http://fullcoverage.yahoo.com/s/afp/unclimatefrance French green groups call for national lights-out on Feb 1 PARIS (AFP) - French environmentalists have called on citizens to switch off their lights for five minutes on February 1, coinciding with a major meeting here on climate change, to show concern about global warming. By turning off lights and also electrical gadgets that are in stand-by mode, citizens, the media and decision-makers will get the message about energy waste and the urgent need for action, the Alliance for the Planet said on Friday. The scheduled event is for 7:55 pm and 8:00 pm (1855-1900 GMT). The Alliance for the Planet is an umbrella of about 50 green associations, including the local branches of Greenpeace and WWF, and professional organisations connected with the environment. The UN's paramount scientific authority on climate change meets in Paris from January 29 to February 1 to hammer out the first volume of a long-awaited report on the state of global warming today. The Intergovernmental Panel on Climate Change (IPCC) is widely expected to declare that climate change is already on the march, many years sooner than expected, and the consequences for humans and biodiversity could be dire. The volume is to be released at a press conference on February 2.

[Biofuel] WHAT NATION DID PRESIDENT BUSH REPORT ABOUT?
What Nation Did President Bush Report About? The Muslim American Society Freedom Foundation Response to the State of the Union Address By Ibrahim Ramey Every January, the President of the United States gives a constitutionally-mandated address to the American people on the condition of the nation. This State of the Union speech is regarded as an annual scorecard not only on the economic, political, social and moral health of the country, but on the effectiveness of the national leadership of the Congress, and-more importantly-the chief executive of the United States himself. As political speeches go, President Bush's address to the nation on January 23rd was a talk full of hubris and bravado given in the context of an extraordinary national crisis. Faced with an approval rating on par with the end days of the Nixon administration, a Congress controlled for the first time in 12 years by his opposition party, and-above all- a massive national (and global) uprising against the most unpopular (and unsuccessful) U.S. military venture since the Vietnam war, Mr. Bush made an effort to rally support for a new domestic agenda and a new Iraq war strategy that is the catalyst for massive dissent from both Democrats and some leading Republicans. But I suspect that the President of the United States, even in his most optimistic and affable moments, gave a talk about a country that was not the one located between Canada and Mexico. To be fair, Mr. Bush did acknowledge some of the deep structural and economic challenges facing the nation: the crisis confronting a Social Security system going broke, the Federal budget deficit, the $18 billion in extra earmarks authorized for what is usually regarded as under-the-radar Pork Barrel spending, the crucial need for immigration law reform, and perhaps above all, the issue of affordable health insurance for the more than 45 million individuals in the nation who have none. And for all of these structural maladies, Mr. Bush promised to balance the federal budget within 5 years without raising taxes. The laundry list of other proposed initiatives was also interesting. President Bush promised to strengthen U.S. border security (presumably as one element of his immigration reform plan), create a temporary worker program for undocumented workers from other countries, expand health savings accounts, give federal tax assistance to states (like California) that create state-wide health insurance, and protect doctors from frivolous medical liability lawsuits. There was also a commitment by Mr. Bush to continue the No Child Left Behind initiative, and presumably, its back-door provision for increasing the access that military recruiters have to school records. And on the energy independence front, Mr. Bush called for expanded use of alternative (to fossil fuels) energy sources, expanded oil and gas exploration in the continental United Sates and-most radically- a cut of 20% in national gasoline consumption by 2017, and a 75% decrease in Middle East oil imports over the same time period. No specific plans for achieving this goal were mentioned But the nation in which we live is, simply put, not the one that Mr. Bush based his speech on. Here are just a few troubling realities that the speech ignored. Consider the following: Some 13% of Americans live in poverty, and the numbers remain staggering for Black, Brown, and Native people. Poor folks weren't mentioned at all by President Bush, nor did Mr. Bush offer any initiatives to combat poverty in the richest nation in the world. The closest he came to mentioning real poverty, in fact, was his shout-out to basketball star Dikembe Mutombo, originally a poor African immigrant from Congo who is not a (very rich) humanitarian and citizen of the United States. Mr. Bush claimed that the United States is now in our 41st consecutive month of job growth, with 7.2 million new jobs creates in that period. But the harsh reality (as pointed out by Senator James Webb (D-VA) in his response to the Bush speech is the gap between CEO and worker compensation has grown from 20 to 1 (in the 1970's) to 400 to I today. And wages, adjusted for taxes and inflation during that period, have actually decreased in that period. The United States remains the only advanced industrialized nation in the world without a national (not private) health care and health insurance system. The national prison population exceeds 2 million people. I heard no acknowledgement of this shameful fact, nor any suggested remedy. The U.S. international trade balance (which measures the international surplus or deficit of what a nation has, or owes the world) was a staggering $837.2 billion deficit in November of 2006. This makes the U.S., by a huge margin, the largest debtor nation in the
Re: [Biofuel] Crude fatty acid distillate
Jan, Ken, I have pushed the procedure to double the acid amount in the first phase, dewatered and went to the second phase (base base) in small batches without problem. I suggest testing in small amounts and working up a procedure that fits the product. This will take some time to do but when you get it you can get repeatbility thereafter.

