[Peakoil] Ethanol on 666 this morning

[Keith Thomas]

Broadly speaking, ethanol requires an energy input from all sources,  
including externalities, of about 10 times the energy in the starch  
that is harvested. From the harvest to the point where the ethanol fuel  
arrives in the car's fuel tank, a further factor of ten is lost. The  
there is the 70% (approximately) efficiency of ethanol-burning engines.  
So, we'll take 100 units of energy to produce 0.7% units of energy  
propelling a car.

My trike is looking better by the day:
