Burning water?

Here is a story about using radio waves to get hydrogen out of salt water.
Apparently no one has calculated how much energy you have to put in to get some amount of energy out. That kind of quantitative info is not important for publishing a story these days.
Things with numbers = boring.
Anyway, it's probably nothing, but in case it turns out to be the greatest discovery of the century it needs to be noted here on YR. Once someone bothers to do some math we'll know.
