Extreme Engineering - Season 1 - Eps 4: City in a Pyramid
This episode features Shimizu's Pyramid City, which would include dozens of 100-story skyscrapers with more than a million workers as part of a giant pyramid on the sea to provide more living space in Japan. Concepts such as construction robots, electricity issues, and building materials are examined. The pyramid could withstand a tidal wave, and perhaps protect the city as well.
