During our 11 minute plus discussion, John, Dr. Elvis & I discussed the work done by Dr. Elvis in mathematically figuring out the potential number of commercially viable asteroids. During the segment, he explains how he created his formula, he went through key assumptions with us, we talked about Delta V needed to reach the asteroids, the Delta V for the return trip with ore on board, and showing how this determines the minimum size for an asteroid of commercial value. He also said his analysis is probably on the conservative side and with more data, he can refine his analysis. I am listing the URLs and articles that have reported on his work as he publication gave his work a different slant: BBC: The headline gives the wrong impression, though the article is fair enough (http://www.bbc.co.uk/news/science-environment-25716103). Dr Elvis told BBC News: “I want to stress that my paper does not mean that there is no commercial future for asteroid mining. It does mean that gold mines are rare, which shouldn’t be too surprising. Not every mountain on Earth hides a fortune, and not every flying mountain in space will either.” New Scientist had it first: www.newscientist.com/article/dn24696-alienhunting-equation-revamped-for-mining-asteroids.html#.Utf6F3kTs2Q. Wired.co.uk: www.wired.co.uk/news/archive/2014-01/14/asteroid-mining-not-viable where they correctly say “Elvis does, however, continually point out in his research paper that the estimates are conservative, and that far more work needs to be done to improve upon these predictions. In fact, the paper is more of a call to action that a warning from a naysayer.” Newser: www.newser.com/story/180656/there-are-only-10-asteroids-worth-mining.html; Mining.com also has a good summary: www.mining.com/is-space-mining-commercially-viable-22553; They are all picking up off Slashdot (http://beta.slashdot.org/story/196587). 100s of comments, not all really to the point. Slashdot got it from a good summary at medium.com (https://medium.com/the-physics-arxiv-blog/e0063699d199).
