Newscloud brings us news of a startup called E-Fuel promising to ship a home-brew ethanol plant, the size of a washer-dryer, for under $10,000 by the end of this year. We've had plenty of discussions about $1/gal. fuel — these guys want to let you make it at home. The company says it plans to develop a NAFTA-enabled distribution network for inedible sugar from Mexico at 1/8th the cost of trade-protected sugar, to use as raw material for making ethanol. A renewable energy expert from UC Berkeley is quoted: "There's a lot of hurdles you have to overcome. It's entirely possible that they've done it, but skepticism is a virtue."

Science: Startup Claims to Make $1/Gallon Ethanol 456 comments
gnick writes to mention Wired is reporting that an Illinois startup is claiming they can make ethanol from most any organic material for around $1/gallon. Coskata, backed by General Motors and several other investors, uses a process that is bacteria based instead of some of the other available methods. The bacteria processes organic material that is fed into the reactor and secretes ethanol as a waste product.

$1/Gallon "Green Gasoline" In Sight 740 comments
mattnyc99 writes "We've gotten excited here about the startup that claims it can make $1/gallon ethanol out of anything from trash to tires. But we've also seen how cellulosic ethanol is a better option, and how ethanol demand in general is only adding to the worldwide food crisis. So what about $1/gallon gasoline? NSF-funded researchers at UMass Amherst just completed the first direct conversion from cellulose using a new method of hydrocarbon refining, which they claim can be commercialized within 5-10 years and essentially make fuel out of anything that grows. Quoting: 'We already have the infrastructure in place to distribute liquid fuels. We're using them to power transportation vehicles today, and I think that's what we'll be using in 10 years and in 50 years,' Huber says. 'And if you want a sustainable liquid transportation fuel, biomass is the only way to go.'" The process is running at about 50% efficiency now; the $1/gallon figure is based on getting to 100%.

Besides the inefficiencies of transporting the raw materials, the finished product CANNOT be piped due to the inherent water in the ethanol rusting/corroding the pipes. So, the only means of transportation is truck, train or barge -- fossil fuel transportation systems.

Second point: Trains use (1/5) the fuel of trucks per ton-mile, barges (1/10) and the engines are far easier to convert to biodiesel. Each cylinder in a train engine is something like 2 liters, and there are 12 of them. The engines are tolerant of crap. In fact on EMD locomotives, one never changes the oil, just the oil filter. I agree though, that using fuel to move fuel is not good.
The point of mentioning trains though, is that railroads have to pay HUGE property taxes on the one best solution to their pollution. The railroads would see their property taxes TRIPLE on electrification improvements. That, coupled with high capital costs means that railroads won't touch electrification.
If they did electrify, rail transportation could potentially be carbon-neutral. They merely need to buy the power from a renewable source.

Look at Brazil for an example, here we make Ethanol from sugar-cane.It had virtually no impact on food price or availability, mostly because the culture is concentrated at the north-east region while our grain production is more concentrate on the middle and southern regions.
Also, Ethanol harvested from sugar-cane is a good alternative for lots of developing coutries, because it would give them a valuable commodity to export.
Ethanol would be good for Europe too, because they would have a cheaper alternative to petrol.
But Ethanol is bad for the USA, mostly because you don't get the same level of production from corn, so it's more expensive. And you have to dedicate a bigger slice of land to produce enough to supply the demand for fuel, and this means less space for food.
Also, the North American Petrol industry don't want to see their market taken away.
Ethanol is viable, and it's already a reality here at Brazil. My car can run on both ethanol and gasoline, but since Ethanol is about 30% CHEAPER I almost never put gasoline on it.

A ratio of less than 5:1 results in gradual degradation and stagnation of the economy.

Then you just distill it to concentrate the ethanol. You'd probably have to make two or three passes through the still to get it up to E85 level.
There's a couple of fairly significant problems with this scheme, though. One is the energy that's used to operate the still; where does that come from, how much does it cost? And the other one - and one that'll be very difficult to overcome - is that ethanol is the stuff we drink. Dilute ethanol with distilled water at about 50/50 and you get some so-so vodka. Add this or that flavor and you've got a party.
The BATF isn't going to like this one little bit. Liquor taxes are an important source of revenue; they'll insist that you comply with their bureaucratic regulations if you're going to make any kind of product that contains ethanol.
And if this magic box will produce 170 proof at $2 per gallon - how much of that is going in the car and how much will be going into mixed drinks? Imagine the parties; gallons and gallons of alcohol and more being produced in every neighborhood every day. I suspect the law of unintended consequences is going to kick in on this one...

The time-honored method of turning sugars into ethanol is to ferment the sugars; the yeast culture will excrete ethanol until they perish in their waste products at about 7% ethanol.
Then you just distill it to concentrate the ethanol. You'd probably have to make two or three passes through the still to get it up to E85 level.
Yeast cultures have gone a long way from the days of 7%, especially if you're distilling.
At home, with a modern turbo yeast, you can get ~14% alcohol in 24 hours and 22% alcohol in 5~10 days if you add extra sugar.
Some yeasts ferment cleaner than others, but if you're distilling, you might as well go as hot and as fast as the yeast will tolerate, since the impurities will come out in the fractionating column. With fractional distillation, you should never have to make more than one pass to get 95% alcohol.

What would we do the rest of the year I don't know. And guess what this would do to sugar prices. Also - no more sugar in your food either.
And if the proposition is to use this as an addition to oil-based fuels, well - we are talking less than 1% of total gasoline requirement from entire Mexican crop. This would hardly make a dent in oil consumption, but sure as heck would wreck havoc on the sugar and food markets.

For $10,000 you can convert your gas powered car to be powered by electricity. "A typical conversion, if it is using all new parts, costs between $5,000 and $10,000 (not counting the cost of the donor vehicle or labor). The costs break down like this:
- Batteries - $1,000 to $2,000
- Motor - $1,000 to $2,000
- Controller - $1,000 to $2,000
- Adapter plate - $500 to $1,000
- Other (motors, wiring, switches, etc.) - $500 to $1,000"
The advantage here would be a form of daily transportation with zero-emissions, using a quiet motor that's cheaper to operate per mile (3).References

Block the metabolic conversion with the appropriate enzyme inhibitor (or a competitive substrate like lots of regular ethanol) and you block the toxicity.
