Also, that's what clearomizers are supposed to be. They succeed/fail to varying degrees. I really like the Vision Vivi Nova (available from a lot of vendors).
The Genesis style atomizers are another way to get at that idea, from the $25 Griffin to the $~150 DID and Z-Atty. Also, the GG Odysseus.
There are 2-chamber tanks as well that are somewhat between the way the two work. The Smoktech Vivi Tank is one of them, the RA Tank is another.
The only one I've any experience with is the VN, and I really like it. I've got a 2-chamber version coming in this week that I have high hopes for. If that goes well, I might look into the others, but realistically
they'd have to be very impressive to unseat the Vivi Nova from it's perch (for me).
