yes yes the simple sample above taken horizontally gives ideas eh? great to hear more interest in it. i like the thought to split water, planty power there but forexanple H2 peroxide got planty power also and is used allready, but sunk the kursk -its dangerous!- however producing and using on site reduces the risk and gets away with transport and storage laws i think. a lot to talk we have. when back later today i'll place some more links and some better ideas on making such a layout (and prototype?)

some interesting plans but auction ended

There are designs and later on made models of a keel-propulsion; i.e. a hydraulic unit that is placed in the bulb of the keel.

It never took off - for some reason.
