I think not. Recently I came across a article somewhere that said hydrogen will dissolve into the metal and brake down the metallic structure, making it sound like using dry hho in the engine will destroy it. This got me thinking. The only way that hydrogen will destroy metallic structures is if the metal is completed submersed in an environment containing hydrogen, this is the only way that hydrogen will have time to dissolve into the metal.  There are 3 major things that contradict what they said in the article:

• Major car companies have already shown the entire world that basic cars can be modified to run on hydrogen. Ford, GM, Honda, BMW have all developed both concept and working vehicles that run on hydrogen with better designs set for future mass production.

Notice how the engine looks nearly identical to a regular engine, with the exception of the hydrogen lines and gauge system hooked up to it..

• The only way hydrogen can dissolve into metals and break down the structure… is to submerse the metal entirely in an environment full of hydrogen for an extended period of time.. Dissolving anything is a process that takes time (unless corrosive acid is being used, which then will take a few minutes). But we are not using sulfuric acid to run our engines… we are using hydrogen.
• The hydrogen would not have time to dissolve into the engine metal anyway because of combustion. The hydrogen is sent directly to the combustion chamber, which is then combusted and what leftover molecules (if any) are reunited as steam vapor which is then expelled directly through the exhaust valves (remember the engine is still a few hundred degrees). Then travels out the exhaust system where it cool with the outside air into pure, clean h2o.
• Storage is also not an issue with dry hho since the hydrogen is produced on demand and is used right away. The car companies have found their ways with the storage by making the tanks from carbon fiber which makes the tanks stronger and eliminates the rare occurrence of explosion from impact since carbon fiber will not explode like a steel or aluminum container. (This doesn’t apply to people with dry hho systems anyway).
• Running combustion engines on hydrogen, that previously used gasoline, will actually clean out the carbon and gunk from the engine making the life of the engine actually last longer. (In theory, proper hydrogen systems should supply more power to the engine since it is a very powerful fuel source, the sun uses it, and there isn’t any gunk clogging up the horsepower).

So clearly whoever wrote the post on hydrogen destroying metal did not realize that this does not apply to combustion engines and hydrogen actually improves the function, life and power of the engine. The car companies and other successful entrepreneurs have already proved this statement.
