The interest to me is not that the technology cannot defeat the zero-sum nature of thermodynamics; rather it is the fact that the RAW MATERIAL for the finished product is so readily obtainable. Electricity to power the radio-wave-generator can be produced with water and coal and wind and trash and in the not too distant future, with organic-waste-eating bacteria. If we can produce a fuel to power vehicles and that fuel does not start out as light sweet crude, and the process is less costly than the process for refining gasoline, including the hidden costs such as the monetary and intangible costs of militaristic interventions to secure a supply of the raw material, then we have made progress.
Please note that his radio waves does not make a saline solution burnable forever, just in the presence of said waves, which makes the technology rather limited (because a wave generator that can crack the bond between the hydrogen and oxygen atoms is going to be rather bulky). It also has to be rather efficient, otherwise you could just split the water using old fashioned electrolysis, which is simpler, safer and easier to do (no complicated technology, just add electricity to water). A saline solution is also quite much harder to store than distilled water since it's quite corrosive to most metals. And then there's the big problem with burning hydrogen, since it has a tendency to dilute metals making them really brittle, esp. steel alloys. This reduces the possibilities even further since a normal Otto engine could not run on hydrogen for more than maybe a couple hundred hours before the piston liners begin to crack. One solution would be to fashion everything from the holding tank to the combustion chamber in titanium, or at least line it with titanium, but that would get costly, and fast (my father used to work for a company that made marine diesel engines, and their coolant systems where made out of titanium).
New technology is always interesting and to benefit for mankind, but one shouldn't think that every new little thing is going to solve a worldwide problem.
