Producing fuels from photosynthesis is insane - unless you can violate the laws of thermodynamics at will on a huge scale. Even Brazil with free land from chopping jungle, essentially free labor, and Third World minimal agriculture fuel-ethanoled itself into national bankruptcy.

Fuel ethanol bottom line
The most efficient uses of bio fuel burn corn in a stove designed to burn wood pellets. Heating with corn at $2.50 a bushel is the same as using $(US)0.64/gallon propane. The best deal is to burn the anhydrous ammonia fertilizer and not bother planting the corn. You must have a way to condense the exhaust and store the nitric acid for resale, and you have to keep it burning so it produces nitric acid and not merely nitrogen oxides. That one makes money. Barely."
