Too late: http://www.seattlepi.com/technology/businessinsider/article/... > If you don't want to be searched at the train station, you have the freedom to not ride the train.

I wonder what the security checkpoints would be like on the HyperLoop if it ever got built? They are saying capsules could depart 30 seconds apart. Imagine is there was an attack in on of them, with several others travelling at high speed just behind. http://www.bbc.co.uk/news/world-us-canada-23677205 I'm sure there some contingency has been thought of, unfortunately it's just the world we live in these days :(

The pdf mentioned something like tsa, only streamlined.

The reason San Francisco built 269 units in 2011 was not bureaucracy, but that we were at the tail end of a real estate crash. More than 4000 units were started in 2012, and a further 30,000 have been approved. Source: http://www.spur.org/publications/library/article/san-francis...

Wake me when they actually happen (IE are built and available). SPUR's data comes from the SF planning department, which is now under tremendous pressure to at least claim they are doing something. Data on the actual ground (IE real estate listings, etc) do not support their claims, as anyone who tries to get a residential unit in SF can tell you. I'd love to know what they consider a "start". It shouldn't take multi…

Just because you're too ignorant and lazy to walk around looking at all the construction doesn't mean it's not there. There are over 4000 units actively under construction right now. That is a fact beyond argument.

I wouldn't be so fast to make that declaration. Elon Musk, Tesla, and SpaceX are pretty influential players right now, and I don't think anyone reading this white paper are anything less than wide eyed at the possibility that the future of travel is written right here and we could build it, for cheaper than the current slow expensive system. Influential people and money people and politicians are all going to read th…

I hope you're right, but in reality most people haven't even heard of Elon Musk. I've had to explain to many highly educated people what he has done, what SpaceX is, what Tesla is etc. While he's been rather successful so far, he's not in the clear when it comes to either of his companies right now, he's not exactly at the Gates level of success yet. I'm rooting for him though, he has the potential to be one of the m…

3 months ago, none of my non-tech friends knew who Elon Musk was. In the past month or so, I would say 50% of my friends now not only know who he is, but praise him and his work. I think that by the end of this year, you will be hard-pressed to find someone that doesn't know who he is.

> No toilet, and no way to get off, or even really stand up?

Seriously? It's like laying in a not quite horizontal bed for 30 minutes. If you can't plan your bathroom usage 30 minutes ahead of time, then don't use this transportation system (or wear a diaper). I can almost always hold it for 30 minutes after I am really feeling the urge to go. With 12-14 million trips per year, will there be accidents? Certainly. So that capsule gets diverted to be cleaned. Big deal.

> At least on BART you can move away from the crazy

It looks like those spaces are small enough that only 1 person could easily interact with you. If that's a problem, they could probably build in plastic dividers. Or you could just buy two tickets. If you can't tolerate that level of risk, then again, don't ride this thing.

I can assure you that there are plenty of people who are not bothered by these issues.

This system would seem very weak to criminals / terrorists / whatever firing bullets at it. It would be exceptionally difficult to track where the shot/s came from, and it would cause serious pressure problems.

As opposed to aircraft sitting on the tarmac, which are not subject to such problems?

Those numbers still seem absurd to me. $120 billion? France built the entire TGV network, about 2,000 km (1250 miles, ~2x the length of LA-SF, including numerous stations in urban areas) for around $20-30 billion. Maybe the U.S. should borrow some management practices from inefficient socialist "old Europe".

America is an inefficient, Socialist old Europe. $6.4 trillion in total government expenditures. Largest welfare and entitlement programs. Nearly 15% U6 unemployment. Collapsing labor force. Falling real incomes. 15% on food stamps. Massive fiscal mismanagement in every respect. Endless QE just to fund the government. 0% interest rates just to reach 1% GDP growth. Healthcare is clearly moving toward a completely soci…

I've been on one of the Chinese high speed trains and they are really impressive. The most striking thing about them is how smooth they are -- very little vibration at all, and very quiet. Far more pleasant than air travel, conventional trains, or anything else I've been on. Sadly, I think the first place a Hyperloop will be built is China. Chances are there are engineers there looking it over now, and figuring they…

That would be great, all you need is 1 country somewhere in the world to prove viable and it becomes a much safer political prospect elsewhere. Until a major accident at least like with Fukushima and nuclear.

You mean Chernobyl and nuclear, or Three Mile Island and nuclear? Both of those had already soundly killed the prospect for large-scale nuclear power in the US long before the earthquake in Japan.

Put plastic dividers between all the seats like they have in police cars. Problem solved.

Exactly. Best case, you'll kill 28 people. The other capsules will stop, and the hyperloop will be out of commission for awhile. Definitely not spectacular. They'd be better off attacking a more densely populated area. Much more hysteria...

If ALL Musk does with the Hyperloop announcement is shed more light on the potential debacle that is to be our $70b+ high-speed rail in California, we owe him a debt of gratitude. Really? Because it looks like this is an attempt to derail CA HSR using a proposal for an experimental technology that offers a fraction of what CA HSR does, but is potentially faster. CA HSR replaces/upgrades two metropolitan rail systems…

It is presented to provoke and I think you're right, it does look like an attempt to derail CA HSR. Instead, I think of it this way... if it's so cheaply do-able, then - do it! Sounds like an easy money making idea if you can build it for the figures proposed. While you may only need to charge $20 each way to break even, why not charge double what it costs to go the next most fast, convenient way, and you would make…

One problem is that the land needed to build it belongs to the state. Admittedly another is that a massive amount of R&D remains to be done and is not factored into the cost.
