This is a good one.
TransportEnthusiast, who is still having great fun poking sharp sticks at the anti-PRT trogs at the Seatle P-I local transit forum, happened to mention in passing:
I'm curious to see how ULTra performs, but I'm really more intrigued by the LIM designs. Source
Ken Avidor, aka PRTskeptic, commented thusly:
Typical... PRTers don't just move the goalposts... they make them up. [ellipses in original]
First Morgantown is PRT, then it isn't... then Raytheon... then Skyweb... then UlTra... [sic; ellipses in original] now "LIM".
There will be others and the old ones will end up preserved forever in Jerry Schneider's gadgetbahn museum. Source
Why does Ken think a preference for a LIM design invalidates other PRTs? Because, as usual, he doesn't know what he's talking about.Ken is supposed to be "perhaps the leading skeptic" of PRT, says he has the facts and knows his stuff. And yet he is so ignorant that he doesn't know that LIM is not a PRT design, but stands for "Linear Induction Motor," which some PRT concepts are choosing to use, but others aren't. LIM is a type of magnetic motor that is already employed in a wide variety of every day uses—including the Vancouver SkyTrain and the Kuala Lumpur "Putra" light rail.
The "PRTskeptic" doesn't even know the details of the light rail technology he champions. Now then: who belongs in a museum?
gPRTKen Avidor does not currently exist in successful public operation, and, in all likelihood, never will