[Biofuel] Reference to Real ID Act in State of the Union
I wish Palast would have referenced outright H.R.1268, Title II (the Real ID Act) in this article, but he makes the point of concern to all US citizens anyway. By the way, New Hampshire has rejected this Act (http://www.newswithviews.com/Devvy/kidd177.htm). What are you doing to get your State Reps to do same? To get Federal Reps to rescind? Also, pay attention to Palast's reference to Choice Point. This is the outsourcing of the implementation of Real ID to private industry and the total exposure of our private information without benefit of the Privacy Act (see www.unrealid.com). I'm tellin ya...GET INVOLVED or you WILL hate yourself the morning of May 11, 2008. Mike DuPree http://www.truthout.org:80/docs_2006/012407D.shtml Off the Rails: Big Oil, Big Brother Win Big in the State of the Union by Greg Palast Tuesday, 23 January, 2006 There was that tongue again. When the President lies he's got this weird nervous tick: He sticks the tip of his tongue out between his lips. Like a little boy who knows he's fibbing. Like a snake licking a rat. In his State of the Union tonight the President did his tongue thing 124 times - my kids kept count. But it wasn't all rat-licking lies. Most pundits concentrated on Iraq and wacky health insurance stuff. But that's just bubbles and blather. The real agenda is in the small stuff. The little razors in the policy apple, the nasty little pieces of policy shrapnel that whiz by between the appearances of the Presidential tongue. First, there was the announcement the regime will, give employers the tools to verify the legal status of their workers. In case you missed that one, the President is talking about creating a federal citizen profile database. There's a problem with that idea. It's against the law. The law in question is the United States Constitution. The Founding Fathers thought the government had no right to keep track on a citizen unless there is evidence they have committed, or planned to commit, a crime. But the Founding Fathers didn't imagine there were millions and billions of dollars to be made by private contractors ready to perform this KGB operation for the Department of Homeland Security, tracking each and every one of us to keep tabs on our status. These work databases will tie into voter verification databases required by the Help America Vote Act. And these will tie to the databases on citizenship and so on. Will Big Brother abuse these snoop lists? The biggest purveyor of such hit lists is Choice Point, Inc. - those characters who, before the 2000 election, helped Jeb Bush purge innocent voters as felons from Florida voter rolls. Will they abuse the new super-lists? Does Dick Cheney shoot in the woods? There were several other little IEDs (improvised execrable policy devices) planted in the State of the Union. Did you catch the one about doubling the Strategic Petroleum Reserve? If you're unfamiliar with the SPR, it is supposed to be the stash of oil we keep in case the price of crude gets too high. Well, the price of oil has been horribly high but Dick Cheney, the official who sits on the Reserve's spigots, has refused to release the oil into the market. Instead of unleashing the Reserve and busting Big Oil's price gouging Bush will double the Reserve, which will require buying three-quarters of a billion barrels of oil. This is a nice $40 billion pay-out to Big Oil from the US Treasury. Compare this to the President's health insurance plan which will be revenue neutral - that is, have a net investment of zero. But the $40 billion in loot the oilmen will get from us taxpayers for doubling the Reserve is nothing compared to the boost in the worldwide price of crude caused by this massive, mad purchase. While the Congressional audience didn't even bother polite applause for the reserve purchase plan, there's no doubt they were whooping it up in Saudi Arabia. Clearly, the state of the Saudi-Bush union is still pretty good. But why end on a cynical note? I must admit I was moved by the President's praise of Wesley Autrey, a New Yorker who, last month, threw himself on top of a man who had fallen on subway tracks - and held him between the track rails as the train passed over them. While the President properly acknowledged Autrey's courage in saving the man who fell on the subway tracks, Mr. Bush still did not explain why Dick Cheney pushed the man in the first place.
