>> Three, two, one.>> A technology who's backers are promising to disrupt transportation as we know it, getting a confidence boost in the Nevada desert Wednesday.>> I'm Reuters correspondent Rory Carroll in North Las Vegas, where Hyperloop One has successfully completed a test of the propulsion system for the Hyperloop.
The system aims to transport people and cargo in levitating pods through vacuum tubes at a pace approaching the speed of sound around 750 miles an hour. The idea came from Elon Musk, but with his hands tied running SpaceX and Tesla Others have run with it, with Musk's blessing.
In Wednesday's test, Hyperloop One, one of the few companies vying to make the technology a reality, shot a sled along a short track at over 100 miles an hour. Execs say the technology would trim the 400 mile trip between Los Angeles and San Francisco to just half an hour.
With estimates of costs around $6 billion.>> The skeptics argue that the Hyperloop is an unproven, untested technology many years away with expenses that are unknown at this point and that conventional means, like high speed rail are better suited to transport goods and cargo and people through the US.
>> Hyperloop One has a long way to complete even one leg of the network. It's raised just $80 million in new funding but expects to have a fully working system by 2020.>> But it's easier than building a spaceship.
