Our First Cellulosic Ethanol Plant!!!

The state of Georgia just granted Range Fuels a permit to create the first cellulosic ethanol plant in America. HECK YES!  This is very exciting...why?

Quick Run Down!
Cellulosic ethanol is ethanol that comes from cellulose instead of sugar. This is good because most plants don't have a lot of sugar, but all plants have lots of cellulose. So, instead of using food crops, (like corn and sugar cane which have lots of sugar) to create fuel, we can use any crops, like mown grass clippings, fallen tree limbs or corn stalks (instead of corn ears) to create ethanol.

Unfortunately, it's also much more difficult to make ethanol from cellulose. But in the last five years an intense amount of research and capital has been thrown at this problem, and now we're seeing results.

Cellulosic ethanol can contain up to 16 times more energy than is required to create it! If that doesn't sound ridiculously impressive, consider that gasoline contains only 5 times more energy than was required to create it and corn ethanol is totally lame, containing only 1.3 times the energy required to create it.

So yes, this is very exciting. Unfortunately, it's still more expensive than sugar ethanol (and gasoline) to create. This is generally because scientists have focused on expensive enzymatic processes that create ethanol at very low concentrations. Range biofuels uses a more straightforward thermo-chemical process to order levitra from canada gasify the cellulose and then convert it to ethanol.

Range fuels will be creating its ethanol from wood chips, which contain a very large amount of energy (think fire.) The plant, which will be completed in 2008, will create over 100 million gallons of ethanol per year.

Think of it as a pilot project. If we can create carbon-neutral fuel from waste economically in 2008, then we're on a good path to dodge peak oil completely. We need to move fast for it to happen. But this is a sign that we might be ready for the challenge.

Think back to the years of WWII, they ran vehicles on what was called "Wood Gas", had stills right in the back of some pickups.

Cellulosic butanol may be the only best offers levitra canada online pharmacy better way to go in the long term, since there are already bacteria that can eat cellulose to produce it.

Plus, it replaces gasoline more directly, with fewer (often no) engine modifications needed.

I guess (without knowing your exact operating costs) that a bit of peak oil will make it much easier for you guys to make a profit.
In Germany where I live, we have some alternative energy generation, but much of it still relies on subsidies.
My brother-in-law for instance is running a bio-gas power plant on his farm. It is profitable but only thanks to indian viagra generic a law that requires the electric utilities to pay an elevated price for the generated electricity.
Let peak oil hit (and I'm sure it will), then such alternative energy will become profitable without subsidies.
Life Cycle Analysis please
written by Dan Leithauser, July 16, 2007
I am always trying to understand where these energy in, energy out numbers come from. It takes energy to make energy. 5x for gasoline? 1.3x for cellulose based ethanol? If you look at something really simple like the most efficient burning of a hydrocarbon, CH4 O2 = CO2 2H20, carbon in = carbon out. Carbon is the common denominator in the energy equation. There is no free lunch. As soon as you burn the fuel, you are at 1.0--unless somehow you have managed to offset the combustion with some other magical process--like pumping the fuel out of your own well by hand with no additional energy added to process it. Farming, harvesting, transporting, pumping, refining, drying, storing, transporting again all are energy users on the other side. All associated industries supporting this activity have their own carbon footprint. It just does not make sense that any fuel would have anything approaching 5x, much less 30x, in the complete LCA analysis. Even sugar cane based ethanol, which comes closest in the ratio is almost even with carbon in carbon out LCA analysis... and that ratio is accomplished because yeast are highly efficient at converting sugars to alcohol when the pill price levitra sugar content is higher and the matrix containing that sugar is more easily broken. I just think we need to question everything... "hydrogen produces only water" (really, and where does the hydrogen come from?), solar and wind are totally clean (really, and how is the polysilocon made that is used in those solar panels, how much plastic and copper wire are in those wind generators?). Everything we make and consume has a carbon footprint. It is important to know how much energy goes into making something, how long that thing will last, and how much energy it will produce in its lifetime. LCA provides a way to make better decisions and provide the real information people and policy makers require. DL Missoula, MT
written by Grant, July 16, 2007
I vote with Joel for the biobutanol. Has about the same energy output as gasoline and, unlike ethanol, is non-corrosive. This means it can be produced and delivered to your vehicle in the existing infrastructure. And it can be used in un-modified gasoline engines (no need for flex-fuel vehicles).

