New Wonder Weed to Fuel Cars? 484
Hugh Pickens writes "Jatropha, an ugly, fast-growing and poisonous weed that has been used as a remedy for constipation, may someday power your car. The plant, resilient to pests and resistant to drought, produces seeds with up to 40 per cent oil content that when crushed can be burned in a diesel car while the residue can be processed into biomass for power plants. Although jatropha has been used for decades by farmers in Africa as a living fence because its smell and taste repel grazing animals, the New York Times reports that jatropha may replace biofuels like ethanol that require large amounts of water, fertilizer, and energy, making their environmental benefits limited. Jatropha requires no pesticides, little water other than rain and no fertilizer beyond the nutrient-rich seed cake left after oil is pressed from its nuts. Poor farmers living close to the equator are planting jatropha on millions of acres spurred on by big oil companies like British Petroleum that are investing in jatropha cultivation."

To meet the gasoline consumption needs of the USA would require about 9 billion acres at the above rate. This is about 4 times the size of the USA, including Alaska, and thus is probably not a workable plan.

Hemp seed yields 15 gallons per acre.
As much as I think hemp is a valuable crop - which it certainly is - the jatropha seems like a better choice for biofuel production. Over 12 times better, in fact.

Some numbers for comparison. (Score:5, Informative)
For comparison, corn produces about 0.15 tonnes per hectare, hemp about 0.30 tonnes, and canola (rapeseed) only 1.0 tonnes.
So if he's right, it's a very good oil producer, on the order of much harder to grow oil producers like avocado (2.2) or coconut (2.3).
Still 1/5 of algae though.

As for the sun and water, well, they can only do so much given that neither one is a supply of the nutrients needed to keep the soil healthy.

The court there found that it was not a matter of his fields being contaminated, but of him using Roundup to kill the regular plants before harvesting "his" seed . . .

One of the programs they are pushing is for farmer to plant Jatropha on the borders of other crops in the fields, turns out the bulls that wonder freely in India will not go near the stuff, so a row of these trees keeps them out of the farmers crops.
Very interesting work.
I brought back a hand full of seeds with me, and planted them, but they didn't take, maybe the Airport X-ray scanners killed them.
Anyhow;
Jatropha is related to the Castor bean plan that is responsible that the neurotoxin ricin is derived from.
It also have a toxin called curcin that is similar to ricin.
I don't know if burning Jatropha oil release this curcin toxin into the air?
But apparently when it's pressed to get the Oil out, the curcin remains in the "Cake" this is the solids left behind after the seeds have all the oils squeezed out.
From: http://www.intox.org/databank/documents/plant/jatropha/jhast.htm [intox.org]
-------------
2.5 Poisonous parts
All parts are considered toxic but in particular the seeds.
2.6 Main toxins
Contains a purgative oil and a phytotoxin or toxalbumin
(curcin) similar to ricin in Ricinis.
------------
Apparently Canola oil (Short for Canadian Oil)is a genetically modified Rape seed (in the mustard family) with the toxins removed.
So if Jatropha had it's toxins removed through genetic modification it could also be a valuable food product.
Later in 2006 I moved to Santa Barbara and it turns out the first company in the US to start producing Jatropha Oils and Bio-Diesel was here in Santa Barbara. http://www.biodieselindustries.com/ [biodieselindustries.com] They were even doing a project with the local High School to grow Jatropha.
Also Jatropha Oil is being use on the Indian Railways for some time too. I guess the plan is to plant Jatropha trees along the tracks, it keep the animals off the tracks and also since labor is very cheap, they would use the same trains to harvest the tree's for oil to power the trains.
One of the projects I was thinking of was to develop an engine optimized to run on Jatropha Oil.
More importantly these three wheeled auto-rickshaws (called Tuck Tucks in Thailand) all use the exact same engines, so the idea is to make a direct drop in engine for rickshaws. The rickshaws there are Two-stroke gas engines and are a major source of pollution there spewing clouds of choking soot behind them. Maybe some day.

From your own source:
While the origin of the plants on Schmeisers farm remains unclear, the trial judge found that "none of the suggested sources [proposed by Schmeiser] could reasonably explain the concentration or extent of Roundup Ready canola of a commercial quality" ultimately present in Schmeiser's crop.
In this case, the appellants' saving and planting seed, then harvesting and selling plants that contained the patented cells and genes appears, on a common sense view, to constitute "utilization" of the patented material for production and advantage, within the meaning of s. 42.
By cultivating a plant containing the patented gene and composed of the patented cells without license, the appellants deprived the respondents of the full enjoyment of the monopoly. The appellants' involvement with the disputed canola was also clearly commercial in nature.
Second, the appellants did not provide sufficient evidence to rebut the presumption of use.
The appellants actively cultivated Roundup Ready Canola as part of their business operations. In light of all of the relevant considerations, the appellants used the patented genes and cells, and infringement is established.
But wait, it gets better. From reading your post (and the similar ones in oh-so-many-threads, one might think that this farmer that deliberately selected for the monsanto genes had been wiped out.
Now I'll switch to being a *real* wet blanket. Again, from the Canadian Supreme Court:
1. The fammrer was not an innocent who happened to have a few stray plants with the Monsanto seed contaminate his crops. Rather, after litigation, the court found that he deliberately selected for the monsanto plants, killing his other crops to generate seed that was 95-98% monsanto.
2. He still paid no damages.
But, hey, don't let the facts get in the way of a good political screed . . .
