either for lightning fast transportation or for other means like the aforementioned "space train". These things could go faster than planes, be cheaper, and be easier to maintain and have MUCH higher safety margins.

But again this is never going to happen on a grand scale in this country in my opinion, for so many reasons. The main one being as I said attaining the ability and rights to construct such a gigantic system underground in areas where there is already tons of underground infrastructure.

And whoever said NY is a dump you, quite frankly, don't know what you're talking about.

Good luck digging 6km below the surface. This will either have to go at something like 200-300m underwater, OR go on the sea bottom/below it. 2 issues with both - 1st, you will get affected by currents, non-stop sideways movement + stretching/contracting. 2nd will be the pressure, plus you will have vacuum on the inside.
