Budge is technically correct. There is no net energy increase between converting H2 and O2 back and forth to H2O. The term he is looking for is enthalpy and applies to the First Law of Thermodynamics that is used to refute all perpetual motion machines.
H2 + O2 producing H2O is an exothermic reaction with a low activation energy required and a large decrease in potential energy (lots of heat is produced when a small spark is put to H2 burned with O2).
The reverse reaction requires an overall increase in potential energy which is why water doesn't convert to H2 and O2 without a large energy input. For this process to actually work, the burning of H2 and 02 in the presence of radio frequencies and saltwater would have to form some other compound besides H2O at an even lower potential energy where the extra released energy could be further used to help break apart additional H20 into H2 and O2. Since no claim is made to such an inert element being created, the science is extremely doubtful but a neat parlour trick nonetheless.
For those that may think this process involves a catalyst, a catalyst is not consumed and only lowers the activation energy required and not the overall difference in potential energy.
From Wikipedia: Water Fuel Cell. The water fuel cell, named by American Stanley Meyer, is a device designed to convert water into its component elements, hydrogen and oxygen (2H2O <> 2H2 + O2). The Water Fuel Cell is designed to utilize less energy to break molecular bonds than the quantity capable of being recovered by combustion of the product hydrogen and oxygen gases; the validity of the design is controversial. The water fuel cell is claimed to be able to produce several times more energy than it consumes; the source of this additional energy has not been scientifically identified therefore the theory is treated with skepticism. In practice, an engine would be connected to the output of a water fuel cell and through the combustion process convert the hydrogen back into water (2H2 + O2 <> 2H2O), which can then be vented to the fuel tank (containing water); such a practice conforms to the parameters of perpetual motion, hence conclusive scientific investigation would either verify violation of thermodynamic law or identify the source of claimed additional energy. At least one car prototype, reportedly powered by a water fuel cell, has been assembled [doubtful].
