The guy in the video has a number of things wrong:
- He said "if the wire didn't have resistance, you would have an uncontrollable amount of vapor."
Um no. You would have a dead SHORT and your battery would explode.
- He said at 3:40 "The amount of vapor is solely regulated by the device based on temperature."
Um no. That's not how it works. Temperature has nothing to do with the amount of vapor produced. You can vape at 400F and have very little vapor from one atomizer and you can vape at 400F and get a ton of vapor on another atomizer with a different build. It depends on the wire, the wraps, the heat flux and heat capacity of the wire as well as the power (watts) you put to the coil. Power = heat. However,
heat does not equal temperature. Most people don't get this and I wont bother explaining it here. It's a common mistake, so I guess I can forgive him.
- At 4:30 he begins talking about what stainless steel is, what it's comprised of, etc. He is right about the components, but he makes a few very generous assumptions. For instance, he says that chromium doesn't leach from stainless steel. He might want to take a look at some of the studies done on cookware. He also said "we wrap our food in aluminum" implying that it's safe. But he doesn't seem to bother explaining how ingesting something is a lot different from inhaling it.
- Then he begins talking about nickel carbonyl, but it's pretty clear he doesn't have any idea what he is talking about. Nickel Carbonyl is so poisonous that 30ppm (parts per million) in the air will kill an adult human. Yet, so far, I have not heard of any cases of vapers falling over dead. Simple logic tells us that if nickel carbonyl was really being produced, we'd have a lot of people being admitted to the ER with many of them dying. Yet there are no such cases. I don't think this guy is familiar with the Mond process (the chemical reaction that forms nickel carbonyl). Such a chemical reaction is not present in our atomizers.
- At 11:30, he says "Because nickel is so soft, it is water soluble."
False. Nickel is neither soft nor water soluble. Indeed, nickel is rather strong and known to be hard.
A quote from a university website:
"Nickel is a hard silver white metal, which occurs as cubic crystals. It is malleable, ductile and has superior strength and corrosion resistance. The metal is a fair conductor of heat and electricity and exhibits magnetic properties below 345°C. Five isotopes of nickel are known.
In its metallic form nickel is chemically unreactive. It is insoluble in cold and hot water and ammonia and is unaffected by concentrated nitric acid and alkalis. It is however soluble in dilute nitric acid and sparingly soluble in dilute hydrochloric and sulphuric acids.
5 minutes of Google must be hard for this guy. Unless we have hydrochloric or sulphuric acids in our e-liquids, the chances of our liquids corroding nickel is about zero.
- At 12:00 he makes a good point. Nickel should never be used on mech mods or in regulated mods in power mode. The Chinese don't do a good enough job explaining this and I am worried that someone is going to throw a nickel coil into their Atlantis and put it on a mech mod.
- At 13:23, he says "A lot of people have reported that when using temperature control, the resistance of the wire is fluctuating like crazy."
That's what
is supposed to happen and is precisely why nickel was chosen in the first place! Without the resistance changing based on heat applied (known as the temperature coefficient of resistance), temp control would not work. This is why we can't use kanthal for TC (its resistance is too stable).
I am not saying that there is no leaching of nickel from our coils. Some studies have already shown that there are metals in vapor (nickel included). However, it's unclear whether this is from the atomizer, coil, or some other source. In any case, the studies done on vapor so far have shown tiny amounts of nickel -- far below the safe daily exposure level.
Think about it: if nickel were a real problem, don't you think ANTZ would make a big stink about it?
