Daddy, Papa and Me

This is just cool. This Australian man has spent 13 days in a submersible. His oxygen comes from algae he pees on and his electricity from bicyling. When I was a kid, 4th-6th grade I think, I used to draw pictures of what the world would be like when I was 50 (not there yet, but gaining). Most of them imagined extensive underwater cities (which is interesting considering my post the other day about the things that DID change). I wish I had some of those drawings from back then. We don't have any underwater cities yet, but maybe this man has created a "proof of concept."
