Looking more into the details, and for instance the videos, one see that the "inventor" collects water in a small pool next to his house which is full of seaweeds (it happens in Florida). An obvious possible explanation is that the fuel is just methane diluted to saturation in the water. The micro wave shaking produces the same effect as when shaking a bear, champagne or a soda. I don't know if this is the right explanation, but apparently this possibility has never been checked. Looking at the video it seem that the flame is not lasting forever. This would be normal once the methane is exhausted. It is totally misleading to say that this guy is producing energy from salt.
