Elon Musk, founder of PayPal, Tesla Motors and SpaceX, has released the alpha version of Hyperloop, a proposal for a high-speed train connecting Los Angeles-San Francisco. The Hyperloop would cover the proposed 570 km route in around 35 minutes, at an average speed of 962 km/h. The Hyperloop document can be downloaded here.
Technical details aside, the first pages of the document offer a good insight on how Musk frames a problem and compares alternatives.
