As far I understand, the production of ethanol from corn or sugar crops
needs a lot of energy for the fermentation and distillation of the final
product (half to 2/3 of the total). What about, instead, biomass to liquid,
a dedicated Fischer-Tropsch process for biomass ? Which are the typical
energy inputs in terms of high or low temp heat, electricity or, say,
hydrogen of these kinds of processes? Do they produce only diesel fuel or
can produce gasoline substitute for spark-ignition engines, too?

Just think about how much energy is needed to harvest biomass, transport it and
then grind it up fine enough to use?

As far I understand BTL are not so energy intensive as fermentation
processes (being a combustion process), neither they need any particural
food crops, indeed they can accept any "waste" biomass, no need to harvest
new dedicated plants (particurally, together the development of electric and
plug-in vehicles); moreover, they can use the whole plant and not part of
it, for example the starch for corn ethanol
