Good
article from the investment point of view IMO.
Snippet:
The electric motor in a Toyota Prius uses about two pounds of neodymium in its permanent magnets.
Each Prius battery also uses 20 to 30 pounds of another rare earth element, lanthanum.
It takes about a ton of neodymium for every megawatt of generating capacity from wind turbines.
