I would like to find out how much castor oil for Bio-diesel production can i get out of a crop yield from one hectare? The same with Soya beans.

Castor = ricin = terrorist!

No, because it can be produced without petroleum as it was for thousands of years before we invented the combustion engine. People will always try to survive, they wont just lay down and die because they cant but some diesel in the tractor.

haha good question :]\nwe're just studied those in math, and a lot of our problems had "real-life" situations, so i'll just give you some examples of them.\n"A farmer has at most 80 acres for which to plant two crops, corn and wheat. Planting and harvesting cots, for which no more than a total of $12,000 is available, are $300/acre for corn and $100/acre for wheat. How many acres of each crop would you suggest he plant?"\n"Ken is planning a picnic for the youth orchestra. He is going to make chicken sandwiches and egg salad sandwiches. He will make no more than 20 sandwiches, because many people may bring their own. He figures that the number of chicken sandwiches should be at least twice as many as the number of egg salad sandwiches. Ken says that there is only enough chicken for 16 chicken sandwiches. He says that there should be at least 2 egg sandwiches..."\nI think these could be times in which you could use a system of inequalities. I guess if you had time to calculate it all...\n<333

We give away soy to foreign governments in the form of aid despite the fact we could run our vehicles on it.  Smart, eh?\n\nI would switch as long as it was feasable.  Facilities that dispense alternative fuels are nowhere to be found near me and I don't have the technical skills to mix the stuff myself or else I would in a second.  I deleted the emails but I was in contact with a guy in CA last year that convinced the local government on one of the Hawiian Islands to convert their recycling truck fleet to soy power.  He had some good ideas.  He also takes a soy powered VW Wagon on tour around the country to advertise the benefits of biodiesel.  \n\nGood luck if you choose to convert.  I haven't yet but maybe a few semesters at the vocational institute would pay off in the end.

Yes you do, for a couple of reasons.\n\nFirst, a Diesel engine is more thermally efficient than a gasoline engine.  Therefore it can extract more power from the combustion process than a gasoline engine.\n\n\nSecond, diesel fuel contains more energy per gallon than gasoline.  A gallon of gasoline, when burned, will produce approximately 125,300 BTUs of heat energy.  A gallon of diesel (petroleum based) will produce 138,200 BTUs of heat energy.\n\nB100 is slightly less because B100 has less energy per gallon than petro diesel.  About 8% less energy per gallon, so figure roughly an 8% decrease in economy with B100 vs. petro diesel.

There are lots of online ag education resources that deal with this. See sources for links.

Does grasscutter = lawnmower?\n\nI didn't know lawnmowers had bile?!?!  Or are you talking about the engine oil????

Seems to me that a farmer has three potential options with a piece of land:\nHe can grow a food crop.\nGrow a non-food crop that he can sell for cash e.g. tobacco or cotton (I think that's probably the distinction that the question is trying to make)\nUse his land for some other non-agricultural use e.g leave it fallow, build a theme park.\n\nSo the question is asking what the impact of growing too many of these non-food cash crops might be.\n\nI won't do your whole project for you, but these are the areas I think you should be visiting.\n\nEconomic impact\nWhat will happen when a lot of perhaps one particular cash crop is grown.\nSupply and demand suggests prices will fall\nMaybe balance of payments will improve if you can export\nMaybe foreign investment will come in to exploit the local availability.\nMaybe other industries will grow up to exploit the cash crop (think textiles or cigarettes).\nWhat will happen to the price of food though? Increase?\nWill you need to import more?\nIs famine a possibility?\nIf you are relying principally on one or two cash crops to generate income to spend on food imports what happens if the crop fails?\nThere are positive and negative impacts.\n\nEnvironmentally\nSo what happens if large areas of forest are removed to provide new fields for cash crops?\nWhat about the impact of large tracts of land given over to one crop.  We may be talking dust bowl here.\nWhat if the crop requires intensive farming methods - high use of fertiliser and pesticide.\n\nPolitically and socially\nWhat are the impacts of being a net importer of food?  Particularly if this means the difference between the nation starving or not.\nWhat about the extra cash coming in?  It could be spent on education, infrastructure.\nWhat happens to the Government the next election after a famine?\n\n5. Traditionally governments have used various methods:\nSubsidy: Give the farmer extra cash for producing certain crops.  Look up EEC common agricultural policy.\nTaxation: Tax the farmer for producing the crops you don't want.\nTrade barriers: Put import tariffs on the crops they want grown in the country.  Prices rise and more farmers are encouraged to grow the crops.\nQuota: Not so much in the western world, but certainly the case in the old Eastern Bloc - simply dictate to the farmer what he can grow.\n\nHope this helps