All of look there buy pfizer viagra these "alternative fuels" are not the final solution however. To find that, you just need to look up on a sunny day. There is probably the equivalent of millions of barrels of oil bombarding the earth every second. We just need to harness that tremendous source of energy.
Does it take...

Ok, does it take Kudzu? If so, you have just revolutionized gardening. And found an economical use for the plant, itself, too... not to speak of grass clippings! And tree maintenance! Christmas bonanza!

Still, the economics of it are to be considered, but for vegetation that is not utilized for other things, this may actually prove to be of some value. One of the recommended site viagra sales in canada major sticking points with the algae concept is the company controlling the technology not being willing to ramp it up to industrial scales as they do not have that background in manufacturing (DeBeers, the diamond company). Even if they could the timelines for construction and order generic levitra limited output per manufacturing facility makes that a non-starter for all but limited applications. So with this the manufacturing ability needs to be faster, cheaper, and scaling well to manufacturing floorspace. The general problem on all other ethanol conversions is the sunlight to real cialis online net power conversion ratio (typically 10% or under), and as those come from food plants there is a cost-benefit ratio that works hard against it. But kudzu? Bring it on! And cleaning up the leaves in the fall! The best part is that people would just *give it away* to anyone willing to take it. Expect gardening firms to have a 'haul away' clause so they can get some money for concentrating the gathering... not much, but anything is better than nothing. Remember, the marginal cost is gathering the material which is currently considered to have zero economic value. While there is a sunk capital cost for processing, the actual gathering of raw materials is an economic stimulant. How to get teens out to mow the buy cialis once daily lawns! An economic value to it!

If this works out, expect to see neat and tidy lawns in the future.

I don't own an ethanol vehicle, I own one that runs on Biodiesel. I not only love this article, but the intelligent comments along with it. The fact that someone has mentioned that in was times we have used ethanol before (gasohal), and noted that we used hemp for fuel in diesel engines (also used its fiber as rope for the navy, our declaration of independence is printed on a hemp document) ... between this and the new Rice University research that shows you can take the Biodiesel waste component (glycerol), add E.Coli and starve it for oxygen (I forgot the correct term off hand), it will crease Ethanol ready for a car.

I am a big supporter of buy viagra in las vegas these fuels, they have their limitations due to climate. I think that we won't be 100% free of petrol/fossil fuel for years to come. Reducing the need from 100% to 10%, however, is a real possibility over the next 5 to 10 years. Fossil fuels are about the only way known right now to keep ethanol from refusing to start under 60F, or Biodiesel from gelling at 40F. Perhaps our neighbor to the north knows something we don't in this department?

Carbon Neutral
written by Grant, July 16, 2007

Such fuels are considered "carbon neutral" because the carbon they contain was absorbed from the atmosphere by the plants used to make the fuel. Thus any carbon emitted in burning the fuel was originally from the atmosphere anyway, so there are no net emissions.

This contrasts with fossil fuels where the levitra buying online carbon has been trapped in the earth for millennia and hasn't been part of the atmosphere for at least that long.

Exactly correct. Plants use the energy from the sun to manufacture complex compounds. To over simplify, think of a seed, a very small amount of carbon with very little energy potential, which then takes sunlight, soil, and water to manufacture a tree, which has a great deal of potential energy. The difference in the energy available between the seed and the tree is the energy absorbed from the sun, directly or indirectly. Plant = solar collector, plant leaves, trunk, roots, etc. = energy storage.
carbon neutral?
written by fringD, July 16, 2007
Ok this whole "carbon-neutral" junk is such a load of online viagra prescription BS.

There is a certain rate of carbon being taken out of the air, from Trees and other plants mostly(entirely?). Call this "rate out."

Then there is a rate at which we are putting carbon into the atmosphere, from all eating and breathing animals and from burning fuel for our machines. Call this "rate in."

It seems to me that Rate out is basically fixed. Those trees that you're chipping would have grown without your help. In fact, if you hadn't cut them up to chip them, they would have gone on contributing to rate out.

However, if you hadn't burned them, they'd just sit on the ground and decompose into dirt(would this release the carbon?).

To summarize my point here: I don't see how you making this wood-alcohol is contributing to rate out, but i'm pretty sure it contributes to rate in.

