Heinlein's "The Roads Must Roll" posits a network of very fast, very long moving walkways which could be used for mass transit (you'd ramp up speed on slower ones then hop over to a fast one). Wikipedia says that moving walkways had been in sf for decades by that point, but Heinlein also almost incidentally invents the Segway in the story -- just a little treat.
I love peoplemovers (like the Hong Kong Central-Mid Level escalators and the delightfully bouncy SFO walkways) and always wondered what would have to be different for us to get super-fast ones for transit.
In Boston, IMO they would be at least as good as the Green Line :)
