whoever wrote that article might have done well to run it past a physics teacher.

would involve 82-foot-long, magnetically levitated trains that would carry passengers at roughly 621 miles per hour ... how much more precise than 621 mph do you want to get?

the train would pull power from the existing electric grid through magnetic fields ... psst, magnetic fields don't transmit power, you need electromagnetic fields for that. And if you really wanted to pull that power from the existing electric grid, I guess the line would need to run in extreme close proximity to existing power lines, no?
