Barnes & Noble Lowers Tablet Prices to Box Out Competition

Barnes & Noble, in an effort to meet the growing market demands as well as box out some competition, has lowered the prices of all three of its tablets this week.

The newest Nook Tablet, which has 16GB of memory, now costs $199, down $50 from its original price. The prices of the 8GB Nook and Nook Color have also been reduced.

Experts are not surprised by the bookstore’s move. Schools and colleges are preparing for another year and demand for hand-held computers and other media devices grows rapidly as students add them to their supply lists.

Forrester Research’s Sarah Rotman Epps explained:

“Barnes & Noble is competing with the Google Inc. Nexus, the Amazon.com Inc. Kindle Fire, and in the future there could be a smaller iPad from Apple Inc. They have to stay competitive with their pricing as well as clear out old inventory to make way for new products.”

Epps added that the company is currently working on a ‘product cycle,’ which includes offers of new tablets for the holiday gift season as well as e-readers for events like graduation or Father’s Day.

“You have to give them credit because they’ve become a consumer-electronics company, where just a few years ago they were just a book company. Barnes & Noble is on a rapid product cycle, and you need to sacrifice pricing on old products and constantly refresh. They’re competing with the Goliaths.”

South Korean Builds Homemade Satellite to Inspire Others to Pursue Their Dreams

In an effort to encourage people to pursue their dreams, 34-year-old Song Hojun built a satellite in his basement.

The South Korean spent years collecting pieces from back-alley electronic stores to create his $500 OpenSat, which will be launched into space later this year.

“Making a satellite is no more difficult than making a cellphone,” Hojun claims. “I believe that not just a satellite, but anything can be made with the help of the internet and social platforms. I chose a satellite to show that symbolically.”

Though universities and other science-focused organizations have launched ‘homemade’ satellites in the past, Hojun believes his is the first that was completely designed and funded by an individual.

Hojun is known to combine art and technology, seeing as he is an engineering student in university. He was inspired to begin his Open Satellite Initiative, which incorporates the two fields, after working for a private satellite company. He explained that the fact that he was just one guy actually helped him throughout the process.

“I’m just an individual, not someone working for big universities, corporations or armies, so they open up to me and easily give out information,” he said of the space professionals that he contacted around the world.

Hojun’s satellite will be launched, with the help of technology company NovaNano, from Kazakhstan in December.

Forget Tweets- Meet ‘Chirp’!

A new app called ‘Chirp’, developed by Animal Systems, enables iPhones and iPads to share images through a short burst of sound. Animal Systems is a spin off of the computer science department of University College London, and the lead developer on the app was Daniel Jones.

Jones explains that the biggest challenge was “making sure that we had a system that would work equally well in environments that are particularly noisy. So, in  a pub, or on a bus… to be able to work in all sorts of different real-world places.”

Jones adds that the capability is similar to Bluetooth- one advantage though is that once the app is installed, devices do not need to be paired in order for the transfer to work. Though the technology is only available for iPhones and iPads today, Jones and Animal Systems hope to expand the program to radios, tvs and PA systems. Any device capable of sound should be able to ‘read’ a Chirp.

Green Technology and Solar Panel Solutions

Green, environmentally friendly technology is all the rage as global warming concerns heighten and people begin taking responsibility for the health of our home planet.

One of the most popular topics in the sector today is alternative energy; the possibilities, potentials, hardships and numerous advantages. Some progress has even been made, with experts exploring the options of wind power, water power, and of course, solar energy. One of the popular approaches to harnessing the sun’s energy is through the use of solar panels.

In an article discussing new science discoveries, WebEcoist.com presents the two main downsides of solar panels, as well as some new, innovative solutions:

  • Solar panels are typically inflexible and brittle, limiting the versatility of their application. But what if you could just spray solar cells onto any surface and collect energy from the sun? The technology is currently being produced at the University of Texas, where researchers are using nanoparticle “inks” full of tiny photovoltaics made from copper indium gallium selenide (CIGS). These particles are 10,000 times thinner than a strand of human hair. Currently, the photovoltaic ink only converts 1% of the sunlight that reaches it into electricity, but the researchers expect to increase the production and have the technology on the market within three to five years.
  • For homeowners that can afford them, the biggest reason not to install rooftop solar panels is often aesthetics: they’re just plain ugly.  But, unobtrusive solar panels that blend in nearly effortlessly with the architecture of a home are now within reach. Dow Solar recently announced a new generation of building-integrated photovoltaic (BIPV) roof shingles, and SRS Energy has created powerful solar panels that look just like standard clay roof tiles.

