SwiftFuel Alternative To Alternative Fuels

TheDawgLives writes "PBS has an article by Bob Cringely about the best route to end our dependence on oil and reduce our greenhouse gas emissions. Instead of replacing all our expensive cars with even more expensive hybrids or electric cars, his suggestion is to use a cheap drop-in replacement for gasoline called Swift Fuel. It is derived from Ethanol, but doesn't require any modification to older cars to prevent corrosion. It can be mixed with gasoline in any amount and can even be distributed using the same network as gasoline, including being pumped in the same pipes and shipped in the same trucks. It is truly a drop-in replacement for gas, and it is real. It is being tested by the FAA for certification in propeller aircraft. It also happens to be about $2 a gallon cheaper than gasoline."

Re:

You still need land to grow it on, which might otherwise be used for growing food.

Re:Food prices

[Mr2001]

It's not the same land or farming resources, though. Switchgrass grows on a wider variety of soil and climate, meaning it can be grown in places where you couldn't grow food crops, and doesn't require much seeding or fertilizer.

Re:Food prices

[sleigher]

Your right that it can be grown on land that is not used for food and grow very well there. I think the problem is that the people who do grow food might stand to make more money growing switchgrass so then the land for food will be used anyways. I know if I was a farmer and had a chance to make more money growing a weed I would be all over it. I might be wrong in that. It might not make them more money it is just the first thing that popped in my mind.

Re:Food prices

[MacDork]

Plowing up new land creates *lots* of CO2 via soil oxidation too, and quite possibly at a faster rate than the fossil fuels they are "replacing." And since oil is a fungible commodity, the oil you "replaced" will simply be sold off and burned by someone else... Biofuels just make oil a little cheaper than it would otherwise be by decreasing demand ever so slightly. So, it's quite likely that the biofuel initiative is actually make the problem a lot worse. The biofuel initiative is also creating a giant dead zone in the gulf of Mexico due to fertilizer runoff. But don't try to tell any of this to the cult of global warming. They don't like facts interfering in their religion.

Re:Wait wait wait

'Progressives' always oppose progress if they think it benefits the capitalists more than the workers. Even when the workers still come out vastly ahead, just not as much ahead. And to head off the incoming replies, the median income in the US adjusted for inflation is seven times what it was a century ago, and several orders of magnitude above pre-industrial revolution levels (or for that matter, Brazil's current median income). So yes, industrialisation made everyone better off, even though all those farm laborers lost their jobs.

Re:Wait wait wait

[Anonymous Coward]

"So yes, industrialisation made everyone better off, even though all those farm laborers lost their jobs." So those farmers were better off because they had to uproot their lives and move to the city? They had to go through emotional issues of having the ground swept from underneath them? I think they would not have been so quick to praise the industrial revolution. The industrial revolution merely widened the gap between the "haves" and "have nots".

I think we are fooling ourselves if we think things are as rosie as ever. I remember when I was a kid my mother didn't have to work and my father earned a slightly better than average wage. The house we lived in was brand new, in a new estate on the shores of the largest saltwater lake in the southern hemisphere. The house cost my father 3 times his yearly wage.

I am at roughly the same age now, I have a new but fairly average house in a new estate and I earn about double the mean wage. My house is over 6 times my yearly wage. Are we really better off? Yes we have more gadgets but that is not what is best in life. We have been fooled into being hooked on consumerism.

Re:Wait wait wait

[Xenogyst]

"So yes, industrialisation made everyone better off"

Some of that is because we just changed where our poor are. The minimum wage in the Guangdong province, China (2004) is about $50-100 dollars a month, assuming 40 hours a weeks, is about $0.63-0.31 an hour. Which is about 12% of the current US minimum wage; roughly 8 times less.

The 3rd/2nd world is our real labor class.

Re:Wait wait wait

[ArcherB]

There is one line in this entire post that is very telling:

The industrial revolution merely widened the gap between the "haves" and "have nots".

So, it doesn't matter that the "have not" have MORE than they did before? This AC is pissed because someone increased the amount they have MORE than others, even though everyone ended up with more than they started? Are we so afraid that someone may have more than we do that we will accept poverty as long as there are no winners? What kind of crap is that?!!?

