My son and I have both used HHO as an additive to our diesel trucks and it makes a nice difference. The diesels have more power and burn much cleaner. So I am a fan of using HHO. HHO when burned is already a perfectly balanced mixture of oxygen and hydrogen. So when it burns the oxygen gets used completely up so there is none left to combine with the hexane. The advantage to using it with a diesel or gasoline engine is the extra heat helps the regular fuel to burn more completely with the normal amount of oxygen that is taken into the combustion chamber. In the system shown there is no other source of oxygen that I can see until the hexane gets to the end of the pipe and enters the room. That is why I believe he is only burning hexane at the end of the pipe. I am most definitely not a chemist so I could be entirely wrong about all this. This is just my opinion based on having used HHO personally.

Added hexane

I also watched the video and he clearly says and it is included in the info below the video that he is adding hexane to the HHO. To me it appears he is burning the hexane as it is coming out with the steam. I am not sure why he thinks that is something special but maybe I missed that part. If you saw something I didn't please share what that was. I have spent some time working with HHO but I am not sure where the hexane part comes in or why he added it.
