Sorry for the late response- got busy. Yes, I remember reading about Stan Meyer: he was a VERY prolific inventor (the patent office fast-tracked all his applications because he submitted so many, so often). The problem with his car is the fact that for it to do what he claimed, it would violate the first two laws of thermodynamics (1-you cannot create or destroy energy, only convert it, and 2- Entropy {lack of energy} will always build up in a closed system). He clearly built an operating car with a drivetrain that utilized an Electrolysis unit. I would like to know how far the car could travel reliably, because I suspect that if the car was in fact running off of Hydrogen that was being split out of water at that moment, most likely the battery was being heavily drained to run the Electrolysis unit. The engine's alternator would continue to try to re-charge the battery, but would not be able to keep up- the battery would eventually run down. Now maybe, with a modern battery scavenged from a plug-in hybrid, someone could get enough range out of this set-up to make it worthwhile (i.e: charge the battery, fill the water tank, and drive), but I have my doubts that it would be as efficient as just having more batteries and an electric motor. Also, I have read about people claiming to be using these Electrolysis units in their cars to inject Hydrogen into the air intake of their gas cars, supposedly radically increasing their fuel mileage. I have no idea how safe this idea is: I wouldn't try it with any car I cared about, that's for sure. I have also read about people adding various chemicals to the water to increase the amount of Hydrogen released, supposedly past the "Break Even" point. The questions I have regarding the use of chemical solutions are 1-What's the by-product and what will you have to do to get rid of it, and 2- what will any by-products do to the Electrolysis unit. Stan was a very smart, self-educated, and well regarded individual (he was involved in the Reagan Era "Star Wars" defense program) regardless of what people think about his car. Sorry for the extreme length of the response, but it's not a simple subject by any means.