I'm reminded of an experiment someone did a while back (don't care to find the link), where people were allowed to play a gambling game where you could see you winnings and everyone else's. The game was rigged of course and set up so that the player would win some, but could also see that other people won less or even lost and some people won more. At the end of the game, they were given the option to reduce the winnings of the top winners and give it back to the "house", but it would cost the player a smaller percentage of their winnings. An overwhelming percentage of people (75% or something) chose to reduce the winnings of the top winners, even though it did not benefit them at all, and even actually cost them some of their own winnings. Maybe it's human nature to want poverty over prosperity as long as everyone suffers equally.

Re:Wait wait wait

[ArcherB]

Found a reference to the experiment I was talking about above... and forgive me if this seems OT, but there is a point to be made here. People suffer from envy. I feel this is what has led to our reluctance to drill for oil, for example. I believe that many environmentalists are afraid that someone may make money off of it. Before Global Warming, drilling was banned in ANWR. The excuse given was that it may harm the porcupine caribou, as the area to be drilled was in the path of their annual mating migration. It didn't matter that the porcupine caribou had been actually doing better since starting another area of drilling in Prudhoe Bay, along the same migration path. Which leads me to wonder, if not because of the environmental concerns they were citing, then why the resistance?
Here [psu.edu]may be an explanation (it is the study I mentioned in the post above... and PDF warning):

We design an experiment where subjects can reduce (âoeburnâ) other subjectsâ(TM) Money. Those who burn the money of others have to give up some of their own cash. Despite this cost, and contrary to the assumptions of economics textbooks, the majority of our subjects choose to destroy at least part of othersâ(TM) money holdings. We vary experimentally the amount that subjects have to pay to reduce other peopleâ(TM)s cash. The implied price elasticity of burning is calculated; it is mostly less than unity. There is a strong correlation between wealth, or rank, and the amounts by which subjects are burnt. In making their decisions, many burners, especially disadvantaged ones, seem to care about whether another person âdeservesâ(TM) the money he has. Desert is not simply a matter of relative payoff.

To bring this back on topic, I fear that the REAL motivation behind some (not all) of th environmental concerns are part of this. How often do you hear the argument that drilling for new oil would "line the pockets of big oil CEO's"? So what? Why do I care if some big oil CEO if it will save me and everyone else $0.25 a gallon? I still end up ahead! What difference does it make if someone else ends up further ahead than I do? I understand that there may be legitimate environmental concerns, then why bring up how much money someone may make?

Anyway, the GP post is upset that even though workers will be better off, and environmental concerns are addressed, the "haves" will do better than everyone else.

'Progressives" inherently back progress. Throughout the past century progressives have been fighting to bring social justice, equality, and higher standards of living to people who were being exploited without restriction by large businesses and the rich.
The increase in American's standard of living is a testament to the labor movement, the women's right's movement, and the civil rights movement, all of which were part of the progressive movement. Before the progressive movement started, the benefits of industrialization were enjoyed only by a very small minority, the super-wealthy capitalists. Progressives spread these to the workers.

Re:Actually you are both quite wrong.

Heh, you mention Peak Oil then in the same breath betray your ignorance as to what it is.

Peak Oil is _not_ "that stuff running out". It is the production of oil reaching a plateau and then going into decline. The peak of a mountain doesn't happen when you reach the valley, it happens when you've got to the top and can't go higher.

Consider this - since 2005 oil production has been on a bumpy plateau with a slight downward trend. There's tons of publicly available data you can research to confirm this. In the meantime worldwide demand continues to go up - where's your magical creation of new oil via supply and demand? Oh yes, Bakken. I'll believe that one when its up & running and producing a few million barrels a day.

You should also realise that the USA's oil production peaked in 1973 - its been all downhill ever since. Even opening up Alaska didn't reverse the decline for long. North Sea peaked in 2000 and its plummeting now. Mexico's Cantarell field is doing the same. Perhaps you should clear your head of the economic "demand will create supply" nonsense and wake up to the geological realities of living on a finite planet with finite resources. Have you checked out the EIA's reports on US inventory levels lately?

Yes it won't run out for ages, probably not in our lifetime. I wouldn't say the same for the chances of being able to fill up at your local service station though.

