[Gasification] Cellulosic Ethanol a dead end

Dear All:

If you think converting the 70% starch in corn into sugar and then into 
ethanol is inefficient, (MAYBE 35% more energy out than in) just try 
stripping the lignin out of cellulosic materials as a hurdle.  Dozens of 
companies (since the first in 1918) have claimed to have the process 
"now commercial", sold stock, then quietly tiptoed away.  Mother Nature 
designed starch to be converted to sugar.  She designed cellulose NOT to 
be converted into sugar.  Given enough subsidies it can be commercial 
today, but so could many other processes with higher payback.

Now we propose in Bella Vista, Corrientes province in Argentine to Major Mario Haberle use poplar and willows to produce cell ethanol. More than fifty years in these county was operated and wood ethanol pant ia a place named "Destino".
