Uh oh. Aren't we running out of nitrogen gas?
Oh, and besides the water and nitrogen, they
use chemicals as well...

    from the paying-the-price dept.
    [1]Anonymous Coward writes "Researchers at the United Nations
    University in Tokyo [2]studied the physical and environmental costs to
    produce one 32-megabyte DRAM chip. Their conclusion? The UNU team
    found that to make every one of the millions manufactured each year
    requires 32 kg of water, 1.6 kg of fossil fuels, 700 grams of
    elemental gases (mainly nitrogen), and 72 grams of chemicals (hundreds
    are used, including lethal arsine gas and corrosive hydrogen
    fluoride)."
