I was reading through his patents, it looks like he has a lot of unnecessary/redundant technology. I can't blame him for trying to do something different. The inverted woodie would make for one wild ride.
He should be able to post renderings of his work. All he needs is a copyright, he already has a patent, so he doesn't have much to worry about. If someone stole his idea he would have some leverage to get some compensation.
Personally I think the ride could work, but would not be cost effective from a maintenance standpoint. Wood would have to be constantly replaced due to the stresses of being mounted on the side of a beam, rather than be cradled underneath.
The force controlled trains seem very odd to me. Even if you were able to control the G-Force going into the drop, you would actually be creating higher G-Forces at the bottom When the springs/pneumatics are fully compressed. The force control system is just an over elaborate fix for the old world vertical curves on a roller coaster. This problem was solved long ago with the lead in/lead outs of modern coasters.
Like I said, I'm glad he is thinking, but definitely over thinking. The sign of a good engineer is one that can solve a problem, the sign of a great engineer is one that can do it in the most simple way.
