any economic venture such as this requires a holistic analysis, not just strict financial projections. firstly, the sugar cane useage yields very little in the area of job creation, since 100 hectares provides for only 10 jobs. secondly, there is just not enough land to take advantages of economies of scale. i will not get into the myriad of other considerations involved in such a venture, such as energy input versus output, management structures, cane type, monoculture degradation of the soil, etc. sounds nice as a barstool point of conversation. a waste of precious time, otherwise. for the USA to be self sufficient in ethanol, you would need to plant every available acre of arable land in the USA, and Mexico. dump the idea.
