It's a race befitting the goal of moving passengers and cargo at the speed of sound: Three Southern California companies are building separate test tracks to see how well the "hyperloop" transportation concept works in the real world.
Billionaire entrepreneur Elon Musk breathed life into the hyperloop in 2013, when he proposed a network of elevated tubes to transport specially designed capsules over long distances. Top speed: about 750 mph.
Though momentum to build a hyperloop has been growing since, the concept dates back decades.
Capsules would float on a thin cushion of air and use magnetic attraction[sic] and solar power to zoom through nearly airless tubes. With little wind resistance, they could make the 400-mile trip between Los Angeles and San Francisco in about a half-hour. Musk has said that while he does not plan to develop the hyperloop commercially, he wants to accelerate its development.
On Tuesday, his SpaceX rocket launching firm said global infrastructure firm AECOM would build a one-mile track at SpaceX headquarters near Los Angeles International Airport.
If all goes well, by summer's end, the track will host prototype capsules that emerge from a design competition this weekend at Texas A&M University. The prototype pods would be half the size of the system that Musk envisioned and would not carry people.

a relatively small environmental footprint...... The steel tubes ... are set on 20-foot concrete pylons placed every 100 feet. This elevated configuration avoids the environmental disruption involved with underground construction.
Depends on what you mean by "envirionmental disruption". If you only ever walk around looking at your feet (as introspective geeks are reputed to do), you will only notice the hyperloop if you bump into a pylon. However, if you look up sometimes, these things will be eysores of the first order.
avoids the environmental disruption involved with underground construction
Eh ?? Must have taken a lot of nerve to spin that somersault. In the UK here, underground tunnelling is used as a way of minimising disruption, not just constructional, but environmental and all other forms of it as well. The only disruption is around constructional access points which can be miles apart, and such tunnelling is now routine. OTOH, constructing an overground hyperloop, with a pylon every 100 ft, is going to be a lot of disruption during construction.
