More and more these days it seems we like to experience life in private, without annoying intrusions from our neighbors, our fellow countrymen or our mother-in-laws.

With the success of the Walkman, listening to music became a solitary experience. With the success of the VCR, moviegoers found they no longer had to suffer through a matinee with a throng of inconsiderate candy-wrapper-opening individuals.

Of course the cell phone has made public pay phones almost obsolete and the Internet is now making it possible for more and more people to work remotely, at home, in the comfort of their private offices.

So what's next? Well, how about a personal, one-seat submarine? I kid you not. According to the good folk over at Engadget, "A Dutch company called U-Boat Worx is finally ready to release its battery-powered C-Quester 1 to aquatic enthusiasts worldwide, which will allow them to cruise down to depths of 50 meters at a maximum speed of 3 knots for up to two-and-a-half hours."
