elon musk hyperloop

On Monday, Musk published his design for a futuristic transport system called the Hyperloop (above), which he says could be three or four times faster than a bullet train and immune to crashes and bad weather.

But don't expect him to drop everything for the new project. Musk told analysts last week that he will "invite critical feedback and see if people can find ways to improve" his Hyperloop design, adding that he has no immediate plans to develop the project.

"I have to focus on core Tesla business and SpaceX business, and that's more than enough," he said.
