Is it excessive? It certainly doesn't seem to be BS. It's published in a reputable journal (which doesn't make it true). It discusses several of the questions raised by Animats directly (though I wouldn't say it answers them conclusively). I do agree that the university press release isn't going to critically evaluate the work of its own researchers. That's too bad, perhaps, but it hardly renders the original result uninteresting. Artificial photosynthesis may be old, but the advances in this work appear aimed at overcoming precisely the problems Animats raised, like catalyst preservation and efficiency. Put another way, just because a university gushes about the work of its faculty doesn't mean the faculty's work is crap.
