Pardon this post as my first and probably only one. I have read about HHOs for several years and am aware of the laws of physics that basically mark HHO as a scam. So I had written it off some time ago.
However, a friend who I trust who is a little bit of a mad scientist has experimented with HHO quite a bit. He drives a naturally aspirated 1.6 liter diesel Volkswagen that is normally a dog. He emerged today with one of the most sophisticated looking HHOs I have seen that uses stainless steel plates with large surface area to give electrolysis to the water.
He says that he messed with HHO as well and it gave little or no performance but via assistance of a friend of his who has chemical engineering experience they have been able to basically "hydrogenate" the water so it has significantly higher hydrogen content and that it actually works in this function.
He is very confident in it to the extent he is willing to build me one and lend it to me and see for myself also using his water. I must say I gave the normally stinky Volkwagen a sniff and you could tell its emissions characteristics were noticeably improved at least... It wasn't black or smokey like it normally is...
So this really has me thinking/wondering.. If extra energy is somehow placed into the water couldn't this possibly change the output of the HHO?
