Looks interesting, but as yet does not look commercially viable. Looking at their site, they speak of their "mullite" alternative to precious metals, but none of their data talks about it. The only graph does a comparison on precious metal AU/PT ratios, but does not talk about Mullite at all?
No mention of any test applications where emissions were reduced, nor talk of cost reductions vs precious metals. Some talk about reducing PT usage in favor of AU, but at $1600 an ounce, how much of a savings on a typical catalyst?
I'd galdly try one out on my Passat wagon, and report any emissions reductions at test time...