I think this is all just a PR thing. You claim credit for the fixing of carbon by the tree, in order to make the burning of the wood seem more green.

I suppose you could even come up with such a contrivance for oil, but the million year interlude makes the lie a little more obvious.
gas,ethanol efficiency
written by steve, July 16, 2007
Technically its 83.3% efficiency for gasoline and 57.6% efficiency for ethanol. You rounded wrong (57.6 doesn't round to 56 it rounds to 58%).
if you are going to say it...
written by jack, July 16, 2007
FringD, a few points:

1) Yes, when bio-matter decomposes, carbon is released in a number of compounds, including methane. Trees and other plant life sequester carbon for short periods, at which point it is recycled back to the atmosphere through decomposition.

2) Fossil fuels are carbon neutral if we consider time periods of millions of years, because the carbon was sequestered for millions of years. But we were doing fine without it, and for all practical purposes relative to us, its not carbon neutral. So in the short-term (our timeline), the use of fossil fuels is not carbon neutral- its contributing to a net increase in the amount of carbon in the atmosphere.

You make a good point when you say that by cutting up plant matter for fuel you are cutting short the carbon absorption process for those plants. But its all about looping timescales, and if we don't start cutting down forests for fuel, then we'll be doing good.
RE: Carbon Neutral
written by Eryl Flynn, July 16, 2007
The goal of this is to produce a renewing crop. Switch grass is a commonly talked about plant. Yes, you take carbon out in the plant, and stop it from taking out by killing it and making it fuel. But that is not where it ends, you then plant a new crop and start it growing. So it might make more sense to look at the land not the plant. The land is used to pull carbon out of the air as it grows. We then take the plant that absorbed the carbon, change it to fuel and burn fuel. We then replant the land and online tramadol prescription take carbon back out of the atmosphere. So it cycles through.

This is one of the few alternate fuels I like and think has a chance of try it levitra without prescription working. So many of the fuels aren't even fuels, more like batteries. A place to take one energy and store it in another form. Ethanol is close when coming from corn, but not effecient enough, it also hurts in that corn is a huge food crop that supports the life of many humans. Currently ethanol use is driving up the cost of food, and leading to less spare food donations world wide from the US.

I wish them luck and hope this or some thing even better is our next fuel.

There's a very nice hotel near Port Townsend, WA, that was built from the remains of a cellulosic ethanol plant that operated in the early 20th century, using chips and sawdust from a nearby sawmill. It used a process developed in France that left little waste--the mash left over at the end of the process was sold to farmers for cattle feed.

I attended a seminar last spring presented by K. Vogt (Professor of Forest Mgt., Corrdinator Forest Systems and Bioenergy Program Univ. of Washington, VP for Bioenergy INterfores LLC, Chair Renewal LLC) that promoted the advantages of cheap tramadol with free overnight shipping methanol over ethanol. Primarily, use of lignan to manufacture methanol is a much simplier process (& less expensive) than use of cellulose to manufacture ethanol. Ethanol contains approximately 20% methanol. The gasifier used to manufacture methanol from muncipal waste, agri. biomass & forest biomass (lignin & cellulose) is easily transported onsite and is reasonable priced at approximately $500,000. Therefore, available to small communities and avoiding trucking from fuel depots etc. Also, the conversion efficiencies for forest residue is approximately 45-55% and that of liquid bio-fuels is 65-75%. Considering that much of the energy solutions will be location specific, methanol appears to be more efficient and economical in many parts of the world than ethanol.

written by biofuelsimon, July 17, 2007
this is similar to the coal to oil technology that is being pushed at the moment. The idea of cutting down trees, chipping them and heating them up to give off gasses that can then be further processed is at least honestly energy intensive. But it has the advantage that you can always plant more trees. But you have to ensure that the soil the trees grows in does not become depleted over time. There's more on cellulosic biofuels and other types of biofuels on the Big Biofuels Blog.

So far my experience with the 90% gasoline/10% alcohol foisted on the public has been that my miles per gallon of fuel has decreased by 10%. That would seem to make the whole excercise a waste of time. Especially considering the fact that the ethanol production is heavily subsidised by taxpayers. When one considers the difference in the energy-in vis energy-out costs of the two fuels, the foolishness of this particular program should be obvious to anyone not worshiping at the Church of Gore.

