System Design
Go-Tube design is inspired by the Hyperloop proposals put forward in August of 2013. The idea that we can jump forward in performance and value by an order of magnitude is highly attractive, but it appeared there were unsolved problems with the Hyperloop design. While Hyperloop was starting development and examining feasibility Go-Tube grew from a spark of an idea into an initial computer model and an increasingly detailed proposal. The question of how to fund and build has driven initial business plans using an open source model similar to Hyperloop. Any patents obtained will document and secure access to the ideas under development and those built upon them, using the open source and creative commons models.
The design is intended to provide three smooth, straight, transparent evacuated travel tubes within an enclosing solar film covered tube. The travel tubes are kept as near as possible to a constant temperature to prevent dimensionally destructive "working" of the tubes by thermal stresses and to allow reduction or elimination of expansion joints. Go-Tube is effectively a long greenhouse, subject to high diurnal and seasonal thermal load cycles so temperature management is a serious challenge.
There are a number of issues related to securing smooth, strong, stable glass tubes with consistent dimensional accuracy at a reasonable cost, not to mention resistance to failure and controlled, safe failure modes in the extremely rare event of overwhelming destructive forces. The three dimensional fullerene geotruss requires a huge amount of construction grade carbon fibre composite. An example 300 mile long tube is expected to use the rough equivilent of the entire world's annual supply for all other purposes.
It is considered highly desirable to allow passengers a direct view outside to orient themselves during the trip, we believe that while it may be initially thrilling to experience 600mph 30 feet above the ground, passengers will acclimatize and use the cues from the view to adapt kinesthetically to the experience and that many will enjoy and prefer this. A simulation of the view is in the planning stages and will be created of at least one potential route.
