You guys have it All Backwards.
Instead of trying to Suppress the Cloud being Exhaled, I say Illuminate the Cloud being Inhaled.
Remove the Heating Coil and Replace it with a Micro-Pulse "True" Atomizer. So when the User pushes the Power Button, there is a Ultra Fine Mist of e-liquid created which is Mixed with the Inhaled Air.
Hmmmm, novel idea, not sure I quite understand but a little google will fix that right up... but basically you're saying there will never be a vapor, I'll just be getting a liquid mist?
I'd try it if someone else had it but I'm not about to invest in it (probably, i am a sucker for new vape toys lol).... I can't stand when even the little bit of tank spit happens, and that sounds like just a really fancy tank spit (tough probably far less painful on the throat).
What does the mist feel like, how does it change vape flavor? does it increase throat hit requiring a lower mg? what totally basic differences are there that I haven't even though of to ask... and where do you find such a thing?
