Alexander Graham Bell, father of the telephone, was also a huge fan of tetrahedrals—building everything from boats to planes out of the pyramid-shaped structures. This massive kite—built by the Queen and Crawford design house—brings Bell’s tetrahedral ideals into the 21st Century.
The experimental design was developed specifically by Sash Reading with Ivan Morison from the University of Westminster. It consists of 1700 3D-printed connectors linking carbon fiber rods that support cubenfiber aerospace fabric sheets. And as you can see from the video, the structure—dubbed Three Cubes Colliding—can actually be launched and brought airborne. That’s more than Bell could say of his three tetrahedral planes. [Wired]
