E15

Basically no farm animals can digest it,...

I can't digest it either.

Leave it to the EPA to further support a product that is only available because our tax dollars are used to compensate the value that is actually lost in its production.

Growing the corn for ethanol is basically raping the Earth anyways. The rate at which crops are grown and harvested to keep up with the demand degrades the soil & nutrients. Never mind the fact that it's causing food scarcity and huge fluctuation in food prices across the globe. I think the figure is something like 60% of all U.S. grown corn goes towards fuel rather than food.

That's been the norm for several years now.

Are you confusing e85 and e15? e85 is 855 ethanol, where e15 is only 15% ethanol. E10 of course is 10% ethanol.

As I read the web site I understood it to mean 85% E. What is butanol?

Alcohol made from butane instead of ethane. It has 4 carbon atoms instead of 2. It still has the OH hanging on the end. Probably equally detrimental to elastomers ( I would have to confirm ) and equally thirsty for water. It would have a higher adiabatic flame temperature and heating value than ethanol...but still not as high as good ol' gasoline.

Thankfully the only pure gas is on the way to my launch. It's 89 octane and expensive. They refer to it as "boat" gas

A few years ago, the stations near the luanches of several nearby lakes had boat gas but I have not been past there in a while to know if they still do.

Wow - that was a bad/long sentance.

e85 is 85 percent ethanol.

I think I typed a 5 without the shift key, so it wasn't a percent sign, but rather a 5.

Butanol has a lot of very good properties, but one negative is that is has issues at lower temps. That's not a problem in a any recreational boat.


Here is some info on butanol.

The E85B sounds very interesting. It is 85% ethanol, and 15% butanol and acts more like straight up gas than ethanol does. it's 100% biofuel too.

The other interesting thing about butanol is that it can be made in the same way that ethanol is,so it doesn't require a costly machinery change to produce it.
