"Superfine Misting Nozzles are excellent misters for summer cooling! The mist put out by these nozzles is almost like smoke, so fine that the spray hardly reaches the ground."
Might do the trick?

Looks close, but it would take WAY to much PSI to get the pressure right for our uses....
I think we might be on the right track though...
edit: after looking at your mister you found above it looks like it would be close the mister I found at the bottom... dunno which would work better, so sounds like we need a MIST OFF! (just kiddin =P)

OK, Check this out!
Fog Nozzles and other system components
Scroll to the bottom of the list in the Brass (or Stainless Steel) fog nozzles.
The one at the bottom is a hosebarb nozzle that takes 1/8 OD tubing, and is rated for 45 PSI+
Now, I did a google search for a Bar to PSI conversion, and the pump I listed in the first of the thread ( cmp17l ) is rated at 3 bar, or approx 44 PSI
Basically, you would only need a sealed bottle with a tube coming out going to the Pump, then the pump to the Fog Nozzle... and the pump operates at 3VOLTS!!!
I dont know how much it would cost for one of those pumps, but I am seriously considering this!
You would have to order at least 3 Fog Nozzles off that website to get over the $10 minimum order, I cant see the pump costing more than $20...
Gentlemen(and Ladies
), if this works, we have found a way to do away without the atomizer all together...
We would need to find a way to heat the mist so it feels the same as a normal atomizer, but we can do that later if we can get something like this to work!

Well, my original idea was a 2 switch deal, 1 push button switch to deliver a shot of juice to the wick of the atomizer, and the other switch to light up the atomizer as usual.

I think normal e-vapour is already mostly a mist of micro-droplets,
I guess that's why it looks like smoke.
It's just a question of the size of the droplets.
Personally I'd much rather inhale a mist from e.g. a piezo atomizer
or high pressure aperture device, than from a heated coil.

freddo - the vapor is mostly already a mist by the time we inhale it; at least the VG / PG component. The water, alcohol, flavorings and nicotine will have partially condensed also. The droplets in the recondensed mist will be warmer; otherwise there's not a big difference.
Exogenesis - yes, the droplet size of the recondensed vapor might be smaller.

Cold mist
Pros: longer battery life
Cons: mist will feel cool
The juice could be heated before being misted.

i see, thanks alot guys. I think i might have to have a go at building one of these things! Do you think temprature would have any effect on throat hit?
We keep coming back to trying to find the simplest,least technological (therefore most reliable) way of introducing either a liquid, or better still an atomized mist to a "warming" element.I have mentioned this in another post but the idea will not leave me.Say the juice (maybe 10ml) was contained in a pressurised cartridge, allong the lines of a gas cigarette lighter or soda stream cartridge.Such a unit would dipense a variable (at the hands of the user-think flame level of cigarette lighter) level of allready atomised juice directly onto a "warming coil" (no need therefore to materially alter current design).The release of atomised fluid could be controled, together with coil warming by either a manual or electromechanical switch and the volume of fluid controled with a simple manual restricter (cig lighter)
I am in the very early stages of trying to put together a working model based on a refilable cigarette lighter but am having trouble with finding a suitable propellant.Unfortunatly air duster canned air,my first and obvious choice turns out to be far from compressed air and therefore unusable.The search goes on!

I think one more pro that we haven't touched on is that it would make VG-based liquids entirely safe. With no heat, there's no risk of degrading glycerine to acrolein.
Not that I'm too worried - I think we'd be able to taste acrolein if any was being formed anyway, because it's so horribly pungent. But it would be a reassurance to those who do worry about such things.
propellants are always going to be tricky in a system designed for direct inhalation (the efficient ones aren't very lung-friendly - and my air duster lists "10% of the contents by mass are flammable" Whatever it is, I don't want it in my lungs!) which is why I think some sort of pump action might be better (whether pumped up prior to use, and then dispensed under pressure, or pumped for each puff.) How about something like this: Rexam PLC : Plastic Packaging : Dispensing Systems : Latest product launches : Sof'Cell fragrance sampler ?
According to the datasheet, it dispenses 50 microlitres/puff (that's 20 puffs/ml) and holds 1ml (about the same as a gamucci cart.) Assuming it's refillable, it would just be a matter of getting a sufficiently fine nozzle to form a decent mist. And it looks small enough that you could fit a heating coil to warm the vapour up without making it too bulky.
Might need to use weak nicotine in the juice with a puff-dose of 1/20 ml, but the up-side would be a lot more flavour!
Tests have been done that show no evidence of acrolein up to a temperature of 300 degrees centigrade (see Intellicig ECOpure report) Any hotter and you vaporise your mouth!;-)
Alan.
Well, I have to take issue with that, since it is widely reported that (eg
"When glycerol is heated to 280 °C, it decomposes into acrolein" http://membership.acs.org/c/ccs/pubs/CLIPS/JCE20030025.pdf
Sure, 280 or even 300°C are hot - but it cools down once it's away from the coil. And it cools very quickly - that's why it condenses out into a nice, palatable vapour.
It's evidently heated to boiling point (or it wouldn't boil off as vapour,) and it evidently cools down before it reaches your mouth as a mist (or you'd burn yourself.) Measurements of the coil temp in our atomizers indicate that it gets up to near that temp.
Like I say, I don't worry about acrolein (I've smelt it before - I know there's none in my vape!) but people do worry. And, in all fairness, if you ran a real mother-fogger coil that heated it up enough to produce acrolein, the n-micron diameter droplets in the vapour would still have cooled down to a palatable temperature after being sucked through 3-4" of room-temperature hardware (you seriously can't bring yourself to be within a few inches of a soldering iron tip?)
Just one more pro point, and a passing observation FWIW.
and as a matter of interest, they don't claim there is no acrolein, just that "No clear peaks were recorded at all but inference of spectra suggests the presence of glycerol and nicotine". Well, of course those are present - but it doesn't rule out other components.
"the presence of possible acrolein structures... as of the time of writing... have not been identified." This is guarded language - not an "all clear". At no point do they state that acrolein is NOT present. Just that they can't identify any peaks corresponding to it (in a data field that they admit is not "clear".)
Like I say, I'm not concerned. Without the benefit of gas chromatography and detailed analysis, I can confidently state that there is no acrolein being produced in my minipipe, because it doesn't remotely taste of rotting bacon. But some people do worry.
