Sugar cost & beet versus cane (Score 1)

Last time I noticed, the world trade price for raw sugar was about US$250/tonne (European and USA prices tend to be much higher with protection against excessive importing of cheaper sugar from tropical countries). I can't find what the conversion efficiency to gasoline will be like, but I'd suggest on a mass balance that more than 4 barrels a tonne would be challenging. So how will this be a cheap fuel? Sugar cane has a better yield to sugar beet, not surprising since it is grown in tropical/sub-tropical areas and the plants grow several metres tall compared to a bulbous root under the ground. It also has the advantage of having a byproduct (bagasse) that can be used as a fuel to run the sugar mill. Beet factories require fuel from other sources, which increases the processing cost.
