In 1942, silver was available when copper was in short supply so
$1,000,000,000, in 1942's terms, was used to build a centrifuge.  They
went to some effort to retrieve every scrap afterwards;  detail is on
Wikipedia.

    "How much do you need?"
    I replied, "Six thousand tons."
    'How many troy ounces is that?" he asked.
