LA to SF in 6 minutes? Meet Elon Musk's 4,000 mph transportation concept, the "Hyperloop"

40. You haven't thought this through, have you?

I always like your perspective, but frankly on this one you sound like Marie Antoinette endorsing the consumption of cake. A lot of those air travelers would rather be doing almost anything else, but their employment demands their participation. Sneering at them seems out of character for the you I've come to know.

Aircraft servicing this market contribute appreciably to the problem of climate change and air travel isn't going to disappear because people want to be climate friendly or adopt a "slower" lifestyle.

We are working on alternatives to reduce or eliminate GHG emissions related to the demand for high speed travel, but the options aren't materializing very quickly. Biofuels are the most promising, and in areas of higher population density high speed rail is a good approach. I'd consider these more likely than what Musk is hinting at, but I might change my mind once I hear the details next month.
