Anyone familiar with ET3 (Evacuated Tube Transport Technologies), or Hyperloop? If so, what are your thoughts on that, and on the politically motivated "High-Speed Rail" in California? Ok, I just categorized this as Academic, but only because Science is listed in parens after it. Why can't Science be its own category, huh? Answer me that? =]

Feel free to reply to any comment by clicking the "Reply" button.On a small scale ET3 technology is as close as your bank. I would expect that acceleration/deceleration is the biggest problem to solve since thing force effects are most damaging to humans. Cost is a factor since scaling up is expensive and environmental effects may be severe. Musks boring technology shows promise. But then how do you line the hole so seismic shifts don't adversely affect the tube?

To be sure there is much to be learned. The technology has never been put into practice. Still, I am very excited about it and believe it will become a reality. It will be the next paradigm shift in transportation; displacing the airline, trucking, shipping, and most of the auto industry. It will shrink the world by many factors.
I like the one where you actually dig a straight-line tunnel through the spherical earth. We did this as a concept in AP physics 40 years ago. No, you don't go below the crust. The vehicle actually acts like a pendulum; drop it in New York and it comes to rest in LA. And then back again.

I think it's a great idea. I'm not sure we are currently capable of making that technology work logistically though. The cost seems to out weigh the benefit at this point as far as I know. I'd love to see it succeed though.

Half of the battle is political. This tech has been around since the 70s, but ET3 wants to use it in a meaningful way. Imagine commuting from SF to NYC in just over an hour. It will change the employment landscape worldwide. Plus it's green. HSR in Cali is laughable. We are spending BILLIONS AND BILLIONS on a choo choo train. Really?
