I don't trust those bastards for one minute.
We'll have to wait and see on this then. Cash for clunkers was setup to destroy local american car dealerships so the Govt. can run the dealerships once they go belly up just like they are running GM and Chrysler.
Single molecule, one million times smaller than a grain of sand, pictured for first time

It may look like a piece of honeycomb, but this lattice-shaped image is the first ever close-up view of a single molecule.
Scientists from IBM used an atomic force microscope (AFM) to reveal the chemical bonds within a molecule.
'This is the first time that all the atoms in a molecule have been imaged,' lead researcher Leo Gross said.

The researchers focused on a single molecule of pentacene, which is commonly used in solar cells. The rectangular-shaped organic molecule is made up of 22 carbon atoms and 14 hydrogen atoms.
In the image above the hexagonal shapes of the five carbon rings are clear and even the positions of the hydrogen atoms around the carbon rings can be seen.
To give some perspective, the space between the carbon rings is only 0.14 nanometers across, which is roughly one million times smaller than the diameter of a grain of sand.

'If you think about how a doctor uses an X-ray to image bones and organs inside the human body, we are using the atomic force microscope to image the atomic structures that are the backbones of individual molecules,' said IBM researcher Gerhard Meyer.

The team from IBM Research Zurich said the results could have a huge impact of the field of nanotechnology, which seeks to understand and control some of the smallest objects known to mankind.
The AFM uses a sharp metal tip that acts like a tuning fork to measure the tiny forces between the tip and the molecule. This requires great precision as the tip moves within a nanometer of the sample.
'Above the skeleton of the molecular backbone (of the pentacene) you get a different detuning than above the surface the molecule is lying on,' Mr Gross said.
This detuning is then measured and converted into an image.
To stop the tip from absorbing the pentacene molecule, the researchers replaced the metal with a single molecule of carbon monoxide. This was found to be more stable and created weaker electrostatic attractions with the pentacene, creating a higher resolution image.

The experiment was also performed inside a high vacuum at the extremely cold temperature of -268C to avoid stray gas molecules or atomic vibrations from affecting the measurements.
'Eventually we want to investigate using molecules for molecular electronics,' Mr Gross said.
'We want to use molecules as wires or logic switches or elements.'

