I'll have to check out the gas dealy, like I said not exactly familiar with it my comments were just a thought.
As for the "carb" and dilution of vapour, sure I guess it would add air to it and yes you do have to suck abit more to get the vapour out of the "jar" either way that o2 goes in after the product is vapourized therefor there is no combustion hense no smoke. There does not actually have to be a visible traditional looking flame to prove combustion, it can simply glow resulting in smoke - In fact there is more smoke with incomplete combustion plus with that comes Carbon Monoxide. A vape does not produce either, just fumes as there is no oxygen flowing through the combustion chamber.
I also own several different bongs and vape's have tried even more, I found this one great. No need for me to make myself feel better about what I bought because I tend not to worry about money. The security alarm business is great. Just was passing on thoughts like you are. Freedom of thought and speech is what makes it great to live in a relatively democratic society. Some friends prefer the fancier more expensive vapes, so I still keep them around for them, plus they make for interesting decor in the office(Not Ikea but....My staff get a kick out of it)
At the end of the day we do what we do, smoke what we smoke and have the right to choose how to smoke it. I could go onto a value over cost comparison between the wooden box with a heating element, fan and chunk of window screen vs the "Soldering Iron", ceramic bowl and "jar" but at the end of the day I don't make any money off either so we will have to enjoy the end result, regardless of how we get there.
On that note, I think I will go take a hit or ten, I have a nice few ounces of Honey Oil..... mmmm smoooooooth
