Mars and Space Colonization

Talks about Mars and Space Colonization, to accompany my Science20.com column. 

See http://www.science20.com/robert_inventor039s_column

Articles I wrote include "Ten Reasons Not To Live On Mars - Great Place To Explore", "Asteroid Resources Could Create Space Habs For Trillions; Land Area Of A Thousand Earths" and "Might there be Microbes on the Surface of Mars?"

The talks could be about any of those topics and more, similar in range to the science20.com column except that I probably won't post about the music here. For the music see http://youtube.com/robertinventor and http://youtube.com/robertstunes
