To reduce the threat of a house fire, I propose roof pools. Combined with those ceiling sprinkler devices, your house is safe from fire.
Added bonus: This will be lots of fun in the summer. "Hey! No running on the roof."

Yeeeesss... but (amazingly enough), water weighs about 1 tonne per cubic metre ..... are you looking to retrofit this to existing structures ? |
|
| |
(Yes, I know, a tonne is a unit of mass, the density of water varies with temeprature, OK, OK). |
|
| |
As seen in "The Towering Inferno". |
|
| |
In an earthquake it could automatically douse the potential ensuing fire. |
|
| |
//your house is safe from fire//
Apart from electrical fires caused by the roof pool leaking onto the wiring in the attic. |
|
| |
Some large buildings have large water tanks mounted on hydraulic rams part way up the structure to dynamically damp oscillations from wind forces. The Sears Tower in Chicago may be one of these. |
|
| |
That's less fun. Who wants to swim in a tank in the Sears Tower? |
|
| |

|
| |
That's what I'm thinking of, 8th, water tanks on the top floor. They explode in "The Towering Inferno". |
|
| |
There's another movie I've seen recently that has a roof pool collapse inward and wash the bad guys out of the penthouse apartment, but I can't remember what it was. |
|
| |

// water tanks on the top floor // |
|
| |
In The Towering Inferno they were the building's water supply tanks. The ones used as inertial mass for active damping are positioned one half to two thirds of the way up the structure, often at an oscillatory nodal point. |
|
| |
The ones I've seen, read about, the damping load is very near the top and usually big air-conditioning units hanging on a pendulum thingy. |
|
| |
Hmmm, maybe I'm confusing some of the stuff I've seen on earthquake mitigation with active wind damping. I suspect we're both partly right. |
|
| |
[angel]//roof pool leaking onto the wiring in the attic// I would hope you'd construct it in a way that wouldn't leak. Most comercial buildings have a fire sprinkler system, and I'm not aware of leakage being a problem. |
|
| |
I think its a cool idea, just don't be installing one on my roof. |
|
| |
my junior high had this, but i never got to go to it |
|
| |
[josh] Ok, no roof pool for you. And you can't play in mine either. |
|
| |
[dave] Really? For fire suppression? Which jr. high school did you attend? |
|
| |
What if the pool were filled with light water...like nuclear reactors. Probably not as refreshing.... |
|
| |
But useful if you have your own reactor. But there's problems there - sure you can put out a fire, but then you have to deal with a meltdown... |
|
| |
(realizing quite late that I never answered [8/7]'s original question) |
|
| |
I was thinking of new houses. Using concrete or steel in construction is fairly common these days. A steel frame would definately work, though I'm envisioning concrete columns holding up a mostly concrete pool with large circular plexiglass skylights. The shell and rest of the house would be of normal construction. (sigh) If only I had the time or artistic ability to draw this one out. |
|
| |
Generally, I like the concept -- although I agree it would not work in places prone to earthquake. (+) |
|
| |
How about a mini version of Roof Pool: Jaccuzzi in the Attic. Could be used to put out small fires. |
|
| |
I've seen houses with giant tanks of
water on top of them for this very
reason (in an area that experiences
frequent forest fires. they're not just
paranoid nuts). I like the pool part
though |
|
| |
Very cool. Where were they? I'd love to see the design. |
|
| |
Cool is the right word. A few inches of water on the roof would suffice to keep things a bit more livable in the southwest. And even with a little water, you could have a lot of fun. Running and sliding...."Matt, watch it, don't get too close...damn, he went over again." |
|
| |
Ok, now I have to post my idea about tinted roof water pools. It's less fun but more practical. |
|
| |
If you build your roof right (read: wrong) you'll get roof pools for sure! |
|
| |
To keep cool cheaper the idea is good. Go up top
and take a dip. Bring the body temp down. The roof
pool could save lots of money on AC. The roof pool
could be designed to drop down, 60-80 feet, starting
a flywheel going. A prairie wind mill could pump up
water. The wind mill would use the superstructure of
the roof pool flywheel puller, to gain solid height. |
|
| |
Almost followed you there [Steven]. Is the flywheel to generate energy? |
|
| |
Are any of those roof pools hooked up a fire sprinkler system? |
|
| |
I suppose the flywheel can take up the downward
force and translate it to either electricity or
compressed air. The Compressed air could power
your car or washing machine. A good pull on the
flywheel could give us an hours worth of juice,
perhaps. The water could grow algae, for the
oysters in the basement. Who doesn't love an
oyster stew? What's to criticize about oysters? |
|
| |
seriously though the oysters would be fed indirectly
from grey water and urine, or as I call it gra-pee.
This saves energy in pumping excess water and
waste off-site, instead converting it to height, which
translates itself into food, and electricity. The
photosynthesis for the algae conversion would take
place not just in the pool, but in arrays of cascades
or closed glass tanks. |

//What if the pool were filled with light water...like nuclear reactors. Probably not as refreshing....// |
|
| |
Light water is Perfectly Ordinary Water; that is, Water that is Not Heavy Water. The term is only used in the context of nuclear reactors to avoid ambiguity. (Light water can also imply deuterium-depleted water, but usually it doesn't). |
