Let me say this: I hate flying on commercial airplanes.
If a terrorists' job is make me feel endangered and vulnerable in places like an airport or on an airplane, then he is terrible at his task. Between the cameras, security, dogs, air marshals and everything else, there are few places I feel as safe as at an airport. However, if said terrorists' intention is to make me get extremely bored and frustrated as I wait in line for someone to take near-nude photos of me, and suffer the explanation in differences between 3 oz. and 4 oz. travel bottles, well then that terrorist has definitely earned his martyrdom.
What else do I hate about flying? Nickel-and-diming. The ridiculous screenings. Checking and then losing luggage. Being stuck on runways. Flying coach (which is really all I can afford). Eating terrible cabin food. Sitting way too close to sweaty strangers. Having about 8 inches of leg room and a seat that "reclines" (more like jostles) a few centimeters. The oversensitivity.
I could go on, but why bother? After all, just a few years ago U.S. President Obama allocated $12 billion towards developing high speed rail here in the U.S. This plan should transform the nation's outdated railways between a couple dozen U.S. cities into super-speed people movers. Amtrak officials see a day where taking the train from Boston to Washington D.C. takes just three hours, whereas today it takes at least 6.5 hours. Such infrastructure upgrades would mean air travel is relegated to cross-country and international trips, and would reinvigorate a stagnant railroad industry. Amtrak indicates that 20% of the U.S.'s GDP is generated between five urban hubs located in the Northeast - Boston, New York City, Philadelphia, Baltimore and Washington - and that failing to provide these cities with high-speed rail undermines the nation's economy.
But absolutely no high-speed rail construction has resulted from the $12 billion, as of yet. California's high-speed rail plan is closest to fruition, with track upgrades and bypasses being implemented, but no new track has been laid. By 2017, the first 130-mile stretch of dedicated high-speed rail will be completed between Fresno and Bakersfield. And by 2040, (yes, 2040) it's estimated that the final high-speed lines will be set between Los Angeles and San Diego.
At this rate of progress, high-speed rail will be obsolete by the time it's ready. On August 12, Elon Musk - you know him from PayPal, SpaceX, Tesla Motors, Solar City - will announce his newest project: the Hyperloop. It's certainly ambitious, as it's expected to reduce travel time from Los Angeles to San Francisco to just 30 minutes, which high-speed rail pegs at 2 hours, 40 minutes. Musk calls it a "cross between a Concorde and a railgun and an air hockey table."
The Hyperloop would incorporate maglev trains inserted into a tube system which is vacuum sealed. The lack of air resistance and friction would enable the train to reach speeds of 700 mph with relative ease. Energy requirements would be very low, and if the system is placed above ground it could even be energy positive with solar panels. Musk claims his design can never crash and is immune to weather. It is likely very similar to the tube transport systems found at bank drive-throughs, which use a series of high and low pressure air columns to move canisters within the tubes. Artist John Gardi thinks he's uncovered Musk's design based on his statements.
While the idea is fresh, the innovations that make this design possible are not. Similar designs, known as vactrains, were patented as early as 1945, and dreamed of decades earlier. The most notable difference between vactrains and the hyperloop would be the speed; vactrains would be capable of reaching 5,000 mph. There would be no sonic boom, and the train would accelerate via gravity and magnetic levitation. In the 1970's, an engineer named Robert M. Salter proposed a collection of vactrains which would provide regional travel in the U.S. at 3,000 mph. The concept was improved to the point where a worldwide subway system called PlaneTran could provide intercontinental travel in just a few hours. (Beijing to New York? 2 hours.) Clearly the designs were never pursued, but the concept keeps popping up whenever improving rail travel becomes a political topic.
Elon Musk wants to dissuade the U.S. and California governments from pursuing high speed rail any further, but it's going to be hard to convince politicians to abandon a plan that provides jobs, infrastructure spending, and photo opportunities. While Musk's Hyperloop would cost about 1/10th less, it will be impossible to construct without the government's endorsement; multiple rights issues stand in the way.
Rail travel stands at a crossroads railroads rail-crossroads in 2013. It's up to bureaucrats to believe in something radical and altruistic, even if it's a little eccentric. Unfortunately, I don't have much faith that I'll see the Hyperloop or a vactrain in my lifetime.
