Discuss future transportation system concepts or developments here. Tesla Motors' vehicles can be discussed here.



Elon Musk has FINALLY released his alpha design paper for the Hyperloop system he's been alluding to for over a year. I've read the paper, and everything looks remarkably solid. If this is developed, it could truly revolutionize regional transport (I can foresee particular benefits for densely-populated Europe).

The paper itself is located here.

Please don't discuss or ask questions about the system without first reading the paper. If you do, I will eviscerate you with words. You have been warned.

Enjoy smile

I had a quick look yesterday, read the non-technical part and quickly skimmed the technical part.

Perhaps more interesting than what he proposes is how he does it. He's attempting to apply the open source model to engineering, which makes much sense in a world with 7 billion people and modern communication. That has the potential of speeding up the process. For instance, a prime example of open source, Linux, is today used by thousands of companies on billions of devices. If software couldn't be reused and improved that freely, the wheel would have to be reinvented over and over again, and progress would be slow. (I recently found out, not much surprised, that my wifi SD card ran Linux and I was able to get access and compile new (open source) software for it adding much new functionality and basically making a new product in a few hours).

As for the hyperloop itself, I think the name is a bit strange. The construction reminds me of an aquaduct, but since it's not used for water, perhaps simply calling it a duct would work. The name needs to be short.

My initial thought on whether it's doable was pressure. With an inner diameter of 2.23 meters the volume is nearly 4 million m³ per 1000 kilometer. That slightly more than the KSC vehicle assembly building. The pressure mentioned is 100 Pascal. That's vacuum for many purposes. 99,9% vacuum in everyday terms. The surface area per 1000 km would be 7 million m². It sounds hard to avoid leaks. One leak would affect the whole length. Yes, pressure pumps would counter it unless there is a sudden, large leak in which case the whole system would have to shut down (and that would be expensive). It still sounds hard. I wonder if there is experience to be used from building pressurised oil or gas pipelines.

I am curious as to how Hyperloop will avoid motion sickness, since from inside no motion will be apparent, but you'll most definitely feel it. Can't find anything in the paper talking about such a thing, though maybe I searched the wrong keywords. I'll keep looking.

There isn't anything in there about it, but they seemed to describe what the experience would be like and why it should be comfortable for passengers. Anyway, feeling motion without seeing it does not necessarily cause motion sickness; people fly in airplanes every day, and in many cases the passengers cannot see anything outside to gauge their motion by, yet they usually don't get sick.

I imagine actually seeing out the window wouldn't be much better anyway... have fun passing trees at 700 MPH.

If we really want to fix traffic capacity, the solution is cheaper, quicker to implement and orthogonal to the alternative transport solutions. Most roads have sufficient capacity. The main problem is the commuting causing rush hours in the cities. Many of these commuters have office jobs. And many of these could just as efficiently or more efficiently work from home a couple of days a week. And if two cars stay at home, three cars will be removed from the road since those who still drive will get to their destinations faster. Videoconferencing, which is widely available at a quality way above Skype, suffices in most cases for the face to face contact people need with colleagues. Home offices wont work for everybody, but that's not the point. As long as some can do it, we'll be fine for many years even without road upgrades or new alternative transport. It's so simple that it's quite unbelievable that people seriously discuss multi-billion solutions requiring years of construction, when an option is at hand and could be implemented in months. To speed up the process, politicians can find some incentives. I don't know which incentives would work best, perhaps simply shifting some taxation, but politicians are creative and the experts in such matters, and they'll figure out something if they want to fix the problem.

Arthur C. Clarke predicted 50 years ago that people in the future wouldn't commute, they would communicate. All the technology foreseen for that and more is now available and inexpensive. It's about time to fulfil the prediction. Automated personal transport will come, but it will come at its own pace, I think. Meanwhile we have a simple workaround, and when we do have the ultimate transport solution, I'm not even sure that people would want to abandon the workaround.

A neat article on Nova's site about Hyperloop and other high-speed rail systems

http://www.pbs.org/wgbh....-trains

There is one issue they identified with the Hyperloop as not being discussed in the design paper which was in fact discussed in there, but otherwise a very good read. Puts Hyperloop into context with other modes of rail transport.

It looks like it's turned upsite. I don't understand the seats on pics 15-17. For normally sized people it's confusing whether they're meant for one or two people. Perfect for two kids, or one American.
