As electricity demand rises across AI infrastructure, mobility, and modern industry, a materials startup called Arcturus is taking a fresh approach to one of the grid's oldest challenges: heat loss in conductors.
The company says it has developed a process that infuses carbon nanomaterials into copper and aluminum using lasers, creating a material designed to move more electricity with less energy wasted as heat. In practice, that could let existing power lines carry more current without changing their size.
According to Arcturus, the technology could reduce electrical losses by as much as half, potentially freeing up around 3% more electricity on average and up to 10% during peak congestion. The startup says that kind of gain could matter across the grid, as well as in data centers, drones, robotics, and electric motors.
Founder and CEO Amir Mashal says the material is intended as a drop-in replacement for current copper and aluminum applications, avoiding major redesigns. That makes it especially attractive for power distribution equipment, busbars, and motor windings, where efficiency improvements can have a wide impact.
Arcturus has raised $8 million in seed funding, led by Initialized Capital with participation from Toyota Ventures, Breakthrough Energy Discovery, 1517, and Wireframe Ventures. The company is now scaling production beyond short wire samples as it prepares for broader testing.
If the technology performs as expected at larger scale, it could help shape a more efficient energy ecosystem for the next generation of connected devices, cleaner transport, and high-performance computing.
