Well I'll be darn, this thing may wind up getting built!
Will certainly cost a fortune. So far, the company is being crowdfunded. Maybe if it gets off the ground, state govs and municipalities and federal gov could pay for sections, to complete the hyperloop.
Article says the hyperloop pods will be made of "inconel," an alloy used by Spacex.

A new firm, Hyperloop Transportation Technologies, is developing plans to makes the tubes a reality - and it has recruited experts from around the world.
The crowdsourced firm has around 100 engineers on the projects, and nearly all of them have day jobs at companies like Boeing, NASA, Yahoo!, Airbus, SpaceX, and Salesforce.
Dirk Ahlborn, the CEO of the new company, says it seemed the perfect way to develop the plans, with a site called JumpStartFund that aimed to crowdsource ideas.
He got in touch with SpaceX, Musk's firm, and the work began.
The team includes about 25 UCLA graduate architecture students at a facility in Playa Vista, although most members work remotely.
Ahlborn hopes to have a technical feasibility study finished in mid-2015, according to Wired.
So far, the team has made progress in three main areas: the capsules, the stations, and the route.
Inside the tubes, hyperloop pods are mounted on thin skis made out of inconel,an alloy already used by Musk's SpaceX firm that can withstand high pressure and heat.
Air is pumped into the skis via small holes to make an air cushion, and each pod has air inlets at the front.
An electric turbo compressor compresses air from the nose and routes it to the skis and to the cabin.
Magnets on the skis, plus an electromagnetic pulse give the pod its initial thrust; reboosting motors along the route would keep the pod moving at just below the speed of sound so the system does not produce sonic booms.
