Could rust be the secret to next-gen computing technology? Current silicon-based computing technology is incredibly energy-inefficient and with climate change still a major challenge for humanity, finding ways to decarbonise tech is an obvious target for energy savings. Could rust provide the answer? In this talk, explore how the magnetic properties of oxides of common metals like iron (aka rust) might offer a solution, and learn how inspiration for this exciting research came from the most unlikely of sources: cosmic strings.
