If you want a credible reference, read “Maglev America” by James Powell and the late Gordon Danby, decorated inventors and holders of the patents for both first- and second-generation superconducting maglev. The book is available on Amazon. I think that you are already aware of this but I guess that you feel the need to repeat that I have no credibility whenever I comment online, perhaps to influence first-time readers. Powell and Danby were awarded Franklin Institute medals for excellence in engineering, joining some pretty good company like Alexander Graham Bell, Thomas Edison, and Albert Einstein. For me, Dr. Powell and his team have a lot more credibility than the politicians and contractors who continue to tout this “blood sucking” steel wheels system.  We may not be able to kill it but we can change it to 21st Century technology.
