Sustainability is one of the key themes at Dubai's World Expo -- and the Netherlands pavilion embodies the concept by placing an 18-meter-tall, cone-shaped vertical farm at its center.
Sustainability is one of the key themes at Dubai's World Expo, and with more than 190 countries represented at the six-month event, few have embodied that better than the Netherlands.
The brainchild of Dutch architect Michiel Raaphorst of V8 Architects, it's described as a"biotope" that aims to"unite energy, water and food," allowing farming even in places where the temperatures are typically too high, like in the desert heat of Dubai. A chimney at the top of the cone sucks in air to capture moisture and produces water through a condensation process powered by solar panels installed on the rooftop. With this technique -- developed by Dutch company SunGlacier Technologies and designer Ap Verheggen -- the pavilion can produce up to 1,200 liters of water a day. Some is available for visitors to drink and some is used to feed around 9,300 mint, basil and tomato plants dotting the surface of the cone.
