Not just refining the catalyst, but all the energy inputs required to make the whole "free energy generator" come into existence. The manufacturing process, not just mining the raw materials. You have to look at the total energy cost to determine if this energy generator does in fact generate energy or not. Most of the "green energy sources" do not generate any net energy, they are net energy losers once you account for the (energy)costs of producing them. How many kwh of energy does it take to make one, how many kwh does one of them output over it's lifetime? This is always a disfavorable ratio for clean energy as of today. I guess this concept is either incomprehensible, or just plain uninteresting.
