1. A composite conductor element, comprising a non-metallic conductive porous matrix and a plurality of metallic copper particles incorporated therein, wherein:
said non-metallic conductive porous matrix is a randomly oriented matrix;
said copper particles are incorporated within a bulk of said non-metallic conductive porous matrix, and
said copper particles are arranged in clusters of metallic copper crystals having a size that ranges from 1 nm to 150 μm, and being connected to each other by metallic copper threads forming a metallic copper network on and within said bulk of said non-metallic conductive porous matrix;
the composite conductor element is characterized by an ampacity of at least 100 A/cm2 over at least 100 μm of the element, and is scalable and capable of forming macroscopic conductive elements.
