Shimizu Mega-City Pyramid

The Pyramid City
The Pyramid City
The Shimizu TRY 2004 Mega-City Pyramid is a proposed project for construction of a massive pyramid over Tokyo Bay in Japan. The structure would be about 14 times higher than the Great Pyramid at Giza, and would house 750,000 people. The structure would be 730 meters above mean sea level, including 5 stacked trusses, each with similar dimensions to that of the great pyramid of Giza. This pyramid would help answer Tokyo's increasing lack of space, although the project would only handle 1/47th of the Greater Tokyo Area's population. The idea partially stems from the fictional architectural marvel of the Tyrell Corporation, which appears in the science fiction film Blade Runner (1982), as a duo of futuristic pyramidal structures.

The proposed structure is so large that it cannot be built with currently available materials, due to their weight. The design relies on the future availability of super-strong lightweight materials based on carbon nanotubes.

Dimensions

Perimeter of the foundation above ground would be 2,000 metres (2,200 yd). Area of the foundation is 8 square kilometres (3.1 sq mi). Infrastructure is an area of approximately 25 square kilometres (9.7 sq mi). Gross building area is about 88 square kilometres (34 sq mi) of facilities layers:

  • Layers 1 to 3: residential, offices, etc.
  • Layers 4 to 5: research, leisure, etc.

The height of each layer is 146.4 m (for 5 layers, the pyramid is 730m tall).

The pyramid structure would be composed of 204 smaller pyramids stacked eight high. Each of these smaller pyramids would be about the size of the Luxor Hotel in Las Vegas.

Usage

The building would be zoned into residential, commercial and leisure areas. 50 km≤ would be given over to some 240,000 housing units, enough for 750,000 people. Each building would have its own energy resources (sun and wind). About 24 km≤ would be assigned to offices and commercial facilities intended to employ 800,000 people. The remaining 14 km≤ would be used for research and leisure purposes.

Advantages and disadvantages

Some advantages include that this city would have more rapid mobility, that the city will be better protected from tsunamis, and that it helps solve the high-prices for land in Tokyo. A major weakness in this project is that if one truss fails the whole structure and 750,000 people will crash to the sea.

Materials and construction process

First, the pyramid's foundation would be formed by 36 piers made of special concrete.

Because the seismically active Pacific Ring of Fire cuts right through Japan, the external structure of the pyramid would be an open network of megatrusses, supporting struts made from carbon nanotubes to allow the pyramid to stand against and let through high winds, and survive earthquakes and tsunamis.

The trusses would be coated with photovoltaic film to convert sunlight into electricity and help power the city. The city will also be powered by pond scum or algae.

Large robots would assemble the truss structure, and air bladders would be used to elevate trusses above the first layer using a construction system proposed by Italian architect Dante Bini. Spheroid nodes at the connections between trusses would provide structural support and serve as transfer points for travelers.

Australian Company, Straight Edge Tiling have secured a contract for the internal tiling of the Pyramid. CEO Daiman Cartan met with construction engineer David Dimitric and lawyer Tavis Gorman in December 2007 to discuss innovative concepts regarding the huge task, as well as legal boundaries, to which an agreement was made.

Interior traffic and buildings

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.

Completion

According to Discovery Channel's documentary on the pyramid it would be completed by the year 2110.

The building would house itís own micro society. Included would be 240,000 housing units (enough for the 750,000 population). A large area of space would be allocated to offices and commercial facilities, which would provide employment for the communityís population. The residence and businesses would be powered by a portfolio of renewable energy technologies including: solar PV film, wind power, and even algae/pond scum.

This is a radical idea and isnít even close to being implemented. (We donít have the physical materials to build this structure; they havenít been invented yet.) But no great idea in the past seemed achievable when it was first dreamed up. The light bulb had 1000 failures before it had a single success. But that one success was all we needed to change the world as we know it.

So what makes this pyramid city so great?

    It provides clean rapid mobility for its citizens.
    The city will be better protected from tsunamis than modern structures being built today.
    It helps to solve the high prices for land in Tokyo (your living over water).
