Jerry: That was my bench model. I once had a website, but my server actually deleted it when they changed over to do their mail through Yahoo, and my backup disc had gotten lost.
I try to explain to people that this was my first attempt. I should not built it with wood, but an illness forced me to cut corners. The real guideway was planned to be half the width of the cars. It looks like crap. However, if you time the arrivals and departures at that little platform, you will find it does something that nothing else can....about 8 per minuite.
You may even see a little collision there, from a picture where I was trying to see what would happen if I sent 2 cars into a station built for only one. The person who made the video for me was told not to use it, but he thought it was "cute". Free help, so I suppose I shouldn't complain. He also strayed from the dialogue I had written.
I had hoped peoplke would realize that this was just a bench model, and that the eventual product would not look like this, but would operate this way. However, most do not. The cars in the model were manually controlled, and a computer would do better.

The bench model is 1/12 scale. No, I don't want to try 1:87.....cars would be 1.3 inches long, track less than 1/2 inch wide, and the small parts almost too small for me to see and assemble.
I suppose a toy company could mould all the parts from plastic, but that is an undertaking that I can't handle, for various reasons.

Because of the electronics, I don't think that a scale model could be
built at such a small scale, unless it was just for viewing. In order to
be effective, it would have to operate. I/we came across LIMs that are
made for house curtains. This could be done with a fully operational
model, but larger than 1/87.
Would you be interested in gathering more specs on cost? The engineer
that built the Skyweb model said that if it were to be accurately built,
he could see an expense of $50,000 to $80,000. I'd be willing to try to
organize CPRT groups for the effort. I think that some funds could come
from grants. Maybe Podcar might be interested...(??)

We built an operating, radio-controlled 1/5th scale model of our base
vehicle plus a rather crude guideway very early in the development process
to prove that our steering and switching concepts were satisfactory. We
used this operating scale model to perform validation testing of our
concepts. I have forgotten how much we spent, but it was several hundred
hours of engineering and shop time. It was well worth the effort.

This is more like what I did with my model. I had spent a lot of years putting ideas together, but you can do this forever without knowing that it will really work as planned. The scale model was more for ME than anybody else, just to make sure it worked as planned.
If I had not done this I would have been making claims that I was not really sure of. If an engineering model works, and engineer who is worth much can build it bigger, much nicer looking, and maybe even better. You can learn from the model just where improvements can be made.

We ran into the fact that there are Linear Induction Motors (LIMs) for
curtain rods for houses.
Could be an interesting project.

I don't think I ever said that such a scale could not be done, just that I don't care to try it because the parts are so small. For example: These little train bogies look like they have a motor that is only about 5/8 inch long. I could have used a lot of those in my system except that the rest of the bogie was useless to me. I would have to build tiny little reduction gear-boxes, to give me what I needed. I had to this for my model, but with slightly larger parts.
Skyweb Express would be the same: Use the motor, but build your own bogies with 8 tiny rubber wheels and the appropriate reduction gearing. That can be done, but not by me, with the equipment that I now have and the eyesight that is no longer perfect, due to age, etc.

Correct, but deosn't Skyweb, or whatever it is now called, use a little 8-wheel bogie enclosed within the guideway to support and move the vehicle? A scale model should duplicate whatever the real system is to be, shouldn't it? Jack Slade

It would have to look and act like a real PRT system. If it had
features like a number of systems, we wouldn't be promoting just
one system.
Set up in a mall, it would certainly draw attention. Politicians
couldn't say that it wouldn't work.
Dick
Politicians couldn't say it won't work? Of course they will. Politicians will say anything stupid that serves their purpose. They learned a trick from "Mein Kampf".....namely, "if I tell a lie, tell it often and loud enough, eventually 85% of the people accept it as true". Not an exact quote, but close enough.

Jack - you attach your body to the bogie. As long as the bogie has sufficient power to move your body at the desired speed, there should be no problem. As for rubber tires, I would just glue a rubber washer to the plastic wheels which are already attached to the bogie.

It could.I'm leaning towards NOT trying to duplicate Skyweb. Instead, using 3-4 development ideas.Right now, off the top of my head,
- Vehicle sort of like Skyweb - Modutram - Skycab. They're similar.
- Guideway sort of like Vectus - Raytheon - Modutram. They're tubes. For a scale model, sch40 PVC.
- Motors in-track LIMs like Vectus. The home curtain rod LIMs would do, I think.
- Controls are a BIG ???
- Maybe 3-5 stations.
- Full sized Skyweb - Vectus type stanchions where people could actually program a vehicle and watch it move from in front of them to a chosen destination.
It would have to look and act like a real PRT system. If it had features like a number of systems, we wouldn't be promoting just one system.Set up in a mall, it would certainly draw attention. Politicians couldn't say that it wouldn't work.
