Sigh ...

The fringes of the energy industry are populated by people who "heard about a guy whose second cousin read about a pill that you put in your gas tank that lets you get 100 mpg on a gallon of water." Inevitably, the "oil companies bought it up and are hiding it." - presumably because they'd rather invest hundreds of millions of dollars extracting oil from subsea wells than produce little pills.

There's a reason why credible energy systems research proceeds slowly. Its hard work, with verification at every step along the way. Methods and results are published in peer-reviewed journals for the entire scientific community to critique.

If you heard about some guy who did it alone in his garage, you can pretty much be sure it ain't so. Inevitably, these systems are never allowed to be independently tested, or "have a problem" just before a major demonstration. I'm not trying to criticize the inventive spirit, but the inventor needs to submit their work for verification if they expect to be taken seriously.

Before you swallow any claims like the one in this post, ask for independently verified proof. If they can't produce it, move on.
