Funny thing is, that she would probably do 42 kts with 50,000 HP and the next 2 knots would take 3 times as much. Such is the rule of displacement vessels. To take that one theoretical step further, if they wanted to go 46 knots, they's need 400,000 HP. 47kt 1 million. 50 kts a bezllion HP |

As the speed increases, the vessel begins to outrun its bow wave. It then has to ride over the bow wave or push through it. The faster the vessel, the bigger the bow wave. Sort of like the increase in mass with velocity and, as the velocity approaches the speed of light, the mass becomes infinite. Only not exactly. |

The maximum speed of a displacement vessel is determined by its length. The longer, the faster.... with the same power. |

Your physicist buddy is playing word games. The torpedo is going so fast that flow detaches from its surface at the transition from the nose cone to the body. But it is most assuredly travelling in water. In any case the British seem to be laboring under the misconception that their Spearfish torpedo can exceed 60 knots. Perhaps he should call them and inform them of their error. |

I've been doing a lot of re-design and it appears that I can boost both the efficiency and the oscillation rate to the limits of mechanical check valves. With a platform like the Hoby, I think I can mount a tracking solar concentrator and have 3-4 kW of input power to work with and (perhaps) 50% of that in pump power. My problem is that I'm not sure that'd be enough to pull a twin-hull platform. Heh - it just occurred to me that if I needed a horn, I could disconnect the pump and use the engine (at say, } to warn off the jet skiers. :) -- Morris Dovey DeSoto Solar DeSoto, Iowa USA http://www.iedu.com/DeSoto/ |

Not gonna move a Hobie _fast_ but it will move it at a useful speed assuming you don't lose much efficiency in the propulsor. |

Thanks, John, that's what I needed to know. I'm not sure how well it's going to work out, but that tells me that it's worth a try. The engine isn't anywhere near as big a deal as the tracking system needed to keep the collector pointed at the sun. Propulsion will be essentially a straight path with a tee connection to the engine between a pair of check valves. During the expansion half of the cycle water will be discharged rearward, and during the contraction half of the cycle water will be sucked in from the forward direction. I don't need to go fast - I just need to come _back_. :) -- Morris Dovey DeSoto Solar DeSoto, Iowa USA http://www.iedu.com/DeSoto/ |

I've stashed the link for when I have an engine ready for the job. First I need to get engine and tracking system worked out. The Hobie (spelling corrected) will be a rental boat, so whatever I come up with will be something I can assemble and set in place at the marina, then lift off/disassemble when I'm done.

That'll give you a theoretical roughly 2HP. Enough to move it around, but -not- with much speed. Think 'trolling motor'. OTOH, if you can fit one concentrator/fluidyne, maybe you can get 2-3 of 'em on board. Now, you're approaching the capabilities of a 5HP outboard. That should be enough to leave a wake -- at least a small one. grin My problem is that I'm not sure that'd be enough to pull a twin-hull platform. Heh - it just occurred to me that if I needed a horn, I could disconnect the pump and use the engine (at say, } to warn off the jet skiers. :) That hurts just to *think* about it. |
