It's one thing to tunnel under a river that is 20 ft. deep. It's a whole other story to tunnel under something that's 2 miles deep. That's in addition to the steep grade down the continetal shelf.<BR/><BR/>Combine that with the fact that there's a high probability of hitting molten mantle under the ocean floor.<BR/><BR/>Unless you were just kidding, right?Unknownhttps://www.blogger.com/profile/18382275057184120210noreply@blogger.comtag:blogger.com,1999:blog-6609536178570975752.post-90562677462154485772008-10-28T19:54:00.000-07:002008-10-28T19:54:00.000-07:00Of course when it reaches 7.5km/s it no longer nee...Of course when it reaches 7.5km/s it no longer needs levitation :) Now if it then exited the system with a sufficient angle you'd have a cheap launching system for free!<BR/><BR/><A HREF="http://njhurst.com/aether/blog/01220238869" REL="nofollow">How fast can a train go?</A><BR/><BR/>With electronically steered maglevs passing is no longer an issue - you just make the track wide enough for multiple vehicles.<BR/><BR/>More practically, I think maglev is limited in speed by inductance, much like rail guns (which are limited to something like 2km/s).njhhttps://www.blogger.com/profile/15278712220761294549noreply@blogger.comtag:blogger.com,1999:blog-6609536178570975752.post-70088233552720903492008-10-28T19:52:00.000-07:002008-10-28T19:52:00.000-07:00well if you're going under an ocean the curves thi...well if you're going under an ocean the curves thing shouldn't be a big deal, and 10 min headways with a train that can carry hundreds, if not thousands of people... looks fine to me.whiteguyfromtheprojectshttps://www.blogger.com/profile/10547750507431578651noreply@blogger.comtag:blogger.com,1999:blog-6609536178570975752.post-52845790227851594762008-10-28T18:33:00.000-07:002008-10-28T18:33:00.000-07:00Jonlin, there's an upper limit to how fast a vactr...Jonlin, there's an upper limit to how fast a vactrain can go. Beyond a certain point, headways become too long, acceleration takes too much time, and corners are insane.<BR/><BR/>For example, if a vactrain behaves like a good subway with regards to acceleration and yaw, then at 1 km/s, it should take 15-20 minutes to accelerate to full speed and 15-20 minutes to decelerate, have headways of at least 10 minutes, and be unable to negotiate curves of radius less than 500 km.Alon Levyhttps://www.blogger.com/profile/12195377309045184452noreply@blogger.comtag:blogger.com,1999:blog-6609536178570975752.post-26550917374738647212008-10-28T15:55:00.000-07:002008-10-28T15:55:00.000-07:00Could be our marvelous solution to finding a metho...Could be our marvelous solution to finding a method of intercontinental travel that doesn't use too much gas... although I like the mag-lev in a tunnel with all of its air removed so the train can go 2000mph under the Atlantic better...whiteguyfromtheprojectshttps://www.blogger.com/profile/10547750507431578651noreply@blogger.com
