What If? is a brilliant read from start to finish; I actually have the book, which includes even more fantastic articles. My favourite is 'what if you had a periodic table made up of the actual elements?'; the answer of course is 'boom', but at great length. (Which describes most of the content of the blog...)
What's interesting for this article is that Randall didn't really address the big point that 'a fireman's pole from [orbiting satellite] to the moon' is pretty much a description of a space elevator. An odd omission.