Re:Actually you are both quite wrong.

[sumdumass]

The problem with peak oil predictions is that it never takes into account for more efficient production advances. You can reverse the peak trends with technology and innovation.

Peak oil doesn't mean that there is less and less oil, but that the cost of getting to it gets more and more expensive and at some point we end up producing as much as we can. Well, with technology innovations and advances, that peak can be moved to higher levels of production until a point where we actually run out. Canada is pulling bituminous oils for sand which was unheard of or highly impractical 20 years ago. And this totally negates the fact that we can make the fuels produced by oil from coal which means that peak oil is mitigated even more.

The US is still the number 3 oil producer in the world behind Saudi Arabia and Russia. We have fields not in production, one of which China has got a lease from Cuba on off the coast of Florida. New types of drilling technology and and processing has allowed us to tap into fields once thought to have been out of reach or too costly to use. Peak oil is a red herring of sorts.

Re:

[Eivind]

Is true offcourse. But it's also true that medium-term higher prices will lead to lower demand /AND/ higher production, there's a sort of equilibrium here.

There are oil-fields that can be profitably produced from at $130/barrel which wouldn't be profitable at $100/barrel. And so on.

But sure, the main idea, that once the easiest-to-get oil is used up, prices WILL rise is sound. The only question is how soon and how dramatic an increase. The current price is already pretty high, even when you include the fact

Re:Actually you are both quite wrong.

[Alioth]

The significant thing isn't a reduction in the amount of oil that can be produced, it's the reduction in cheap oil that can be produced. Only the cheap oil has to run out for the US to be in a severe world of economic hurt.

Re:Actually you are both quite wrong.

[misanthrope101]

The problem with peak oil predictions is that it never takes into account for more efficient production advances.

A sphere of finite volume can hold only a finite amount of oil. No matter how efficient or high-tech your extraction, finite is finite, unless you're using nanotechnology to make oil out of other stuff. Eventually we will run out, though I concede that technically there might be 1.5 cups squirreled away here and there in the crust.

Putting money into increasing efficiency of extraction (and even consumption, like the Prius) only extending the life of the oil companies; long-term, we need to put money into alternatives.

Re:Actually you are both quite wrong.

[smellsofbikes]

>Yes it won't run out for ages, probably not in our lifetime. I wouldn't say the same for the chances of being able to fill up at your local service station though.

My coworker did some research on this over the last week, using data from the Department of Energy website. The stuff he printed out says, pretty clearly, that if we continue using oil at the same rate we are currently using it -- that is, not increasing usage -- the United States would use up its entire domestic supply in three years, and the world would use up its entire available supply in 38 years. Note this is not the amount of proven crude oil: this is the amount of oil extractable from crude oil, oil shale, and currently-existing technology for oil extraction from coal. That's *everything*, all the oil there is, and it'll be gone in under 40 years.

I'm trying to find a mistake in the Department of Energy's numbers, but haven't yet.

Not what parent said; if we don't burn a barrel of oil because we have Magic Fairy Dust (tm), that barrel will just get burned by someone else. At least for the foreseeable future.

And "global cap-and-trade"? Are you kidding? Good luck getting every nation in the world to agree to that system. Good luck getting just China to agree to that system. Good luck getting everyone bound by that system to stop bickering over what their caps should be. And good luck having such a system function as it's actually intended to.

Getting the entire world to agree on a complicated system simultaneously is not a good way to solve world problems. Even if that problem would actually be solved by them doing so. The US has made greater progress on its would-be Kyoto goals than any Kyoto nation - and we didn't even sign the thing.

Now, biofuel is great and whatnot - biofuel and politics have killed a large chunk of the world economy. We subsidize corn ethanol to make the corn belt farmers happy. In the meantime, we have a huge tariff on imported ethanol - we can't buy alternative fuels from Brazil, for example, but we can buy crude oil from the Middle East. The result is a lot of corn diverted for ethanol production.

All this legislated corn-ethanol nonsense raises the price of corn - that's a side effect of doubling demand for it overnight. So, of course, some food prices go up too, but that's just for starters. The prices of other grains rise as well - they're "substitute goods", things people will use instead of the now-prices corn if they can. With the costs of every grain rising, livestock feed becomes more expensive, meaning practically everything you buy in a grocery store is more expensive. Meats, soda (corn syrup, remember) - all of it rising in price.

