That would certainly help some probably with assembly by making the wick/coil combinations smaller... but to get the best flavor you don't want to decrease the total surface area of a coil which also help keeps from burning the juice at higher voltage/power settings as well as providing more area to vaporize the juice.
Everything we do... comes with a compromise in some other area. Larger gauge wires take up more space for a particular resistance setting but can provide more flavor... smaller gauge is just the opposite of course with the advantage being they take up less room but at a loss of flavor since you have less surface area to vaporize with. Making a micro coil, ie just spacing the wires closer together but retaining the same gauge... can help and retains the same surface area but are trickier to build since you increase the chance of shorting across the coils that may end up touching.
The precursor to today's electronic cigarette ( not the first made, but the first using the design similar to what we use today ) used a piezo quartz hypersonic atomizer to vaporise the liquid from a fiberfil carto... The issue with these were cost and overall lifespan related... so we switched to using a coil to atomize with and the benefit was a much lower cost so throwing out a bad/dead one wasn't as big of a deal. So while using a coil design may just be "more of the same"... the advantage is in the cost savings vs a higher tech solution such as the piezo quartz as just one example.
The advantages of a coil are really hard to beat... they are low tech, easy to build ( relatively ) at least when compared to other technologies we have at present. Really the only downside I see to the Medusa is the complexity... and even with what I know, I can't think of something to better the concept without taking away from some of the advantages it does provide. There have already been several suggestions to improve the design without changing the concept it's built on ( some are posted in the other thread... like adding additional vents in a manner that each coil has good air flow by it )... check out the other thread for some of the other suggestions.
drumroll, very nice write up, much appreciated
