Ray, I wouldn't be happy until they were superconductor supported. Hot magnetic fields are expensive in power demand and a wheel is still an electromagnetic field support method, albeit on an atomic scale rather than a visual scale, so keeping the tracks super smooth is tricky. It's easier to make the gap larger and do away with some moving parts. In 1990, at the Tokyo science museum, our son and I saw little toy superconductor trains [and other superconductivity demonstrations, such as a rock melon supported on a ring of magnetic material]. Superconducting lines are the real deal. Supporting 'railcars' on superconductor magnetic fields then using electronically controlled wings to fly them would be pretty cool. That would do away with the need for continental aircraft. Especially if the railcars were travelling in partial vacuum tubes with photovoltaic-coated roof. When coming into a station, the air in front of the railcar would push a door open, avoiding air ingress to the tube by closing again when the train has left the tube. Then, open the next air lock leading to the next tube and fly through that one at 1000 kph. Easy to do really. No more airline crashes from a great height. No waste of time at airports. No bombs in aircraft causing mass deaths. No security checks to speak of. Very fast, very cheap, very clean, very pleasant, very quiet. No moving parts - a linear motor won't wear out. Low energy consumption. I should patent it. I'm working on my Graviton Spin Reversal System, GSRS [TM], to make it even more swanky. Then we won't need liquid nitrogen for cooling and special materials for superconductors. Mqurice