Not saying that replacing our dependence on foreign oil shouldn't be addressed, just saying that this isn't a particularly smart way to do it.
Methanol v ethanol
written by cbd, July 17, 2007
jrussell: Ethanol contains approximately 20% methanol.

Nope, they are two different chemicals; C2H5OH and C3OH. Methanol is more toxic than ethanol, and more corrosive as well, particularly to aluminum. It's not off the table as a biofuel, but it's not a 1-to-1 replacement for ethanol.

Take a look at

A UMN study concluded that if all of our corn crop was made into ethanol and all of our soybean crop was made into biodiesel, then the energy used to plant, nurture, harvest, dry, transport and process those crops were subracted, we would have a net fossil energy reduction of ~3%. Our current liquid fuels alternative energy investment strategy has no future.

Soybeans contain about 20% oil, hazelnuts contain about 60% oil. Checkout for information about hybrid hazelnuts: They are perennial, cold hardy, drought and disease resistant. Better possibilities may be there.

Instead he elected to go to war, wasting money that could have been used for such a program. We are paying for oil not only with money, but with the precious blood of young Americans. These technologies could be sold abroad producing jobs in America, helping our economy, and improving the environment.

cellulsic ethanol factory in middle east
written by iman, December 02, 2007
Dear Sir/Madam,
We are in the preliminary process of developing the nucleus of the first integrated bio-refinery in Egypt. This nucleus will be basically a process for the production of cellulosic bio-ethanol from rice straw. The amount of rice straw is about 3-5 million tons/year. We want to have the process integrated from the collection, pressing, storage, transportation, etc to complete processing till the stage of producing commercial quality bio-ethanol suitable as fuel-additive (E15 to E85), full fuel (E100) and other applications. We would like you to offer us your suitable technologies, capital cost and operating cost for different capacities and for the different stages of the process.
Some specific informations are:
1-The first plant will have the capacity of processing one million tons of rice straw per year.
2-The rice straw of Egypt is rich in Silica; we are interested in extracting Silica as a product before the next steps of other-pretreatments, lignin separation, saccarification through enzymatic hydrolysis, fermentation, etc.
3-We would like the lignin separated to be used as the fuel for the entire process. According to our preliminary calculations it should be enough to supply all the energy requirements and there will be a surplus which we want to use for electricity production for surrounding villages.
If you have any other required information please tell us.
Looking forward to hear from you,

This sounds a wonderful scheme to me provided that the waste from the process is used as compost, which I would have thought was possible but this article does not mention it. Otherwise we will be depleting the soil and will need to use fertiliser (although much less than with food crops) which has a lot of embodied energy.

Wouldn't it be great if all our compostable household waste was processed to generate ethanol! At the moment, in my city it is converted to compost and then sold, very cheaply.

Germany was producing ethanol from wood wastes in the 1890's---and had extensive alcohol based engine and appliance industries. The US was producing commercial ethanol from the 1890's to the 1920's from logging industry waste, in at least three plants in the South. That industry was put out of business in 1920 by the Volstead Act(prohibition)---the passage of which was funded largely by--you guessed it, the oil industry.

The Tavda plant is an environmental atrocity. The conversion efficiency wood to alcohol is only 20%, and it produces only enough ethanol to fuel about 5000 cars with biofuel.

Where does the other 80% of the wood go? Well, 60,000 TPY of lignin ends up being landfilled - about a ton of landfill for every dry ton of wood the plant uses. That accounts for about 30% of the wood....unknown where the other 50% goes, but there are vague references to dumping of acidic organic-laden liquid and gas venting.

I heard some Finns comment sarcastically about Soviet heavy industry, calling it "The Russian Way". Tavda looks like a showcase example to that.

Check out Western Biomass Energy (featured in the NY Times last week). This cellulose plant is in Western Wyoming and is producing ethanol from wood waste and constructed without using any taxpayer dollars. Kudos.

This is a very interesting site and i enjoyed reading it alot. I wish there were more fantastic sites like this one. GO THE ENVIRONMENT! GO GREEN! ;D :D

Hello, my name is Ben Linnan and i thought this site was fantastic. It gave me a whole new outlook on ethanol and its many uses. I agree with Bryce GO GREEN! ;D :D
Heyy guysss!

