Moving People
Question: what do aircraft, cars, buses, trucks, trains, ships and transport infrastructure have in common? Answer: people and copper.
Trains rely on copper for overhead power lines, motors, high-performance engine cooling systems, signaling systems and the explosive emergency shut down systems that can cut off thousands of horsepower in a thousandth of a second.
Copper connectors appear in aircraft engines, while airport lighting systems for aprons, taxiways and runways use thousand of metres of power cable.
Hybrid cars need up to 33kg for the electric motor, battery and wiring and all electric vehicles could benefit from the recently developed, highly efficient copper motor rotor.
