> Does the catalyst get used up, or crud up with contaminants, and if so, how fast? What limits the life of the system? What are the costs like? (Excessive catalyst cost has been a problem.)
If you had actually read the whole article before commenting you would know the answer to these questions. Your questions about efficiency are however valid.
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.
I agree with your skepticism but even if the article included more stats there would still be many questions. The only way to prove conclusively that this is a viable method would be to produce it at scale.
