BTW, I live in Brazil where ethanol from sugarcane is widespread

  Yes, I assume in regions with an ideal climate, sugar cane crops average around 50 tonnes/acre or roughly 125 t/Ha. [Note ^1 - average over all in Brazil this year is 70.5t/Ha] Using this lower average, if the yield averages around 14 ccs (roughly 1/7 sugar) the 70.5 tonnes translates to about 10 tonnes of sugar. Going the ethanol route under ideal conditions would derive around half that weight as ethanol, but ethanol is relatively easy to handle as a fuel source since the petro industry already has much of the infrastructure in place, as well as letting older engines that don't have much use remain in service. (I suspect that older pre fuel injection engines would be fine with 80% ethanol, 20% water.) However since electric cars are now not the stuff of science fiction, it maybe makes more sense to investigate and use sugar to power a fuel cell instead.
