April 16, 2008The Diesel Tree: Grow Your Own Oil
April 7, 2008[ From Treehugger ]
You’d have thought that with 20,000 stories in our archives we might’ve at least mentioned this in passing. But it seems not. Australian farmers in the wet tropical region of North Queensland have bought over 20,000 of these so-called diesel trees. The intention is that in 15 or so years they’ll have their very own oil mine growing on their farmland.
Because, the Brazilian Copaifera langsdorfii, to use its botanical name, can be tapped not unlike a rubber tree, but instead of yielding rubbery latex it gives up a natural diesel. According to the nurseryman selling the trees, one hectare will yield about 12,000 litres annually. *
Once filtered—no complex refining required, apparently—it can be placed straight into a diesel tractor or truck. We read that a single Copaifera langsdorfii will continue to produce fuel oil for an impressive 70 years, with the only negative being that its particular form of diesel needs to be used within three months of extraction.
Oddly this is not news. The Center for New Crops & Plant Products, at Purdue University reports that it was first reported to the western world as far back as 1625. They observe reports from 1979 saying “Natives … drill a 5 centimeter hole into the 1-meter thick trunk and put a bung into it. Every 6 months or so, they remove the bung and collect 15 to 20 liters of the hydrocarbon.” The UN’s Food and Agriculture Organisation noted in a paper at the Eleventh world forestry congress back in 1997 on the topic of tree oil for cars that “… the potential of other alternatives such as the Amazon Copaifera langsdorfii need to be investigated.”
Copaifera langsdorfii can grow trunks 30 metres tall and store the oil in their unusual capilliary structure. The above image is a transverse section of the tree’s cells.
However Purdue University record that “An acre of 100 mature trees might thus be able to produce 25 barrels of fuel per year.”

“Leadership” folly
April 2, 2008Upon reading this depressing article in the Washington Post, I had to ask a few questions:
1. Since when did a fence ever stop illegal immigrants?
2. I wonder who received the financial kickback from the ‘fence company’?
3. When will governments and so-called “leaders” (leaders into darkness, I reckon) wake up to the fact that the earth is their livelihood and there is only so much it can take before it loses the ability to support us in the manner many are apparently accustomed?
Environmental Laws to Be Waived for Fence

Lawmaker Accuses Administration of Abusing Authority to Build Barrier at Mexican Border
The Bush administration will waive more than 30 environmental and land-management laws in order to finish building 470 miles of border fence in the Southwest by the end of the year, officials said yesterday.
The move, permitted under an exemption granted by Congress, will be the most sweeping use of the administration’s waiver authority since it started building the fence to curb illegal immigration. It will affect environmentally sensitive areas in California, Arizona, New Mexico and Texas.
In a statement, Secretary of Homeland Security Michael Chertoff said the agency has no choice but to bypass the standard environment reviews required of the federal government. “Criminal activity at the border does not stop for endless debate or protracted litigation,” Chertoff said. “Congress and the American public have been adamant that they want and expect border security. We’re serious about delivering it, and these waivers will enable important security projects to keep moving forward. At the same time, we value the need for public input on any potential impact of our border infrastructure plans on the environment — and we will continue to solicit it.”
However, Rep. Bennie Thompson (D-Miss.), who chairs the House Homeland Security Committee, said the administration has exceeded what Congress intended when it granted the department added flexibility under the Real ID Act. “Today’s waiver represents an extreme abuse of authority,” he said in a statement. “Waiver authority should only be used as a last resort, not simply because the Department has failed to get the job done through the normal process. It was meant to be an exception, not the rule.”
The use of the waiver authority means that the agency will not have to conduct detailed reviews of how the fence’s components will affect wildlife, water quality and vegetation in the area where it is to be built. Some environmentalists have complained that the fence will disrupt the migrations of various species, including imperiled ones such as jaguars.
Two environmental advocacy organizations, Defenders of Wildlife and the Sierra Club, have filed a petition asking the Supreme Court to review the constitutionality of the waiver provision. Rodger Schlickeisen, Defenders of Wildlife’s president, said yesterday’s announcement bolsters his group’s argument.
“Thanks to this action by the Bush administration, the border is in a sense more lawless now than when Americans first started moving West,” Schlickeisen said in a statement. “Laws ensuring clean water and clean air for us and our children — dismissed. Laws protecting wildlife, land, rivers, streams and places of cultural significance — just a bother to the Bush administration. Laws giving American citizens a voice in the process — gone. Clearly this is out of control.”
James L. Connaughton, who chairs the White House Council on Environmental Quality, said his aides have been working with the Department of Homeland Security to assess the environmental impact of the fence construction even if it does not meet the strict requirements of the law.
In a telephone interview yesterday, Connaughton said the administration is trying “to comply to the extent possible while meeting the deadline” for the fence’s construction.
