BOSTON--Cynthia Loesch and Ivan Liriano built a green home as much for their community as themselves. The high-tech touches inside, though, were just for them.

The couple earlier this month hosted a ribbon cutting for the first LEED Platinum-level green building in Dorchester, the neighborhood in Boston where they both grew up. It's an example of how modern conveniences, such as home automation, fit nicely with green building gear.

When they took on the project to build in an abandoned lot, Loesch and Loriano were eager to build with energy-efficient appliances, good insulation, and solar panels. But the couple … Read more

Web giants and mega-size cloud-computing providers garner most of the attention when it comes to highly tuned and optimized data center designs. In April, Facebook shared the specifications for the servers it builds as part of an effort its calling the Open Compute Project. More recently, Facebook engineers have written about testing an extreme multi-core chip design from Tilera. Google has long been known for taking unique approaches to server and data center operations and design, although the company is generally secretive about the specifics.

This sort of hyper-optimization around scale was supposedly going to rapidly drive all computing to … Read more

OAKLAND, Calif.--It's fairly rare in 2010 to walk into a technology company where the first thing presented to visitors is a whiteboard covered in multicolor Post-It notes.

But that's exactly what lies just beyond the receptionist's desk at Ask.com, the venerable yet beleaguered Internet company in the middle of yet another strategy shift. The sticky notes are actually part of the company's product-development workflow, giving everyone a visual representation of the number of balls in the air at any given time, not just those logged into the project management software.

A solar-charged light might seem like just another green gadget to the average American, but for families in rural Africa, it could prove revolutionary.

Product design consultancy Plus Minus Design is vying to replace unsustainable and potentially dangerous lanterns in the homes of off-grid Africans with the Solar Pebble. Engineered with the economic constraints of developing-world citizens in mind, the Solar Pebble will provide one hour of LED light for every two hours of charge, and will cost only $2.70 to manufacture.

Plus Minus Design, based in Leeds, U.K., was founded by three undergraduate students at the University of Leeds. While studying product design and engineering, Adam Robinson, Henry James, and Tom Eales were given the opportunity to work with SolarAid, a charity in the U.K.

SolarAid, which works to fight poverty and climate change, worked with the students to develop a solar-powered alternative to kerosene lanterns. Those lanterns, commonly used in rural Africa, draw 20 percent of an average Malawian family's income, SolarAid said, and pose respiratory health problems, as well as create fire hazards. … Read more

Updated at 10 a.m. PDT October 20 with specific model of robotic arm used.

A robotic arm is lending a hand to children with dyspraxia, a motor-skills deficit also known as Developmental Coordination Disorder or Clumsy Child Syndrome.

The system, under development at the U.K.'s University of Leeds, combines a commercially available Phantom Omni haptic device with software that lets children with coordination problems practice therapist-prescribed exercises at home using an interactive desktop setup. It can also monitor how the kids move, measuring factors like smoothness, speed of movement, and joint configurations.

Guided by the robotic arm, for example, kids use a pen to push objects along a 3D track displayed on a computer screen. The system applies guiding forces to the child's arm and hand to help control movements. The strength of the forces can be altered to shape movements and vary the difficulty of the exercises.

"We originally started with a hospital-based system, but our user group of children said they'd much prefer to be able to use it at home after school, so we adapted it to a more suitable laptop-based system that fits inside a small holdall," said Mark Mon-Williams, a University of Leeds professor of cognitive psychology who is leading the research, in a statement. "They also got involved in the design of the games and exercises."

The Leeds team is collaborating with researchers at universities in Aberdeen, Scotland, and Indiana, with funding from U.K. children's health charity Action Medical Research.

Dyspraxia is a neurologically based disorder that affects the ability to see a movement goal through to completion. Children with dyspraxia struggle with skillful, controlled actions, making simple, daily tasks such as buttoning their coats more difficult. Handwriting often suffers, which can lead to homework struggles and ultimately a loss of self-confidence. … Read more

Engineers in England have come up with a product to save a few bob for those who work in semi-dangerous occupations--cement body armor.

The vests combine "super strong" cement with recycled carbon fiber, making the vests tough enough to withstand most bullet calibers, according to researchers at the University of Leeds' School of Civil Engineering.

Currently, top-of-the-line bulletproof vests are made with alumina plates--the raw material used to make aluminum--through a costly process called sintering, which involves heating the material for up to two weeks at 1600 degrees Celsius to harden it.

The cement vest, on the other hand, would offer a cost-effective level of protection for people in semi-risky occupations short of full-on combat.

"By using cement instead of alumina we are confident we can deliver a cost-effective level of protection for many people at risk," said research team leader Philip Purnell. "It should be good enough for people like security guards, reporters, and aid workers who are worried about the odd pot shot being taken at them." … Read more

CHICAGO--Fighting climate change requires making the nation's homes, offices, and schools healthier and more energy efficient, former president Bill Clinton told thousands attending the Greenbuild conference on Wednesday. Sweeping efforts to reduce the carbon footprints of buildings, which emit three-quarters of most cities' greenhouse gases, can measurably benefit the environment, he said.

"The sale's been made," Clinton said. "Otherwise Al Gore wouldn't have gotten the Nobel Prize. Now what we have to do is...to prove that this is not a big bottle of castor oil that we're being asked to drink."… Read more

Many of the nation's office and retail towers would use one-third less energy by 2012, if they meet goals set today by the Building Owners and Managers Association.

The group unveiled its plan at its annual conference in Manhattan to shrink the carbon emissions of some 9 billion square feet of commercial real estate, using the government's Energy Star benchmarks for energy and water usage. Green-building standards set by the nonprofit-run Leadership in Energy and Environmental Design are more stringent.

Still, this initiative, if successful, would significantly cut the $24 billion spent on energy each year by the … Read more
