5> Like-minded Engineering in Poland

Wow. What I’ve just learned…. I really didn’t think anyone would ever find my blog, let alone read it, so I’ve been doing my other things, which, for the last month and a half, has been living “off-the-grid” in a cabin in New Hampshire. No cell signal, no internet, solar and car battery energy only. It’s something I do. Anyway…
I got a comment, just one, that said, “looks like the “MISTER” system”.. with a link
Now I suppose anyone who has seen this blog probobly has figured out that I’m a bit of a closet engineer; How gratifying, then to find, out of the blue, that someone else has taken the same info, looked at the same problem, and come up with the same answer. I get it. They get it. There’s hope!
I am still in NH, with Wi-Fi internet only available at the town library, and me far from there, so “bear” with me (pun-fun) if I have missed something they said on one of their pages. I haven’t even read them all yet… but…
I’m a real fan of Bucky Fuller, even built a geodesic dome or two, but the use of the tetrahedron based track, I believe, is impractical. It may suit their purposes, as they, (wanna-be track suppliers) can bid track multiplying truss pieces, but there are, in my mind, real questions about assembly in the real world. Perhaps they want to be the only vendor for track, and feel that this design gives them a leg up, as any competing firm would need to duplicate work which they have already done. If the object is to help the world through PRT, then this is wrong-headed thinking. This is why this blog exists and why meaningful PRT implementations don’t. The flaw is in the business model. The previous and current model is “This is what you need, and we make and sell it”. The superior model is, “This is what the latest concensous is on this type of transportation solution, and we are vendors designing, building, problem-solving, into that evolving environment.”
I am also puzzled by how they expect to switch tracks. As a matter of fact, all of the really challenging engineering details are left out. What type of motors? How is electricity transferred? How does the computer system know where each car is?
None-the-less, I believe they are on the right “track”.

4> Here is My Idea of PRT

Notice the doubly articulated swing arm. This enables steep, even vertical ascension and dissention, as well as speedy, tight turns and rapid starts and stops. An adjustable hydraulic mechanism (similar to a door-closer) would dampen the swinging movement.
