43min - Houston is in peril. The country's fourth most populous city faces heat, hurricanes, and other natural disasters. Only a radical engineering solution will save the city: a massive dome, 1,500 feet high and a mile in diameter.
43min - 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 tunnelling project ever attempted.
44min - Washington DC is a traffic nightmare. But help may be on the way. Personal Pods -- a high-speed self-driving transit system, would rewrite the rules of the road and be a model for new systems worldwide. But the car is not about to give up without a fight.
44min - Chicago -- home to some of the world's most iconic skyscrapers. But the city's future may actually lie underground. A new city 1,000 feet beneath the surface could solve its space crunch. It's not only technologically possible -- it might be necessary.
44min - Shanghai, China faces a double crisis: overpopulation and urban sprawl. No matter how fast the Chinese build, the city may implode. The solution could lie in building the planet's tallest tower-and the world's first moving, breathing building.
44min - New Orleans is under siege. The old defences -- levees and canals -- can't be counted on any longer. But some engineers are saying the way to save New Orleans is to build a floating city: a new New Orleans, buoyed up by the water, not drowning under it.
