I'll start us off.
Blooloop posted an article about a patent filed by Disney:
I think the most interesting part of this is the fact that it can be added to existing rides. Which rides might suit this?Disney has filed a patent for a system that would allow ride vehicles on gravity-based attractions to change their position during the course of the track.
The system would allow fast moving roller-coaster vehicles to face left or right during the ride. This technology is rarely found on fast moving rides due to charging issues, making the development a new innovation.
The patent application is titled “Roller Coaster with Passenger Compartment Motion Powered Through Stored Onboard Energy.”
The patent explains that the technology can be integrated into existing rides: “a ride can be updated and modified by providing new show or visual features along the track that are visible not only as the vehicles travel in the DOT [direction of travel] but also on one or both sides of the track.”
