Like a genuine, bona fide
Electrified, six-car hyperloop

What's it called?

That's right! Hyperloop!

I hear those things are awfully loud
It glides as softly as a cloud
Is there a chance the track could bend?

I take that as a serious insult to their modelling skills.  Seriously, give me some PVC pipe, some nice balsa, and a little paint, and this could be made very simply.  It's not a complicated form, at all.

He'll appear in pretty much any science thread to denounce it.  Amusingly if you call him on it he'll often use the line "but I'm sat in front of two oscilloscopes" which is cute; not that he knows how to work them, but some of the knobs click when he turns them.

Interestingly enough he doesn't seem to appear in genetics related threads; I suspect he doesn't believe DNA exists.

Like the majority of Musk's ideas it doesn't do anything new.  It basically welds together several items of mature technology in a slightly different way.   This has an advantage as far as 'HyperLoop' goes in that it's proven technology (kinda) but the fairly major downside that it's not 'backwards compatible' with any existing transit system.

I'm not sure that the backwards compatibility is really that much of a problem.  What are airplanes compatible with?  I do think that when the standard is developed (there DOES need to be a standard) it should be the "hyperloop plus" that can carry a couple of cars.  I do think that in a decade or two it will seem kind of quaint to take your car with you when you go to another city, but overall, the larger version will have a lot more flexibility.
 
2013-08-21 03:47:17 PM  

Hollie Maea: What are airplanes compatible with?


Well...

You can land an airplane on a boat.  Or, just land the plane on water, like a boat.  You can carry boats, cars, motorcycles, and other forms of ground transportation inside a plane, to reach areas that those vehicles otherwise couldn't access.

Kraftwerk Orange: You can land an airplane on a boat.  Or, just land the plane on water, like a boat.

That's true, but in the general transportation network, we don't.
You can carry boats, cars, motorcycles, and other forms of ground transportation inside a plane, to reach areas that those vehicles otherwise couldn't access.
Again, we could but we don't much.  If all of those capabilities were taken away, the airplane transportation system--as a system of passenger transport--wouldn't change much at all.  All of those other things are relegated to niches.  But again, the "Hyperloop Plus" could have the ability to carry those things in it.

Hollie Maea: I'm not sure that the backwards compatibility is really that much of a problem.  What are airplanes compatible with?


Airports usually.  Even the A380 doesn't require a brand new airport be built for it.  You can retrofit the terminals it needs on to existing systems.

Same applies here.  The trains used by his system can't run on regular rails and vice versa, you can't retrofit or upgrade existing rail lines to be a 'HyperLoop' compatible system.  That means everything has to be shiny new and no retrofitting can occur at any point.

It seems to be compatible with highways, though. The paper says that the poles holding the Hyperloop can mostly be put in the meridian of major highways, which will dramatically cut down on land costs.

I want to know what happens if you don't get enough momentum to go over the loop and get stuck in the low portion of the slide just before it. It seems like there would be no way to get out.

The Hyperloop will be awesome until the freight moving industry congests the tubes with freight traffic and the passenger pods are slowed to a crawl or stopped to give freight the right of way.
 
2013-08-22 06:41:12 AM  
And what happens if this 20+ft diameter vacuum tubing is breached?

All it takes is one terrorist with enough explosives to collapse the tunnel walls, and hyperloop is down for months of repair and cleaning.

Also have to deal with earthquakes and fault lines somehow.

The only thing interesting about the hyperloop is that, when completed, it will supposedly be low cost and energy neutral.

Otherwise, it is not a revolutionary new change in transportation.

We will still have to go through all the inconvenient hassles inherit in planes and trains, namely, security at the end-points, car rentals, and a limited number of destinations that never quite get us to exactly where we want to be.

If the idea is to rebuild the entire infrastructure from the ground up, look at the whole problem instead of just how fast you can get from LA to SF.
 
2013-08-22 09:04:20 AM  

Hollie Maea: Sheesh...you aren't even trying here.


No I'm not, I already explained it twice I can't be bothered with a third time and if you're too dumb to figure it out that's your problem not mine.

It can't be retro-fitted to existing infrastructure, it's not going to be built.  That's the end of it.
 
2013-08-22 09:15:48 AM  
To expand on that, what would the idea form of transportation be and how far is that from what we currently have?

1: Thinking yourself where you want to be
2: Teleportation booths
3: ???
4: ???
5: Current transportation.

Somewhere in that mix, I want to program a destination into my modular pod -- primarily used for local travel in the 500km range -- and, if I'm going to a place outside of local range, have it automatically take me to the rapid pod transport network and, without getting out of my pod, have its modular design allow it to connect to a larger and much faster vehicle that will take to a close approximation of where I want to be. Once at that close approximation, my modular pod will detach and automatically take me to my actual destination. While it is connected to the rapid transport mechanism, I'll be able to step out of my pod, stretch my legs, and maybe watch a short film or get a bite to eat.

Bonus points if it hovers and we can eliminate highways in favor of grassy lanes.

Shhh. Hollie still thinks you can buy up land rights to put in new infrastructure like power and rail and hyperloop lines. She doesn't understand that all that land was bought some half century ago, and contiguous plots of land for such project are extremely hard and expensive to come by now.

When Walt Disney went to build Disney World in Florida, he bought swapland for pennies an acre, under assumed names.

When it was discovered that Disney was doing something big in the area, the price for (worthless swamp) land around the park shot up to $1000 an acre.

/imagine what it would cost to get people to move out of the way of a hyperloop once they found out it was coming their way.

Now imagine these failures happening at 800 mph

I don't think "wheels in case of a lift cushion failure" is going to cut it.  800mph to 0 mph times need to be pretty long too unless you want to detach retinas. Some really crazy rocket scientists did whole experiments about how much G loading the body can take via rapid deceleration.

/I imagine at 800 mph hitting a solid object with a human body is kind of like a water balloon bursting.

I don't have to really, It's happened before in real life. Critical Velocity of a human being falling is about 120mph, you'd hit the ground, break every bone in your body and die instantly, but at least your meat would remain in it's sack for the most part.

See, that's why the tube needs to be airless so it can GO 800 mph, drag is a biatch.

You just seem to constantly underestimate the kinetic and potential energy involved in these things. Energy density and transfer is not your strong suit.

/I wonder how fast cruise missiles travel.... oh. only 500 mph...
//A hyperloop derailment would be catastrophic. Oh, if only I were XKCD and work out the energy expended in a ton of train going from 800mph to 0 in 100 feet.

And what did they discover?

Well, it doesn't really matter.  Lets just limit deceleration to 2G.  Won't be comfortable, but hey...this is an emergency.  Certainly won't detach retinas.  Wait a second...it only takes less than 20 seconds to go 800 to 0.  With 30 second headways, it looks like if I blow up my pod, not even one other pod will be screwed.
