Waarom het voor materialen van belang is
A turbine is mostly steel and concrete by weight, but the parts that make it competitive — the permanent-magnet generator and the copper in the nacelle and the export cable — are where the critical materials sit.

Copper
The reddish metal that carries electricity better than anything except silver, and which humans have been smelting…
Dysprosium
A heavy rare earth added in small amounts to magnets so they keep working when they get hot.
Iron & Steel
Iron with a little carbon in it, and the most-produced manufactured material on the planet.
Neodymium
The rare earth at the heart of the strongest magnet ever made — the kind in headphones, hard drives, wind turbines…
Boron
An element that makes glass resist thermal shock, fibreglass strong, and — with iron and neodymium — the strongest…
Praseodymium
Neodymium's near-twin, so alike that magnet makers usually do not bother separating the two and sell them together as…
