As you have probably already seen Fox26 in Houston, TX did a story on Denny Klein a couple of years ago. That story has since made it way around the world via youtube and other video sites. I saw the story when it aired and directed many friends to the video on youtube. Then not too long ago I saw a teaser for a related story about turning your car into a water burning hybrid. I truly thought they were about to do another story about the technology of using water as a fuel. That didn't turn out to be the case. They had Scotty Kilmer a quack mechanic who does a weekend segment on a different Houston News station come on as their "expert" to debunk all of this HHO stuff.
When I saw the story I was stunned. It totally ignored the previous story that I saw. So I decided to do a little research to see if there was more info on the web. That's when I found out that the website they're showing in the news report appears to be Denny Klein's website.(He's the guy interviewed in the first story. Who says in that story that the car could run on water exclusively, but is currently running as a gas/water hybrid just like the plans say.)
Also, if the person controlling the mouse on that webpage in the story would have scrolled down a bit, you would have seen the original story THEY did that has now become so popular on youtube.(Because it's embedded on the bottom of the page they're on.)
This debunking story convinced me to do my own personal test of this by going to the website listed in the report and buying the information to build my own Water Hybrid.
I'll post back when I finish with my own results.
