    I want my Hyperlube transport now; EVs are so 2008 ;)

    I thought it was hyperloop. Either way, sounds intriguing.

    Hyperloop. Me thinks vacuum travel.

    I've always thought the vacuum mail tubes would be fun? to ride in.
    how about a tube that was an electromagnetic coil, solar powered with a magnetic train. just sayin

    He also said storing energy overnight. So a pressurized tube makes more sense to me. You'd need some kind of "airlock" system at the stations.

    Exactly! Kind of reminds me of one scene from Polar Express.

    If done at the right scale (not too big as costs would soar) to accommodate cars/trains of moderate size like 12 to 20 passengers at a time I could see this being a much safer form of mass transit.

    Even a 1/4 of the proposed max speed of 4K MPH would be much faster than the other 4 forms of transport.

    Considering natural disasters you could design the system to gracefully shut down very quickly. And allow for several feet of give when crossing tectonic faults.

    It would be very interesting to see this attempted over a stretch of 10 or 20 miles with a smaller vehicle to prove it's viability. Isn't there a worlds fair coming up?

    Regarding tubes... He said something like "not exactly, but you're on the right track" when she mentioned the Jetsons. It didn't hit me 'til this morning. He might have meant close in the sense that she should have said Futurama.

    Thanks for sharing the link, watched this the other day, and noticed Elon has now tweeted about the hyper loops.. I wonder how serious he is about this :wink:

    "Not a vac tunnel btw".

    It was an interesting interview, and I agree with what others have said that is interesting to just watch him talk and see how his brain is working :)

    Open source.. Guess he doesn't have time to go after it himself and doesn't want to see it delayed.

    If everything he says about the Hyperloop is accurate, maybe they'll do that instead of the new high speed rail in California.

    This Hyperloop thing kept me thinking. I don't know if this is a good idea, but at least it's an idea. ;) Somewhat based on Elon's description of high altitude jets / fans operating at low air pressure:

    So not a vacuum tunnel, but a somewhat air-tight tunnel for the pods (or ideally plexiglas tube above ground or below water in the Pacific, or whatever). One for each direction of course. And two air pipes along them, one with high air pressure, one with low pressure / vacuum, and every 100 ft or so, remotely controlled valves that connect the pipes with the tunnel. Then, when a pod is traveling in the tunnel, the valves for the low-pressure/vacuum pipe open ahead of the pod, and the high pressure valves open behind the pod. So the pod itself has no motor or anything, but is driven by the high pressure behind it, and the low pressure in front of it (which also decreases the aerodynamic resistance). Probably won't work because it's too inefficient (or impossible) to create a large enough pressure difference in the tunnel, but maybe it was an entertaining thought...

    Or is that actually how the office pressure communication works...? :)

    This would be a nice automated and safe transportation...

    @Steph - I'd love to see "BattleBots 3D cage" as a next step in such research.

    That was my take on the "Hyperloop" ;)

    What if you make this thing big enough to carry a car from point A to point B on short haul?

    4 Tesla motors, a skateboard, some software to control and navigate, small landing and takeoff areas. With the 85kw battery, this thing could fly for a few hours probably (didn't do the maths, I feel lazy) That could be a flying taxi fixing all traffic problems Elon hates so much (I feel the same as he and when I saw this thing a while ago, I though it could be a revolution ;)

    Hey! And the solar panels above could pressurize the pipes even when no capsules are running. And at night the pressurized pipes can still power (blow?) the capsules forward because they are (over-)pressurized. (As Elon hinted.)

    Regenerative breaking can be achieved by pumping air from in front of the capsule back into the pipes.

    What kind of diameter are we talking about?
