From the article: "The 97 percent efficiency is the highest reported, according to the researchers. There is one catch -- only five percent of the sun's energy is ultraviolet light. "

In less-biased engineering terms, we would say that this process for converting sunlight to an alternate form of energy is 5% efficient. But why let realistic calculations get in the way of a good story.

The claim out of Carthage Missouri is that they have their process at 85% efficiency, meaning they can "refine" turkey guts into oil and end up with a "net plus". If they can engineer this down, with a discreet input (manure, municipal water-waste, medical/slaughterhouse waste) their exists the possibility of colocating next to diesel power plants and generating electricity.

Actually, it's 97% * 5% = 4.9% efficient.... ;-)
