Elektroauto-Motoren und Windkraftanlagen verbrauchen tonnenweise Neodym. Und "unser" Neodym kommt zu 97% aus China.
Wie lange wird es bis zum 1. Klima-Metall-Krieg wohl dauern, wo die Ölkriege doch schon ein Dauerzustand sind... ;)
"Beijing announced last month that it was setting exports at 35,000 tonnes for each of the next six years, barely enough to satisfy demand in Japan. From this year, Toyota alone will produce annually one million of its hybrid Prius cars, each of which contains 16kg of rare earths. By 2014, global demand for rare earths is predicted to reach 200,000 tonnes a year as the green revolution takes hold. [...]
Environmentalists argue that this, coupled with widespread criticism of China’s stance during the Copenhagen climate summit, adds to the need for a “plurality” of rare earth resources. One campaigner said: “There are legitimate questions over Beijing’s control of these resources. Copenhagen showed they are not above putting national interest ahead of global efforts to curtail global warming.”
Once extracted and refined, the rare earth metals can be put to a dizzying range of hi-tech uses. Neodymium, one of the most common rare earths, is a key part of neodymium-iron-boron magnets used in hyper-efficient motors and generators. Around two tonnes of neodymium are needed for each wind turbine. Lanthanum, another REE, is a major ingredient for hybrid car batteries (each Prius uses up to 15kg), while terbium is vital for low-energy light bulbs and cerium is used in catalytic converters."
