    Train could go from LA to NY in 45 minutes if new vacuum tube technology is developed

    The serial entrepreneur envisions a future where mag-lev trains in enormous pneumatic tubes whisk us from Los Angeles to New York in 45 minutes.
    A massive vacuum tube mounted either above ground or even under water would be combined with a magnetic levitation system used on conventional bullet trains. That means no friction, no wind resistance, no chance of collisions, and insanely high speeds.
    Musk described the Hyperloop as "a cross between a Concorde, a railgun and an air hockey table," at AllThingsD's D11 conference earlier this year. And in an interview with PandoDaily, Musk said the Hyperloop could form a fifth tent pole of modern transportation, joining cars, planes, trains, and boats, adding that because of its low energy usage and ability to get juice from solar power, it could generate more power than it would consume.

    I'd give it a shot. But accelerating and slowing would be hard on you.

    I don't see it happening. A vacuum tube? Takes one asshole putting a hole in it to kill everyone aboard. Losing vacuum with a train going 4000mph would be catastrophic

    The idea's been around for quite a while. I don't remember if it was Robert Heinlein or someone else that featured them... Though I think Heinlein's thing was suborbital rockets for rapid transit.

    It'd need significant safety protocols, but energy wise, could be surprisingly inexpensive, because gravity would help generate speed, then slow you down. Acceleration/deceleration effects on the body would also have to be covered. Might require a physical exam to ensure sufficient health to survive the trip.

    Oh, wait. Doesn't TSA already give you a physical exam and free x-ray with every trip?
