i can think of a bunch he missed that would have made my top ten: the perry people mover, powered by energy stored in a big heavy flywheel underneth, the r.h. and d. 18 miles of less then two foot gauge. 15" i think it is. the shonen and other monorails in japan where they are every day commuter transit railways. combining rail and tyre, there's a system called s.t.a.n., somewhere in france, i forget the town, that unlike that italian one, is actually dual mode and can follow the road or opperate indipendently. then there's the tuned resonence induction propulsion system that uses coils under the roadway, and various combinations of linear induction and mag lev suspension in reliable everyday use in many parts of the world. my own town has electric buses on several routes, that recharge from overhead charging stations.
