So one question that hasn't really been mentioned yet... What happens in the event of a fire? Do you just keep going? Stop the Fire suppression systems? Given any worst-case scenario.. how do you escape from the tunnel?

Or what if it breaks down and you're stuck in the middle of nowhere. How do emergency vehicles reach the pod if it is disabled in a sealed tube?

30 million people donating 200 each...totally doable.

Or 3 million people donating $2000 each for huge discounts on long term access. I would donate $10,000 if the discount was steep enough on long term use and included use of future expansions of the system.

Or better yet, sell tickets at a discount that can then be re-sold when the system is complete. Someone could buy $1M of reduced price tickets and then resell them for $2M when the system is ready. This way wealthy individuals wouldn't hit a maximum investable amount based on their personal expected use of the system.

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…

Musk is not financially Gates but he's already had a greater impact. PayPal, Telsa, SpaceX, and even that Solar company could easily be more important than creating the most successful PC operating system. The PC boom would have happened without Gates but Musk is pioneering entirely new business categories.

No he hasn't. He could, but not yet. We have other payment processors, car companies, solar companies, and we went to the moon over 4 decades ago. Musk is really awesome, but don't discount Gates. Frankly, his philanthropy might be more important than Windows, and the stuff that Musk has done.

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…

> take into account electrification costs (because it does get cloudy) Did Musk say his Hyperloop wouldn't be tied to the grid?

Yes. It says it is self-powering using battery packs and solar.

I have somewhere read, that large cities are usually the size one can travel in under an hour. So this could have quite interesting effects in effectively joining LA and SF.

San Angeles?

Offtopic, but please consider writing some blog posts or articles about your experiences working on nuclear submarines. That just sounds so cool, and while the work is probably dull, I'd nonetheless be fascinated to read some detailed stories.

Unfortunately I walk a very fine line about what is sensitive and what is not. I really couldn't go any deeper than what I posted here.

OK, then more like this please! ;)

The TSA phased out all the X-ray backscatter machines due to radiation concerns. All the scanners at airports use millimeter wave radar now. Still the same privacy concerns, but no ionizing radiation and thus no possible health concerns.

WRONG. Such machines are still in use and besides, neither machine machine has provably been better than plain old metal detectors. http://tsastatus.net/

Was this CNN article wrong then? I don't travel very much, but haven't seen an X-Ray backscatter machine since last year.

The R&D can't happen in government, but in some ways that's better - government projects are slower than this needs to be. What we need is for someone(s?) with deep pockets to bank-roll prototypes &c.

Sounds vaguely like maglev a couple of decades ago. It too was a neat idea on paper.

Except test tracks have been built or are being built, and it's sure to become a reality sometime or another.
