[Gasification] coal coocking

[kenn johnsen]

Nils.

Just a couple of question, are there any money in it for the farmers,  
or is the 50 €T just the cost of transportation of the straw.
Is the 0,27 €L the total cost of production, what means included  
production profit.
It seem to me that the process is fully competitive, if it is without  
Gov. subsidies ?? is that the case ?? when is it competitive, at $ 60 -  
50 - 40 a gallon, of oil.