But it doesn't stop at just food, either. Soap is made in part from waste fats from slaughtered animals. As it becomes more expensive to feed livestock, even something as simple as soap becomes more expensive. We in America can generally deal with the rising food costs, but our Big Ag special-interest political games in the name of the "environment" come at the expense of the rest of the world.

Biofuel is great... If it happens on its own, and not when huge tracts of our economy are forcibly shifted so politicians can win the farm vote.

Just a note, the switch grass, one it is established, doesn't need tilled or anything. It just needs harvested so any Co2 production from it would be a one time thing for the most part.

No till usually doesn't produce the same yields when current crops of going with 40 and 50,000 populations. On some fields it will but in practice, you will find that it doesn't.

Re:Food prices

[hedwards]

And that's been seen before. It's the paradox of efficiency.

Say we're only using domestic fuel and none can be exported. Yes, that's not realistic, but it makes things less complicated.

As fuel efficiency is raised, the demand for oil dips, as the demand dips the price or supply must do so as well. Oil companies don't want to settle for less money so they're not going to lower production until they need to.

The result is that in general people start to driver farther than they were, and the savings in efficiency disappears.

In a scenario like this the government would step in and introduce a tax on the fuel being sold, to keep the price from dipping.

In terms of the real world, you'd have OPEC reducing the supply to keep the fuel price from dropping and the incentive for people to be more efficient. Realistically, OPEC knows perfectly well that the oil will eventually dry up completely, and it's really in their interest to keep the rest of the world hooked as long as possible.

I think the problem is that the people who do grow food might stand to make more money growing switchgrass so then the land for food will be used anyways. I know if I was a farmer and had a chance to make more money growing a weed I would be all over it.

Well, why do you think farmers aren't doing that already? Why don't they all just switch to growing the single most valuable crop their land will manage?

One reason is diversity. There's some risk in putting all your eggs in one basket. If the weather is wrong, or if your crops get hit by disease, planting two crops instead of one means you'll probably have something left instead of nothing.

Another is the market. If a significant number of farmers stopped growing food crops in favor of switchgrass, the price of switchgrass would go down and the price of food crops would go up, and then it'd be profitable to switch back (or start new farms). So even if some farmers do switch, it'll balance out.

Re:Food prices

[sumdumass]

If you was a farmer, would you be growing dent corn or regular corn? If you answered dent corn or I don't know, then you most likely wouldn't be growing food. The vast majority of corn grown is dent corn which isn't use for food except maybe starches and animal feed.

On another note, Farmers usually plant 20,000-60,000 (Even as high as 80,000) corn plants per acre. Typically, 35 - 40k is common, at least in my area. With a 40,000 plant population, you are going to get around 200-210 bushels of corn which translates into about 28 tons or 25 metric tons (tonne) per acre (65% moisture). Now, according to this site [sciam.com], you can get about 5.2 metric tons of switch grass per hectare (around 7 acres). So that is around 175 tonnes for corn compared to around 5 tonnes for switch grass. You don't need to plow and seed switch grass, I assume it is the typical 2-3 cuttings a year like with hay though so some bailing and repeated cutting passes would probable make up for the plowing and seeding and it would probably be equal in fuel usage because fuel rate is calculated by PTO work.

Now the interesting part, you get around 28% product above what it costs to make the ethanol (the article says 25%) with corn. With the switch grass, you would get around 540% (per the article). Now the article is considering using the pulp as fuel for the refining process with switch grass but I assume that using silage from the corn crop could produce similar results if it wasn't ground up and left in the field. But you would likely gain around 49 tonnes of potential energy using the corn compared to 28 tonnes of potential energy going with switch grass in it's place. Now assuming the end product is going to be worth the same amount and the costs would be adjusted to reflect this in the pricing which means it would be better off to plant the switch grass on marginal lands in flood planes or other non-tillable and poor producing lands. Specking Soybeans in it every so often could possible take care of the nitrogen problems but a lot of the low lying marginal lands are already run off filters for existing crops which means they get carryover from fertilizers already in use.

