An ORNL invention proposes using 3D printing to make conductors with space-filling thin-wall cross sections. Space-filling thin-wall profiles will maximize the conductor volume while restricting the path for eddy currents induction.

Abstract electricity

Current battery materials such as silicon suffer from poor ion and electron transport due to non-optimal wiring. This invention facilitates particle interconnectedness to facilitate ion motion and electron transport overcoming poor assembly.

Recent advances in magnetic fusion (tokamak) technology have attracted billions of dollars of investments in startups from venture capitals and corporations to develop devices demonstrating net energy gain in a self-heated burning plasma, such as SPARC (under construction) and
