I setup a screw-wick on my helping hands thingee, and oddly enough it actually worked. That's a long way from saying it would work well inside an atty, but it is intriguing. I clamped the screw/coil in place, threaded end up, and attached a tiny plastic bottle of e-liquid to the top of the screw. I gave it power and it continued to feed and produce vapor. Then the plastic bottle melted and fell after about 30 seconds. Of course the actual tank in a design like this would be made of glass or metal or something else that's heat-resistant, so melting shouldn't be a problem.
