PHOTOSYNTHESIS AS A RESOURCE FOR ENERGY AND MATERIALS* [PDF]

open access: yesPhotochemistry and Photobiology, 1976
Abstract— Photosynthesis, both natural and as a model process, is examined as a possible annually renewable resource for both material and energy. The conversion of carbohydrate from cane, beets and other sources through fermentation alcohol to hydrocarbon may again become economic in the light of improved fermentation technology.
