Megastructures

As the World's insatiable need for oil and gas grows, companies are going deeper, into more hostile environments than ever before. Watch as we rip apart the largest oil rigs on the planet to reveal the secrets of these amazing technological achievements… and discover if they can survive Mother Nature's most violent forces.

South Korea never constructed a submerged tunnel, but now tackles the challenge of building one of the deepest immersed highways on Earth. Designed for the fickle conditions of the Pacific, the giant tunnel must be both earthquake and typhoon proof.

"I love what I do. I get to tear stuff up." Every day around the world, thousands of planes, trains, and automobiles get cut down to size for recycling. A jumbo jet costing a hundred million dollars becomes parts the size of beer cans in a matter of hours. An 18-ton steel rail car is attacked by some of the world's most expensive knives. And a fleet of automobiles dies a torturous death -the equivalent of an agonizing tooth extraction and an elaborate embalming ... all to process them for shredding and recycling. Finally, shredded metal is reborn as shiny new Land Rovers.

Planned to be one of the greenest buildings in Asia, and possibly the world, the Eco Ark aims to be a glowing example of how to turn a problem into a solution. Its walls are made completely out of recycled material.

Time was, if you wanted to leave earth, you needed a government ride. But in the very desert that helped give birth to the Space Age, Spaceport America will rise. The space version of an airport, it's a revolution in travel, with a revolutionary design to match. Yet the spaceport faces a world of hurdles. "Probably the most complicated project I've ever been on," says an engineer. The site sits in the middle of nowhere: no roads, no water, no power. And the spaceport won't be built unless a rancher controlling the land for a runway changes her mind.

To save one of the most iconic engineering wonders of all time requires the creation of another masterpiece: the Hoover Dam Bypass Bridge.
