Could the US in theory grow enough of what ever this product is to provide all or our fuel energy, including that energy would be required to grow the crop and produce the fuel, anytime in the near future? What about just enough that coupled with our own petroleum resources would it be enough for total independence?
I've read some anecdotal reports that while most e85 hovers in the 103-107 octane range, it behaves like 110-112 when being burned in some applications, apparently due to the cooling effect of the alcohol.
As an update to an earlier post, the stoichiometric rating of e85 is apparently 9.76:1.

Batman,
Checking to see if I am tracking with you.
Is it your theory that because of the higher octane rating, you can use a much higer compression ratio, making more power, thus being able to use say taller gearing to make up for the added fuel that is needed because of the decreased A/F ratio?
If that is the case, then couldn't you use 110 gasoline, with the same changes to utilize the octane to its full potential and get better mileage with the gasoline, because of the increased A/F ratio?
I have nothing against E85, just trying to learn about these alternate fuels, and understand what the real impact/benefit is.
With my experience with methanol, fuel efficiency has never been a thought, as with our application, we would be measuring it in GPM's (gallons per mile
).
The Joker....

Obviously 100+ octane gasoline is going to produce even more power than e85 at those high compession ratios, but 100+ octane gas is only available as leaded aviation fuel and is quite expensive. In a lot of areas, e85 is cheaper than 87 octane regular.
There's a lot I don't know about this, and so far for me it's all theoretical. I've been doing a lot of research lately, though, as I've been seriously considering taking advantage of the ready availability of e85 in this area.