I really don't think it would be beneficial to plant that instead of an existing crop unless the land is already so poor that it doesn't yield right on existing crops like corn. I don't see too much difference between silage and switch grass so an added benefit of planting corn might be a small amount of usable cellulose material that could be sold in addition to existing crop prices. You wouldn't want to do it every year but every other or maybe even every 3 years in between the last rotation might be a considerable source of product. It would take some work to store it but you might get about the same amount of material as if you harvested switch grass. There should be about 1 ton of silage ( metric tonne) for every 5 or 6 or so bushels of corn which translates to around 40 tons (about 36 tonnes) per acre (280 tons and 256 tonnes per hectare) which surprisingly is more then a crop of switch grass and is currently a by product tossed on the ground (it serves more of a purpose then waste though).

Re:Food prices

[Anonymous Coward]

Where are all of these nutrients and minerals going to come from to grow new plants?

I don't know if switchgrass is a legume or not. Legumes make their own nitrogen fertilizer; and cellulosic ethanol could be made from some kind of leguminous grass. You wouldn't need much of the other nutrients (phosphorous, potassium, etc.)

fertilizer is a safe, renewable source that is completely independent of petroleum...

No more dependent on oil than other products. Ammonia for nitrogen fertilizer is made from natural gas; not oil. That stupid oil company TV ad that lumps the two together ("Two-thirds of the oil and natural gas consumed in the U.S. is produced in North America") is very misleading.

The best alternative is to develope communities in a fashion that is conducive to both mass-transit as well as manual-transit (such as walking, biking, &c.)

Where does the ethanol come from?

According to TFA, while they can make it from almost any plant, they're starting with sorghum:

"...sorghum, which isn't a typical U.S. crop, can produce six times the ethanol per acre of corn, turning on its head the argument that ethanol production consumes more energy than it produces. China, the third largest producer of ethanol after Brazil and the U.S., is switching entirely to sorghum for its ethanol production."

Sorghum cane: 500 gallons
Corn: 214 gallons
Grain sorghum: 125 gallons

...turning on its head the argument that ethanol production consumes more energy than it produces.

Only David Pimental believes that, and he's in the pay of the oil companies.

Corn is a pretty bad crop selection for making ethanol. The water, fertilizer, direct and indirect energy requirements for growing corn are quite high.

For ever gallon of corn ethanol you make you need to burn away most of that gallon to make the next gallon of corn ethanol.

Even if they use ethanol from algae, hemp, switchgrass, or sugar cane, this might reduce our need for oil, but it can't replace oil used for other things like plastic.

For one thing, most diesel engines can't run on biodiesel unmodified.

That is wrong. In a new diesel, it will run pure biodiesel with no modifications. In a used diesel, the biodiesel will clean out the fuel system, so the fuel filter will get plugged. That is the only change needed.

And, you can't use "fresh" vegetable oil, either. It has to sit in barrels and ferment in the sun.

Ferment into what? It is running in a diesel engine, not a ethanol engine.

For vegetable oils, it needs to be warmed up before running in the diesel engine, but that is also the only thing needed to do when the vegetable oil is heated up before being sent to the engine.

Re:

Why this is seriously Stupid

[drinkypoo]

Everything we make Ethanol from is based on soil.

All mass agriculture is based on petrochemical fertilizers. The tomatoes that you buy at the local supermarket are fertilized with oil! Oh sure, not directly...

Here's the biggest lie, though: "It also happens to be about $2 a gallon cheaper than gasoline." In reality, the true cost of both this fuel and gasoline are much much higher than what you see (or would see, in this case of this fuel) at the pump.

See, the cost of gasoline is human lives. Whatever you think about the reasons for our current military activities, we have definitely gone to war for oil. Not to steal oil, of course, but simply to increase its value. See, when oil goes up anywhere in the world, it goes up everywhere in the world, because it's a global commodity.

Interestingly, so is corn, which is where we get most of our Ethanol. While in theory we can produce cellulosic ethanol from things we would normally burn, releasing the CO2 into the atmosphere for no reason and without benefit, it really hasn't turned out to be that profitable and so it has gone largely unexplored. Of course, that corn is fertilized with oil, so when it comes right down to it, Ethanol as we use it in America today is a fossil fuel.

