“without Chinese neodymium magnets”
Neodymium magnets date from the 1980s.
When I was a kid, they used AlNiCo magnets.
Ask an AI how much more magnetic field is in a neodymium magnet vs AlNiCo. Or trust me. It’s 10X.
That means 1/10th the electricity from non neodymium magnet-based generators vs neodymium based.
2024 US imports from China 7500 metric tons of neodymium magnets. 2024 US production of neodymium magnets — 0 tons.
For drones, range will be 1/10th. Ditto Tomahawks and the electric motor powered guidance fins. The battery dies much faster with an old style magnet. You can’t build new ones without total redesign, bigger batteries (and more weight so again, shorter range).
Pop on over to Google Earth and have a look at the gargantuan Chinese mining and processing complex at Baotou.
We have nothing. For about 10 years.
