SwiftFuel Alternative To Alternative Fuels 725
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."

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.

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.

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.

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).

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).

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.

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.
And I have to say, I hope gas goes to it's true cost where it covers our involvement in the middle east. Anyone who wants to stick with their 6 liter engine after gas hits $12 a gallon is getting exactly what they deserve.

The whole point of SwiftFuel is that it uses an existing infrastructure, as opposed to converting transportation to electrical-based. But I'm with you on the corp patent-based con, although I suspect that first off the patents are at least co-owned by Purdue, and second that the .gov would expropriate them in a nanosecond if they felt this was a good enough idea.
Anyway; this fuel, or something like it, will be needed to tide us over until battery or hydrogen storage technologies have caught up. Or we g

Here's a hint: it's all dead organic material, which originally gathered energy from something that gathered energy from what original source? Yes, that's right kids! It's the sun! Revered for millenniums for a reason...

Passive solar plants are already in use all over the world, and even store energy using gravity or other passive methods that waste very little energy. Many small power plants can decentralize the grid, improve efficiency since the grid is smaller, and are much more viable than millions of little ICEs.
Imagine, Wal-Mart borrows ten billion dollars to install solar panels to cover their parking lots, which stop local heating effects, decrease A/C usage in all customer cars, and provide them with another revenue stream all in one master stroke.

We need to conserve energy dense fuels for situations where they are are truly needed (emergency vehicles, long-haul transportation through sparse landscapes, aviation).
What people are upset about is that life is much less convenient when we're all not driving powerful vehicles than can carry 10 folks and tow a boat on a whim. Well, tough shit. You may have to carpool or take the bus. You may not be able to keep your own jetski in a garage a hundred miles from your lake house. These are privileges, not rights.
Algae based biodiesel is interesting, but again, we need to get away from ICEs except where they are absolutely necessary. An electric car can receive power from any source - nuclear, coal, and even biodiesel through small on-board generators. ICEs will always be addicted to one type of depletable resource - that derived from dead organic material.

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.