Really, this is the ultimate rub with all topsoil-based fuels: while through careful management it is possible to fertilize fields simply through rotation and the use of your own shit, we actually waste our humanure instead of growing plants with it. Consequently the plants must be fertilized with non-human byproducts (e.g. blood meal, bone meal, animal shit, et cetera) in the case of organic farming, or with petroleum-based products (typically, anyway) in the case of mass factory farming (the so-called "Green Revolution".) Taking this thought a step further, as we're currently not feeding the soil that our food comes from, how do we plan to feed the soil that we're going to feed our cars from? I don't know if you've noticed, but they have rapacious appetites. It might be because they weigh an order of magnitude more than a human, and have an engine under 25% efficient, but what do I know? I'm not a physicist. I could be wrong.

I found your comment unrefreshingly naive when you said "Or is it just some evil price fixing conspiracy to make their 5% profits worth more?" The oil companies are making record profits right now, vastly more than 5%. On top of that, yes, yes it is just an evil conspiracy. Keep in mind that any time two or more people get together to screw at least one other person, it's a conspiracy. Conspiracies to fuck you out of money really are everywhere. This should not be a revelation by now, either.

Anyway, one more time: The only liquid fuel technology which does not have some horrible defect that makes it at least as bad as what we're already doing is algae-based biodiesel. It still has nasty emissions compared to anything you actually want to breathe (so does vegetable oil, honestly - though it's different) but it is actually potentially better than carbon neutral.

See, essentially all the carbon plants are made of (and it is their primary building block of course) is harvested from the air. Once you separate the lipids from the rest of the algae, the remainder is useful as fertilizer, high in nitrogen. You know, so you don't need ANFO, which makes a better bomb than a soil food. Oh, it's an OK plant food, but it's no good for the soil. Without healthy soil (soil is not just some mineral dust, it is a community of living organisms AND mineral dust AND the organic but decomposing remnants of organisms past, and should be at least 60% organic material) you cannot grow a proper plant.

The Amazon is on the verge of collapse, Brazil is about to become an incredibly shitty place to live (aside from the Favelas, which are already incredibly shitty.) Topsoil-based fuels

Electricity != Combustion Fuels

Th reason why we use combustion fuels is because the energy density is amazing. OK, so we use gasoline very inefficiently, and could double our efficiency without altering the shape and size of vehicles, but it is still a very efficient power to weight ratio.

Batteries are inefficient and costly as well as an environmental disaster to produce and recycle.

Maybe if we can make giant low leak capacitors, that would be better, but battery or capacitor, gasoline is still more stable than shorted high current wires in a car crash.

Even with a hybrid, you still got gasoline.

The answer, I think, has to be a clean burning fuel, maybe some form of alcohol. Seriously, in new england at least, we loose every leaf on most of our trees every year. If we were to rake that all up, press the oil out of it and ferment the available sugars, that may be some real energy for combustion.

Re:

[corsec67]

You realize that SwiftFuel is an attempt to replace 100LL avgas?

That is 100 Octane, Low Lead.

Avgas already has tetraethyl lead in it, right now. And it is definitely a hazard, as you point out.

Re:SwiftFuel sounds like a bad idea.

[plover]

The idea is to use SwiftFuel as a no-lead replacement.

Lead is currently added to avgas to retard premature detonation in the cylinders, and to increase the octane rating. One of the problems with unleaded fuels is that they produce higher compression than avgas. Today's unleaded gas would increase compression to the point where it would literally blow the seals out of the engines. They also have different chemical effects on materials that may cause deterioration in such parts as fuel lines and gaskets. Another difference is that the lead additives help protect the engine valve seats from eroding.

Airplane engines were designed to run on a very specific fuel, that had very specific properties. Avgas produces a precise amount of compression when it's burnt. The old engines were designed to be run at 100% of their potential power, so there is no tolerance for out-of-spec components, such as unleaded fuel.

In order for SwiftFuel to be an acceptable replacement, it will have to have very similar characteristics to today's avgas. Either that or it will have to be "close enough" so that older engines can at least be modified to burn it, and that would promise to be an unpopular, expensive decision (airplane repairs are never cheap.)

Re:SwiftFuel sounds like a bad idea.

