Sir Sam

INCORRECT! KKs are also 5 x 4.5, just like the MK's are, as is noted in the Wheel guide.

Thanks for the love......thats what the wheels guide is there for.

I'd really like to have a CJ8 with one of those tops....always loved that "world top".

Like many people I fear and loathe change, which is why we all have 20+ year old jeeps.

Just keep in mind that most of the photos you see on allpar are not jeep concept photos, but rather some guy sitting behind a computer with photoshop open. These photos we are seeing are photoshops of a current vehicle with what someone thinks could be a possible styling ques, they are not anything that actually might make it into production because they are not official.

Fruit trees just don't produce fruit sugar to make an appreciable dent. Sugar beets would be one of the better sources for you. Under ideal farm conditions sugar beets will produce about 40 tons/acre/year. Thats with petrochemical fertilzers and pesticides, lets assume you have neither since after all we are talking about the end of the world as we know it. Second, lets assume you are not a professional farmer who knows exactly how to farm to get the best yield. I'm going to round off those factors and say under the best conditions you get a 25 ton/acre/year yield. Sugar beets typically have a sugar content around 17%, the problem comes in efficiently extracting the sugar from the beets. If you were just to mash them up and ferment them you would not get all the sugar out in suspension where the yeast can eat away at it. One such method to extract sugar is to use alcohol, sugar is highly soluble in alcohol, so mash your beets up and run the mash through an alcohol wash. Run the sugar alcohol wash through some sort of still (a passive solar condensation still would be ideal here so you can reuse that alcohol. But again, there will be loose here as well. I suspect you will not get the full 17% as under ideal conditions, in fact I think you will be lucky to hit 10%. Getting higher yields is the sort of thing companies like Cargill pay PHd Chemists and Engineers 100k + a year salaries for. So far we have 25 tons/acre, 3 acres, 10% yield of sugar. That gives us about 15000 pounds of sugar........thats an appreciable amount of sugar, but we still need to convert that to alcohol. Wild yeasts will have a very low yield, bakers yeast are better, and distillers yeast is best, however without a continual supply of fresh yeast it will be difficult to keep high yeilds up. So we will assume under ideal conditions you can keep a bakers strain of yeast propagated. Now the next issue you will run into is having the proper nutrients for a high yield wash, with a good source of phospate(DAP etc) you will run into a wall real quick. All said and done without proper nutrient washes you will hit about 9-10% yield at the highest. Now what that means is that you will have a low alcohol wash that is going to take more energy to distill than a higher % wash. The Enthalpy of vaporization for ethanol is 0.841 KJ/gram. The Enthalpy of vaporization for water is 2.23 kJ/gram. The energy density of ethanol is 26.8 kJ/gram At a 10% wash: 2.23 * .90 + .841 * .10 = 2.1 kJ/gram 2.1/26.8 = 8% of your product that will need to be burned to produced the heat required to distill your product at the bare minimum. Thats not counting any other thermal efficiency losses.....even a 20% figure is realistic and damm near as good as you could get. so you have 15,000 lbs of sugar.....you ferment that, make a bunch of low % wash, and then distill that. Assume you are not doing a vacuum distillation you are going to hit about 95% output with a reflux still, that equates to about 1040 gallons of 95% alcohol. Assuming a 20% efficacy loss you have 832 gallons of fuel. Now compare to gasoline, gasoline is about 48.1 kJ/g compared to 26.8 kJ/gram. That means the pure alcohol has 55% less energy than non ethanol gasoline. Lets look at it another way, that 832 gallons of pure alcohol is more like 458 gallons of gasoline. Thats not even looking at how much of that fuel you will need to use to plant/grow/harvest and transport the sugar beets to make the fuel. You need lots of sugar. Source: ME with a background in alternative fuels and a distiller.

It takes lots of sugar to make alcohol...........LOTS Lucky for us, sugar is not too hard to acquire. its in every fruit we eat, vegetables, grains, etc. Did I mention lots of sugar? Not sure how you plan to harvest enough sugar to make any appreciable amounts of alcohol without using a bunch of fuel in the first place.

What control arms are you running?

It takes lots of sugar to make alcohol...........LOTS

Maybe someday I will get back into fishing......someday..... Thing is....I just don't like eating trout.....too many damn bones. Catfish though.....get a good freshwater river cat.....mmmm

You know...I'm still working on my diesel swap....

Thanks for looking.

Seems to happen with every model, ZJ, KJ, WK, JK etc etc

Clearly this is an early test mule, the body stampings(IE main chassis) looks finalized, but I would bet dollars to donuts the front end was intentionally obscured with that weird half @$$ grill for a reason. It's entirely possible this test mule was meant for something like emissions validation tests....hence why it is not a production vehicle. It had to be on the road for some miles, but they didn't want the final aesthetics revealed yet.

Couple of youtube videos online, first one of just a bunch of general thermal stuff, and a second of old faithful.

Was on my way to south Texas for a funeral.

Thanks for looking. Unfortunately it was so smokey you could not see the Tetons from the highway. We spent very little time there this trip consequently.

He doesn't need to worry, I have done it dozens of times. The airbag computer does not need to be replaced.

The airbag computer DOES NOT need to be replaced on the XJ. Just hookup new airbags, very often the clockspring squib will melt to the airbag, if it does you need to replace the clockspring. I don't think the Xj airbag computer stores the VIN to do a vin check against the ECM, but it might be worth putting back in the original airbag computer to make sure there is not vin mismatch problems.

Oh man, it was so nice in boulder after they passed the no smoking laws. I was so happy when that happened.

So who owns the other diesel MJ?

That poor Jeep. Thats what i said. But a 4wd 39 ford will be interesting lol Ya, and it could be interesting on a cheap ford frame that is plentiful.
