Some info on ethanol as a fuel: http://en.wikipedia.org/wiki/Ethanol#As_a_fuel
Hydrogen as a fuel is a pipe dream. Most of the earths hydrogen is going to be in a chemically bonded state. H20 is readily available, however it is very stable. We are putting way more energy into the seperation of hydrogen than we get out of burning it.
There is no perfect solution including gasoline, etc. Had we chosen to go with ethanol 100 years ago, we would have tweaked the efficiency of the production process by now ans possibly had smaller, high compression or boosted engines to help make up somewhat for the lower overall energy content of the fuel.

It's a small gas station in Perry, Exit 135 I think. Stop in and try a tank. See if you like it or not. I did. My truck ran VERY smooth and much more quiet. It's usually $.30-$.35 a gallon cheaper than regular. This weekend it was $2.03/gallon or so....

E-85 contains less thermal energy than gasoline. It has been demonstrated to reduce power and mileage, not increase it.
It is NOT 105 octane. Get you figures right, In fact higher octane requires higher compression to perform. Flex fuel vehicles typically run lower compression.
Duh
You're making up stuff.

You pass and electric curreet through water to seperate hydrogen from the oxygen.
The process of using the PEM system is inefficeint compared to its actual output but there are other systems currently in use.
If it is such a pipe dream then why has the us government (the airforce) awarded fuell cell development to mellineum cell technology that currently holds the patent for hydrogen on demand?
Here, go educate your self.
Do you work for an oil company by chance?

dont use it, less ya have to.
i used 1 full tank, i lost at least 3-5 miles per gal.
and yes you can feel a difference, it felt like it had a tuner on it and the response was better.
My truck ? doubt it.
the reason i say dont use it, my truck still hasnt returned to the mpg i got before usin it and ive already refilled with reg 87 4 or 5 times .
havent really had highway miles since usin it, im going on 1000 mile trip friday hoping maybe to see an increase in mpg. also added siso catback since then.
i dont know bout 105 octane but it is higher.
