Agreed. I just need to know about possible (clear and present) dangers. I don't want to go back to "smoking" my e-cigs.
We can figure out the rest by ourselves.
Just the facts, ma'am.

I'll admit I took that post the same way, I didn't realize you meant it in this way. That I absolutely agree with.
Exactly! And I guess that's where my thinking has been the last couple days. A 40w dna reo doesn't exactly make me jump for joy. It makes me think, "uhm, I dunno", but a 100 watt reo? Now I'll doing and foaming at the mouth...
It was not clear following the conversation that vapor was the topic according to you. I apologize. I misunderstood.
Though 100% vg certainly is vapable. It just doesn't wick well on many setups. I vaped vg and vg nic base strictly for a while. That's vg plus nic powder... theoretically thicker than pure vg. No flavor or additives.
Temp control would be great for clearos and cartos. However, I think it's extremely unlikely that the industry will adjust for it, simply because of cost, and also because there's no reason to.My bad, I said 'low power segment' but I meant low power starter devices. Cigalikes, eGo class, the sort of thing new inexperienced vapers buy first. IMO this is the biggest market for temperature limiting or control technology, both in units sold and in need and the DNA40 doesn't fit in there, LOL.
After that the low/medium power, more expensive mod market and then high power devices once there are high power boards for them.
Just my opinion of course
Starter devices are mass produced, without too much of a concern on quality. Clearo is dead on arrival? No big deal, the consumer will just pick up another one. Product keeps moving, money keeps coming in - they're basically disposable anyway.
Most are wired with thin gauge nichrome simply because that's what they started with, that's what they have in supply, and it's pretty cheap. Most rebuildables are using kanthal, which is arguably a better option, but I highly doubt starter devices are switching.
Sure, there would be a market for starter devices with temperature control, but that would require switching entirely to nickel 200, or offering two different versions of the same product. I don't see that happening. Secondly, starter devices would require a battery that can support low ohm coils. A 700 mah cigalike battery ain't gonna play nice with a 0.2 ohm coil.
Temperature control, based on the market and current technology, is probably not going to be very mainstream anytime soon. Gotta use nickel 200 wire, gotta have batteries that can support sub ohm, and gotta have a chip capable of sampling coil resistance several hundred times a second. The industry isn't going to jump on that just for a minute increase in sales.
BOOM!
Agree but (always a "but"), the noob sees the initial cost and says, "damn that's expensive!" It's not until later that we think about the cost versus smokes.
Sent while presently sitting on my .... watching mind numbing prattle on the TV. 257 Channels and nothing on.
Don't know about cartos, most carto users want cigalikes, and I can't see that chip going into a supermini or mini battery.
However, Kanger and Aspire are already working on nickel coils for their clearomizers. And Evolv is bringing a DNA 25 chip next.
Whether it will become a new industry standard remains to be seen.
Yup. Nicotine in its pure free-base form is a liquid, not a solid.

i did a little research on the hygroscopicity of of PG and VG.

Hygroscopicity
Glycols are hygroscopic. If placed in an atmosphere containing water vapor,
they will pick up and retain moisture. This property is responsible for the
many applications of glycols as humectants and dehydrating agents. In
many of these applications, glycol-water solutions are used. The addition
of water modifies the properties of glycol. The properties of both anhydrous
glycols and glycol-water solutions are presented in this publication.
The relative humectant value of glycols is influenced by humidity and
temperature variations. These variations for a range of temperatures and
humidities frequently encountered in humectant problems are shown in
Figure 3, which may be used to determine the amount of glycol needed to
condition a given quantity of a product requiring a humectant.

HYGROSCOPICITY, the ability to attract moisture from the air and hold it, is one of
the most valuable properties of glycerine. It is the basis for its use as a humectant
and as a conditioning agent in many applications where both the glycerine and the
water it holds act as plasticizers. The net effect is to give products the desired
softness, flexibility, creaminess, and shelf life.
On exposure to air, glycerine at a given concentration gains or loses moisture
until it reaches another concentration that is in equilibrium with the moisture
(relative humidity) in the surrounding atmosphere. The equilibrium concentration
is relatively independent of temperature change within normal atmospheric limits.
the humidity in saint paul today is 67 %.

Temperature is still a function of power. So if you have some max temperature setting, it's going to limit the power so it doesn't get too hot. I guess I don't quite get where your going with this.
Exactly. so the 250 watts will not be satisfied unless you can keep it under the temp limit. Which is what you want. When you tell me now go at 100 watts I imagine dry hits and glowing coils. But with temp control I know that I can get the 250 watts without dry hits if I can keep a stream of liquid without fear of dry hits. It is like giving an open ended power source. As long as you give it more liquid we'll give you more vapor.
Exactly. For example I've heard people talk about vg breaking down into acroline. Ok, but look at the process to do so in a lab. As far as I know, unless I'm wrong it must be done in a pressure vessel. Why? To raise the boiling point of the vg, otherwise it would just turn into vapor. It's not the juice or it's contents that would ever worry me in terms of "breaking down due to too much heat", now the solid matter. The "gunk" that forms on the coil. If that coil goes dry then it can certainly heat up enough to burn that stuff off. I mean, that's why we dry burn our coils in the first place. And what could be happening in there is wherei think any tell potential danger could lay.
I tried VV one time, just couldn't do it, so I switched to mech. Now, I love my mechs. They're simple, basic, affordable (clones are at least) and they can fit my style. But, lately I find myself eyeballing VW mods. The idea of getting that same, if not better, vape experience on a higher ohm build really intrigues me. The prices don't. Literally only reason why I haven't thrown down for a VW mod is that no local shop has an 18650 box mod for under $100, and I have a hard time justifying spending over $50 for anything vape related.
LOL
Why?
Did you not learn that vg is vapable?
I learned that nic is a liquid. Thanks Rossum.
If you learned anything that should be a net +2. If you didn't then check the diy section. It's a common suggestion to vape just pg and just vg to get an idea what you're working with.
