Man of the Century

This man won $41K in a contest called "Live Your Dream" and used it to construct an energy self-sufficient submersible, powered only by a stationary bicycle and solar panels. He lived underwater for 13 days, and for entertainment, "watched videos on his laptop and used a wireless Internet connection to communicate with schoolchildren from around the world."

What he proved is that some people dream of living in isolated cramped quarters watching videos and surfing the internet, and that this environment can be constructed cheaply almost anywhere, even under a lake, even with today's technology. This is the future. This century's technology will allow more serious ventures, including sustainable food supply and maintenance. And this century's scarcity will require it.
