This isn't exactly true. The only water vapor that would enter the the exhaust stream would be from inefficient hydrogen burn. Burnt hydrogen is helium and is not a component in water so an inefficient burn will be the only cause of water coming out of the exhaust. The unspent (inefficiently burnt) hydrogen will automatically recombine with any surrounding oxygen making the water vapor.
That's the basis of the hydrogen fuel cell. Reverse electrolysis (recombination of hydrogen and oxygen) creates a charge naturally and is used to power an electric motor, the only emission is water. So, insufficient combustion of hydrogen within the cylinder is the only reason that water would come out of the exhaust ports in an HHO system.
This is mainly what turned me away from digging further into hydrogen/hydroxy systems. Permanent magnet alternators can be introduced into the engine bay, running off of the same belts without regulators for higher production but the bottom line is that I would be using up the basic components of water while the planet currently seems to be having issues surrounding water. Anyway, I'm not what one would consider "green" but I do like efficiency. The more efficient these systems become and the burn becomes, it's stands to reason that the more water problems we will have.
It is amazing to me that sites like treehugger and other green sites endorse HHO for internal combustion. On a side note, I'm all for the home enthusiast building a system like this and building it well but mass production and legislation requiring this scares me a bit.
