Submission + - Instapundit Glenn Reynolds with the scoop on Food Deserts

Austrian Anarchy writes: Glenn Reynolds has the story on the current state of food desert affairs: "VIDEO: A Driving Tour of a West Knoxville “Food Desert.”
UPDATE: You know, this kind of verification (or de-verification) of what the government tells us — what the spy satellite guys call “ground truthing” — could be interesting in all sorts of fields." The video he mentions shows the USDA food desert map, with a zoom to a Google map of the same spots, followed by in-car drive-by video of numerous grocers (including Trader Joe's and Target) throughout a "food desert" in a prosperous area of town.

" bacteria growing in it within a week due to the ethanol being a great thriving place for it."

You apparently don't know biology either. In "the real world" alcohol is actually used as an antiseptic (ie a compound which KILLS various microbes) From 12 year old bottles of scotch, to vodka, wine, and even that sterilizing cotton swab the doc uses before a shot, ethanol kills bugs dead.

Maybe you're thinking of diesel fuel or even gasoline - which can host notable bacterial colonies?

Oh yea? Microbial contamination of fuel ethanol fermentations
Ethanol-loving bacteria accelerate cracking of pipeline steels Plus what the guy with the motorcycle upthread is complaining about.

Have fun with it. So many people doing restorations go with upgrades. But yeah, if you are keeping it low RPM and low compression, there's no reason for FI.

Yep, but not exactly "low" compression, at least not as low as the 1972 factory version of that engine. But it will be kept in pump gas compression range, 10:1 11:1 ish I think. Most of my driving, she will be running on the center 2bbl. anyway, the only time I anticipate opening up the outboards is passing on the highway.

The tax issue is with diesel fuel. All gas sold has the road taxes included, even if so.d at marinas. You can, if you are fueling your boat, collect the receipts and submit for a refund of the road taxes.

Marina fuel is usually more expensive because of the significantly higher costs of moving the fuel from the tank up on shore to the tank in the boat.

I guess that might have been the issue, people claiming marina receipt gas that they used in their cars, or something.

If there are any marinas around, you will likely find pure gas.

This is because ethanol in most forms bonds with water easily and will even pull water from the humidity in the air. This isn't good around lakes and with vehicles intended to be on bodies of water.

However, it will likely cost a premium to get. Probably because it is a niche market or perhaps the lack of an additive oxygenate in the fuel which ethanol is supposed to be (as a replacement for MTBE)

Isn't there some stupid tax issue with this? Marina gas is exempt from the highway tax or something? I recall the issue coming up decades ago when a couple of boat owners were talking about it, but I seriously don't know what the answer is today.

The energy density of gasoline is higher than with ethanol, so the more ethanol you add the more you "dilute" the energy contained in a particular volume.

Though the knock resistance is higher because of the lower energy. So if you have a high compression engine that "requires" 91 or higher, and you have a choice of 87 "pure" or ~95 E85, you may see better mileage and performance from the "lower energy" E85.

Going with a six-pack traditional carb setup too because MPFI additional expense on a small block is just not justified.

Unless you are bumping the compression and using parts in your restoration good to 8k+ RPM, in which case FI is required for accuracy and volume (especially accuracy at high volume).

No, I am staying in factory range on this 318, around 6,500 redline. Caming it to deliver the horsepower and tq. at the low end, since I will be using it mostly at 1,500 and below. Plus, radical cams mess with the vacuum too much for the outboard carbs to open and close when they are supposed to, according to the big guy at Hensley and others.

I restored a 75 CB550, had to do the same thing with mixed results. The biggest issue is higher exhaust temps, which I combat by adding top end oil. Works better than going richer on the jets and does not leave the carbon buildup richer jets leave on the piston.

I use Mobile 1 in everything already, but the new exhaust is going to be ceramic coated with thermal lining. New forged pistons/rods, and aluminum heads too. Trying to figure out a way to hide all that cast-in badging on the intake and heads I want to use, since part of the look I want for the engine is "if the factory made a 318 Six-Pack, it would look like this" sort of deal. Yes, I am one of those paint the aluminum to look stock kinda sleeper guys :)

The way the USDA has developed their food desert map leaves few options for solving this problem, at least it leaves few options for getting an area off of their food desert maps. For one thing, if you have an expensive subdivision within the city limits zoned residential, by definition a grocer cannot locate his storefront there and it becomes a food desert because the residents do not have "access" within 1 or even .5 mile of a grocery. If only 500 people within that cen

Consumers can always factor that in if they wish. Other things are factors too, convenience of the station is pretty close to the top. People around where I live who say "they all charge the same price" really don't get out much. Find a different cluster of stations, and you will find a new price, which is not hard to do even in cities of 175,000 people.

but with motorcycles, ethanol has continually given Carbs troubles by promoting gas that gets all sorts of bacteria growing in it within a week due to the ethanol being a great thriving place for it.

I hate ethanol and it ruins motorcycles really quickly :(

Have you tried a fuel drying agent? The bacteria is growing because the ethanol absorbs water and gives it a medium to grow. Straight petrol products do that too, at a lesser extent.

2012 honda insight runs the e10 fine but gets better mileage using 0% ethanol gas from the local marina, ive had to rebuild the fuel system on my 65 datsun van because of the ethanol eating the hoses.

That is why as I restore my 1972 Charger, she is getting ethanol compatible gaskets and lines. Going with a six-pack traditional carb setup too because MPFI additional expense on a small block is just not justified.

From the post above:

I seem to get better mileage with all-gas, but the circumstances haven't been controlled enough to make a good comparison.

The energy density of gasoline is higher than with ethanol, so the more ethanol you add the more you "dilute" the energy contained in a particular volume. One thing the ethanol seems pretty good for is cleaning out your fuel system. If you are in an area where they seasonally increase the ethanol you might want to change that fuel filter a tank or two after the swap. Also, a fuel drying additive is a good idea if you have any ethanol, because that stuff collects water like mad. Keeping the water in solution reduces fuel tank corrosion.
