I appreciate your sharing the review. This development has gotten me doing some rather wild "what-iffing."
Specifically this: A non-liquid substance seems more versatile in how it could be used in a delivery device--no drip, no spill, more gravity-resistant. Plus a little, in volume, goes a long way. Suppose it could be stuffed into a thin tube, a portion of which is highly heatable metal, maybe the thickness of a ball-point pen cartridge, and that tube inserted into a reusable, heat resistant cylinder the exact size of a cigarette. Suppose further that the inner tube could be ignited by a match or lighter to heat the metal. The puffing action would (somehow) draw a bit of the gel into the hot area, and the heat and gel would last the approximate duration of smoking a cigarette. Suppose even further that without a battery the whole affair could be made in a weight more or less comparable to a cigarette, such that it could be dangled comfortably in the mouth, etc.
Put it all together with some engineering even more geared to the smoking experience than has been applied even to the e-cigarette. Could be quite a step!
