"You have these at least two-millennia-old materials that when you combine them in a specific manner you come up with a conductive nanocomposite, and that’s when things get really interesting.”
This unique mechanism allows them to charge and discharge rapidly, making them ideal for applications requiring quick power bursts. The power capacity of a capacitor depends on its conductive plate surface area. Since the new “supercapacitor” concrete would retain its strength, a house with a foundation made of this material could store a day’s worth of energy produced by solar panels or windmills, and allow it to be used whenever it’s needed.As the cement reacts with water, a branching network of openings develops, with carbon migrating into these spaces, creating wire-like structures with a fractal-like pattern, resulting in a vast surface area within a small volume.
