Mega Cities

The Shimizu TRY 2004 Mega-City Pyramid was proposed as a concept for construction of a massive pyramid over Tokyo Bay in Japan which would solve Tokyo’s housing problems and become the largest structure in history of mankind. 
Although no one has ever had a glimpse at how it would look like, it is proposed that transportation within the mega structure would be provided by accelerating walkways, inclined elevators and a personal rapid transit (also called personal automated transport or podcar, is a public transportation concept that offers on-demand, non-stop transportation, using small, independent vehicles on a network of specially-built guideways) system where automated pods would travel within the trusses.
In this sense the image above might just be a steppingstone representing where we are heading to.
