Is Gasoline A Renewable Resource
Thursday, August 11th, 2011
why can’t alcohol be a replacement for gasoline?
I figure pure ethanol would be easy enough to use as fuel. And of course, it’s a Renewable Resource. Grow some grapes, I guess, let them rot, pump them in the tank, take off. Not really, but still.
Ethanol IS used as a motor fuel, in Brazil.
70% of the cars sold in Brazil are flex-fuel and can use either gasoline or ethanol.
A few things about ethanol.
Being hydroscopic, ethanol readily absorbs water, so plain steel fuel lines and other fuel system components can easily rust with 100% ethanol. You would need to upgrade those parts to aluminum or stainless steel.
Another issue is swelling of some types of gaskets or O-rings, from the ethanol. These may need to be replaced.
Finally, ethanol contains less energy per gallon of fuel. E85 (85% ethanol / 85% gasoline) provides only 70% of the energy content of 100% gasoline, meaning that you will need 14.4 gallons of E15 to drive the same distance as 10 gallons of gasoline. A higher ethanol content will contain even less energy.
