The solar-powered system, which Musk previously described as a cross between a Concorde, rail gun and air-hockey table, would shoot as many as 28 passengers in each enclosed capsule through a low-pressure steel tube at up to 800 miles per hour, according to the 57-page design plan.
The plans are also open-source, meaning anyone can build upon and improve them. I suppose it’s too much to hope for that this could be the start of a cross-country high-speed rail system for the U.S., what with the lobbying dollars that the airline industry likely has, but it’s nice to dream.
