Shimizu TRY 2004 Mega-City Pyramid, Tokyo
The dimensions of this sky city are nothing short of staggering. If ever completed the Shimizu TRY 2004 Mega-City Pyramid will stand 12 times higher than the Great Pyramid of Giza in Egypt at 6,574ft tall with an area of 3 square miles at the base. The structure would consist of 8 layers stacked on top of each other which would have a total area of 34 square miles. Each layer will consist of smaller pyramids each roughly the size of the Luxor Hotel in Las Vegas with layers 1 through 4 devoted for mixed residential and commercial usage and layers 5 through 8 for leisure and social facilities. There will be accommodation for 750,000 people, or 1/16th of Tokyo’s 12 million strong population. Getting that many people around will be a challenge met by a zero carbon, personalised rapid transit system and a network of accelerated walkways and elevators that connect the city via 55 strategically located nodes. The exterior facade of the proposed hyperstructure will be sprayed with a photovoltaic coating to convert sunlight into electricity for a greener city.