ACTOR Macaulay Culkin is the mystery dad of Michael Jackson's son Blanket, it was claimed last night.
The Home Alone film star is said to have donated sperm to help Jacko create his seven-year-old offspring - real name Prince Michael II - with an unknown surrogate mum.
The two celebrities became firm friends after Culkin, now 29, shot to fame as a child in the 1990 box office smash.
Mystery ... rumours surround identity of Blanket's biological dad
Rex Features
He went on to star alongside Jackson in the video for his hit song Black or White in 1991, regularly visited the singer's Neverland ranch, and took the witness stand to defend him at his 2005 child molestation trial.
One source said: "It is well known Jackson and Macaulay shared a unique bond.
"Now rumours are spreading like wildfire that Macaulay, who Jackson nicknamed Mack, is actually Blanket's biological dad."
Close pals say Jacko, who died aged 50 at his Los Angeles home in June, is not the natural dad of Blanket, his brother Michael, 12, or their 11-year-old sister Paris.
Fevered speculation gripped the US after repeated claims that a "well-known Hollywood actor" donated the sperm for Blanket.
Silence ... Macaulay Culkin
Now sources close to Jackson say the Thriller star asked Culkin for the donation to help him complete his "perfect" family.
The source added: "This isn't just chitter-chatter, even Culkin suspects he's Blanket's father.
"So many names have been mentioned as prospective dads, and this is probably the wackiest yet.
"But Jackson and Culkin were best friends. He was one of the few people Jackson really trusted and Mack never let him down.
"Really, Jackson idolised him - that's why he asked Mack to donate sperm.
"Deep down, I think he always wished Mack was his son. Creating Blanket was the next best thing."
Culkin - godfather to Jacko's other two children - has told pals he will not comment in public out of loyalty to his late pal.
Helped by fertility experts and skin specialist Dr Arnie Klein, Jackson is said to have stockpiled the ingredients to genetically engineer three "perfect" kids.
Klein is said to have given sperm for the elder two, while actor Mark Lester has claimed HE is Paris' dad.
Yesterday Jacko's brother Marlon appeared to confirm the star did not conceive his children naturally.
He said: "Those were Michael's kids - regardless of where they came from."
Jackson will be buried on Thursday in a gold-plated coffin in the Hollywood Hills.
Internet companies and civil liberties groups were alarmed this spring when a U.S. Senate bill proposed handing the White House the power to disconnect private-sector computers from the Internet.
They're not much happier about a revised version that aides to Sen. Jay Rockefeller, a West Virginia Democrat, have spent months drafting behind closed doors. CNET News has obtained a copy of the 55-page draft of S.773 (excerpt), which still appears to permit the president to seize temporary control of private-sector networks during a so-called cybersecurity emergency.
The new version would allow the president to "declare a cybersecurity emergency" relating to "non-governmental" computer networks and do what's necessary to respond to the threat. Other sections of the proposal include a federal certification program for "cybersecurity professionals," and a requirement that certain computer systems and networks in the private sector be managed by people who have been awarded that license.
"I think the redraft, while improved, remains troubling due to its vagueness," said Larry Clinton, president of the Internet Security Alliance, which counts representatives of Verizon, Verisign, Nortel, and Carnegie Mellon University on its board. "It is unclear what authority Sen. Rockefeller thinks is necessary over the private sector. Unless this is clarified, we cannot properly analyze, let alone support the bill."
Representatives of other large Internet and telecommunications companies expressed concerns about the bill in a teleconference with Rockefeller's aides this week, but were not immediately available for interviews on Thursday.
A spokesman for Rockefeller also declined to comment on the record Thursday, saying that many people were unavailable because of the summer recess. A Senate source familiar with the bill compared the president's power to take control of portions of the Internet to what President Bush did when grounding all aircraft on Sept. 11, 2001. The source said that one primary concern was the electrical grid, and what would happen if it were attacked from a broadband connection.
When Rockefeller, the chairman of the Senate Commerce committee, and Olympia Snowe (R-Maine) introduced the original bill in April, they claimed it was vital to protect national cybersecurity. "We must protect our critical infrastructure at all costs--from our water to our electricity, to banking, traffic lights and electronic health records," Rockefeller said.
The Rockefeller proposal plays out against a broader concern in Washington, D.C., about the government's role in cybersecurity. In May, President Obama acknowledged that the government is "not as prepared" as it should be to respond to disruptions and announced that a new cybersecurity coordinator position would be created inside the White House staff. Three months later, that post remains empty, one top cybersecurity aide has quit, and some wags have begun to wonder why a government that receives failing marks on cybersecurity should be trusted to instruct the private sector what to do.
Rockefeller's revised legislation seeks to reshuffle the way the federal government addresses the topic. It requires a "cybersecurity workforce plan" from every federal agency, a "dashboard" pilot project, measurements of hiring effectiveness, and the implementation of a "comprehensive national cybersecurity strategy" in six months--even though its mandatory legal review will take a year to complete.
The privacy implications of sweeping changes implemented before the legal review is finished worry Lee Tien, a senior staff attorney with the Electronic Frontier Foundation in San Francisco. "As soon as you're saying that the federal government is going to be exercising this kind of power over private networks, it's going to be a really big issue," he says.
Probably the most controversial language begins in Section 201, which permits the president to "direct the national response to the cyber threat" if necessary for "the national defense and security." The White House is supposed to engage in "periodic mapping" of private networks deemed to be critical, and those companies "shall share" requested information with the federal government. ("Cyber" is defined as anything having to do with the Internet, telecommunications, computers, or computer networks.)
"The language has changed but it doesn't contain any real additional limits," EFF's Tien says. "It simply switches the more direct and obvious language they had originally to the more ambiguous (version)...The designation of what is a critical infrastructure system or network as far as I can tell has no specific process. There's no provision for any administrative process or review. That's where the problems seem to start. And then you have the amorphous powers that go along with it."
Translation: If your company is deemed "critical," a new set of regulations kick in involving who you can hire, what information you must disclose, and when the government would exercise control over your computers or network.
The Internet Security Alliance's Clinton adds that his group is "supportive of increased federal involvement to enhance cyber security, but we believe that the wrong approach, as embodied in this bill as introduced, will be counterproductive both from an national economic and national secuity perspective."
