Ethanol is just Ethyl Alcohol, or more commonly referred to as "Moonshine"
One of the classes in my school (BSAA) is making E100, and I think they might Denature it for the use as a fuel (and so you can't really drink it...) But I'm pretty sure E85 isn't Pure ethanol, as its 15 percent gasoline, and E100 is used as fuel today. just not good in engines not built for it.

I guess I wasn't clear. I was saying that E85 was one alternative, and E100 was another alternative. I was also adding as an aside that you can't actually have 100% ethanol, because it is voraciously hygroscopic. (Ever watched an open bottle of Everclear? It gets more full on its own--freaky!! Supposedly it can overflow on its own, too, but we never let it last that long.
)
The "denatured" stuff has benzine and lots of other lovely toxic chemicals in it, so it isn't quite 100% either. And it will still absorb water from the air...
You can get pretty close to 100% ethanol in a lab, but once you put it in anything vented to the atmosphere, it will quickly get (at least a bit!) diluted.
