The fact is that generators/alternators in cars are capable of producing much more current in most cases than they actually produce.

This is exactly what I said in my post. An alternator has excess capacity, but not excess output.

Yes, the alternator usually has the capacity to produce more than the electrical system of the vehicle typically demands, but that's not excess output, it's excess capacity.

None of that makes the hyrogen electrolysis unit create a net gain in engine efficiency. It simply can't, unless there is some part of the process which is greater than 100% efficient.

Ummmm I hate to say this, but this is what I've said too.
