Thank you for your efforts, Dr. Farsalinos!

We are all forever in your debt.

I really hope more vapers will contribute to your studies.

BTW, it was my understanding that commercial nickel coils will be available soon--and that one can vape at low wattages with the dna 40 which offers step-down capability (down to 1 watt ;)).

Dimitris is a good man. Thank you again, Dr. Farsalinos.

And since I have you here--did you have a chance to look at Aspire's new BVD coils? They are wrapped in something Aspire calls ceramic biomesh. My concern is that that material tends to crumble and disintegrate when dry, as demonstrated by one reviewer who actually took a BVD coil apart. These coils are widely popular, are the users at any risk of inhaling ceramic dust into their lungs????

My sentiments exactly.

I watched Rip's video and decided I don't want that kind of filler in my tank. That material obviously deteriorates and crumbles and Aspire is aware of this--why would they install a mesh screen otherwise? And that screen is not going to catch those minuscule glass particles. I have no desire to inhale them--or to choke on them. :D

That's just my opinion--others may disagree. I prefer the old filler (similar to the filler in Kanger's duals).

Go to 12:50 into the video:



Sorry retird--I didn't mean to hijack the thread--but it's not every day that I get to talk to Dr. F. :blush:

Thanks for all the new links retird!:toast: I can't suck this information up fast enough, or get enough! :)

The term "Game changer" is bandied about in many fields, but it's rare to find something that actually is. In the case of the Evolv DNA 40, it really is a game changer.

Thank you Dr. Farsalinos for all the time and effort you put in to make vaping as safe as possible for everyone.

With the advent of temperature control, that universally ignored component of watts will be realized: watts are joules PER SECOND. That is a dimension hardly anyone takes into account when talking about wattage ... an unregulated build has a rising heat curve that will limit total draw length. With real time temperature regulation, you can take indefinite pulls. The total energy transferred could well be the same or higher.

I think once someone approaches from that angle we will see improved results even from the vapor volume standpoint.

For the wires, we have the lab and equipment to perform tests on wires. Unfortunately, we do not have any funding. The idea and protocol of testing wires is ready since last year. But we cannot proceed. It is a pity, because we could easily find the most appropriate wire, which could be used even in large scale production without any problems and without elevating the cost of the products. It seems that we will not even reach our target for the current crowdfunding, because the response and participation-contribution from the e-cigarette industry is until now disappointing.

We expect the professionals to contribute, not the vapers. In every industry ever, it is not the responsibility of the consumer to support research...
Yet ultimately, we consumers are the ones who will benefit most from the knowledge your research will bring. So please don't discourage those of us who can afford to help fund that research from doing so, even if we are "just" consumers.

I believe this is the study you are trying to fund?

The problem with the DNA device is that the nickel wire has a very low resistance, thus, i will not be able to compare the results with low-wattage vaping (e.g. ego batteries or anything below 10 watts). My purpose was to compare the temperatures and emissions of temperature-regulating devices vs conventional devices.
My understanding is that the DNA40 is capable of acting as a conventional device, even with a nickel coil, you just have to turn temperature control off. With a 0.2 ohm coil, you should be able to get down to 5 watts (and probably lower, once the coil warms up a bit). Unfortunately, I don't have a DNA40 in my hands yet either. Perhaps some of the folks here who do can confirm?

Have you seen the crowdfunding text?? I SPECIFICALLY mention puff duration as a major determinant of toxins (probably). Wattage x puff duration = Joules, as you have mentioned.
That is why it is EXTREMELY important to realize that higher wattage means less puff duration in realistic use.

If the DNA has the capability to use low wattage with the nickel wire, we will definitely test it.
The real temperature measurement experiments will start next week. We will probably be able to measure temps every fraction of a second....

This is specifically in regard to higher-end vaping performance. I know that research tends to focus on lower-end consumer behavior; that's not what I'm on about here.

That is why it is EXTREMELY important to realize that higher wattage means less puff duration in realistic use.

That's way too unreliable of a statement to make. Cloud chasers are after max wattage and they take longer drags than anyone. Amount of liquid processed may also be a relevant measure.

If you have a single instance of overheating that burns a wick or vaporizes metal, the total energy could well be far less than a long, well-regulated draw, yet far more toxins will likely be produced.

I like 6-7 watts per coil... :facepalm: :blush:

Come sit next to me, Katyaaa. Welp, sit one chair away. I'm at 8-9w. ;)


Oh, we did. Over and over again. :D


Shhhhh! No one is supposed to know this!


Hmmm... I'm trying to think... who might have some old Darwins lying around his house... Lemme think... :D :lol:

Sorry. Just couldn't help myself. :p :facepalm:

Ummm...... thinking..... who could that B? ;)


<forgive the momentary diversion please> :)

Oh funny, funny... Just you wait. Just wait till I get my paws on that DNA 25 that Brandon promised us. I have big plans. I might even go as high as 12 watts. You watch me, girl. :evil:

Shhhhh! No one is supposed to know this!

Now she tells me... :facepalm:

Ummm...... thinking..... who could that B? ;)

This is the biggest game changer yet when it comes to e-cigs.

I've ordered an rDNA 40 from Vaporshark, as I like the small size.

Yeah, this is pretty big. It may change the way we vape--just like variable voltage did a few years ago. And fillerless toppers. And the RBAs.

Pretty exciting, isn't it? :)

Cloud chasers are direct lung inhalers. This is a completely different story and needs separate experiments. These people are inhaling a large volume of air per puff. That is completely different pattern and it cannot be compared with regular vaping.

You think lung inhaling is different from what "normal" vapers do?

What is "regular vaping"?
