If the wick is dry, you can freeze the coil, and the wick will still be dry. Shut down all voltage, and the wick is still dry. I don't see how reducing the voltage (or the temperature) makes the wick suddenly wick faster.
It doesn't. It makes the coil less efficient at vaporising liquid, so what there is goes further.

I'll admit that I read the first 40 posts and skipped on to the 5th page here before posting.

I've talked about temperature controlled vaping devices for a couple of years now and expect that to be the future of vaping as long as the cost is in line. After all, what we are trying to achieve is the right atomization point for our juice. We express that in watts, volts, and the efficiency of the design.

The trouble the concept is that you'd have to have a thermistor in the atomizer coil that's embedded in the wicking. That also means another set of wires from the control board to the atomizer. The thermistor needs a constant voltage to produce a consistent reading. It's expensive and needs two more pins to work, meaning a 4 pin connector to the atty. The good part is that you could set the temperature you want and let the mod maintain the vape. The down side is that like any coil it will begin to lose efficiency over time as the coil crusts over and require a higher temperature setting to maintain flavor and vapor (just like a voltage or wattage controlled mod).

Thermistors can be tiny.

It's easier if you don't try to jump straight to perfection.
Just finding a useable improvement would be a step in the right direction.

the outcome is consistent vapor production not vapor temperature. Coil temperature in relation to the liquids vaporization curve produces the most linear control over vaping possible. Vapor temperature while i guess might be important to some.. doesn't really matter to me at all and i suspect most other people.

For what it's worth, it doesn't matter to me either -
unless it starts to get to warm or hot; for me that's entering the danger zone anytime the coil is so hot that the vapor comes out hot.

I think the vapor temperature control will be a gadget selling point for the latest design. What we will end up doing is the same thing we always have, crank it up or down to suit our tastes.

The Drexel report is the best document I know of right now for measurements of the chemicals in our vape. Most of the problem with dangerous chemicals in our vapor is the voltage we decide to use. High voltage = high temps = production of acrolein and formaldehyde, among others.

http://publichealth.drexel.edu/~/media/files/publichealth/ms08.pdf

If you vape an occassional puff once every 5 minutes, your temperature controlled device will end up firing more power at the start of each vape in order to jump to a high enough temperature.

If you are chain vaping, your temperature controlled device will end up firing at a lower power because the device is already pretty warm to begin with.

Another limiting factor for high temps in the coil is the ability of the wick to absorb and deliver juice to the coil. A wet wick is a heat sink in itself. As long as the wick can continue to maintain saturation, the less likely it will be that the coil and the juice can attain the 500 degree or so temps needed to produce the bad chemicals. All that I've heard tells me that you will know when acrolein hits your taste buds.

We all know what burned juice smells and tastes like and avoid it like the plague. I can't imagine anyone actually vaping close to the danger point on purpose. We all like flavorful, rich vapor.

Which is one reason why it would be nice if your device slowed down the power the closer your coil got to such high temperatures.

What I would like to know is what the designers of these systems thought when they came up with the idea. What do they seek to accomplish that is not already available? I can't say that our little brainstorming session in this thread has shed any light on any real potential breakthroughs. Best so far is probably "eliminating dry hits". Other than that, what can it accomplish that VV can't?

Ultimately it is about a good atty design. Stick as much sensors and electronics in an atty you want. If it's a bad atty, it's a bad atty. That's the Achilles heel.

It won't; you just don't burn your juice.

I agree.

If you're running vw and your wick gets dry you get burnt hit.
If you're running temperature, you wick wont go dry, because the mod isn't going to let the coil get hotter.

And that's what I orginally responded to.

And you shouldn't be driving a car. For one thing, it puts out emissions that mess up your clean air. For another, a *lot* more people die in auto accidents than you can show have suffered harm from vaping.

You just hate vaping, and are holding vaping to a "must be 100% safe under all circumstances" standard that nothing in the world can match.

Wow, that escalated quickly.
so i hate vaping?!? LOL what a freaking joke.

we put on our seat belt when we get in the car, because it increases the odds of surviving a crash.
automotive manufacturers have done a lot of R&D to make cars safer. i see no reason why e-cig manufacturers would not do the same.
and to suggest that we do not seek to improve the safety as well as the functionality of the e-cigarette is just backwards thinking.

You're saying things like "you shouldn't be inhaling it at all.", and "the only thing you should be inhaling is clean fresh air".

Yes, it sounds like you hate vaping, else you wouldn't be here trying to spread unsubstantiated fear.

and to suggest that we do not seek to improve the safety as well as the functionality of the e-cigarette is just backwards thinking.

Nice try, but I never suggested that we should avoid improvements. If you're going to scream about how it's unsafe for us to inhale anything, I'm going to call you on it.

i can not find one single doctor or lab report or study, that would even suggest that "vaping" is a healthy thing for your body...
but most would agree that vaping is a healthier activity than smoking tobacco.

any amount of 3-ethyltoluene is not going to be a healthy or safe thing to inhale..
3-ethyltoluene is found in both analog cigarette smoke and e-cig vapor.

vaping has some amount of risk to it, but less risk than smoking tobacco...

thats why vaping is called a "reduced harm alternative"
vaping is NOT a "zero or no harm alternative"... vaping has some risks.

Got no dog in this hunt happydave, but sometimes you can come across as "doom and gloom".

i am very aware. my username is kind of sarcastic.
im just a realistic individual... i do not bury my head in the sand. nor do i sugarcoat anything.

when you smoked, did you like to hear about how bad smoking was? of course not...


our current understanding of ecigs that is they are better for you, than analogs. and a lot of people hear that and think that vaping perfectly fine and will not hurt you. and that is just not the case.

pretty sure its with in our power to reduce the risks of e-cigarette use even further.
as time goes on, our understanding of the situation and technology will continue to improve.
to not utilize this for our benefit is absurd.

For anyone who think's e-cigs are totally safe:
this is a list of "voluntary reports of adverse events involving e-cigarettes from consumers, health professionals and concerned members of the public"
sure some of these reports are fraudulent. but some of them are not so easy to dismiss as fake.
hopefully as time goes on, we can improve our understanding and design of the e-cigarette to reduce the number of adverse consequences.

I understand what you are saying, but there just aren't any studies out there that show vaping to be anywhere close as harmful as cigarettes. We all used to smoke right? Compare vaping to that, not right to compare it to breathing air, that's just not realistic.
