Which softwares did you use to design the towers?

Since the design involves complex geometry, it had to be done using several parametric computing programs and techniques. But we always kept in mind that the construction needs to be simple and easy. Parametric Grasshopper was used for the design, the kinematics and mechanics were studied and simulated with Autodesk Inventor, and the 3D mesh with Autocad.

What materials do locals need to make the Warka Tower within their communities?

Warka consists of local and biodegradable materials such as bamboo, hemp and bio-plastic. Bamboo is the main material used for the frame structure. It is available locally in Ethiopia and can be found in many areas of the world. The mesh hanging inside the structure is under development at the moment. We are testing several materials with special coating that enables water collection. Atmospheric water vapor from the air condenses on the cold surface of the net, forms droplets of liquid water (dew), and falls under the influence of gravity into a container found at the bottom of the structure. The mesh technology is low-cost and relies on gravity and local weather conditions. The mesh will be custom made and produced, but the specific location for manufacturing it is to be determined.
