History of Oil podcasts

I recently came across another earth science-flavored podcast out there on the interwebs that folks might enjoy: A History of Oil. A strict adherent to truth in advertising, the podcast author/presenter is going through the history of everyone's favorite hydrocarbon in nice, digestible 10-15 minute segments. I've only listened to the first few episodes, but so far, so good! You can subscribe on that there iTunes! Enjoy!
