Here's the link: http://www.popsci.com/scitech/article/2007-11/turning-water-fuel I find the idea interesting that the radio waves may assist in breaking the oxygen-hydrogen bonds of the water molecule. But, why should this effect only exist with salt water and not pure water? Salt water is ionic and permits current flow? The applicability of such an idea for a potential fuel seems very far off. The radio wave generator requires a large energy input compared to the output from ignited gases.
