I think we could actually pop a hole in the back of the glass and run 1 wire right thru the glass out with the fibers,,
that way you could pop a rubber plug out with contact for one side of a battery and juice stopper fill spot. all in one. .. and the case could be the ground for the other connection to the coil right by the coil.. like a spring tab idea..
It would be nice to send one wire through the glass itself. Or even both, and make the back end of the glass container look like an AC Plug, so it can just slide in and slide out for replacing...
Interesting idea. I like how the nicrome wick is in direct contact with the reservoir. The glass is still going to be a concern for some people but you could use many different types of material for the reservoir I would think like metal with ceramic cap so you could remove and replace the atomizer. 8ml is a lot of liquid I think most people would be happy with 2ml to 3ml. It wouldn't need to slide out if you made a hole & plug on the side and the cap removed the section covering the plug.
Metal and ceramic should work just fine too. I'm really diggin' glass because of its low reactivity. With metals and plastics you have to worry about chemicals leeching in. But if it works, I'll throw the glass atomizer around and see what kind of abuse it can take before breaking/shattering
. 8ml
is a lot of liquid, but that's my calculation from this drawing, scaled up to a 510's thickness (~9-10mm). 1ml is enough for me, really, so this should allow us either high capacity or a much shorter ecig.
Only downside I can forsee is how hot the end will get where your mouth contacts the atomizer.
my 2 cents

This could be an issue. I put it next to the mouth hoping for warmer vapor. Not sure if that's a good idea or not; luckily, this design could be easily adapted for the opposite orientation.
I think it probably would get hot. Since that air space is not really needed an insulating material could be positioned around that casing.
I'm not sure if I'm just a real lightweight when it comes to vaping, but I've never gotten the outside of the atomizer to be more than slightly warm, even after a long pull. But as I said in my reply to Dan's comment, the bottle/container could be easily flipped around.
In addition, here's a link to a
NIST page regarding the thermal conductibity of liquids and gasses. alchohol may very well be a better conductor of heat than air (so would Diethylene Glycol or amonia for that matter). If considering a liquid filled bulb/atty, there is also the potential for galvanic response of the liquid which needs to be considered, ie will the nicrome wire corrode/react (which is why water might not be the best choice, but it might be!) here's another link to
fluid thermal conductivity.
Glass itself whether liquid or gas filled wll probably stay hot long after it gets hot. Carbon Fiber might work better, to quote wikipedia "heat-treated mesophase-pitch-derived carbon fibers have high
Young's modulus and high
thermal conductivity.". A sphere has the least surface area, so a round CF ball packed with a nichrome coil might heat then cool very quickly and would avoid metal to liquid contact. Plus CF almost never wears out - have you ever seen CF brake rotors glowing cherry red on a Formula1 car..
Thanks for this post. Some great ideas in here. The glass, at least the kind I used in my last working prototype, does stay pretty hot. I was thinking of perhaps trying out that last concept image I posted with a carbon fiber wick (although it takes us back to traditional coil-on-wick attys).
This Nichrome coil sphere is something I had been thinking of, but how would one go about doing that, especially without letting the Nichrome short itself out?
Could u elaborate on that moktarino?/ any pics whats the setup look like..
It looks like a regular Nichrome coil except it has a very small amount of glass sealing the entire coil. It's comparable to my original "bulb" concept in a way, but his is way better, smaller, and more efficient
