All of the Baen Free Library can be downloaded in Kindle-compatible .mobi format.
Steve Miller & Sharon Lee's 'Liaden' space opera stories are some of the best out there, available from Baen. The Kindle store also has their short-story chapbooks for a couple of dollars each, and they are well worth picking up. (Note that if you get the full bundle from Baen, it includes the compiled edition of the first dozen or so of these chapbooks, so double-check before you buy.)

Sucrose Octanitrate.
Proof positive that with sufficient motivation, you can make anything explode.
