Elon Musk's proposed Hyperloop

Elon Musk is proposing a hyperloop for boats, planes, automobiles, and trains. He states he can deliver a system of train transport from LA to SF in 30 minutes (343 miles) at 685 MPH. He claims this can be done for 6 billion or one tenth of the proposed cost of the high speed rail being considered.

Is this possible .... would you ride this? He says facts will be made available in August 2013.

What do you think of this proposal? Should he be considered for a TED Talk? Would you watch it?

    If its initial speed were zero and it took 2 minutes to reach 686 MPH, then we can assume it would take that amount of time to slow down, adding 4 minutes. to the 30 minutes or 34 minutes for the trip. It's average speed would only be around 605 MPH. I'd need more information to answer the question Robert.

      Thanks for the reply.
