[Extreme Engineering][S1][E05]_Bridging The Bering Strait.avi
Bridging the Bering Strait- For the first time since the ice age, there could be a bridge across the Bering Strait linking Asia and North America. First, engineers must learn to deal with 55 miles of violent seas and crushing ice over the Arctic Ocean.
Transatlantic Tunnel- So, if you could take the train from New York and in less than an hour reach London, would you do it? What if you had to make the journey through a tunnel 150 feet under the Atlantic? And on a magnetically levitated train traveling at 5,000 mph?
Boston's Big Dig- How do you put a new, 10-lane highway 120 feet below downtown Boston without succumbing to crumbling earth, and without endangering the buildings and people above? It's happening right now.
Tokyo's Sky City- It would house 35,000 residents and host 100,000 daily workers, students and visitors. This space-age city in the sky might seem like science fiction, but it answers some questions about where humans might live as our most crowded cities become even more densely populated.
City in a Pyramid- Imagine a self-sustaining pyramid-shaped city in the air. And imagine that it is built by robots and with little help from human workers.
