假设你是一位控制了全世界所有黄金的超级恶棍，决定把黄金熔化成一块立方体，那么这个立方体体积有多大？巴菲特说，全世界的黄金只能填满边长20米的立方体。计算很简单：根据最新数据，全世界所有黄金总重量为17.13万吨，一个重17万吨的黄金立方体边长应该为20.7米。如果堆在英国温布尔登中央球场，其高度只需9.8米。黄金可采量大约还有5.2万吨以上，多数黄金制品可以回收利用，但用在单个产品中的微量黄金可能难以回收（至少经济上不合算），它不是无限的而是可消耗的。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.
