i am sorry to bring it back but what is the reference of the alloy you use? Is it recognized food grade? We put vapor inside us, it is important. is it the link you put?

i doubt that brass have super using condition to use as HE though. i should bring the fact that leadfree brass is difficult to machine.

the concept is huge, please let me in on the train by put off brass.

even though i bought the PN pro recently im still looking for more vapes, and this one looks like its great. but will there be a small size smell proof case for the vape and the tools. also what about the smell of the vape. when stored with material on the go, will it reek? how long will it smell for if turned off with materials inside and taking 2-3 pulls after shut off.

...Luckily even in this worst case scenario, this would only be problematic in a corrosive environment. Which a vaporizer is not.

Good that you bring corrosive environments to the table. I come from Colombia and used to live in barranquilla, a city where the temperatures go as high as 40c and the relative humidity reaches levels that surpass the 90%. We are talking about an environment so insanely humid, saline and hot that some car models are first modified and get some of their metal parts replaced by plastic before being placed into that market.
It may not be a problem for me now that I live in Germany, but a question still bugs me: on what kind of environments are you running your performance tests? Will the ZenPen be up to a trip to the Caribbean? You know, the best place in the world to be vaping after all (:
Just as a sidenote: I remember that one of my first MP3 players required ad many as 5 battery replacements because the weather would break them. Nothing lasts forever, but in such extreme conditions everything will break faster. How well the ZenPen stand against extreme conditions in general? Can you give us some insights about your stress testing methods? that would make me at least a bit more confident about my future favorite vape, granted that you are indeed building a very sturdy device, independent of the climate conditions.

And regarding that whole brass discussion: you would not have that problem with the titanium edition, right? What other advantages would the TI model have over its counterpart?

After listening to your soundcloud podcast im more than sold, you guess seem like a really cool team. Hope a life time warranty makes it to the finals, that would place you add the ultimate vape company right with your first product, not bad!

"medical-grade" is not an alloy reference i look for sorry, it is expressed in a very specific normative way which describe the component and the way you obteined the alloy.

My questions are founded on specific metallography knowledge.

The situation of numerous heating cycle brings stress and corrosion to this piece of material. It is not the same for a screw in a medical tool that you do not inhale the fumes while torching it (well normally world is vast, may be some people like that).

For the project, i suppose that heating brass requires less nrj than SS?

Sorry to bother I want to spread vaporization to the world but for health reason

They have answered the Brass question already . This vape won't hit 1600F so the heat will not cause it to leach . The brass is enclosed in ss or ti , not open to the elements .
Don't expose it to a corrosive environment and it shouldn't be a problem . I live in a humid salty place and marine brass seems to outlive ss for the most part . The bottle of drinking water for sale here contains more lead then you would get from eating a zenpen . :2c:

hahah yes thank you! I'm glad someone gets it! We wouldn't make something that I plan on using every day if it was harmful. Everyone on the Zenpen team is a huge granola head, making a healthy product is really important to us!

I also want to mention, if anyone is interested in spreading the word on Zenpen and making a little cheddar, send me an e-mail and you can become part of our representative program! Conrad@zenpenvapor.com

Has anyone seen the newest blog entry? Zenpen will go CONVECTION... Wow! I hope it works out! It could kill Ceras and XP's and many more in one shot! Tough choice though... :\
How is it a tough choice? Honest question, I'm not being condescending. If it works out well, it'll be a good contender for the $100 price range, especially considering the form factor of it.

It's a tough choice because its much harder to produce a decent hitting convection vape from a power consumption perspective especially. This makes it extremely challenging in portables which is why most portables use a combination of convection and conduction if they use convection as convection alone its difficult to harness enough power in a smaller form factor.

I'm afraid that's sort of an apples to oranges comparison there. My galaxy s3 draws about .3W while running, .4 if I turn on the camera, flashlight and make a call. The reason these phones are possible now is because the screens, wireless components and system-on-a-chip's have gotten so ridiculously power efficient.

Heating elements are not quite that power efficient, nor can they really be made to be. We need to put quite a few watts through it to be able to make the heating element get hot enough to heat a constant stream of room temperature air to vaping temperature. The Solo for example draws about 11 watts to heat up, and it isn't entirely convection. The only real convection portable I know of is the Viip III, and it consumes up to 65W while running.

What we really need is a revolution in battery technology. It's what's holding us back. Not just in vaporizers, but in mobile technology in general. Right now, lithium ion is the best solution we have. But there are all kinds of promising technologies that may let give us more powerful batteries, and when they do we will see all sorts of innovations in mobile devices

Right, that's exactly what I was thinking, that there would have to be an improvement in battery technology as thermodynamic breakthroughs are exceedingly rare these days. I agree that it was a terrible analogy, as miniaturization doesn't really apply here. I was more speaking of the inevitable march of progress in general; batteries have come a long way lately so there is hope!

I don't think anyone could have said it better. These next few years are sure to show some battery improvements and hopefully they're on a commercial level.

Most vapes are using the same battery technology, what gets overlooked is increasing efficiency by preventing heat loss. That's where better insulation comes in. There ARE breakthroughs happening in materials engineering these days...

I don't disagree with you, but I think the improvements can be made through good insulation and careful air-path engineering are still fairly small when you consider the characteristics of convection vaporization. It requires about 2BTU's of heat to bring a cubic inch of room temperature air to 350 degrees farenheit (about .2W) ((I'm basing these numbers off of BTU calculators, YMMV)). When you consider we will be pulling quite a bit of air through the vape each hit, it becomes apparent to me that there is no way to insulate the element without changing the design of the vaporizer to operate under conduction heating instead.

With careful engineering, one could make the process as efficient as possible, minimize heat leakage and wasted energy, but as long as what you are trying to achieve is a convection vaporizer, you will always have to deal with the constant stream of cold air entering the unit.

There is no video yet, expect the Kickstarter a week after the video, unless they have changed plans. When they post a video I will cross it on over here unless someone beats me.

But zenpens in Titanium and coloured
