Permalink |Researchers at the University of Michigan have discovered a new property of light that allows them to harness the magnetic attributes of light. Electromagnetism being a classically unified force, the relationship between light and magnetism is well known, but the magnetic component was thought to be weak enough that it could be safely ignored. Stephen Rand, a professor at UMich, said of this, "You could stare at the equations of motion all day and you will not see this possibility. We've all been taught that this doesn't happen. It's a very odd interaction. That's why it's been overlooked for more than 100 years." Scientists are so awesome.
"This could lead to a new kind of solar cell without semiconductors and without absorption to produce charge separation," Rand said. "In solar cells, the light goes into a material, gets absorbed and creates heat. Here, we expect to have a very low heat load. Instead of the light being absorbed, energy is stored in the magnetic moment. Intense magnetization can be induced by intense light and then it is ultimately capable of providing a capacitive power source."
Right now solar power cells are expensive and somewhat dirty to produce as they are made from semiconducting wafers. This will allow solar collection apparatus to be constructed from much more common materials. This could be the breakthrough that makes solar power cheap enough for widespread adoption.
"To manufacture modern solar cells, you have to do extensive semiconductor processing," Fisher, a PhD student involved in the research, said. "All we would need are lenses to focus the light and a fiber to guide it. Glass works for both. It's already made in bulk, and it doesn't require as much processing. Transparent ceramics might be even better."
This could be a major breakthrough, focusing the light into a usable beam and creating voltage potential with cheaper materials is going to be the ticket to ending the world's dependence on fossil fuels once and for all. There isn't going to be a magic bullet that'll solve all of these problems, solar power is a major component. Efficient energy storage solutions like flywheel energy storage systems are also going to be an important part in leveling out the grid.

Permalink |It's hard to believe that here in the US we are very close to being done with another school year. That means that you will need to find gifts for all those graduates you know and if you want something cool that won't break the bank here it is.
This is a metal pen with an integrated level, screwdriver and ruler. The body of the pen is marked in inches. You can see the bubble level window the little window and the screwdriver has both a small flat tip and a Philips bit under the cap on top.
The pen is cheap too with a price of $14.95 each. You know that this pen will get lots of use; I always need a screwdriver at odd times and never have one. There is no word on if the pen has black or blue ink color.

PermalinkTo develop better defenses against such attacks, the contractor received $150,000 from the Air Force to test-fire microwaves at military computers. No word on whether said defenses involve generous use of tin foil."Unlike lasers, HPM beams don't need a lot of accuracy. With a fan [of HPM energy] you can target 10-30 small boats. If you can knock out 50-75% of the engines in a swarm, you can then concentrate on the remainder with lasers or kinetic [cannons]."

This has to be a hoax, so take this with a grain of salt the size of Everest. According to Gizmodo a file has been spied on the FBI Vault website where old documents are put for the public to peruse that is a report on the infamous 1950 crash in Roswell, New Mexico that some believe was a UFO crash. The government has long maintained the crash was a weather balloon.
The document in question is a memo by an FBI agent named Guy Hottel that was working the original case and recounts what a so-called "investigator for the Air Forces" told him about the crash. The Air Force investigators name is blacked out in the memo. The reminder of the memo is an interesting read and conspiracy theorists will be riled up for sure.
The memo goes on to say that the Air Force found a crashed saucer shaped flying machine about 50-feet in diameter and that the investigator believed that the high-powered military radar in the area interfered with the UFO's controlling mechanisms. This is a crazy document to turn up on the FBI website for sure. Check out the document here.

Andy Rubin, the man who shepherded Android into the powerhouse OS it is today has been promoted to Senior Vice President for Google. The move came as Larry Page began to streamline the executive structure to make it leaner, meaner, and thinking more like the start-up it began as. Rubin, made headlines recently by dispelling rumors that Android would be getting locked down as an OS, stating that Google is committed to Android as an open source platform. And Rubin's promotion to one of seven senior vice presidents reporting directly to Page means that Google's commitment to Android is at the heart of their corporate governance right behind search.
The promotions, made by Page this week, moves engineers at the head of the company, which Page hopes will streamline communication and help spark Google, which has been plateaued of late. The promotions came from Engineering, where Rubin had been developing Android and turning it into a serious competitor to Apple's iOS, YouTube – headed by Salar Kamangar, Chrome Browser VP, and Sundar Pichai – in charge of Google's Social Networking initiatives. The other Senior VPs include advertising lead Susan Wojcicki; Jeff Huber, an engineering executive; and Alan Eustace, who led engineering and research, who will head the search division. Of the seven VPs, five are software engineers, signaling that Page is wanting to concentrate of innovation.
But that's not all. In a move that is sure to catch the eye of execs over at Facebook and Twitter, Page has also tied 25% of performance bonuses to the success of Google's social networking projects. The plan is to head off Facebook's efforts to get the upper hand in ad dollars by adding a social "layer" atop Google's products, including Web search, Picasa and YouTube, And while the social aspect is the rage for users who spend a lot of time online, the concern over privacy has also been a challenge to Facebook and other companies. Google's reach echo's the words of former CEO Eric Schmidt who said that people should get over their worries about privacy. Should Google create a social link to all their products, it'll be interesting to see if privacy is protected, or if the assumption is that users will have to "get over it."

Permalink |The best April fools prank I ever got up to was when I was nine and I loaded up a few cigarettes in my dad's pack cigarette loads. He happened to pull out one of the loaded cigarettes while we were driving down the street with me next to him. I had pushed the things so far down into the cigarette that he had to smoke most of it before it blew. Ashes went everywhere and he almost crashed the car. I spent the next week grounded. It was worth it.
A geek pranked his wife on April 1 and it was a good one. He got a hold of her phone while she was not around and changed his name in her contact list to AP Mobile to spoof her favorite news app. He then sent a text to her that said the Pentagon had confirmed the Roswell Crash as being alien.
It then went on to say that Obama would address the nation about UFOs at 1PM. Pete the prankster says that her jaw hit the floor. I bet it did, I wonder how long he let her stew before telling her it was a joke. I also wonder how long he has to sleep on the couch as a result.
