The Massachusetts Institute of Technology’s news room announced plans by its architects and engineers to unveil The Digital Water Pavilion at the 2008 World Expo in Zaragoza, Spain. The Pavilion is said to include a café, an exhibition area and public spaces.
The Digital Water Pavilion will be made of liquid curtains for walls that will have the capability to be programmed to show images and messages. Another spectacular feature is the digital water walls will automatically part open when
it senses an object approaching.
Carlo Ratti, head of MIT’s SENSEable City Laboratory gives an example of understanding the concept of digital water walls:
“To understand the concept of digital water, imagine something like an inkjet printer on a large scale, which controls droplets of falling water.”
A row of closely spaced solenoid valves along a pipe suspended in the air, make up the “water walls” used in the structure. A computer will control the valves opening and closing at a high frequency. This will produce a curtain of falling water. Water and air will create a pattern of pixels. The display becomes a one-bit-deep digital exhibit that will constantly scroll downward.
“You could throw a ball at the wall, and then see an open circle drop down to meet it precisely where and when its trajectory intersected the water surface. And, with suitable programming, touching the water surface at any point can propagate patterns horizontally, along the wall, to other locations,” explains head of MIT’s Design Laboratory, William J. Mitchell.
Covered by a thin layer of water, the roof of the pavilion will be support by pistons that will move up and down. In the case of too much wind, the roof will lower. Another astonishing fact is when the pavilion is closed; the roof will fall to the ground and the exhibit will disappear.
This Digital Water Pavilion will definitely be a sight to see in 2008.
