The world’s first experimental maglev transit system using permanent magnets rather than electromagnets has carried its first passengers on an 800-metre test track in China—without needing a power supply.
Loz Blain writing in New Atlas, makes the following points:
- Maglev trains/vehicles are nearly silent, need little maintenance and use less energy to accelerate.
- Rare earths are required to make the electromagnets.
- China dominates rare earth production.
- A Sky Train costs about ten percent of a subway.
