What method of calculating efficiency are they using? AFAIK, there is no
natural occurence of chlorophyll based photosynthesis that exceeds 3%
efficiency, and only a few specifically bred and engineered plants that
go as high as 5% efficiency, which I had thought was the theoretical
limit for chlorophyll based energy conversion.
