Shimizu Mega-City Pyramid

The structure would be 2,004 meters (6,575 feet) high, including five stacked trusses, each with similar dimensions to that of the Great Pyramid of Giza.

The design relies on the future availability of super-strong lightweight materials based on carbon nanotubes and graphene presently being researched.

It started in 1982, when one of the employees went to see Blade Runner and saw the opening scene showing the two pyramids the Tyrell Corporation operated from.

[6] Transportation within the city would be provided by accelerating walkways, inclined elevators, and a personal rapid transit system where automated pods would travel within the trusses.

Housing and office space would be provided by twenty-four or more 30-story high skyscrapers suspended from above and below and attached to the pyramid's supporting structure with nanotube cables.
