Nanoparticles Make Steam without Bringing Water to a Boil

Nanoparticles Make Steam without Bringing Water to a Boil | TechWatch | Scoop.it

A new trick could reduce the energy needed for many industrial processes and make solar thermal energy much cheaper.

 

Steam is a key ingredient in a wide range of industrial and commercial processes—including electricity generation, water purification, alcohol distillation, and medical equipment sterilization.

 

Generating that steam, however, typically requires vast amounts of energy to heat and eventually boil water or another fluid. Now researchers at Rice University have found a shortcut. Using light-absorbing nanoparticles suspended in water, the group was able to turn the water molecules surrounding the nanoparticles into steam while scarcely raising the temperature of the remaining water. The trick could dramatically reduce the cost of many steam-reliant processes.

Password crackers go green by immersing their GPUs in mineral oil

Password crackers go green by immersing their GPUs in mineral oil | TechWatch | Scoop.it

Going where few password crackers have gone before, a team of security consultants has deployed a cracking-optimized computer that's completely submerged in mineral oil. Members say the setup offers significant cost savings compared with the same machine that uses air to stay cool.

 

The rig contains two AMD Radeon 6990 graphics cards, long considered a workhorse for password crackers. While the parallel processing in just one of these $800 cards can make as many as 9 billion password guesses each second (see PC3 in the graph at the bottom of this page), the performance comes at a price. GPUs run extremely hot, particularly when combined with other graphics cards, which drives up the cost of keeping them cool enough to run without burning out. The dedicated fans normally used to keep them cool also generate plenty of noise.

Forget Google Glass, Google Debuts ‘Talking Shoe’ Concept At SXSWi, Wants More Social, Motivational Everyday Objects

Forget Google Glass, Google Debuts ‘Talking Shoe’ Concept At SXSWi, Wants More Social, Motivational Everyday Objects | TechWatch | Scoop.it

Meet Google’s “talking shoe,” which aims to translate movement data in witty messages to users and their friends. The concept apparel, showcased at the search giant’s swanky SXSW Interactive headquarters, is part of a new arts project - ”Art, Copy, Code” – which aims to breathe a social, life-like experience into everyday objects. “If standing still was a sport, you’d be world champion,” the trash-talking shoe projects on a monitor hanging over a rainbow-colored obstacle course after it senses I’ve been standing still.

 

At a distance, users seem a tad pathetic trying to trigger positive feedback from the shoe. But when I strapped it on, I felt oddly compelled to impress my new automated coach. Combining coaching (even robotic coaching) made lifeless data unexpectedly motivational. Essentially, it’s Richards Simmons in a shoe.

Fujitsu Develops New Data Transfer Protocol Enabling Improved Transmissions Speeds

Fujitsu Develops New Data Transfer Protocol Enabling Improved Transmissions Speeds | TechWatch | Scoop.it

Fujitsu Laboratories Limited today announced the development of a new data transfer protocol that, by taking a software-only approach, can significantly improve the performance of file transfers, virtual desktops and other various communications applications.

 

Conventionally, when using transmission control protocol (TCP)(1)—the standard protocol employed in communications applications—in a low-quality communications environment, such as when connected to a wireless network or during times of line congestion, data loss (packet loss) can occur, leading to significant drops in transmission performance due to increased latency from having to retransmit data.

 

To address this problem, Fujitsu Laboratories has succeeded at a software-only approach, developing: 1) A new protocol that incorporates an efficient proprietarily developed retransmission method based on user datagram protocol (UDP)(2), an optimized way to deliver streaming media able to reduce latency resulting from data retransmission when packet loss occurs; 2) Control technology that addresses the problem of UDP transmissions consuming excess bandwidth by performing a real-time measurement of available network bandwidth and securing an optimal amount of communications bandwidth without overwhelming TCP's share of the bandwidth; and 3) Technology that, by employing the new protocol, makes it possible to easily speed up existing TCP applications without having to modify them.

Viewing 3D on a 2D Set

Viewing 3D on a 2D Set | TechWatch | Scoop.it

Ever wondered how you can watch 3D content on a 2D set? Dr Geoff Ogram explains ‘freeviewing’ and the difference between cross eye and parallel viewing.

 

Do you remember those Magic Eye pictures? By adjusting the way you looked at the specially encoded pictures, a 3D image would emerge. It is a way of seeinmg a 3D image on a regular 2D medium without having to wear glasses. When viewing 3D video on YouTube, one of the options is no-glasses where the viewer can switch between cross-eyed and parallel to see a 3D effect without glasses using the similar viewing method to Magic Eye.

