On the other hand, further research is needed to fully understand new technology's advantages and evaluate if it can be scaled up efficiently for the production of biofuels or other purposes. One of the first concerns to be answered will be whether or not the energy cost of making olefins is too high to be practicable on an industrial scale. Another concern is how much energy is used in the production of olefins.

Increasing output is also in the best interest of scientists. About 8 olefin molecules are needed to produce 100 glucose, Wang calculates. To improve this ratio, the researcher is hoping to encourage E. coli to produce more 3-hydroxy fatty acid per gram of glucose consumed.

Dear @jsalvage, Your article is interesting!
However, the current production cost of biofuel is more expensive than that of petroleum fuel. In particular, the problem of carbon emission through sugar farming will cause environmental problems.
