Trog: You might be able to pull this off. What if we threw away the whole battery/atomizer part of the e-cig and turned the design around. The cart is in front. Then, instead of a heating coil, we use a solid atomizer (nichrome lump?) and heat it with a short laser blast? You're a DealExtreme freak, too, so look at
DealExtreme: $43.65 High-Power 200mW Red Laser Pen (Burns Match + Visible Beam Daytime).
As of August, we in the U.S. can't buy these. Can't ship them within our boundaries. Good old FDA stepped in (we've all heard of that regulatory agency, right?). Read the first "review" post for this item and anyone will understand why it's banned. The idiot buyer/poster blinded the neighbor's cat -- for fun.
Anyhow, you could buy one. Focus it with a new lens. Give it a manual push button trigger. Aim the beam inside the tube away from the user (and incorporate some kind of block for safety). It should instantly heat an atomizer.
If the atomizer is the problem with current devices, invent a new atomizer.
