That machine does not burn water, it burns the hydrogen that is being released by the NaCl (sodium chloride, salt) molecules interacting with the radio waves in a way I have no idea about. Since water is made of 2 hydrogen and one oxygen molecule, there is a great chance that the reaction after the burning releases oxygen back in to the atmosphere which will combine with free hydrogen atoms , form H20 molecules, pile up on clouds, rain back on the oceans and voila you got your salty water back.
