Enthusiasts behind Elon Musk's "hyperloop" proposal (an intercity tube that speeds passengers riding in capsules at 600 miles per hour) have taken the next step, producing a report outlying some of the big issues around the project.
Hyperloop Transportation Technologies' 76-page report focuses issues surrounding a system that could connect San Francisco with Los Angeles.
The report says, however, that there are many city pairs around the world that would be candidates for a hyperloop.
The 400-plus-mile trip would take less than an hour, compared to more than six hours of driving.
The goal is to keep the ticket price in the $20 to $30 range, although the report points out that at total cost estimates of $16 billion, they could go higher. Still, it says, hyperloop would be a bargain compared to alternatives.
