Samsung to launch first smartphone without a bezel by Q3

According to translated report from MK News (via TNW), Samsung is in development on the industry’s first smartphone without a bezel. Referred to in the report as the “Galaxy B,” the device will apparently have no bezel on three sides of the display with just a small bezel at the top to hold the earpiece and camera. The device will apparently pack a large AMOLED display, but there is no specific mention of Android or other specs. We most likely will not see much from Samsung at Mobile World Congress later this month, because the company confirmed it would not hold press events. However, some are speculating the “Galaxy B” codename could eventually be the Galaxy S III. The report said Samsung plans to launch the bezel-free smartphone during the second or third quarter of 2012.

AQUA TEK S – the first waterproof, ruggedized, solar-powered battery case for iPhone

If you're hoping to attract investors to get yet another iPhone case to an already crowded market, it had better do more than just protect a phone from bumps and scrapes. Snow Lizard Products is giving itself the best possible chance of raising funds for its new AQUA TEK S case for iPhone 4 and 4S with an offering that not only boasts ruggedized protection, but also includes a solar panel, built in battery, and is waterproof up to 20 ft (6 m). Aimed at outdoorsy types who want to stay connected when heading off the beaten track, the case features a waterproof and dirt resistant poly-carbonate ruggedized casing that packs its own built-in battery to extend the life of the the iPhone. The company is still investigating the best battery to fit the form factor so the capacity of the unit hasn't yet been finalized, but it will be able to recharge from the power of the Sun via the solar panel built into the rear of the case. The encased iPhone can also be recharg...

New record energy efficiency for artificial photosynthesis

As the world moves towards developing new avenues of renewable energy, the efficiencies of producing fuels such as hydrogen must increase to the point that they rival or exceed those of conventional energy sources to make them a viable alternative. Now researchers at Monash University in Melbourne claim to have created a solar-powered device that produces hydrogen at a world-record 22 percent efficiency, which is a significant step towards making cheap, efficient hydrogen production a reality. Efficiency records for solar-powered hydrogen production have continued to rise over the years, and much more rapidly as the technology and techniques improve. Even as late as December last year Gizmag reported a solar-driven hydrogen record efficiency at the time of just 12.3 percent, so this new record shows a very healthy 10 percent improvement on that and beats out the previous record of 18 percent. Splitting water using electricity to produce hydrogen and oxygen has been a...

Nanogenerator that harnesses energy from tires friction

Engineers from the University of Wisconsin-Madison along with a collaborator from China have created a new nanogenerator that harnesses energy from the friction caused by rolling tires. Xudong Wang has developed a new way to harvest energy from rolling tires (Credit: The College of Engineering) As a novel energy reusing method, the nanogenerator could be potentially used by auto-mobile manufacturers to improve the efficiency of their vehicles. The first of its kind, nanogenerator was published in the Nano Energy journal. The research was carried out by Xudong Wang, the Harvey D. Spangler fellow and an associate professor of materials science and engineering at UW-Madison, and his PhD student Yanchao Mao for about one year. Based on the triboelectric effect, the nanogenerator can harness energy resulting from the electric potential created between a vehicle's wheels and the pavement. The triboelectric effect is the electric charge generated due to the rubbing...
