Thanks man, makes me feel like I won an award coming from one of the coil masters
. It didn't want to be close together 
but some pinchin, heatin, quenchin, I made that coil my b... I found your thread about Rene 41 and the date was around the time I bought my first ecig, a volcano inferno. I remember thinking how dumb subohm (still hate that word) was
now I can't really get a decent vape over .8 ohms. Funny how things change.
yeah, in an ideal situation the only resistance would be the coil and the only energy lost would be in heating that coil, that's the whole point of trying to eliminate loses elsewhere, energy lost else ware is energy that could have went into the vape
I see... so why aren't we all just using chunks of this:
PTC Ceramic elements: PTC ceramic: this material is named for its positive thermal coefficient of resistance (i.e., resistance increases upon heating). Most ceramics have a negative coefficient, whereas most metals have positive values. While metals do become slightly more resistant at higher temperatures, this class of ceramics (often barium titanate and lead titanate composites) has a highly nonlinear thermal response, so that it becomes extremely resistive above a composition-dependent threshold temperature. This behavior causes the material to act as its own thermostat, since current passes when it is cool, and does not when it is hot. Thin films of this material are used in automotive rear-window defrost heaters, and honeycomb-shaped elements are used in more expensive hair dryers and space heaters.
Or even strips of glass??
Uh... you can:

Coated Glass for Transparent Heating Elements
Wednesday, 22 October 2008
This coated glass can be used in high-humidity and high-altitude applications such as architectural and aircraft windows.
Applying an electric current to specially coated glass results in radiant heat energy. This process creates a transparent heating element with near- uniform surface temperatures. Manufacturing the heating element requires an ordinary pane of float glass. A fluorine-doped tin oxide coating (SnO2:F) measuring 0.25 micron thick is applied to one surface of the glass during fabrication. The coating conducts electricity, has a very tightly controlled resistance, has no appreciable color or structure, and is quite transparent. The coating has low emissivity properties that help contribute to the efficiency of the heated glass.

So, why can't one of you cut a strip of the above, and attach it to metal mounting brackets, so we can just drop our juice on the slice of glass pane?
Where'd everyone go?
Ok, so if you got a thin strip of that glass, you could wrap ends with silver foil, then each end wrap around the + and - screw (could machine a far more elegant solution than this, just saying for experiment sake). Stuff some cotton ball under the glass pane, and you'd eliminate oxidation and use it for years, cut to the correct resistance size already, and it would be a perma solution and you don't need a stove top designed atomizer either... could mount it permanently on top of the dibi and it could outlast the battery spring even
. Right? Right?
It would be impervious to smelly organics, and maybe oxidation too? I guess that would depend on the coating... if the coating is slick like the glass (think silver mirror backing), nothing would stick to it, and you could just rinse anything off it.... the entire atomizer can be pure glass. Borosilicate withstands 1700 degrees, not going to be affected by vaporizer temps. Right right?

Ok, so we add that to the Dibi, and we'll have a new vaporizer that will revolutionize vaping and make every atomizer obsolete. What's not to like?
Come on, why'd everyone get quiet?

I found the PTC ceramic... looks sized for an atomizer already... wouldn't this work for a quick solution? It's 60 watts already and comes with 4 of em for $12.99... why can't we use this instead of coils? Since there's 4 of em, can one of you make me one too if we don't need coils anymore?

This might work too... replacement ceramic coil for replacing soldering iron heating elements:

You guys are scaring me with the silence...
Wasn't that a viable idea?

R41 is stronger and harder to form than 18-8 SS and has higher heat resistance. Interesting tidbit: Panels of it (and Beryllium also) were used on the Mercury and Gemini capsules for the outer skin due to its high heat resistance. They were attached such that they could expand due to the heat. The Apollo capsule was larger and they went to ceramics since R41 would need to be thick enough that the ceramics required would be lighter. R41 is still used in aerospace applications and also in jet engines.
that glass heats very slow and to a very low temp, would never work for vaping really. the ceramic elements same thing, have you ever used a 60w soldering iron? yes about 2 minutes after you power it up it will make more than enough power to vaporize extremely well but it's also very slow heating, you wouldn't start to see the first wisp of vapor for like 25 seconds
resistance wire is efficient and easy to work with and works well enough with wicking and squonking

Too late
VapingDonuts
From what I have heard they are not the answer
Oooh. Heating speed... hrm. So it's the difference between heating something on a glass flame vs electric coil vs glass cook top... hrm.
Vaping donuts?! I guess that heats slow too??
The consensus on the vaping donuts was they take too long to heat up and they don't cool down right away either. They also heated up the atomizer quite a bit too. Quite hot to the touch. 
yeah ceramic is not instant. I think some ceramics like the soldering iron ones are actually coils of resistance wire embedded in ceramic for the heat distribution properties of the ceramic, but it is a barrier and will slow things down, don't see any potential benefit to the ceramic, resistance wire coils can be much more compact for the amount of energy they can dissipate. I don't know much about actual resistance ceramic, maybe that's what vaping donuts are? still not going to respond like resistance wire