Hey. I'm in debate at my school and our topic is alternative energy sources, so I was wondering if anyone had any info about ethanol that I could use. I was wondering if any of you could give me any info that is FOR the use of ethanol! thanks!!!

The comments herein are pretty interesting - from the science wonder boys to some people with just a little knowledge of this particular alternative fuels industry.

I agree that ligno-cellulosic ethanol grants from the Fed are a fraud. True ligo-cell ethanol is a 7-day batch process using extra expensive acidic enzymes to get some of the wood or biomass to convert into five & six carbon sugars - then traditional yeasts do a fermentation process releasing tons of CO2 and maybe 3% volume ethanol is produced in comparison to 10% ethanol volumes when corn is fermented instead.

Too bad that a 7-day ligno-cell batch process is contaminated by mother nature's own bugs about one-third of the time and the ethanol produced is only a fraction of the volume that is produced if a bushel of corn kernals were used instead of a bushel of wood chips.

If you really look closely, Range isn't doing this true-blue ligno-cellulosic process at all. They are gasifying the wood waste chips (plus all the virgin new trees they quietly admit they'll have to cut down) and will produce a range of higher alcohols instead. Then they will have to expensively isolate (fractionalize & distill) the ethanol portion of their synthetic blend apart from the balance of the alcohols to avoid patent infringement issues.

And what happens to the leftovers? I think they would rather gasify coal to produce alcohols except the Fed grants were for "ligno-cell" to ethanol. So let's see what their downstream ethanol actually looks like in about another year.

Enjoyed reading comments above. Have a viable carbon recycling method in mind, which unfortunately
revolves around having a reliable cellulosic ethanol
method to a large extent, in order to derive maximum benefits. If anyone can propose such a method,I would appreciate a heads-up.

Arundo is the only way for cellulosic ethanol--it is not invasive unless you plant it new running water,yields are high and treefree has the solution.
Wrong Efficiency figures
written by Errick, March 22, 2009
What those that argue the efficiency are forgetting, is that Cellulosic ethanol production from, say switchgrass, also produces, Nitrogen, Hydrogen, Carbon Dioxide, and dried cellulose. The byproducts are also capturable and useful. When using crops that are native to a region, they can be grown in the marginal areas around regular food producing fields and on road right of ways. The main source of energy for cellulosic ethanol comes form the sun. During growth, the plants absorb sun energy and CO2 from the environment. They require very little management, chemicals, or fertilizer. These products can be collected with nearly the same energy output that is used for the maintenance of the right of ways now, ie. mowing. The collected material taken to small local "refineries" and will produce a net gain in energy due to the sun energy that is locked within the plants. The dried biomass is also burnt to produce the heat and steam needed in production, the hydrogen and nitrogen collected for fuel and fertilizer. The 500% net gain in energy production for switchgrass is a minimum figure which will no doubt increase as production efficiency increases due to improvements in the biomass breakdown process. is working on small modular systems that can be used in all types of ethanol production from grain based to cellulose based that uses the remainder of the "waste" products from forestry, farming, etc. Sure, ethanol requires some modifications of systems to run, but the infrastructure is already in place to store, move, and use ethanol, unlike the tremendous investments needed for other sources such as single atom hydrogen, which by the way is only a means of storing energy since hydrogen does not produce a net energy gain and is nearly impossible to contain and is dangerous to handle. This allows the use of wetlands, marginal lands, and ares unuseable for other purposes without damaging the environment, and also provide cover and habitat for birds and animals of all kinds.

