Elon Musk plans to build Hyperloop test track
The CEO of SpaceX and Tesla wants to speed up the development of 800-mph
tube transport. He's willing to pay for testing -- most likely in Texas --
to make it happen.
Billionaire and entrepreneur Elon Musk is getting more hands-on with the
Hyperloop.
Musk, who heads up both space transportation outfit SpaceX and electric-
vehicle maker Tesla Motors, casually announced via Twitter on Thursday that
he's decided to help accelerate development of his vision for near-
supersonic tube transportation, first outlined in August 2013.
Musk said he will build a five-mile test track for the still-theoretical
system for students and companies to use. A possible location would be Texas
, he added, where presumably there is plenty of flat land to go around.
Though Musk speaks of the Hyperloop with similar nonchalance, the idea could
revolutionize land transportation. It's simpler than it sounds. A Hyperloop
would work similarly to an air hockey table, but instead of floating on a
cushion of air, solar-powered electromagnetic pulses would propel
pressurized cabins inside elevated tubes.
Theoretically, the resulting system could reach speeds approaching 800 mph,
faster than the speed of sound, through tubes held up by pylons placed
between strategic cities like San Francisco and Los Angeles. The system
still needs years of testing, and as much as $10 billion to create even just
one 400-mile stretch.
Yet Musk's willingness to get involved after almost a year and a half of
silence on the subject shows he's serious about the idea and will, as he has
with his other ventures, spend some of his own money to get it off the
ground.
Critics, including members of the US High Speed Rail Association, say high-
speed rail is a more-viable option. High-speed rail is widely used
throughout Asia, and the state of California this month broke ground for its
high-speed rail system costing $70 billion. Musk has criticized the project
's high costs and sees the Hyperloop as leapfrogging the technology.
Musk isn't alone in trying to make the idea a reality. A group of
entrepreneurs and scientists have banded together to create Hyperloop
Transportation Technologies. Put together first on a crowdfunding platform
called JumpStartFund, it's a collective of around 100 engineers,
unaffiliated with Musk, who exchange free time for potential equity. Each
works in small teams focused on specific interests, such as designing
passenger pods and propulsion prototypes.
Hyperloop Transportation Technologies has also partnered with UCLA's
SupraStudio design and architecture program to design capsules and stations,
as well as work out prospective routes around the country that could
potentially be linked into a nationwide Hyperloop network.

The Hyperloop concept is proposed to operate by sending specially designed "
capsules" or "pods" through a continuous steel tube maintained at a partial
vacuum. Each capsule floats on a 0.5-to-1.3-millimetre (0.02 to 0.05 in)
layer of air provided under pressure to air-bearing "skis", similar to how
pucks are suspended in an air hockey table, thus avoiding the use of maglev
while still allowing for speeds which wheels cannot sustain. Linear
induction motors located along the tube would accelerate and decelerate the
capsule to the appropriate speed for each section of the tube route. With
rolling resistance eliminated and air resistance greatly reduced, the
capsules are theorized to be able to glide for the bulk of the journey. In
the Hyperloop concept, an electrically driven inlet fan and air compressor
would be placed at the nose of the capsule in order to "actively transfer
high pressure air from the front to the rear of the vessel," resolving the
problem of high speed transport in a tube that is not a hard vacuum, wherein
pressure builds up in front of the vehicle, slowing it down. A fraction of
the air is shunted to the skis for additional air pressure, augmenting that
gained passively from lift due to their shape.

拼人工的制造业和基建都会被中国人做绝，中国工人太多太强了。本来西方也很强，但
给力薄肉搞几十年素质下降厉害，而且人数比不过。
这个hyperloop被商业化以后，tg照样白菜。

没必要全真空，而且气垫还需要车头进气来操作，减压是肯定的。
