For our purposes, just consider the ratio of 115/75.7 to see that a gallon of gasoline has about 52 percent more energy per gallon than ethanol does.

Or looking at it the other way, ethanol has about 66 percent as much chemical energy as the same volume of gasoline.

Assuming it could burn either just as well, a car would go 52 percent further on a tankful of gasoline than it would on a tankful of ethanol or 66 percent as far on a tank of ethanol as it would on a tank of gasoline.

Ten percent ethanol blend should yield 0.9xg plus 0.1(gx0.66) or 0.966 times as far as pure gasoline. Ethanol isn’t added to help mileage but to reduce air polution without creating water pollution in case of a spill.

If ethanol costs 66 percent as much as gasoline, you pay the same price per mile driven using ethanol or gasoline.

David keeping it simple

Thanks for the info. I’m glad the engine thing has been sorted out since we use 10% ethanol now. Anyway, I still question the validity of using ethanol. I don’t know the new numbers but I do know that, along with ethanol requiring more fuel to prduce than it generates as you state, it dropps gas mileage. If the numbers haven’t changed significantly in the last few years then sure for a given gallon of gas you are emmiting less harmful particles but the number of gallons you now have to use probably offsets any savings. Anyway…

Hopefully McDavid can get past all the crap and build the nuclear plant. It really is the best source of baseload energy for the US.

I watch a lot of the science, history and health channels.

That’s a classic..

Power to the ppl!

Fire them all, everytime you go to the poles.”

Nobody runs all vehicles on corn. In fact, corn uses more energy than it produces. Sugarcane based ethanol, however, produces more fuel than it uses and is popular in Brazil, never heard of Chile using it, though. Probably means I am behind on events.

If you voted against everybody at the polls, that would be very much like not going in the first place.Bbetter to vote for those you like, against those you dislike.

Power to the people is an excellent thought. Get the people safe, reliable power not dependent on international trade, alliances with dictators, funding to terrorists or kick-backs to the corn state with the first primaries or back-room deals in Congress.

That would be nuclear power, it seems. President Obama is right in pushing for more of it and those who oppose him are just doing it because he is from Hawaii.

REGARDING: the claim that ethanol harms engines: It did harm natural rubber fuel lines back when they were used but does not hurt synthetic rubber lines. It also would cause stopped up fuel filters when first put in tanks with years of build-up because it would loosen it and run it in the fuel lines. Now that nearly all gasoline has about ten percent ethanol, the problem is behind.

University of Florida has system in trials which converts all cellulosic materials into ethanol so pulp wooders could be providing fuel for your car in the near future. That way you don’t have to use food plants or raise the price of sugar for my candy.

Methanol, unlike ethanol, does cause engine problems because it dissolves or reacts with aluminum and cars have plenty of aluminum parts in contact with fuel. It’s a shame too, because we have an abundant supply of methane which could be converted to methanol and provide domestic transportation fuel.

On the other hand, methane is a good fuel when compressed and would be particularly sweet in a hybrid system. That would extend its range greatly. It’s safer than gasoline.

David wanting a nuclear car so nobddy will dare rear-end me

DAVID HUIE GREEN

Everyone has enough ground to plant a garden and feed
themselves if they have to.
However, Clean air is another thing.

Corn is just one example. My point was this huge monstrosity
is junk. Their are BETTER ways. More up to date ways to
handle this problem.

I myself have a hybrid. No! I don’t always drive it. But some months
I drive it most. It depends on my mood, or whatever else is going on.

It is still my opinion we need to go GREEN!
