Question by water_skipper: Would it be a good idea to power electric trains the way the Finding Nemo ride is?
Would it be a good idea to power electric trains the way the Finding Nemo ride is? Instead of having unsightly and unreliable overhead powerlines (catenaries) and instead of having a dangerous their rail, couldn’t an electric train receive the electricity wirelessly from something hidden between the tracks out of sight and out of reach? It seems to me that if electric trains are going to be built in cities at ground level an alternative would be used by now.

Any induction method like that wastes a lot of power, and the longer it is, the more power it wastes. That’s ok for an amusement park, but not for a 1000 mile length of track.
