I read the article and the answers certainly weren't clear to me. '20x cheaper than some other catalysts' what does that mean exactly? 'special fluid keeps catalyst sites clean' does it get used up in the process? Is the fluid expensive and hard to manufacture? The devil is in the detail here. How exactly does this compare to other state of the art similar approaches? 10x cheaper? 2x cheaper? on par? I think it's pretty valid to argue the article is doing some vague hand waving without actually saying if this is meaningfully better than other approaches.
