Source of 2MHz impulse noise signal in mains power line???
Hello
I am seeing this 2MHz impulse noise in mains power line coming out of some kind of pick-up signal from RF in air. it has five or seven cross overs and starts rising to peak at mid point and then decays in same manner making it symmetrical on both sides with resonance like trace. It comes ou

Coffee-Powered "Carpuccino" Infuriates Car Lovers, Coffee Lovers, Pun Lovers [Cars]
Point: As my fellow Jalopnik readers would agree, the thought of an au-to-MO-bile running on some coffee beans is equally laughable and insulting. Counterpoint: As my fellow coffee drinkers would agree, this is an utter disgrace to our holy bean.
Countercounterpoint: Carpuccino? Really?
A while ago we read that coffee-based biofuels were feasible. Knowing the internet as we do, we figured it was only a matter of time before somebody took that novel possibility and turned it into an absurd reality. We were right! The Carpuccino, a 1988 Volkswagen Scirocco modified to run on ground coffee, will drive 210 miles between Manchester and London in the coming weeks.
The trip will require over 150 pounds of coffee, with the car getting a mileage of roughly 1.4 miles per pound. The vehicle can hit speeds of 60mph, though the trip could take as long as ten hours, as the car has to stop every 60 miles to clean out its coffee filters (seriously).
The joke on wheels was built by the BBC1 show Bang Goes The Theory as a reminder that unconventional fuels can power vehicles. Sidebar: the Carpuccino's trip will cost up to 50 times as much as it would if it were running on gas.
All that being said, I think we can agree to set aside whatever qualms we may have with the Carpuccino in light of its similarities, aesthetic and otherwise, to Doc Brown's Mr. Fusion-equipped DeLorean from Back to the Future II.

Nvidia GTX 480 Takes On ATI HD 5870 In Benchmark Gauntlet [GraphicsCards]
Nvidia posted a preview video of the GTX 480, their eyeball-popping, face-melting Fermi graphics card that is set for release "very, very soon." It bests ATI's HD 5870 in a benchmark, though maybe not by as much as you'd hope.
As Tom Petersen, Nvidia's director of technical management, explains in the video, the GTX 480 shines when it's tessellation time. During the tessellation-intensive parts of the benchmark, Nvidia's card outpaces ATI's considerably, though at other points they're neck and neck.
It seems obvious that Nvidia would choose something that really played to the GTX 480's strengths for its video debut, so we're hoping that the card lives up to our expectations for insane speeds when it shows up in the wild and people start running their own tests. [YouTube - Thanks Doug]
EPA’s Authority to Regulate WMD is Under Fire
Anti-government Republicans, lobbyists for Big Coal, Big Oil and others attack the Environmental Protection Agency’s authority to keep our air safe and our water clean for everyone . . . . despite these attacks, the EPA’s Endangerment Finding Appears Safe for Now. It is the EPA’s job to keep us safe from pollution and greenhouse gas emissions, just like it’s the government’s job to keep us “safe from terrorism”. Burning coal and forcing other pollution on us is terrorism. Unregulated greenhouse gas emissions are weapons of mass destruction. It’s the government’s job to keep these things from killing us.
Article below is from Solve Climate.
“Environmental Protection Agency Administrator Lisa Jackson faced questions today from senators about her agency’s fiscal year 2011 budget request. Although representing only a small portion of the $10 billion total request, the ongoing battles regarding the EPA’s aim to regulate emissions of greenhouse gases from some sources took center stage.
The agency seems to be under attack from all angles when it comes to greenhouse gas regulation — House members seeking to overturn its authority to regulate greenhouse gases, senators calling for delays on regulation, states and industry groups attempting to sue. These maneuvers are drawing national attention and dividing Democrats in Congress. However, the chances of permanently preventing the EPA from regulating greenhouse gases appear slim.
“It has been three years since the Supreme Court ruled in Massachusetts v. EPA that EPA has a legal responsibility under the Clean Air Act to determine whether greenhouse gases endanger public health and welfare,” Sen. Diane Feinstein (D-Calif.) said at the hearing.
She noted that some of her colleagues on Capitol Hill are now trying to subvert the authority of that court finding. “I think this is the wrong approach,” she said. “Legislation overturning the endangerment finding countermands the Supreme Court’s landmark decision.” As directed by that court decision, the EPA found last year that greenhouse gases do endanger public health, making them eligible for regulation under the Clean Air Act.
Sen. Lisa Murkowski (R-Alaska) joined the hearing late and repeated many of the same assertions she has made in recent months that greenhouse gas regulation would be better done by Congress than by an appointed agency.
Along with a number of co-sponsors, she introduced a resolution in January that invokes the Congressional Review Act in an attempt to block the EPA’s authority. Murkowski has the support of numerous oil and gas groups, as well as agricultural groups who fear the economic impact of EPA regulation.
Two House Democrats made a parallel move last week, with Collin Peterson (D-Minn.) and Ike Skelton (D-Mo.) sponsoring an identical resolution along with Jo Ann Emerson (R-Mo.).

Space Policy: Everyone Has A Different Opinion
After 50 years of NASA, we must not leave space, Sen Hutchison
"If President Obama has his way, the U.S. will retire the space shuttle program later this year, just as the International Space Station is finally complete and without a viable alternative to take its place. America has spent billions of dollars building and maintaining the space station. Now that it is complete, the Obama budget plan ensures that we will no longer have easy access to it."
NASA's plan B(olden), Nature
"America's space agency seems to be in a right old state at the moment. NASA was already on the back foot after President Obama announced the cancellation of its planned replacement for the Space Shuttle (which should normally be prefixed with the word 'aging' or 'antiquated'). Now it seems to be putting out mixed messages about using private companies to get American's into space instead."
NASA's varied missions worthy of full budget support, William S. Smith Jr, Washington Post
"The goals of NASA's space science program are unequivocal and far-reaching. These missions rewrite textbooks regularly. NASA deserves great credit for its sustained commitment to space science. While there are a handful of celestial bodies accessible to human visitation, our scientific horizons are limitless. NASA's budget request for fiscal 2011 should be strongly supported."
Building a technology showcase, interview with Wallace Wood, National Space & Technology Association, Houston Chronicle
"What I'm looking to do is to hold a world-class conference that includes the public. That goes beyond just mere businesses coming together. I want to bring the public into it. In my mind you have this industry that's designing the future. At the end of the day, we're all consumers. That industry needs the consumer to keep it viable and strong. I think that a public that is included and informed in the process makes for an accountable industry."
The Body of a Tank, the Brain of an Android [Android]
We've come across plenty of robots that were controlled by phones before, but usually those phones were being controlled by human hands. Some California hackers, however, are building bots that harness Android for their robo-brainpower.
Their first creation, the TruckBot, uses a HTC G1 as a brain and has a chassis that they made for $30 in parts. It's not too advanced yet—it can use the phone's compass to head in a particular direction—but they're working on incorporating the bot more fully with the phone and the Android software. Some ideas they're kicking around that wouldn't be possible with a dinky Arduino brain: face and voice recognition and location awareness.
If you're interested in putting together a Cellbot of your own—can you even conceive of a cooler dock for your Android phone? Or a better use for your G1?—the team's development blog has some more information. The possibilities here are manifold; mad scientists, feel free to share your Android-bot schemes in the comments.
