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.

Imagine driving across a bridge near the North Pole, or going from New York to London in just an hour through a tunnel under the Atlantic Ocean. These are just some of the awe-inspiring projects of today's builders and engineers. Jaw-dropping computer animation illustrates the largest, most outrageous projects ever conceived. As students learn about stretching the boundaries of modern engineering, they also gain understanding of the technological design process and come to understand how physics and chemistry are utilized to solve modern human engineering challenges.