corn based ethanol is going bye bye. cellulose based ethanol will replace it over the next 10 years. \n\nWhy? well cellulose convertions are said to be more efficeint than corn based. Corn produces 2.5 tons per acre per season. Cellulose producing crops like Industrial Hemp(legal in canada but not US) produce upwards of 10 tons an acre and is grown without subsidies required to hold down the price of corn. \n\nAlso cotton is more profitable than corn, so is industrial hemp produced for the textile industry. Industrial hemp is also more profitable going to all other uses besides ethanol.\n\nThe food and clothing is already more expensive than ethanol is, so that is an additional shield.

Biodiesel from Jatropha.\n\nUps: It's really cheap, No replacement or modification of your existing diesel engine.\nDowns: Yet to be Commercially Available.\n\nThere are other ethanol and oil based biodiesel variants available in some parts of the UK and the USA. But to use them, you've got to modify your existing diesel engine.

temperance in all things is the key. Yes, you can have too much flaxseed oil.\n\nIf you are worried about your omega 3,6, and 9 fatty acids, you can let your worry go with a few tips.\n\nEat a wide variety of vegetables, fruits, nuts, seeds, and legumes. Don't have great variety at one meal, but over a week or two.\n\nInclude almonds, walnuts, soy beans, ground flaxseed, each week (soy beans once or twice a week, the rest have 1/4 cup each up to every day (about six almonds, etc). That will adequately cover your omegas.\n\nremember, not long ago we didn't know omega 9 existed, nor vitamin B15, but people were doing alright on a balanced diet.\n\nI am a total vegan, have been for 15 years. If you choose to use oil, like flaxseed oil, just be temperate, and you don't need more than a teaspoonful a day, with all the other sources of omegas. olive oil is great for omega 9.

i wouldn't expect anyone in the oil business to do anything to change the industry (although bush HAS passed a law stating that government vehicles must be equipped to use ethanol as an alternate fuel). it is really up to americans to change what they use, because the oil industry is entrenched and will not check themselves -- business just doesn't work that way. republicans hate to have government make the people do anything, so the likelihood of us passing laws such as those in Brazil are slim to none. I am personally just going to buy a flex car and run it on ethanol. No more petroleum fuel for me. E85 is produced without the use of petro-products, is home-grown, and is cleaner and better for the car anyway and the same price and soon to be less.

Technically, yes it does.  But the neat thing about B100 is it is considered to be carbon neutral.\n\nWhat this means is that the amount of carbon released into the atmosphere is less than or equal to the carbon absorbed fromt he atmosphere by the plants.\n\nSo, while biodiesel does produce greenhouse gases.  Roughly the same amount of greenhouse gases were removed from the atmosphere by plant life to make the fuel.  And yes, if you use animal oils instead, you need to remember to follow the food chain back down to whatever ate the plant matter for the energy.\n\nKeep in mind, that certain aspects in the processing, transportation that require energy inputs that are not derived from renewable resources can potentially produce greenhouse gases as well.  Let's say that the farmer used a tractor powered by petroleum diesel.  In that case, you are slightly carbon positive since he didn't use the biodiesel to harvest the crop.

Make a small scale ethanol still.  Lots of instructions on the net.  Kind of a hot topic with all the discussion of alternative fuels.
