    We were absolutely not sure how fire really works (low temperature plasma dynamics and so on) when we used it in caves eons ago.

      We also did not build turbines then.

      Also, a campfire is not plasma, so you probably shouldn’t be building any turbines either.

          Very hot flames can contain enough ions / free electrons to be considered a plasma but a wood campfire the likes of which cavemen built, which is what we are discussing here, do not achieve such temperatures. If cavemen wielded acetylene torches then they might have more experience with plasma.

          If you were thinking something simple like “fire is plasma” that is reductive, and the cases where flame is plasma are not the everyday kind. Hence, when I said “a campfire is not plasma” I was being pretty specific. Your reply that ”fire is a low temperature plasma,” as an unqualified blanket statement, is wrong. Go read on it. It’s interesting.

              I may have to yield this point to you as a demonstrated authority on not understanding plasma.
