The process of electrolysis to produce hydrogen will not produce enough to make any difference. Most all these scams have one great limitation, physics. Any energy you use to make the hydrogen (from the car batt. ) has to come from the engine. The more hydrogen you make the more energy you need. Then you have the losses from conversion. The guys from mythbusters tested these devices, none worked. Like Trumpy said, the smaller the vehicle, the less energy it takes. The internal combustion engine is very inefficient, open the hood, what produces the heat? All that heat is wasted energy not sent to the drive wheels. You still paid for it! Robert
