It turns out the stuff is supposed to be used as a fire suppressant that won't get stuff wet (good for museums) and won't degrade the environment like other dry fire suppressants.

It also means that it can be used on fires where water ordinarily couldn't be used - eg it won't short out electrical equipment, so you can use it instead of CO2 extinguishers.

I also like the idea of using it as a coolant. Water has a far higher specific heat capacity than air, making it a far more efficient cooling medium, even before you consider the extra capacity you gain from the latent heat absorbed when it changes state. You really could use it to cool computer chips very efficiently - although it would mean you'd have to add heat exchangers inside your case: the beauty of air-cooling is that it can be open-system and you just use atmospheric air, but you'd need a closed-system to use this "dry water" - unless you wanted to top up a storage tank every few mintues whenever your computer was on!! http://ubbxforums.ubi.com/images/smiley/16x16_smiley-very-happy.gif

EDIT: It's just occured to me though, that putting a heat exchanger in wouldn't be quite the disaster I was thinking of. If you calculated your coolant volumes to make sure that the "dry water" evaporated (ie didn't put too much water in the system), you could have a condenser as part of your heat exchanger, and run the dry water through a turbine. Meaning you could recover some electrical power and reduce your utility bills! Plus think how awesome it'd be to have a computer that had a jet turbine in it!! http://ubbxforums.ubi.com/images/smiley/16x16_smiley-tongue.gif

This is very very confusing. Why would you want dry water? Who would want to make dry water? How can dry water exist? and most importantly, Why would it be awesome to have a computer with a jet turbine in it?

Did you do it all by yourself?

How long to think it up? As long as it took me type it - it just flowed off the top of my head. It wasn't pre-planned or anything like that.

Yes, I did it all by myself. And it's not particularly smart, really. Outside the scope of general knowledge for most guys in the street maybe, but certainly nothing spectacular - I'm an engineer, and that sort of thing is basic bread-and-butter stuff to us. We spend years at university learning about it all, so you'd have to hope it wasn't a total waste of time, right?!? http://ubbxforums.ubi.com/images/smiley/16x16_smiley-wink.gif

And "smart little Gavy wavy"?? Was that supposed to be sarcastic or patronising? You should've said - I'd have written a toned-down layman's version specially for you with all the big words removed (that means "taken out")... http://ubbxforums.ubi.com/images/smiley/16x16_smiley-tongue.gif

That was mean in a funny kind of way http://ubbxforums.ubi.com/images/smiley/blink.gif

Jet turbines in jet engines are extremely useful, some might say necessary!

Come to think of it... a laptop with one 'o them would be kinda cool...

Sorry to bore you with a technical note, Prince, but you'll just have endure this one... http://ubbxforums.ubi.com/images/smiley/16x16_smiley-tongue.gif

Turbines are indeed useful in most "jet" (ie, gas turbine) engines, but not actually a necessity: you know how a ramjet works? There's no turbines in them coz there's no compressor to drive.

Unfortunately, you really need another engine to get them supersonic before they'll work at any real efficiency, coz you need to get sonic shockwaves to form so that they compress the air on the way into the engine. (The more you can compress the air before you burn it, the better - which is why diesel cars are more fuel efficient than petrol ones - compression ratios for diesel and petrol engines are around 18:1 and 11:1, respectively.)

Ok then, what happens if I have a bucket... and I fill half the bucket with dry water, and half the bucket with wet water...

Stir...

And then pour on my driveway. How long would it take to dry in the sun?

Half as long as it would if the bucket were filled completely with "wet" water, obviously! You always have to think of things in too much depth! Engineers have to maintain as simple a view as possible of things...

The great Albert Einstein himself once said "everything should be made as simple as possible - but no simpler".

It wouldn't dry out the wet stuff, no. How can water ever dry out water? Fool! http://ubbxforums.ubi.com/images/smiley/16x16_smiley-tongue.gif

What it would do is to dilute the water... http://ubbxforums.ubi.com/images/smiley/16x16_smiley-wink.gif

I've seen on Mythbusters (Discovery Channel) that "normal" water in the microwave will boil... but distilled water in the microwave will not boil!! Something to do with the impurities not being in the distilled water, therefore no air bubbles can be created, or something, and anyways, it won't boil.

So, then, if you break the surface of the distilled water (when it's removed from the microwave) with any object (spoon, teabag, sugar, anything) it will "explode" out of the coffee cup!! "Regular" water wouldn't do that, but distilled water would!!

What would dry water do?

Glad to be entertaining, Prince... If you want to "impress" people (in my experience, they're normally bored rigid rather than impressed) with your lecture on ramjets, maybe you ought to learn a little more about them here (http://www.grc.nasa.gov/WWW/K-12/airplane/ramjet.html)

Incidently (to improve your spiel), although ramjets are rarely used in practise due to no thrust when stationary (so you can't ever start the vehicle moving without a second engine), I believe your Tomahawk cruise missiles use them as their main propulsion system (a short-burn rocket to launch the missile initially, then a ramjet for the main part of the flight)...

And if you want another example of a turbine-free "jet" engine, there's always a pulse jet (http://www.airtoi.com/pulse.htm)...

It's kind of an early type of ramjet, very simple, but differs from every other gas turbine ("jet") engine in that it doesn't have a continuous mass-flow of air through it (in that respect it's more like a single-cylinder internal combustion (think road cars) engine. The most famous use of pulse jets was in the V-1 "flying bombs" that the Germans used in WW2. http://ubbxforums.ubi.com/images/smiley/16x16_smiley-wink.gif
