Thoughts on HAFC & PICC

I was reading the closed thread about PICC (Pre-Ignition Catalytic Converter) and HAFC miracle devices. I wanted to comment on those ideas. These are simple assumptions from a non-engineer. 1. The PICC would have to be hot in order to cause the reaction. A computer would be required to adjust the fuel mixture properly when the engine is cold (first started). 2. The HAFC would definitely provide less power than it consumes. No forced reaction will be at 100% efficiency. Hence some testing showing a loss in MPG. 3. The only way that the HAFC would be beneficial is if the energy it consumed creating the Hydrogen and Oxygen gasses is if that energy would otherwise have been lost. Perhaps the automobile's alternator is generating far more electricity than is necessary to run the vehicle, operate the accessories and recharge the battery. If your car's alternator generates enough electricity to run your headlights, radio, windshield wipers, power steering, power brakes, power windows, etc... where does that electricity go when you are not using all of those? One thing that drivers notice is that when the air conditioning is turned on, the car's apparent power seems to diminish. So my guess is that when the AC is off, the energy required to run the AC is no longer diverted from propelling the vehicle. Is this standard practice for all accessories/electrical features? If it is not, then there would be excess electricity created, with an unnecessary drop in MPG efficiency. This amount may be miniscule, or perhaps it is significant. If the typical amount of excess electricity generated by the alternator is significant, then it may be beneficial to apply it to an HAFC. If it would otherwise be wasted, then even an inefficient HAFC will still generate some benefit. Excess electricity would have no benefit for an internal combustion engine (ICE), whereas Hydrogen and Oxygen gasses would. Could someone please explain if adding Hydrogen gas into the fuel mixture of a gasoline engine would work well, or if it would require significant modification of the engine? Also, ICEs generate large amounts of heat. I know photovoltaics (solar cells) can generate electricity from sunlight. Is there a similar method for producing electricity from heat? I am just a guest on the forum. Any responses, please also send to my email. I apologize if this thread is posted in the wrong category. I think the original topic was in this category.
