There was a bit of a stir when Google last week announced that one of the winners of their 10^100 contest would be Shweeb, a pedal-powered monorail from New Zealand that has elements of PRT. Google will invest $1M in Shweeb to help them build a small system, and if it makes any money on the investment, that will go into transportation related charities.
While I had a preference that Google fund a virtual world for developing and racing robocars I have come to love a number of elements about Shweeb, though it's not robocars and the PRT community seems to not think it's PRT. I think it is PRT, in that it's personal, public and, according to the company, relatively rapid through the use of offline stations and non-stop point to point trips. PRT is an idea from the sixties that makes sense but has tried for almost 50 years to get transit planners to believe in it and build it. A micro-PRT has opened as a Heathrow parking shuttle, but in general transit administrators simply aren't early adopters. They don't innovate.
What impresses me about Shweeb is its tremendous simplicity. While it's unlikely to replace our cars or transit systems, it is simple enough that it can actually be built. Once built, it can serve as a testbed for many of PRT's concepts, and go through incremental improvements.
