I wasnt able to capture a video for this presentation, my battery dies, but Charles was kind enouhg to send me the power point for his presntation, of which I turned into a pdf. Charles turned a the topic of Green IT, into one of the most enjorabley presentations I have ever seen on the subject, and I know Mark Templeton got a few good laughs as well =)
