US-based entrepreneur Elon Musk has revealed details of a supersonic "Hyperloop" transportation system linking Los Angeles and San Francisco.
The SpaceX, Tesla and Paypal founder envisions using magnets to shoot capsules supported by a cushion of air through a miles-long low-pressure tube.
A Hyperloop between San Francisco and Los Angeles would cost $6bn (£2.7bn), he estimated.
But Mr Musk says he is currently too busy to develop the project himself.
Only if no-one else picks up the challenge will he consider attempting to realise the concept in the future.
In an interview and in a paper outlining the Hyperloop proposal, Mr Musk has suggested the system would be a faster, less costly and more efficient mode of transport between Los Angeles and San Francisco than the high-speed train currently under development.
"I originally started thinking about [Hyperloop] when I read about California's high-speed rail project which was somewhat disappointing," he told a Google Hangout with Richard Branson last week.
"It's actually worse than taking the plane. I get a little sad when things are not getting better in the future.
