What puzzled me is the underlying idea I had always had that “natural” combustion was kind of clean because it’s a natural process (we burn calories, forests burn in the summer, etc).
The "natural" has been replaced by "industrialized", I guess. A fireplace is not the same size as power plant furnace. Therefore they do not have de same side effects.
Anyway. I don’t believe in 100% wasteless. Remember Lavoisier in chemistry class?
Lavoisier was a chemist, in chemistry there are always wastes. Whereas in physics it is not quite the same (eg. hydro, tidal, or solar based power plants).
