That's a very valid point here. The general discourse is blured with the misguiding with terms such a "producing energy", when physics clearly show great result

That's a very valid point here. The general discourse is blured with the misguiding with terms such a "producing energy", when physics clearly show great results with the assumption that there is only energy transfer and never any production. At best we can produce a way to capture existing energy and route it where we feel useful.