[mrchaotica]

One of the problems with unleaded fuels is that they produce higher compression than avgas.

Forgive my ignorance, but I was under the impression that compression was caused by the reduction in volume within the cylinders between the bottom and top ends of the piston stroke, and had nothing to do with the particular gas that was being compressed. Am I wrong, or did you mean to say that unleaded gas detonates at lower compression ratios than leaded gas does?

Re:SwiftFuel sounds like a bad idea.

[drinkypoo]

You are not wrong. Compression is a feature of the volume, the bore, and the stroke. The volume is based on the bore, stroke, piston head features, and the head volume. Pretty much end of story. As per the Gasoline FAQ (google it) Octane Enhancers [...] are usually formulated blends of alkyl lead or MMT compounds in a solvent such as toluene, and added at the 100-1000 ppm levels. They have been replaced by hydrocarbons with higher octanes such as aromatics and olefins. These hydrocarbons are now being replaced by a mixture of saturated hydrocarbons and and oxygenates. Incidentally, they were specifically replaced by MTBE, and have since mostly been replaced with Ethanol.

Unleaded fuels without other octane boosters are prone to predetonation. That might be what the guy was talking about - that "pinging" noise of a so-called knock condition is the sound of the piston vibrating in the cylinder as it tries to compress an expanding mixture. Hard to say.

As for eroding lines and such, this is true, especially of Ethanol. A lot of that aeronautic stuff is pretty damned antiquated. I wouldn't be surprised to find that replacement parts are still sold with leather seals and whatnot. It wasn't an airplane, but my 1960 Dodge Dart (2dr, "Phoenix", 318ci big block hemi) had a 650 CFM Carter carburetor which had a leather acceleration pump flap. When the switch from leaded occurred, a lot of these cars sort of fell apart. Not mine though. Must have gotten lucky. Also I used the expensive lead substitute, maybe it was good.

Re:Australian Government Fuel Excise

[larry bagina]

Per the article (Cringely, so not exactly trustworthy, but I don't feel like verifying the numbers) wholesale ethanol costs $1.42 a gallon and SwitftFuel production costs are ~40 cents/gallon. 1 Barrel of oil (42 gallons) currently goes for $130. That's converted to 20 gallons of gasoline (plus 20 gallons of other useful stuff), so the raw cost of gasoline is ~3.09/gallon. That's reasonably consistent with these [ca.gov] numbers from the California gov't. Refinery costs for gasoline are slightly less, but not too far out of line.

Therefore, IF the ethanol price and ethanol conversion costs are accurate, the end user cost could easily be $1.50-1.60/gallon less than gasoline.

You're right - we'll never see a battery powered Hummer. But electric vehicles that serve the needs of 90% of the population have been in mass production (even if subsequently shut down) since 1996. All because the government of California demanded that car companies deliver them.

Now consumer demand and energy awareness are at an all time high. They're backordering SmartCars and Apteras and even high-performance Tesla Motors sports cars into two and three year waits.

He talks EXACTLY WHY the solar power->electric->battery WON'T WORK! Because it will take over a decade for electric cars make it to most households even if we outlawed all non-electric car sales today! Cars have a life expectancy of 10 years or more, which means you will see that same 2007 car that was bought last year on the road until 2017 or later. The government could even outright outlaw all gas powered cars today and still you would not see a full uptake of electric or hybrid cars for several years because people can't afford to make the purchase. Again, it is usually every 3-4 years for someone to get a different car, but not necessarily a brand new car (usually a used one), and most cars will see at least 10 years and 3 owners. This means people expect to have 10 years to save up to purchase a brand new vehicle, or 3 years to save up for a several year old used one. Any change that would be significant would need to be able to affect ALL cars at the same time, not after 10 years. This is why a fuel change that can be used in existing cars is the method of choice to change our energy usage.

Ultimately, prop planes and cars use the same technology, with some differences in details. One of those details is that airplanes don't have the same emissions requirements, allowing them to use leaded gas with a higher octane rating. The consequence is that they can run a higher compression ratio, and thus be more efficient.

If SwiftFuel can provide an additive that produces octane ratings on par with leaded gas, we can all jump for joy. Combined with direct injection, we could potentially see gas engines with compression ratios and supercharging boost on par with diesels.
