The " Hyperloop , " a suppositious high - speed transportation system that could shuttle citizenry between Los Angeles and San Francisco in only 30 minute , just speed up a bit closer to reality .
First proposed in 2013 by billionaire entrepreneurElon Musk , CEO of Tesla Motors andSpaceX , theHyperloopwould transport passengers in float pods inside humiliated - insistence tubes at speeds of more than 750 miles per hour ( 1,200 klick / total heat ) .

Now , the company Hyperloop Transportation Technologies Inc. ( which is not affiliate with Musk or Tesla ) has inked a deal with landowners in fundamental California to build the humankind ’s first Hyperloop trial track , accord to market research firmNavigant Research .

Separately , Musk has said he plans to build his own 5 - mile test track , likely in Texas , for society and studentsto test out likely Hyperloop designs .
How Hyperloop will work
Musk lay out his plans for the Hyperloop in apaper release on the SpaceX internet site . He has discover the superspeedy mode of transport as a " cross between a Concorde , a rail throttle and an air - ice hockey mesa . "
The thought is , passenger pods will move inside thermionic valve under a fond vacuum , and will beaccelerated to blistering upper using attractor . A set of fans tie to the pod will permit the train to lie on a cushion of gentle wind . The system would be power by solar dialog box along the duration of the tube .
The world’sfastest magnetically levitated ( magnetic levitation ) traintravels at about 310 mph ( 500 km / h ) . Maglev train work by using magnets to produce both lift and propulsion . By dividing line , the hyperloop would only practice magnets for actuation , rely on tight air travel for airlift . Maglev trains are in operation in Shanghai and Tokyo , and South Korea plan to open one in June .
Hyperloop pods could theoretically travel very fast , because they would n’t have to sweep over rubbing between the cycle and track that a typical train United States , or the gentle wind resistance that conventional vehicles experience at eminent speeds .
" you’re able to go a couple of hundred miles an hour with a wheel , as the French and Germans and Japanese have proven , " said Marc Thompson , an engineering advisor at Thompson Consulting Inc. in Boston , who has make for on maglev systems . But , " as you go faster , the drag violence on the string becomes a very high energy cost . "
The design Musk purport would travel at speeds of up to about 760 mph ( 1,220 km / h ) , but the test project , which aims to recrudesce primer in former 2016 , would be screen at 200 mph ( 322 km / h ) to prove it works and is dependable , Navigant reported .
At that speed , the gentle wind drag is still possible to get the better of , but beyond that , the power needed to transcend the pull increases as the speed dice , enjoin James Powell , a retired physicist and co - artificer of the superconducting magnetic levitation concept .
Is it feasible ?
The Hyperloop has the potential drop to be afaster , chinchy and more energy - efficientform of travel than planes , trains or bus , its proponents say . However , it ’s not yet make love if the technology is feasible , or safe . [ Video : What on Earth Is a Hyperloop ? ]
For one affair , the tubes have to be very straight , leaving very little way for error . " The guideway [ track ] has to be built to very fine tolerance , because if the military position of the paries deviates from straightness by a few thousandth of an column inch , you could break up , " Powell state Live Science .
The tubing also have to exert low - pressure atmosphere . " The job with traveling in an evacuated thermionic valve is , if you lose the vacuum in the tube , everybody in the tube will doss down , " Powell said . In addition , the fomite ’s compressor — which bring about the breeze cushion on which the pod rest — ca n’t fail , or the pods will break up into the bulwark , he append .
" The whole system is vulnerable to a single - point failure , " Powell say . For example , somebody could blow a hole in the tube ’s side , oran earthquake(no rareness in California ) could shift the tube by a fraction of an column inch , both of which would cause the vehicles to crash . In superconducting magnetic levitation , by contrast , the magnets are very stable and go reliably , Powell said . " It does n’t postulate uninterrupted control to keep it suspended . "
What will it be ?
But Powell questions whether the Hyperloopwould really be as cheap as promised . " The main cost of these high - focal ratio system is in the cost of the guideway , " he said . And because the path must be built so precisely , it ’s run to be more expensive , he added .
Even if the Hyperloop is successful , Powell does n’t think it will unsex the United States ' DoT problem — namely , congested highways and airways . " A few isolated high - amphetamine rail corridors in the United States really wo n’t direct our large trouble , " he said .
