The failed hho scams are many. The only really active public company now pushin the hho technology is HLNT. You'll find some interestin threads on their Ihub board. None more interestin than the present one started by a poster named xrayview. I've also posted many links to HLNY directors as well as their various sub companies and their ownership, status as a company and their knowledge of the hho technology they claim to be selling.
Those interested should read the latest posts and responses to xrayview. As I said, I've also posted on the subject but those posts are no longer available to read.
