This might not work, as I've not had an opportunity to test it, having only just thought it up.
Tall buildings in a dense city present fire management problems regarding accessing the specific floor that a fire breaks out on, what with the height and the cramped and mostly obtuse layout of streets,
etc.
As well as attempting to directly apply firefighting measures by snorkel vehicles, it might be worthwhile to throw relatively huge globs of water directy at the target from a suitable distance, thanks to a high-precision high-tech trebuchet.
This would require a wirelessly accessible database of almost every facet of every building in the city, and calculated points of location that are easy to get the water treb vehicle to, in order to fling water at the building from. The treb vehicle would allow precise delivery of water, foam or any other matter that puts out fires, according to what stage the fire is at.
It might be tempting to think that the more water the better, but if you're effectively throwing an entire swimming-pool's worth of water in one fling, this might cause more physical damage than you'd want. The payload would have to be calculated to be optimum without risk of damage to either the structure, people trapped inside, or people in lower floors below or on the ground.
This wouldn't replace the existing fire appliances, mind you - it would simply be in addition to.
* When I say 'water' I generally include all other materials used for fire quenching.
What happens to a glob of water

Sounds like it took inspiration here. [Canuck, Dec 05 2006]

What's to stop the water from becoming less of a 'glob' and more of a broken mass of water? |
|
| |
I don't know if the water would remain constant enough to fly long distances... |
|
| |
Finally, water is fairly heavy, so the whole damage to property or people is a fairly big concern... |

There is currently a firefighting concept being experimented with, that uses launchers on the truck, kinda like rocket launchers or artillery fired at very low velocity. The projectile is a canister containing a dry chemical extinguishing agent, and the "gunner" sights in on the window and fires the projectile through it, once inside the projectile 'explodes', dousing the room in extinguisher. Several projectiles may be used if one doesn't do the job. |

This would be something to see on an oil fire. |

It would need to be encased in some temporary, breakable flexible enclosure I would imagine. Perhaps something made of latex ... Colour code the enclosures to indicate their contents. The enclosures could then be stored in stacks on the fire truck and hoisted into the trebuchet by crane. |

Would make watching news coverage of fires more interesting. Can anyone remember the terrible News 24 BBC footage of the Bunsfield Oil Depot? 24 hours a day, still burning. |

laminar flow(like in Las Vegas shows) of h20 to a difraction grate(apparatus)
on site that forms an ultrafine mist that is the best way to remove heat quickly |

Bunsfield? It wasn't me, I was, er, visiting my mother, yes... |

Come here Beaker, and hold these two wires. |

Mount the trebuchet on the roof of an adjacent building so the momentum of the water will be lower. Wait a minute, somebody might create another idea based on something like that... too late! Thanks [twitch]. |
