Hi, its me again, it bugged me too much to let it slip. 2007, so, yes, bloody repeats and lousy editing. Dr. Google gives you a whole list at 'TGV speed'; for example this one: http://en.wikipedia.org/wiki/T...
Now don't come and tell me 'Maglev' was different. On the contrary, without rails, it ought to go even faster. Plus, Maglev uses by definition more energy. Nothing against the Japanese here, but this is no more than an academic achievement. What's the point of using a system that consumes more energy for a lesser speed?
Oh, and don't come to me with the reduction of noise by avoiding the noise of the rails on a track. This has been debunked in the early 1980, when it was shown that the rolling of wheels on rails actually is the main noise component, but only for low speeds, beyond 180 or 250 km/h it is the displacement of air that produces the higher noise components.
I can only take guesses why the Japanese still try: to avoid the almost completely stonewalled intellectual property around the technological leader, the TGV. German Rail had tried to do exactly that: work around the patents used for the French TGV, at the loss of more than 100 lives at Eschede. I'll surely leave out the gory and sad details of that, however. Promised!
