A cursory knowledge of physics will instruct you that there is no free energy. To seperate the hydrogen from the oxygen in the water molecule takes at least as much energy as it gives back. Where does that energy come from?
We'll have to burn oil or coal or use nuclear energy to boil water to run a turbine to create the electricity to electrolyze the water. In a more enlightened scheme, we could use wind or solar, or some other renewable energy, but the fact remains, we have to put at least as much energy into the system as we hope to get out of it.
The only advantage of this is that electricity cannot be easily stored, so this is a way of storing the energy, but keep in mind that both oxygen and hydrogen gasses are extremely corrosive, and prospects for long term safe storage introduce an expensive limitation.
Don't be fooled by the fact that the Pentagon is in on it. They spent millions studying use of psychics in warfare.
The water fuel gas is not even a new scam. It's reintroduced every few years. Here are some of the recent discussions at James Randi's site of this particular version. The energy from water and other free energy scams have been with us for more than a century. You'd think that one of them would pan out.
FIRE WATER
Incredible! We are apparently immersed in a scientifically-ignorant culture in which the media can’t figure out the simplest of what would have been a grade-school science project for my generation. Go to www.randi.org/media/WaterFuel.wmv and be appalled at what “inventor” Denny Klein is selling to FOX26 News in Clearwater, Florida, via their excited reporter Craig Patrick, as a system that will run a car for 100 miles “fueled” solely by four ounces of water! In the video, a hydrogen torch using “HHO technology” that Klein demonstrates, is described by ridiculous expressions such as, “hotter than the surface of the Sun,” and we’re told that it takes “only seconds to literally burn a hole through charcoal.” Duh! Charcoal burns, dummy!
The FOX video shows Klein holding the tip of the welder between his fingers, which, they marvel, “remains cool to the touch.” Duh! again. Any of this sort of torch acts the same. The tip is cool because the compressed gas, as it decompresses and exits, makes the metal tip cold. It’s only when the mixed gases – hydrogen and oxygen, in this case – burn, that heat is produced, and that happens just beyond the tip. WHERE’S THE MIRACLE HERE? Clearwater’s FOX TV tells us, “No other gas will do this." Wrong, juvenile, and naïve. Add, stupid.
We’re told, in the FOX video, that “people still have trouble believing him” when Klein tells them that his fuel is water. Small wonder. That water has to first be broken down into hydrogen and oxygen through a method known as electrolysis. That process was discovered back in the 1800s, and it uses more energy than can be gained from it by burning the two components – that’s called the Conservation of Energy law, and it hasn’t yet been repealed. Cars that run “on water” have been re-invented every few years. Recently there was Steven Horvath in Australia, who sold a lot of stock to losers, Henry Garrett in Texas – in 1935 – and Stanley Meyer, who was convicted of fraud in 1996. Andrija Puharich – who also “discovered” Uri Geller! – Archie Blue, Bob Boyce, Carl Cella, Charles H. Garrett, Daniel Dingel, Hector Pierre Vaes, Nakamatsu Yoshiro, Sam Leslie Leach, Stanley Meyer, and scores of others, all came up with this same insane idea, and all fell on their collective nose.

But, it turns out that there was an Australian named Yull Brown who in 1973 "invented" what he called, “Brown's Gas” which is obtained by simply electrolyzing water and mixing together the two parts of hydrogen and one part of oxygen that are the result, rather than conducting the two gases to separate tanks for compression and storage, as is usually done. That is just what Klein is doing. No known difference exists between the many claimed varieties of this mixture, which is used in regular 2-tank oxy-hydrogen torches to attain very high temperatures. The already-mixed gas is also known by various trade names such as Aquygen, Di-Hydroxy, Green Gas, HHO gas (as we’ve seen), Hydroxy, Klein gas (named for Dennis Klein), and Watergas.
