Canada's NEW Invention Could Replace Iron FOREVER

In 1907, the Quebec Bridge collapsed into the St. Lawrence River under nothing but its own weight, killing 75 workers. For three thousand years, strength has come bundled with weight. Iron and steel carry the modern world, but they also carry themselves, and that limit is written into the physics of scale. This is the story of the long hunt to break that rule. It starts with Galileo's insight about why giants can't exist and Alan Griffith's discovery that thin glass fibers are far stronger than thick ones. It runs through nano-scale 3D printing at Caltech and in Germany, and the stubborn problem that kept those lattices breaking at the joints. It ends in a University of Toronto lab, where a team working with KAIST used machine learning to design carbon nanolattices with the strength of carbon steel and the lightness of Styrofoam. Along the way, we look at the truth behind the Iron Ring myth, and at whether this invention could ever replace iron.
