There were a references in the 3554 Amun article to some material from this book, but it wasn't in this article about this book. So I've copied it over. Since the values Lewis used are out of date (1997), I've added an update from the Platinum article, and copied the link (from that article) to a platinum commodities market price site. Not sure if that counts as original research? -- PaulxSA (talk) 22:19, 11 May 2009 (UTC)
Stating that an asteroid contains this and that much of a particular substance; ok. Stating that "it's worth" this and that many million US$ is just ridiculous. Prices change, and markets certainly would be disturbed by that kinds of amounts of material. To first state that shortage of resources is "...an illusion born of ignorance" and then quote market prices (markets = managing scarcity) is just self-contradictory and utterly clueless. Wish I knew how to fix without just deleting the whole crap. --Sigmundur (talk) 04:59, 23 April 2012 (UTC)
Yes, I agree, and space exploration advocates (of which I admit I am one) do this constantly. I think the point and value of such statements is really to suggest that the asteroidal and other extraterrestrial resources are simply "extremely valuable", likely dwarfing the large (and also poorly known) costs of accessing them. Let's see if some words to make this more clear can be put into the article. Wwheaton (talk) 17:07, 5 August 2014 (UTC)
