    By David Templeton, Pittsburgh Post-Gazette

    ERIE, Pa. - An Erie cancer researcher has found a way to burn salt water, a novel invention that is being touted by one chemist as the "most remarkable" water science discovery in a century.

    John Kanzius happened upon the discovery accidentally when he tried to desalinate seawater with a radio-frequency generator he developed to treat cancer. He discovered that as long as the salt water was exposed to the radio frequencies, it would burn.

    The discovery has scientists excited by the prospect of using salt water, the most abundant resource on earth, as a fuel.

    Rustum Roy, a Penn State University chemist, has held demonstrations at his State College lab to confirm his own observations.

    The radio frequencies act to weaken the bonds between the elements that make up salt water, releasing the hydrogen, Roy said. Once ignited, the hydrogen will burn as long as it is exposed to the frequencies, he said.

    The discovery is "the most remarkable in water science in 100 years," Roy said.

    "This is the most abundant element in the world. It is everywhere," Roy said. "Seeing it burn gives me the chills."

    Roy will meet this week with officials from the Department of Energy and the Department of Defense to try to obtain research funding.

    The scientists want to find out whether the energy output from the burning hydrogen — which reached a heat of more than 3,000 degrees Fahrenheit — would be enough to power a car or other heavy machinery.

    "We will get our ideas together and check this out and see where it leads," Roy said. "The potential is huge."


    What do you think, people?

    magandang invention ito... parang yung keanu reeves na movie dati - forgot the title (he was machinist who found that a certain frequency generated during the machining process encourage hydrogen release from water).

    Hmmm....parang Keanu Reeves sa Chain Reaction.

    I speculate that it will take a lot of radio power to do this. Mag papakulo na lang ako ng tubig for the meantime.

    mali pa yata pagka embed..sori mga sir....

    ok tong invention na to..sana ma improve pa para magamit sa sasakyan....at magkaroon na tyo ng isa pang alternative fuel

    Hope that nobody blocks further developments/refinements on this...

    Everyone should jump into this bandwagon as this will give us practically unlimited supply of fuel/energy....

    Actually, there's also a new kind of technology wherein solar cells are used to separate hydrogen from water.

    Researchers in Switzerland have demonstrated more-efficient water-splitting solar cells based on a cheap, abundant, and long-lasting material: rust. The advance could lead to a cheap and energy-efficient way to generate hydrogen for fuel-cell vehicles using solar energy.

    Water-splitting solar panels would have important advantages over existing technologies in terms of hydrogen production. Right now, the primary way to make hydrogen is to separate it from natural gas, a process that generates carbon dioxide and undercuts the main motivation for moving to hydrogen fuel-cell vehicles: ending dependence on fossil fuels. The current alternative is electrolysis, which uses electricity to break water into hydrogen and oxygen, with the two gases forming at opposite electrodes. Although electrolysis is costly, it can be cleaner if the source of the electricity is wind, sun, or some other carbon-free source.

    But if the source of the electricity is the sun, it would be much more efficient to use solar energy to produce hydrogen by a photochemical process inside the cell itself. By improving the efficiency of such solar panels, Michael Grätzel, chemistry professor at the Ecole Polytechnique Fédérale de Lausanne, in Switzerland, and his colleagues have taken an important step toward this goal.

    Renaming the thread also.

    The question is energy-efficiency.

    There are a number of possible ways to make salt-water burn, and, as you can see from the video, it takes continuous application of radio frequency to keep the water alight.

    Perhaps he's stumbled on the proper microwave frequency to excite the sodium ions in sea water... the release of hydrogen and sodium from sea water provides fuel for the flame in the test tube.

    The big question is... how much radio frequency is used? And how powerful is the transmitter? If the machine uses over a thousand watts of power to light just one test-tube flame, you're still using more energy than you put in... so current practical applications are really limited.

    Ang pagbalik ng comeback...

    In the news report video, it's shown that a small hydrogen fueled flame can be produced by the machine. I was wondering how much power the machine was using to produce the hydrogen for the flame?

    Anyway, it was also mentioned in the report that salt was required for the hydrogen process to happen. I was thinking the salt was providing the needed ions for the radio energy to split hydrogen from oxygen and keep them separated. My hypothesis is the RF energy is at a frequency near to the molecular bond frequency of water molecules thus breaking the bonds.

    This is almost parallel to my hypothesis that you can improve the efficiency of water electrolysis by using electrical energy "flowing" at the molecular bond frequency of water. My problem was getting high frequency high power transistors that can do it. By using RF energy, the need for high frequency high power transistors is negated.

    As for power efficiency, the problem with RF energy is it will "leak" so there will be amount of power that is not used for the wanted results. If it was used in electrolysis system I have proposed, the "leak" would have been smaller (as waste heat).
