I wonder why it's so expensive. I agree with musk. It makes sense for humans to have a 3d transport system rather than 2d. The payoff is huge. Moving 200mph through tunnels is the future we should be aiming for. I also get a feeling he's read "foundation" from Isaac Asimov which talks about this.
I wouldn't want to live on Trantor, though

What? Are you serious??? If it's true then in US you are getting ripped off big time. The whole crossrail project is 73 miles with 14 miles of tunnels and 40 station and it has a cost of 15B£ (19B$ with today exchange rate). I cannot find the total cost of the tunnels, but apparently for 1.25B£ you can have 18km of tunnels: http://www.crossrail.co.uk/news/articles/crossrail-awards-ma... That is 1.6B$ for 11 miles. Ba…
Those Crossrail numbers give $0.2B/mile, including a lot of miles of track that aren't tunnels. After digging a bit I found this, which is a good summary: https://pedestrianobservations.wordpress.com/2011/05/16/us-r... It seems that $1B/__km__ (not mile, you're right) is sadly par for the course in the US, and Crossrail passes that threshold too. Projects elsewhere are below that threshold though.

Sure, ridiculing such information is easy, especially when you describe it as you have, emphasizing the easiest targets for ridicule. If your intent was to ridicule the information, I get your comment makes sense. But, IMHO, that's not a very substantive contribution for HN. IMHO, it would have been more worthwhile to highlight the less-easy-to-ridicule aspects of the page, such as the quotes from, and discussion abo…
The point that tim333 is trying to make is that the source you're citing is wildly unreliable. Take a look at their home page -- just on a first glance, I see: * Several videos about Pizzagate (and I don't mean critical examinations, either) * A number of anti-Semitic images ("Jews control the banks", etc) * A video literally titled "Hitler Survived WWII & Occult Nazi Scientists Developed VRIL Haunebu Foo-Craft (UFO’…
I linked to that page and specified NTBM. You could have substantially commented on the Los Alamos patents and their discussion on that page. But you chose to go off that page and to emphasize easy-to-ridicule parts. Please don't do that, thank you.

Care to explain how he messed this one up?
Because you are now more dependent on private cars for transport. Why would you use this instead of a system where you take a neighborhood bus to the local transit station & shopping center where you can pick up a light rail to the closest subway station, where you take the express train downtown to the high-speed rail station, where you take that to visit the next state for the day? No cars, and you can sit and read…

Remind me, what does the NS at the beginning of class names in the OSX frameworks stand for again? It's on the tip of my tongue. The technology Jobs believed in and developed at NeXT really did dominate the industry. It's in the phone I'm typing this on right now.
Completely fair (and cool!), but the use of nextstep at Apple is really a side-effect of NeXT failing to be what Steve wanted it to be (a competitor to Apple or simply successful).
I think Linux on the desktop would have been a better example though. Millions of hours of dev time have been spent on it and it's no closer to providing any competition to Apple or Microsoft now than it did in the 90s. I think there was a complacency in the Linux desktop world that success was inevitable given enough effort. I don't think Musk has ever been complacent about the success of his businesses. I don't think Jobs was either.

There is often enough a clear understanding why something is stupid. Freaking solar roadways got 2 Million and more. A City payed them 500k to install that stuff. It is not hard to calculate the stupidity of this. Especially of a couple who is doing this in a garage. There is a reason why big companies are not doing it. It has to make sense and money. This video above looks nice but if you think just a step back, it…
You can't have cars driving at 200 km/h on city streets.
It doesn't take to long is still much cheaper.
In munich you have a autobahn/cityring in the city. It takes perhaps 20 Minutes in city traffic to get onto the autobahn / highway.
There is a reason why we have only underground trains and why it takes years to build a new tunnel for them.
Also having the city traffic more autonomous would increase the traffic flow.
It's amazing to me the amount of negativity directed toward his projects and the millions of reasons people give for why they "won't work" (not necessarily on HN, but at least on general news websites). I'm starting to believe the only difference between those who start their own companies and those who don't is that the latter convinces themselves that it is impossible, never builds anything, and from their own lack…

At the peak times for the most used stations there is a car that frequently sure, but if use look at the overall system they don't send anywhere close to 60 * 24 = 1440 trains past every station in each direction per day. Further trains going to different stations often share the same track because you need more throughput in the city center than at the furthest stations. But, just because the edge stations get less…
The max throughout is the number that we should care about - they provide fewer cars per minute not because they're physically incapable of doing it, just because there isn't demand. And it would be the same in a car-centric situation as well - lower throughput in off hours.
Further, roads and bridges do get used from 2-4 AM when subway systems are generally not operating, so it's the use over the full day that's important not just peak usage.
