Dome Over Houston

Season 1Episode 160 min

Dome Over Houston

Houston, Texas is in peril. The country's fourth most populous city faces hurricanes, heat, and the growing consequences of global warming. Only a radical solution can save the city, a solution that may lie with a massive dome, 1,500 feet high and a mile in diameter that will rise over the city center. To build the dome will require innovative engineering and construction on an unprecedented scale, with lessons, materials, and techniques drawn from around the world. From the Eden Project, the world's largest geodesic domes, to a tiny factory in Bremen, Germany, which manufactures a revolutionary plastic, the idea of a city-sized dome could finally become a reality.

Bering Strait Tunnel

Season 1Episode 260 min

Bering Strait Tunnel

The Bering Strait tunnel would connect Russia and Alaska, creating a high-speed rail line, freight route, and a crucial oil pipeline. Twice as long as the channel tunnel, it would be the most ambitious and expensive tunneling project ever attempted. To build it, massive Tunnel Boring Machines would start on both sides of the strait -- 64 miles apart -- and meet in the middle. On either side, workers would lay almost 4,000 miles of railway to connect the nearest rail heads to the tunnel. All this would have to be built in some of the most difficult conditions anywhere on the planet: permafrost regions, mountains and summer swamps, and an entire region known for frequent large magnitude earthquakes that put everything, and everyone, at constant risk.

City at Sea

New Orleans is under siege. Devastating floods caused by global warming and rising sea levels have brought the city to its knees. The old defenses -- levees and canals -- can't be counted on any longer. But surprisingly, some engineers are saying the only way for New Orleans to escape the water is to build a floating city: a New New Orleans, buoyed up by the water, not drowning under it. Long a dream for engineers, science has finally caught up theory. Innovations in nautical design, material science, and maritime construction have made it possible. But much more remains to be done. The city will have to survive killer waves, repel pirate attacks, and dodge hurricanes. The stakes are sky high, but the Big Easy is up to the challenge.

Mile High Skyscraper

Season 1Episode 460 min

Mile High Skyscraper

Shanghai faces a double crisis: overpopulation and urban sprawl. The Chinese are running out of room no matter how fast they build, so the city may implode. Under this crushing growth, Shanghai's economy, the health of its people, and the city's stability all lie in the balance. The solution could be building up, not out. And that could mean constructing the planet's tallest tower - at one mile high, it will be the world's first moving, breathing building. But to build it, engineers will have to overcome incredible obstacles and revolutionize the way we construct skyscrapers. Cable-less elevators would have to be invented, farms that grow inside buildings would be engineered, and windows that breathe and think for themselves could be created.

Underground City

Season 1Episode 560 min

Underground City

Chicago, Illinois is home to some of the country's most iconic skyscrapers, but with downtown real estate at a premium and with commuting times among the nation's worst, some have proposed a new solution: an Underground City. By building 1,000 feet directly beneath the Loop, the city could solve its space crunch and provide homes, offices, and more to tens of thousands of people. Drawing on lessons learned in Moscow - home to the world's deepest subway system - and Amsterdam - where planners hope to build beneath the city's canals, an underground city beneath Chicago is not only technologically possible, but might one day be necessary.

Personal Pods

Washington DC is a true traffic nightmare. Commuters waste 150 million hours a year in traffic, costing an estimated USD$2.5 billion in wasted fuel and lost time. City planners are out of options. Buses pollute and only add to the traffic mess. And the city can't expand its overworked Metro subway system fast enough to meet demand. But help may be on the way in the form of Personal Pods. It's a high-speed, non-stop, self-driving transit system that's been the Holy Grail for transportation engineers for half a century. An automated Personal Pod system would rewrite the rules of the road in DC, and be a model for new transportation systems worldwide.
