A man harvests fruits of the Jatropha tree in Taabo, Ivory Coast. Jatropha, which is grown in many parts of the world, has fallen from favor as a diesel fuel substitute.

Nice comment.

As a farm edge weed it would mop up the excess nitro and provide ready fuel for the tractor.

Not a good idea in plantations in a hungry world.

"From Congress to The Colbert Report, people are talking about the Midwestern drought and debating whether it makes sense to convert the country's shrinking corn supplies into ethanol to power our cars."

Of course it doesn't in a midwest drought. But the optimal thing to do is to import sugar from sugar cane (dropping the tariffs). Using ethanol at 10%- 15% in gasoline still makes sense, but you have to adapt the feedstock to the agricultural output.

"It's the latest installment of the long-running food v. fuel battle."

"It's an extremely hardy plant, and grows in places where most plants would die. "If you grow it on sandy soil, with not too many nutrients, and with dry periods, the plant miraculously survives," says Franken"

So what exactly is the 'food vs fuel" comment regarding???

Typical of the mindless ideology driven baloney that the oil companies promote. It contradicts itself as well as using claims that are totally irrelevant such as the plants leaves being poisonous? So what? You don't eat the leaves!!

It makes no sense pre-drought or post-drought. The use of 10% ethanol in gasoline easily can decrease mpg by 5-10%! With careful years long records, our 3 cars decreased their mpg by 5%, 7% & 8+% using 10% ethanol blends. Many people indicate mpg decreases in excess of 10%. Ethanol needs hi compression engines to gain its full efficiency, such as in Indy car engines. A number of drivers, running turbo charged gasoline engines, indicate a considerable decrease in mpg. Gasoline engines, using 100% gasoline instead of 10% ethanol blends, are smoother, quieter, have greater low end torque & better mpg.

Use 100% gasoline in gasoline engines. Use 100% ethanol for ethanol engines. This statement makes more sense than your statement.

Somehow, the ethanol industry has twisted the idea that crops should be use to feed engines, instead of people, thereby pitting engines against the poorest of our people. Somehow, the ethanol industry has conned america into thinking that ethanol is best for engines designed, & produced to use gasoline.

Use 100% gasoline instead of 10% ethanol blends.

"LessHypeMoreFact".. ..... You believe in science. Then, believe in science that designed & developed gasoline engines to use 100% ethanol-free gasoline for its best efficiency, longevity & proper operation.

Ethanol is a looser in cars.....just another ripoff.

Jatropha is actually biodiesel, works rather well as has typical oils content similar to usual diesel mix with little readjustment similar to castor 2 stroke oil. Probably also induces vomiting if siphoned out of the tank (as with castor oil).

As for Food Vs fuel...

Best way is to use1 1st harvest or dry store for food, or seed for next crop, and old storage with mould, smut or mouse crap for biofuel (will also probably deter tank siphoning @ that point too). Result of low quality brewing mix will be high concentration of Methanol, carboxylic acids ketones, aldehydes etc; (so not for drinking).

Doing things that way will alleviate problems and at least be more effiocient. Brewing plants will probably not smell of tomato soup as result but will be far better downwind than the legally protected meat rendering sector!

Have a nice day: Ag

Oops: almost forgot. Jatropha is a waste of time in the bulk of the USA as it will not survive the winter and is either a shrub or biennial. Will only be worthwhile in tex-mex coastal area of florida & delta magins.

Ah, so a theme emerges. What is your fascination with ladyboys? I am neither Thai nor a ladyboy. My sexual orientation does not run in that direction and I'm not that pretty.

It is interesting that when you think about Thailand your thoughts run to ladyboys. It is very revealing as to your proclivities. If you don't mind me asking, does Mrs. Earthling have a penis?

I wrote about Jatropha as the second issue in my post. The one about 'food vs fuel' where the article itself contradicted itself by pointing out that jatropha grew in conditions that were totally unsuitable to food production and therefore did NOT compete with food.

Interesting but irrelevant. I can't remember the last time I siphoned my tank for ANY reason.

I have no idea what that is about. Jatropha seeds are crushed and the oils extracted. No muss. No fuss. No mildew.

So don't grow it in the USA. Lots of land that is suitable. Lot of it is owned by US interests.

The problem is bioethanol from u.s. corn. Jatropha cultivation is possible where it's not possible to grow food.
It will give poors a lot of job, so food!
