"In addition, safety emergency exits and pressurization will be added in key locations.." How could anyone predict what 'key' locations an emergency is going to happen at? And how would eviction happen, given the tube's low pressure?

The Florida highway through the Keys dates to the 1930s and the NYC Catskill aqueduct to roughly 1916 - those are certainly great projects but aren't the last fifty. Largely agree with the rest of your comment though :)

Parent was specifically referring to the no. 3 aqueduct for NYC, which was started in the 1960s: https://en.wikipedia.org/wiki/New_York_City_Water_Tunnel_No....

Also, the highway through the Keys has seen very large infrastructure improvements over the last few decades, so while not a new project it is a significant civil engineering effort.

This is all rather absurd given that the Western European nations that haven embarked on major infrastructure projects in recent decades tend to have higher rates of unionization as well as stronger labor and environmental regulations than the United States. That Europe has high-speed rail and the United States doesn't can hardly be chalked up to unions.

European unions do not behave as American unions do. They seem to know how to balance their wants with the idea of allowing their host to survive, grow and succeed. American unions tend to extract as much blood as possible out of their hosts. They are really selfish, to the point of causing terminal damage. Look at the cities they've killed off.

American unions have not killed off any city. If you are trying to imply that Detroit was killed by unions you are gravely mistaken.

Can you name any new major civil engineering project in the US in the last fifty years? New San Francisco Bay Bridge. (No, it's not a refurbish -- it's a completely separate bridge with a separate design to replace the existing Eastern span.)

This one: http://en.wikipedia.org/wiki/Eastern_span_replacement_of_the... It only supports my point. It's 2.2 miles long. Construction started in 2002. It was supposed to open in 2007. It will not open until the end of this year. Total cost is currently at six billion. The Hyperloop is 400 miles long, will be built in seven years and will cost six billion. See my point now?

Since Hyperloop is 'Open Source', I wonder if the Chinese government will give it a go.

Wow, can you not abuse this wonderful idea for a political forum on unions , of all things?

There's a difference between theory on a piece of paper the the reality of building something. In the real world unions will be all over a project like this. Up every crevice. So will environmental groups and other special interest groups. None of this is good for any major civil engineering project. I asked a question in my post. Can you name any new major civil engineering project in the US in the last fifty years?…

Unions exist for a reason. Consider another large scale transportation project: http://en.wikipedia.org/wiki/History_of_the_Panama_Canal

Daniel_Newby is likely referring to the third aqueduct tunnel, under construction for ~40 years now. It's not small: http://en.wikipedia.org/wiki/New_York_City_Water_Tunnel_No._...

> No benefit to B through Y at all. So why do B through Y allow the tube to pass through? Easy. You pay them.

Easy? Think it through..... Who? How much? All the same? When? Then imagine all the people from B to Y who see an opportunity to screw the project for huge amounts of cash. Decades of lawyers arguing in court over every conceivable point, or opportunity. And that before environmental, and god know what else, groups get involved. Sorry, no, not easy at all. Not even slightly.

The high speed rail wasn't going to stop at B through Y anyway, and the hyperloop supposedly takes less space.

I think I'm going to have to go over michaelochurch's article again on unions and bloc voting power, which are very relevant to these ideas: http://michaelochurch.wordpress.com/2013/08/01/statistics-co...

Good article, until I realized he was setting-up to make an argument for software and hardware engineers unionizing. I did enjoy the first part though. To be clear, I am not one to say that unions are not necessary. I think they most definitely are in a number of industries. I am also not saying that union membership is evil in any way. A good deal of union workers are nice hard working people who are only after stab…

> Unions need to learn to be better citizens and to truly understand and partner with businesses. Then, and only then, everyone wins.

There's two sides to this coin. Businesses don't have a very good track record of treating their employees well without some outside influence like government or unions.

By the way, this comment here reads very differently from and much more reasonably than your "the goal of union leadership is to extract as much as they can out of the businesses they infect, even if this means their demise" rhetoric in the first comment.

What did Musk have to do with Space Shuttle program cancellation? I thought it collapsed under its own weight - disasters, costs, slowness etc. Please provide links if any.

Isn't that the case with planes also? As far as I know, at 35,000 feet altitude you'd die, too, if cabin pressure drops and the plane's life support system fails. And I don't recall ever hearing of an air plane accident that involved suffocation.

There have been a few, but they're quite rare. Two of the more prominent: https://en.wikipedia.org/wiki/Helios_Airways_Flight_522 https://en.wikipedia.org/wiki/1999_South_Dakota_Learjet_cras...

That Helios article is just terrifying
