This is pure BS. The energy to separate the hydrogen comes from the alternator which is driven by the motor. Electrolysis is inefficient. More electricity would be required for the separation than would ever be returned by injecting the hydrogen back into the motor. This is either a bald face lie or a scam. The only reason anything like this gets any play at all in the news is that the U.S. public is ignorant in all matters involving science. The reason the seller says that it takes a while to "clean out the engine" is to give him time to blow town before the pigeons come looking for him with the tar and feathers. This is the oldest line in the "gas saver" book. The saddest part is that there are people who actually fall for this rediculous shit.
