re: NYC to London on a 4,000 mph vacuum train

There are many great ideas here, both pro and con. Vacuum environments seem like it may be a dangerous enclosure to live in, but space has been concurred. If they can accommodate all of the scenarios that may take place inside the tube, cracks, loss of vacuum, air, water, comfort, in years to come it may be something that might work. Who knows, people were skeptical about flying planes let along space flight.

Sylvie, Thank your reply, and expressing a willingness to make corrections. I apologize that my post could be interpreted as being "angry". Frustrated would be a better word to describe my reaction to "churnilism" reporting being so pervasive that even mostly original articles (like yours) tend to copy gross errors that have been repeated and repackaged dozens of times. As "Attoman" (hi VK) points out, inaccurate articles provide opportunity for many to learn about this emerging field. Fortunately many of the inaccurate articles have a comment section (unfortunately most "churalists" do not take the time to read the comments on the articles they copy, or to make corrections on the articles they write). Due to the dozens of articles, we are experiencing thousands of e-mails, many are incorrectly filtered as spam, or do not make it to the "priority inbox", and get a slow (or no) response. I will search for your important message, and reply.

Actually, Daryl, I did contact ET3. I emailed the contact address on your website and received no reply. Happy to do a more accurate follow up with you anytime! My email address is Sylvie.Barak@ubm.com As Attoman says below, it's always a pleasure to correct misunderstandings, and also to introduce new and novel concepts to people who haven't heard of them before. There is no need to get angry, just get in touch! I did, but sadly I received no reply. Email me anytime and let's get back on the right "track", so to speak. Best, Sylvie

Larry Niven described this system of transporation in his "Ringworld" series of books in the 70's. Science-fiction often point the way toward the future's "new" ideas.

Terraspan - Power to All the Peoples of the Earth Short Video - http://www.youtube.com/watch?v=zKXbx9ssONo Sylvie there is more then one "vacuum" transport system that has been introduced based in part on the 67 year old patent of Robert Goddard (the father of all modern rocketry-included the so-called German Rocket Science). What is perhaps most interesting about the system called "terraspan" (SEE terraspan.org at www.youtube.com) is that it is privately funded, entirely below ground and principally a POWER DISTRIBUTION AND STORAGE SYSTEM. Like the initial use of airplanes(for mail) the system will make money for investors by recapturing electrical power lost today and redistributing power across continents and from renewable sources to reduce energy dependency and carbon dioxide. After providing its power distribution functions terraspan will begin transport of freight and perishables at its max speeds. American chickens will first travel between New York and London the same way that they do today through european tunnels the long way around in minutes. Always underground even in the Bering Straight and the English Channel. Terraspan is underground in buried tubes or machine bored tunnels. Terraspan ties together the Americas. Then adds Eurasia through the Bering straight and eventually, Africa, Malaysia and Australia. One rides in comfort in terraspan and passes the long way around to reach London from New York. When fully tested and uber-reliable, terraspan is unlikely to exceed 5000 mph making the New York/London trip via Canada/Alaska/Eurasia 2.5 hours.

Heard and understood. It's PR Daryl, and a pleasure to correct misunderstandings, among those who moments before knew nothing of the ET3 idea. All the best!

Ooh-oh, and for the London-NY "train" they shouldn't forget to extend the vacuum tube by 3cm every year, due to continental drift! :-)

My biggest concern is that at 4000mph you have to guarantee your environment over an incredible distance (the stopping distance), where as planes have some degree of maneuverability and trains a shorter stopping distance in the event of problems. Also maintaining a vacuum over such a surface area is going to be an interesting challenge.