BBC R&D White Paper : RE@CT - Immersive production and delivery of interactive 3D content

This paper describes the aims and concepts of the FP7 RE@CT project. Building upon the latest advances in 3D capture and free-viewpoint video RE@CT aims to revolutionise the production of realistic characters and significantly reduce costs by developing an automated process to extract and represent animated characters from actor performance capture in a multiple camera studio.

 

The key innovation is the development of methods for analysis and representation of 3D video to allow reuse for real-time interactive animation. This will enable efficient authoring of interactive characters with video quality appearance and motion.

 

This paper was presented at the NEM Summit, Istanbul, 16-18th October 2012.

The slides shown during the presentation are included as an appendix.

Drool-Worthy $99 Kit Lets Kids Build Their Own Computers

Drool-Worthy $99 Kit Lets Kids Build Their Own Computers | TechWatch | Scoop.it

Teaching children the basics of computer science isn’t as simple as teaching them to tie their shoes. How often do you see a parent sitting down with their kids, walking them through a line of code or pointing out the components of a motherboard? Probably never. Because kids think it’s boring. And parents think it’s hard. Today, children grow up surrounded by shiny objects that look and act like magic. There are screens that respond to touch and computers that can do just about anything a five-year-old can dream up. But even though kids have been immersed in technology since birth, it’s rare for them to actually know how it works.

New Closed-Captioning Glasses Help Deaf Go Out To The Movies

New Closed-Captioning Glasses Help Deaf Go Out To The Movies | TechWatch | Scoop.it

There will be a special attraction for deaf people in theaters nationwide soon. By the end of this month, Regal Cinemas plans to have distributed closed-captioning glasses to more than 6,000 theaters across the country.

 

Sony Entertainment Access Glasses are sort of like 3-D glasses, but for captioning. The captions are projected onto the glasses and appear to float about 10 feet in front of the user. They also come with audio tracks that describe the action on the screen for blind people, or they can boost the audio levels of the movie for those who are hard of hearing.

 

This is a big moment for the deaf, many of whom haven't been to the movies in a long time. Captioned screenings are few and far between, and current personal captioning devices that fit inside a cup holder with a screen attached are bulky, display the text out of their line of vision to the screen, and distract the other patrons.

IBM Creates a New Way to Make Faster and Smaller Transistors

IBM Creates a New Way to Make Faster and Smaller Transistors | TechWatch | Scoop.it

Researchers at IBM have assembled 10,000 carbon nanotube transistors on a silicon chip. With silicon transistors approaching fundamental limits to continued miniaturization, theIBM work points toward a possible new way of continuing to produce smaller, faster, more efficient computers.

 

Earlier work by IBM showed that nanotube transistors could run chips three times faster than silicon transistors while using only a third as much power. And at just two nanometers in diameter, the nanotubes—carbon molecules resembling rolled-up chicken wire—are so small that chip makers could theoretically cram far more transistors on a chip than is possible with silicon technology. But controlling the nanotubes’ placement in arrays numerous enough to be useful—ultimately, billions of transistors—is a major research challenge.

CES 2013: A Complete Tour of Ultra HD

CES 2013: A Complete Tour of Ultra HD | TechWatch | Scoop.it

CES 2013 is officially concluded. With over 150,000 people in attendance and almost 2 million square feet of exhibit space, the CEA has stated that it was their largest convention since its founding over 45 years ago.

 

I journeyed to Sin City to get an up-close look at the Ultra HD offerings from some of the biggest display manufacturers in the world, including Sharp, LG, Samsung, ViewSonic, Toshiba, Sony, Westinghouse, and Vizio. I will share my impressions of each in a few moments.

 

There appears to be plenty of cynicism regarding the future of Ultra High Definition technology. Many believe that price, lack of content, insufficient bandwidth, and enormous screen size will inevitably lead to its failure. While some of these limitations are apparent, one cannot simply dismiss the adoption of new technology because it sounds impossible or impractical. Technology is always evolving, and sometimes rapid changes in infrastructure allow for further adoption of new technology. Remember the incredible doubt when flat panel TV’s first debuted? These display companies know that their Ultra HD products are very expensive, and many of them intend to bring manufacturing costs down over the next few years. So why should we doubt progression? Ok, moving on to the summary…
