After a slew of hints, billionaire and founder of Tesla Motors has finally revealed the plans for Hyperloop, a high-speed rail service that aims to passengers from San Francisco to Los Angeles in a little under half an hour—faster than an aircraft.

Musk revealed final details for the open source project in a blog post. The PDF documenting the plan is a whopping 57 pages, going into intricate detail about exactly what the Hyperloop could provide. According to the plan, the Hyperloop will enable passengers to travel at 800 miles per hour in aluminum pods. A passenger only system would cost $6 billion to create, versus $10 billion for a larger model that could transport vehicles. The Hyperloop would be able to maintain high speeds without losing friction by keeping the interior of the Hyperloop with low pressure.

Hyperloop consists of a low pressure tube with capsules that are transported at both low and high speeds throughout the length of the tube. The capsules are supported on a cushion of air, featuring pressurized air and aerodynamic lift,” he writes in the plan. “The capsules are accelerated via a magnetic linear accelerator affixed at various stations on the low pressure tube with rotors contained in each capsule. Passengers may enter and exit Hyperloop at stations located either at the ends of the tube, or branches along the tube length.”

The Hyperloop would be constructed along much of California’s I-95 on elevated tubes on columns 50 to 100 yards apart. The vessel could also be built with solar panels, allowing it to generate electricity. Each capsule would hold 28 passengers and depart every thirty seconds during peak times. Musk estimates that the capsule should cost just $20 per each one-way ticket.

Musk’s Hyperloop is the answer to California’s “High-Speed Rail” system, which he finds to be poorly planned.

When the California ‘high speed”’rail was approved, I was quite disappointed, as I know many others were too,” he wrote on his blog post. “How could it be that the home of Silicon Valley and JPL – doing incredible things like indexing all the world’s knowledge and putting rovers on Mars – would build a bullet train that is both one of the most expensive per mile and one of the slowest in the world?”

California bullet train would cost nearly $70 billion to create and would charge passengers $105 per one way ticket with a travel time of just over two and a half hours.

Because he’s busy focusing on other things, he’s decided to release the plans as an open source. “I did commit to publishing a design and provide quite a detailed design [but] I don’t have any plan to execute because I must remain focused on SpaceX and Tesla,” he said. “If nothing happens for a few years, with that I mean maybe it could make sense to make the halfway path with Tesla involvement, but what I would say is you shouldn’t be speculative.”

And that’s not the only project he’d take into his own hands if it isn’t executed within the next few years. Musk also briefly mentioned his interest in a supersonic jet that would have vertical landing, much faster ascending and descending times, low sonic boom, and would transport passengers at a much faster rate on a much smaller scale than a traditional aircraft.

As for Hyperloop, Musk is actively seeking feedback and ideas on improvements, and may consider building a prototype. He believes a prototype designed by someone else would take three to four years to complete, while if Hyperloop was his main priority, it could take one to two years.
