The only caveat is there are no positive net-energy sugar feedstocks available in meaningful, quantity that can be grown in the temperate/subtropical climates of the US. Brazil's use of sugar cane is a geographic aberration that has no direct relevance to the US energy plans unless we choose to make Brazil our primary source of sugar. Other sources of sugar like cellolosic biomass are very iffy still. If using Brazilian sugar was economically unacceptable for colas in the 1980 I don't see how it can suddenly become more acceptable than Middle Eastern oil today. Nonetheless, this is an interesting development that could someday fit into the mix of yet-to-be-developed technologies. I'm still professionally partial to weedy-biodiesel though the best candidates are unlike to be taken serious because of their politically incorrect "dual-uses". The next best is still solar in its various forms. There’s a lot of potential with any biomass-based fuel discovery.
