A dolphin like -probably nuclear powered- submarine, with an inner "skeleton" where people can stay. Includes a thick insulated area. Driven by tail and steered by nose. Can jump above water too.

Given the pressing need for a submarine is to stay watertight at great depth, making it flexible would probably be more than our current technology can manage. But I have seen some interesting prototypes of fish and/or dolphin style swimming robots. |

// The idea of jumping a submarine out of water is interesting. Just how do we achieve that? // |

Make the hull out of Francium, mayhap ? |

You'd definitely have to address the issue of the frictiveness of the hull. =/ |

For jumping out of water, I suggest as a preliminary strategy that one could adopt the "The wizard of Oz" school of thought and, much like the monkeys with wings idea, you could attach either a large number of fish to the stern (synchronised electrical impulses) or better still, the back-end of a whale. Really, the only problem with this is the method of attachment and keeping it all watertight. |

I read an article about Binladen trying to purchase one man submarines from some manufacturer in the States. If memory serves, (jury’s out on that one), these subs do indeed jump out of the water. |

Hey memory does serve... [link]. |

Now <b>Halfbakers PLEASE NOTICE</b> |

First you belittled the idea on the grounds of impossibility: no existing technology for the friction, for keeping it water tight etc.
This, while phoenix already put up a list of links, showing it could be done technically (with robots). |
|
| |
Then we find out its baked!
If you are serious, and want to believe this is a constructive site and not just one for ranting at, it would be nice to hear your appolgies. |

"Wiz Oz schooling"
The idea of flexibility made me think of the skin of this sub being tile-like with some flexible and some hard plates therefore somehow affecting the surface pressure of outside water - no sorry, logic still cooking . |

You fellows need to do your research before rambling.
First I'll address flexibility issue. The problem has been contemplated and it is envisioned that a simple fix would be to use a solid hull for the payload (or human cargo), and simple attach a non water-tight outer skin and tail.
Tombomb: The wake of a fish motion device is virtually still, as the opposing vortices created by the tail cancel each other out. This is why fish tail (Thunniform) motion is so much more efficient then propeller propulsion.
Pharaoh Mobius: I don't believe frictiveness is a word, further I don't see the relevance of friction to the problem of having a sub jump out of water. I don't know why you would want to jump your sub out of the water, but if you did, as long as the passengers were well braced, I don't see a problem.
To conclude: Thunniform Prop Subs (fish motion subs) are very real, and much further along technilogically than you may think. You shouldn't knock the dreamers, because if it weren't for them you wouldn't have anything to type your ignorant messages on. |

The flexible sub is a great idea I am an inventor working on a flexing sub theory right now and the technology is here now so why not right and nanotechnology is right around the corner and my idea has a great chance of implementation in the military R&D for the USSOCOM..well it's starts with 1 idea and then every thing flows into motion so let's get the motion in the ocean.. |