First Flying Car Passes Flight Test

Terrafugia Inc. has managed to turn every inventor’s dream into reality by completing a test flight of its flying car called the Transition.

The car has two seats and four wheels, as well as foldable wings that allow the vehicle to drive on a road. Unlike commercial jets, the car was flown at 1,400 feet for nearly ten minutes last month. The development brings the Massachusettss-based company closer to its goal of selling the flying car before 2013.

Though the car will be sold for $279,000, over one hundred people have put down $10,000 deposits for vehicles. The number of customers will likely increase when the car is officially introduced to the public at the New York Auto Show this week.

Robert Mann explained that the flying car has been the dream of American inventors since the 1930s. He believes that Terrafugia’s creation is the closest a company has ever come to developing a flying car, though it will still need a runway for takeoff.

Another common condition associated with valsonindia.com buy cialis from india alcoholism is Erectile Dysfunction (ED) or impotence issue.

Mann added that the government has already granted permission for the use of special glass, tires and other materials in order to lower the weight of the vehicle. The Transition is also exempt from the law requiring vehicles to have electronic stability control, which adds six pounds to the total weight. The car is undergoing tests to make sure it meets the federal safety standards.

According to Mann, the most profitable industry for the Transition will likely be the western U.S. states.

Has Man Learned the Secret of Flight?

Jarno Smeets and the Human BirdwingsJarno Smeets, a Dutch engineer, has unleashed a video onto the public, sparking controversy, awe and skepticism across the globe.

The video, which showcases his ‘Human Birdwings’ project, is supposedly shot from a camera attached to Smeets’ helmet while he successfully takes off at a park in Hague. The 200-foot wings are part of Smeets’ invention, which he claims is the first to allow a human to fly in a way similar to that of a bird, with neither rotors nor jets. Instead, the contraption uses motion sensors from Nintendo Wii and an accelerometer from an HTC Wildfire S smartphone to ‘amplify’ the flapping motion of his arms, and then transfers it to small motors on the wings. This technology allows Smeets to flap wings much larger than his body would otherwise be capable of lifting.

Though the engineering of the wings is in fact plausible, many of the video’s viewers were quick to dismiss it as a fake. How did the engineer know it would take exactly 14 videos until a successful takeoff? Some have questioned the video’s legitimacy based on the physics involved, while others have analyzed the clear differences between the Human Birdwings and the natural wings and flapping motions of birds today, such as rotation and the specific angling of the wings before and during flight.

With the changing civilizations cheap brand cialis and modernization, the number of people has already benefited from consulting their professional help. Some cases where this problem arises are- When he is going through a heart disease or probably blood pressure issues, if your wounded viagra levitra or have an injury, problems with the liver, stomach ulcer, having an allergic reaction, etc. This drug is a well tolerated structure and helps man to redeem impotency without cialis cheap generic any complications. This kind purchase of viagra of mouth safeguard serves the additional benefit associated with this gel is that is an all-natural product that too it is meant for external application.
One interesting observation discussed the placement of Smeets’ legs. In general, the legs of a bird are thin, small and remarkably lightweight. Human legs are monstrous in comparison, and so would inevitably dangle beneath the torso, perpendicular to the floating body. However, the video clearly shows the legs rising to line up with the body at 38 seconds. The strength needed to hold the legs in this position without breaking the spine, especially when the body is suspended from the upper back, is incredible and therefore highly unlikely here. However, further scrutiny implies there might be a small sail placed between the feet which buoys the legs during flight.

An interesting analysis of the camera motion in the video provides another important perspective on the invention’s authenticity. Though the detailed study does not prove it is legitimate or a hoax, it does prove that the camera work is genuine and not a compilation of a number of processed clips.
