Okay, this HAS to be some kind of hoax..right?

From here:

"I get 100 miles to the ounce on water," Anthony Brown told WJXX-TV in Jacksonville. "I can run any water – distilled water, drinking water, tap water."

"Right now it's using a little bit of gas. If anything, it's getting a fuel vapor. I've got the fuel injection system shut down," he added.

...

"Can we pull the cover off and uh get to the injector part of it?" asked a technician with Whites Automotive.

"Sure," said Brown. "When you separate the water from the oxygen from the hydrogen, it cooks and it cooks down to a brown color. We're not having any waste product off of it. Everything is consumed and burned."

...

The station's report has prompted a cross-section of comments on its messageboard, including:

Standard Oil, Exxon, BP and all of OPEC will be on him now like buzzards on a carcass.

He is definitely not inventing anything new, the technology has been out for a while ... . There are several places to buy the conversion plans/kits. One guy in California converted his vehicle and now does the conversion work for those willing to pay him to do it. My question is why are the auto makers not taking this technology and running with to mass produce vehicles? Is Big Oil paying them not to go with this technology?

This same sort of claim has been made for over a century, and has been proven a hoax or fraud every time. I could explain all the ways it violates the laws of thermodynamics. The fact that he claims to be supporting a ministry were included in the report is further proof that the interviewer didn't have an ounce of sense. If it was a real science breakthrough, the religious claims wouldn't matter. Scammers love to claim they're working for God. It engenders good feelings and thus an added measure of trust from the simple-minded fools who might be taken in by their claims.
Last year, WND reported on another Florida man looking for an energy breakthrough with water.

John Kanzius, a retired broadcast engineer from Sanibel Island, Fla., experimented with radio waves and salt water.

"On our way to try to do desalinization, we came up with something that burns, and it looks in this case that salt water perhaps could be used as a fuel to replace the carbon footsteps that we've been using all these years, i.e., fossil fuels," Kanzius said.
