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.
