So you use energy to produce/separate hydrogen from the cars alternator then you run the car on the hydrogen?
Do you get where I'm going with this? Anyway the point I'm making is that you require energy to separate hydrogen from whatever (usually water). Then when the hydrogen recombines with oxygen it produces energy making the car run. The enrgy to separate the hydrogen must come from an external source (otherwise it would be perpetual motion and that's a no no) usually that energy comes from electricity which is generated by fossil fuels.
The point is that hydrogen is an energy storage device. It does not "create" energy. That energy comes from somewhere else.
The Farraday principle.
It is a fallacy that you need more energy to split hydrogen than what you can get from burning the hydrogen.
I can produce 65 litres of Hydrogen per minute using 12 volt 2 amps.
Unfortunately, when installed into the engine,it does not work.
My alternator produces 95 amps.
This melts the plastic from the wires.
( a extremely dangerous situation, you will agree)
I need a circuit board to reduce the Amps drawn to 2 amps.
You also need a LM555 circuit board to send electric pulses to the electrolite.
I have the complete plans for this.
As i am electronically disadvantaged, somebody else builds the circuit boards.
Outsidse the car, this works fine, as i can control the amps drawn.
Inside the car it is a different story.
