Personal Submarine for 845k
joeldg writes "CNN is carrying a story on the gemini three-person submersible.
'Forget the yacht, mansion and private jet. This is Gemini, the family submarine described by inventor Robert Leeds as the world's first underwater sports car.' However, the submarine only goes about five knots, so speed is not its primary focus. It can handle three people for three days at depths of up to 50 meters. Not quite a James Bond sub-car, but cool nonetheless. The official site has lots of pictures."
I was a sonar operator in the navy.
Radar, of course, doesn't work underwater, as you probably know. Sonar does, but it's really difficult to pick up a craft this small on active sonar (Not enough "surface" to give a good echo). You *could* maybe detect it passively, but I suspect this sub is very quiet, being electrical and all.
