At $6232 on Amazon, this Nuclear Energy book for the Amazon Kindle is the most expensive ever. It's basically "a three-volume compendium of technical essays on energy." Product page.
It is 602 pages long, but since the Kindle edition of James Joyce's Ulysses, clocking in at 816 pages, costs less than a buck, that's not much of an excuse.[via Gizmodo - Amazon]
