Callan's post on the TED talks reminded me that I wanted to post a TED talk I thought was very interesting. Despite living in the Rocky Mnt Region, I do on occassion scuba dive. I only have my open water certification, but I was enthralled with the development of this new technology to go deeper with minimal risk of oxygen/nitrogen toxicity.
Now, the development of this new technology opened up a whole new level of the ocean for exploration. Go check out Richard Pile's TED talk. Well worth the 17 minutes.
