Here comes the bail bond chaser pretending to be an intellectual.

jatropha is a plant that grows in tropical environs. Hemp can grow in northern climes. Hemp is very hardy. It's a great source of fiber for a multitude of purposes including clothing. The seeds can be used for biodiesel fuel as well. Its cellulosic fiber can be also converted to ethanol using an enzymatic reaction.

Fuel

Biodiesel sampleBiofuels such as biodiesel and alcohol fuel can be made from the oils in hemp seeds and stalks, and the fermentation of the plant as a whole, respectively. The energy from hemp may be high based on acreage or weight, but can be low based on the volume of the light weight harvested hemp.[citation needed] It does, however, produce more energy per acre per year than corn, sugar, flax, or any other crop currently grown for ethanol or biodiesel.[citation needed]

LIAR. Germany already is way ahead of us on plug-in cars fueled by solar and wind receivers on the rooves, and we who live in hot (or windy) climates have it easy. We simply have no need for gasoline or coal whatsoever. They are polluting fuels of the past and have brought us nothing but disaster in the end. If you support the li4es of the oil-coal lobbies, you are indeed a traitor to your country, and your world as a whole. Since we don't need them, why support them? They are deadly toxic sources run by very corrupt greedy men with lobbyists who have bought off 90% of the GOP.

re:"Why would anyone use hemp to convert to fuel when there are far better plants such as such as jatropha which produce seeds that are 40% oil."

So what's the answer to your question?

Toxic jatropha not magic biofuel crop, experts warn
Wed Sep 12, 2007 10:44am BST



GUANGZHOU, China, Sept 12 (Reuters) - Oilseed plant jatropha does not offer an easy answer to biofuels problems as some countries hope, because it can be toxic and yields are unreliable, experts and industry officials warned on Wednesday.

The woody plant can grow on barren, marginal land, and so is increasingly popular in countries such as China that are keen to boost biofuels output but nervous about food security.

But its nuts and leaves are toxic, requiring careful handling by farmers and at crushing plants, said experts at an oils and fats conference.

In addition, it is a labour-intensive crop as each fruit ripens at a different time and needs to be harvested separately. Its productivity is also low and has yet to be stabilised.

"M. R. Chandran, adviser to the Roundtable on Sustainable Palm Oil, told Reuters it would take five years of intensive research before jatropha could achieve productivity that would make its cultivation economically viable. The oil yield of the plant, originating in Africa and still largely a wild species, is less than 2 tonnes per hectare with large swings from year to year.

An engineer specialising in oil and fat processing plants, including for biodiesel production, said special facilities were needed for crushing jatropha nuts as they could produce a toxic vapour.

The engineer, who declined to be named, said his company hoped to seal a deal with a private investor to build one of the world's first large-scale jatropha-based biodiesel plants in China's southern province of Yunnan before the end of this year."
