What I was referring to, was the destabilizing effect of all that water in high areas .... loss of stability due to high weight, coupled with loss of stability due to "free surface effect". There are two types of stabilizers, employed on ships .... active ( gyro controlled fins), and passive ( such as FLUME - doubt QM2 is using Flume). The flume system uses water in thwartship tanks (preferably up high) to counter rolling .... basically a moving weight, or, another way to look at it, turning free surface into an advantage. I don't know of any ships which store water to use in a gravity feed to supply fire mains. The power used with fins, in no way affects the power available to the mains, to drive the ship .... their adverse affect will be drag related. Their serendipitous, synergystic effect, hardly adverse. Stabiliser fins are flipper propulsors, too, if programmed right. Terry Spragg wrote: otnmbrd wrote: That could be a good thing ...... all that water, all that high up ..... Just think, anti roll weights up high, water stored for fire fighting by gravity feed. Stabilisers use some power to stop rolling, imagine instead the power used to move high counterweights to stop rolling? The power used in the anti roll stabilisers control the scavanging of energy from the forward motion of the ship to stabilise the hull. How much power is actually required to stabilize the liner, counting the loss to forward propulsion? Are the stabs programmed to recover propulsive energy in advantageous postures? Does the concept also work for skyscrapers, to charge gravity powered fire sprinklers while stopping earthquake and wind induced motion? Sloppy water couplings and hydroplaning bearings would leak water recycled for evaporative air conditioning, replacing the action of trees lost to the ground site, while allowing some form of 'natural' waterfall for gardens aloft in the skyscraper, capable of doubling as waterslide escape routes. Add a few mountain goats, climbing walls and mountain flora, and you have got an environment for a large dwelling complex housing workers and industry whilst reducing commuting impacts, even saving wage requirements.

Can I get that in shareware? Rick Shure thing, dude. You do the engineering study calculation of losses and gains, etc, where we show that programming the flippers to recycle roll energy, saving fuel for propulsion is financially beneficial, and write a letter to convince the owners to pay me to rewrite the software controlling the fins, and I will give you half of the proceeds. Is that shareware enough for you? Saving even one percent of the fuel used on the QEII is a lot of money. Of course, if they come back and say that that concept was their intellectual property from 20 years ago, and sue you for exposing trade secrets, you are on your own. -- Terry K - My email address is MY PROPERTY, and is protected by copyright legislation.

... [Spraggonics snipped] ... Terry, good to hear from you again. Hope the new year finds you well. BTW, I'm sure you'll agree it's a big relief that reading _all_ the messages here is not compulsory. -- Good luck and good sailing. s/v Kerry Deare of Barnegat http://kerrydeare.tripod.com |

Of course, if they come back and say that that concept was their intellectual property from 20 years ago, and sue you for exposing trade secrets, you are on your own. What? The trade secret to some kind of perpetual motion machine? Think about it for a second ... "scavenging" energy from the forward motion is called slowing the ship down to get some of the power back that you put into it to speed it up to begin with. Why don't you just give me the money instead. Rick |

Rick He's talking about bartering some roll momentum into forward momentum. He may come on weird at times, but I think he may have a (small) point on this one. Brian W |

That's not to say it would be a net saving of energy, but the anti-roll fins already do their thing at the cost of added drag. "Programming" them to net forward thrust might not be possible except at low speeds, and increased roll (although they would still dampen it), but it would work. Regards Doug King |
