NORTH LAS VEGAS, Nev. (Reuters) - A
car-sized sled powered by electromagnets rocketed to more than 100 miles
(160 kph) an hour through the Nevada desert on Wednesday in what the Los
Angeles company developing the technology said was the first successful
test of a futurist transit system called hyperloop.

Hyperloop One is among several companies competing to bring to
life a technical vision by Elon Musk, the founder of rocket maker
SpaceX and electric car company Tesla Motors, who suggested sending
pods holding passengers and cargo inside giant vacuum tubes between
Los Angeles and San Francisco.
It's a matter of debate how soon – or whether – passengers and cargo
will ride the system at velocities approaching 750 miles per hour
(1,200 kph), but Hyperloop One already has raised $80 million from
backers including clean technology venture capitalist Khosla
Ventures; high-speed railway SNCF, the French National Rail Company;
and GE Ventures.
Brogan BamBrogan, a former SpaceX engineer who co-founded Hyperloop
One, called the test a major milestone.
 "Technology development testing can be a tricky beast," he said to a
crowd of 300. "You never know on a given day if things are going to
work exactly like you want."
The sled began on a train track and then was rocketed to 105 miles
per hour by electromagnets as electricity was shot into copper
coils. After a short ride, the sled ran into a sand trap, sending
out silicon sprays. If all goes according to plan, sleds will
levitate and carry pods in a test later this year. Gigantic tubes
already are scattered around the Las Vegas area test site.
Company Chief Executive Rob Lloyd on Wednesday forecast a hyperloop
would transport cargo by 2019 and passengers by 2021.
"We're practicing large, fast construction that includes robotic
welding. Techniques that allow us to create a perfect production
level," he said. "What people think takes years should take
quarters."
Musk created a stir by saying California could build a hyperloop
from San Francisco to Los Angeles for around $6 billion, a 10th of
the cost of the state's high-speed rail project.

Skeptics say real-world challenges ranging from construction permits
to making the new technology work mean the costs are likely to be
far greater.
"The hyperloop might be promising, but it's still unproven and just
an idea. High-speed rail is a proven technology that's been in use
around the world for decades," said Lisa Marie Alley, a spokeswoman
with the California High Speed Rail Authority.
A hyperloop, she said, will run into the same challenges of any
other large infrastructure project, including funding, right of way,
environmental permits, approvals and clearances. "None of it is
easy," she said.
Alon Levy, a mathematician who writes about mass transit for the
blog Pedestrian Observations, said the cost estimates from hyperloop
backers do not fully take into account difficulties such as
engineering turns at jet speed or even digging tunnels.
"I do think Hyperloop can be built. But making it work requires much
more money than the builders think, and much more than conventional
high-speed rail," he said.
