Japanese team invents device that silences the overly-wordy

By

For those who don't suffer the talkative gladly, a pair of Japanese researchers may have come up with just the thing - a portable device that can painlessly jam a person's speech from up to 30 meters (98 ft) away. Ingeniously dubbed the "SpeechJammer," you aim it like a gun and, if it's anywhere near as effective as the Delayed Auditory Feedback exhibit I tried at my local science museum, it works like a charm.
The inventors, Kazutaka Kurihara with the National Institute of Advanced Industrial Science and Technology, and Ochanomizu University's Koji Tsukada, explained that their prototype creation works by recording the offending speech with a directional microphone, adding a 0.2-second delay, and firing it right back at the run-on talker with a directional speaker. Our brains need instant feedback to continue governing speech properly - mess with that synchrony and, as I experienced at San Francisco's Exploratorium, your jabbering soon stammers to a halt.
"We live in the twenty-first century, when it is said that communication is the most important means of resolving conflicts," Kurihara and Tsukuda diplomatically explained in a recent paper describing their work. "However, there are still many cases in which the negative aspects of speech become a barrier to peaceful resolution of conflicts, sometimes further harming society."
While the need for such an effective muting device is indisputable, the subtle fact remains that the SpeechJammer is anything but ... well, subtle. The latest version looks like a large mutant phaser from Star Trek, so chances are good that many chatterboxes will go silent the moment they see the thing pointed at them, regardless of whether it's turned on! Ultimately, it could also lead to more noise than it was initially trying to suppress (arguments and fisticuffs, anyone?) and there are sure to be freedom-of-speech issues to consider, as well.
Remember, should a workable form of the SpeechJammer ever come to market and you try to shut someone up with it, be on the safe side and make sure you're much bigger than they are!

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

By
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...

Nanogenerator that harnesses energy from tires friction

By
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...

New record energy efficiency for artificial photosynthesis

By
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...
