As the electrical load increases the mechanical load on the engine does not.

Free energy! Get as much electricity as you want from any size engine!

Take a physics class before you embarass yourself anymore.

"Take a physics class before you embarass yourself anymore."

Wow, go easy. Not everyone is as brilliant as you are.

But I would say, an alternator under load is not nearly as costly to run, in terms of mechanical load, as a running A/C compressor. It's not free energy, but it is low cost.

HSE,

Free energy? Nobody claimed that. And it is you that should take a physics class; particularly E&M and/or Machine Elements.

As the alternator spins, it converts mechanical to electrical, we all know that. But any electrical energy above and beyond what the appliances use and the battery is recharged with is wasted. The engine does not allocate less mechanical energy to be converted to electrical as it sees fit. So what the poster above was saying is that as the electrical load increases, it does not rob the engine of power, but is just being more efficient with the electrical energy generated.

You quit embarrassing YOURself.

Free energy!

I must have missed it. Where is the FREE energy mentioned here? I had impression that it was about improving the efficiency. Please explain where I am wrong.
