Vertical farms, smart ceilings and national pride at the world fair
Expo Milano is a makeshift city studded with spectacular pavilions. In an attempt to outshine each other at the world fair, which opens today, 143 countries brought in their A-list teams of architects, innovators and culinary experts to design their temporary buildings. The UK built a beehive structure that's straight out of a sci-fi movie. China has an elaborate floating roof. Italy used air-purifying cement for its palazzo. And while the US pavilion isn't an architectural extravaganza, it's a didactic display with a giant automated vertical farm that's the first of its kind and size.
