Fears that spending would go far beyond profit did not come true: after a two- to three-year start-up period with higher costs and less crops, the crops later consistently yielded high yields of 3, 500 liters of ethanol per hectare. Energetically particularly favorable suggests here that the woody remains of the plant, which are not used for sugar production, which can fuel the necessary to produce ethanol biorefineries alone and no additional energy supply is needed. There is even electricity left for sale in the market.
Not only compared to gasoline, but also to other suppliers of biofuel, the sweet grass cuts well: Since it is perennial, rarely has seed to be procured and applied, unlike corn, canola or grain. Also, rodent millet fixes more carbon dioxide in the soil than this and thus has a much better greenhouse gas balance. With extended cultivation and careful breeding, the yield of the millet millet could easily be increased by 20 to 30 percent, the agronomists believe. In a few years, it could cover nearly one-third of US fuel needs.Marty Schmer (Institute of Agriculture, University of Nebraska, Lincoln) et al .: PNAS, Volume 105, p. 464 ddp / science.de?
