Comments on Hyperloop Transport Proposed By Tesla's Elon Musk
'...an hollow tube must be constructed the whole distance... of such dimensions as to admit a four wheeled carriage...'- George Medhurst, 1812. (Read the complete story)

"The Musk 'Hyperloop' transportation system sounds similar in some ways to the ET3 Evacuated Tube Transport system also under development. Take a look at this cool concept drawing, which will probably be similar to the Musk Hyperloop system (from the outside, anyway). (ET3 Evacuated Tube Transport) " (Bill Christensen 7/13/2013 4:35:14 PM)

"How cool is Elon Musk, anyway? I mean, he founds a company and a team that develops and manufactures the highest rated car ever reviewed by Motor Trend (see Tesla Model S Declared Car Of The Year By Motor Trend). Awesome. And now, he's working on an even more advanced transportation technology that could at least partially alleviate the need for private car ownership!" (Bill Christensen 7/13/2013 4:46:34 PM)

"I absolutely agree! And of course, don't forget SpaceX making private space travel possible! He's like a modern day Edison but with advanced transportation" ( 7/13/2013 7:02:31 PM)

"I would think this would also give a huge boost with tourist dollars to the economy with everyone being able to travel to and from in a single day all over the US." ( 7/13/2013 7:23:21 PM)

"Take a look at a few of Musk's projects, and their science fiction antecedents - a modern-day Edison, indeed.: Private Space Flight At 'Inflection Point' Science fiction fans have long been comfortable with the private exploration of space. Tesla Model S Not Your Grandfather's Electric Phaeton John Jacob Astor IV set forth a marvelous vision of a national fleet of electric phaetons that would truly revolutionize motor transport in his 1894 story A Journey in Other Worlds. Space Junkyard in North Hollywood Robert Heinlein looks for a ship in a whole field full of freighters abandoned on the Moon in his 1941 novel Methuselah's Children. SpaceX Dragon To Land On Any Planet I thought I'd mention that this private space craft that can easily take off and then land back on a planetary surface sounds a lot like science fictional space craft like Heinein's Joy-boat Junior. SpaceX Grasshopper Rocket Lands On Its Tail For decades, sf fans have dreamed of having rocket ships that can land on their tails, like sf writers intended. " (Bill Christensen 7/13/2013 9:21:19 PM)

"I did some rough calculations and his hyperloop could actually provide excess power via solar panels. Several hundred miles of Photovoltaics will generate a LOT of juice and the proven battery packs of the Tesla will work well for nights and cloudy days." (Dewtey 7/16/2013 5:36:30 AM)

"That's amazing, I didn't think about that. He's going to be describing the details this week - we'll soon see how accurate you were in your rough calculations. Which you should share, btw. I was thinking about it more in terms of the magic of truly frictionless travel. If there is no friction in wheels and such surfaces, and no friction from that pesky atmosphere of ours, you could actually give a capsule a good shove, and it would travel all the way across the country. Not fast, of course, and not up hills. But still, that's all you'd need in terms of energy to send it on its way." (Bill Christensen 7/16/2013 11:05:38 AM)

"Figure 90 watts per square meter, 4 meters wide, 630000(630KM) meters LA to SF. comes out to about 225MW. And that's only if the tubes are stacked like the ET3 configuration. Double it if the tubes are side by side. Backup battery packs every KM or so. The Realized energy per Sq/M might be even higher than my low ball estimate." (Dewtey 7/19/2013 4:15:26 AM)

"Lest we not forget, the Falcon 9 is 3.6 meters in diameter and fairly strong. So Mr. Musk even has the manufacturing ability to make the tubes." (Dewtey 7/19/2013 5:02:26 AM)

"Your calculations seem reasonable. You're whetting my apetite for Musk's August 12 press conference. I've just found another source that claims that Musk has already stated that the system does not use an evacuated tunnel design. Here's Musk with Falcon 9. (Elon Musk standing with Falcon 9's Merlin-IC engines) " (Bill Christensen 7/19/2013 5:05:59 AM)

"See these articles for expert speculations on the Hyperloop. If I have time, I might create another article. See How Elon Musk’s Hyperloop might actually work and Elon Musk’s Hyperloop transport system not a vacuum tunnel, here’s all we know." (Bill 7/19/2013 5:19:06 AM)