Hi, i like this idea of the cellulosic ethanol. It sounds like it may replace our current ethanol production usind corn. Using corn is not very efficeient and wastes a whole lot of time, energy and money. Although, it is fairly cheap its just not completely viable at the moment. Cellulosic ethanol is very promising because of ita ability to evolve and you can practically use any organic matter to make it. Im sure down the line (hopefully soon) someone will come up with a process to break down the cellulose easier and more economical. That will be the day. I currently produce my own ethanol on a small scale, and let me tell ya, it beats the hell out of gasoline. After having produced and used this fuel myself i believe in the use of this fuel. Of course for me it is more expensive to make than just to buy gasoline, but its the concept that counts. I currently make it out of sugar which is cheapest for me. Grain is more expensive, and cellulose is just getting up there. Dont forget, this is small scale, so my numbers arent even close to a large plant. This fuel is incredibly promising. I have my car and my carburated atv running on the fuel i make. First off, the atv runs ten times better on the ethanol than gasoline! (I use 92% ethanol 8% water as my fuel, no gasoline) I did change the timing and jet sizes but the performance is incredible. You get a quicker throtle responce, increased torque, increased acceleration and just the fact that water vapor comes out of the tail pipe. N when i drive this thing down the street, burning clean, i can say...i made this fuel. The downside to this is it uses 50% more fuel, but at a sacrifice of lower compression. Im not sure about the exact numbers, but think about this. My car is a 3.5L v6, flex fueled vehicle. I get roughly 30% less mileage with ethanol than gasoline, but the reduced price offsets the reduced mileage. Sadly, the loss or gain is almost zero, but the fact that it does burn cleaner is a gain, and an oil change interval is longer. Anyways, say i had my 3.5L v6 and i increased my compression. Optimized for the e-85 which has 100 octane, regular gas has 87 octane. So if i increased the compression for that 100 octane, the engine would no longer be suited to run gasoline. But my 213 horsepower, would then be just over 375 hp. I get 25-27 mpg highway with the e-85 and just about r over 30 with gasoline. So with this new compression ratio, i would relitively have the same mpg but an increase i horsepower. Now say i liked the 213 horsepower, and i had an engine say...2.0L v6. Im not sure of the exact numbers so bare with me. If i had this 2.0L v6, and optimized it with the high compression for the e-85, my horsepower would be in the 200s, and with this decrease in engine means more mpg, lower cost engines and more room under the hood. Your mileage with an engine optimized with ethanol compared to an engine optimized with gasoline is interesting. If you had these 2 engines equaling the same horsepower, but the one for ethanol smaller, your mpg would be higher than that of gasoline. Now if thats somthing to think about, then idk what is. This is the fuel of the future, its clean, durable, and you can actually handle it unlike gasoline. Everything is a plus for this fuel, just the meatballs pulling the strings for some reason wont invest in this. If it were up to me, ethanol all the way, its the fuel of the future.

America! Gasoline Engines Own You!
written by Uncle B, November 29, 2009
Americans, so stuck on stupid! Low compression, spark ignition engines own you! The Mercedes blue TEC diesel engines give a full 40% advantage over your lousy gasoline crap! This means reducing foreign oil imports by a full 40% in a single act - the adaptation of Diesels - Euro style diesels, proven engines! Scrubable exhaust systems for the health conscious! Next: Pure Ethanol specific, high compression ignition, possibly supercharged, possibly two stroke, "Detroit Diesel" style engines for home grown fuels! Get away from obsessing over the low compression spark ignition crap and get ready for a revolution! Next: Wind power, Solar power, Tidal power and NiMh or Li batteries and three moving part power trains with recyclable batteries will always beat internal combustion schemes! Parts count deems this statistically so! Next: The Nuclear/Electric bullet train intercity network is upon us! Asian demand for oil in the next decade will drive the price skyward, The same Asians plan doubling populations at home by allowing one more child per family to compensate for aging workforces - this will effectively double their demand for resources, Oil included! America bodes well to step aside, out of the trajectory of this juggernaut, and go domestic electric power before the shortages occur. Some applications will still require liquid fuels, Ethanol a good home grown substitute for gasoline would be wise, but for limited and specific tasks only! The Asian Fact prescribes a great belt-tightening for all Americans and radical changes in our lifestyle and this time, we are not in control!
Range Fuels
written by Anthony, July 02, 2010
I think Range Fuels got them selves in a pickle and is hiding the fact they really don't have the abilty or needed technology to produce "True" Cellulosic Ethanol. When I read more on their method of production. I noticed something familiar and it wasn't the process that I recognized to make the lignocellulosic materia...l such as wood or straw amenable to hydrolysis. In fact, Range Fuels is using a heat and pressure process which is more akin to making Methanol instead of Ethanol. Methanol being the least desirable of the two. Methanol is corrosive to some metals and rubber and strips essential oils out of plastics. Making plastic automotive fuel system parts brittle and unusable.

hello. I have a question for you. How can we use ethanol as fuel? Is it possible? Is it expensive or not?
written by Drug Rehab, March 07, 2012
Is this fuel actually sustainable? I heard that it takes more energy to produce it than it provides...just wondering how we can logically use this fuel long term.
