I'm thinking boldly here. The French are able to peak at 200-230mph on operating trains running on conventional track. The Japanese and Chinese can push Maglevs up to 360+ mph. As a "disruptive" technology, 300 mph seems like it's attainable or at least worth considering.
It may require new approaches. It would be a monumental engineering effort. It would probably ensure full employment for a decade or more. But I don't think it's any more ridiculous than, say, sending a manned mission to Mars.
Unattributed, but per Wikipedia: "In mid-2011, scheduled TGV trains operated at the highest speeds in conventional train service in the world,[citation needed] regularly reaching 320 km/h (200 mph) on the LGV Est, LGV Rhin-Rhône and the LGV Méditerranée." [0] You're right, though, that this is different than average speed.
Still, 300 mph would be a stretch goal for sure, but it doesn't seem ridiculous if you're starting from scratch today. The Shanghai system was built over a decade ago. At minimum, automated computer controls should be significantly improved.
I'm also operating with the assumption that the budget for such a project would be unlimited, since it's just a thought exercise.
The distance from Chicago to Houston is roughly 1100 miles. Non-stop flights from O'Hare to Houston Hobby are listed on Kayak.com at 2 hours and 45 minutes. Add approx. 1 hour for pre-flight check-in, security and an average delay factor (it's O'Hare after all). That's a 3 hour and 45 minute trip time. We could add post-flight transportation from the airport to where you actually want to be and probably add another hour, but let's ignore that detail.
In 2007, the French TGV set a speed record on conventional track of 357 mph. The unconventional track (maglev) record belongs to the Japanese SCMaglev and is 368 mph [0]. These were set under very experimental conditions, but if it were possible to realize equivalent speeds in a practical setting (perhaps via underground tunnels), the train trip from Chicago to Houston would require only 3 hours(!).
But let's assume the above is impossible in real operating conditions. French TGV passenger routes regularly attain speeds of 200mph. This makes our Houston trip a little under 5 1/2 hours. That strikes me as quite efficient.
I'm not an expert, but given the deplorable state of American infrastructure, especially rail, implementation of a system like this would most likely require starting from scratch. As such, equivalence of the French TGV seems very attainable.
More likely, new innovation would lead to performance improvements over their system, which was conceived in the 1970s. Is 300mph attainable? I don't know, but it seems like a reasonable goal. That brings our Houston trip to roughly the equivalent of a flight, when including pre-flight check-in procedures. Of course, trains are safer, less energy and infrastructure intensive and a lot more pleasant.
All of this without mentioning the fact that SCNF, the operator of the French TGV, achieved a $1.75 billion operating profit in 2007.
This strikes me as one of those (many) pieces where TechCrunch (and the Silicon Valley elite) are too far removed to make an accurate assessment. Like colonial explorers, amazed by the "crude" methods of the peoples they encounter.
Libraries are one of few effective public resources that function to address class inequalities in our society. It's not just about access to information, but also a community guide for everything from how to vote, apply to jobs, and file a tax return. They provide entertainment by lending DVDs and CDs (think Netflix for those who can't afford $9/month), as well as books and magazines. They also provide free gathering space for tutoring, job training, and community building.
For millions in America, an iPad or eBook reader is equivalent to two weeks pay or more. For them, the end of libraries would be another sign that they're being abandoned and continue to erode the pretense that an "American Dream" exists for everyone.
I think the most concrete example of what you're describing is the "pattern" we saw with tobacco. Science suggested for a long time that cigarette smoking might be bad for you. As the evidence grew stronger, tobacco companies ran ads with Joe DiMaggio about how healthy their brand was[1].
Eventually the evidence was so irrefutable, and there were enough "casualties," that most reasonable people were forced to accept it.
This seems like a pattern that repeats itself. It begins with anecdotal evidence, followed by a long period of scientific research, then propaganda campaigns and eventual acceptance.
We're currently seeing it, about halfway through the curve, in the food industry with sugar. It's also happened previously with lead, seatbelts, asbestos, gambling, mercury, alcohol & driving, cholesterol, tanning booths, etc.
And now, perhaps, it's starting on the effect of information consumption. I use the term "information consumption" because it seems to be about much more than just teenagers and their phones.
