I believe that, when you see this picture, you might ask yourself....is this a futureristic building? or what is this? For your information, this is a building which is named as Shimizu Mega City Pyramid and it is using the "City in a pyramid" concept. Its height is actually 12 times higher than the Pyramid of Giza in Cairo, Egypt. The location to build this floating Pyramid is at the Tokyo Bay in Japan and it is planned to allocate about 750,000 people which are to be placed in a few dangling skyscrapers inside the mega structure pyramid like a fruit on a tree.
If this massive project is ready to be built, it will be the largest man-made structure on earth. For now, this project cant be initiated because of lack in technology. We cant simply use the material that we have now such as concrete because its a very heavy material and not strong enough. For this project, it is suggested to use a future available material which is super strong to withstand the weight of the structure an it is called Carbon Nanotubes.
In order to makesure the durability of this pyramid, the designers need to consider the present of earthquake and tsunami in Japan.
