NanoLight claims to be world's most efficient light bulb

By - January 13, 2013 14 Pictures
Until recently LED light bulb manufacturers have struggled to find a solution in the 75 to 100-watt range which successfully replaces the soon-to-be redundant, energy crunching 100 W incandescent bulb in terms of size and brightness. Three friends from the University of Toronto are the latest to offer a feasible product to match the classic 100 W bulb without compromising on electricity consumption with their proposed NanoLight LED light bulbs.

Rolling HyTAQ robot avoids obstacles by taking to the air

By - November 28, 2012 4 Pictures
A team at the Robotics Lab at the Illinois Institute of Technology (IIT) has come up with another take on the caged flying robots like the spherical air vehicle developed by Japan’s Ministry of Defense (JMD) and the more recent Kyosho Space Ball. However, instead of a spherical shape, the the outer protective cage of the HyTAQ (Hybrid Terrestrial and Aerial Quadrotor) is cylindrical and is attached to the quadrotor via a shaft connected by two rotating joints, thereby providing the HyTAQ with the ability to fly or roll over the ground.

SEAD identifies the most energy-efficient TVs available

By - November 27, 2012
Size, resolution, the underlying display technology, 3D or not 3D, contrast ratio: these are all things one considers before splashing out on a television. How many of us think about energy consumption? The SEAD Initiative (Super-efficient Equipment and Appliance Deployment) is laboring under the apprehension that however many it is, it's not enough. What's it doing about? It's launching Global Efficiency Medal awards to very visibly identify the most energy-efficient flat-panel TVs (and other electronics), and last week it announced its winners ahead of an awards ceremony in January.

SOM's net zero New York school aims for "ultimate sustainability"

By - November 8, 2012 9 Pictures
Net zero: put together, they're two of the buzzwords of contemporary building design. Sometimes the phrasing's a little different. ZNE, or zero net energy, is one variation; zero-energy building is another. They're all the same thing, though: buildings designed to offset their energy consumption over the course of a year, every year. Work has commenced on one such project, a 444-student primary school on Staten Island, New York, designed by architects at SOM and engineers at AKF. Read More

Energy-saving Greencam app is a real turn-off

By - August 21, 2012
Computing guzzles a great deal of electricity and striving for greater energy efficiency both saves money and decreases greenhouse gas emissions. Although computers already come with energy-saving mechanisms, such as sleep mode and other power saving features set by users, there's always room for improvement. This is the idea behind Ecobeneficios’s Greencam. The Brazilian company has launched a PC app that automatically turns off the user’s monitor when he or she walks away from it. Read More

"Cool blue" pigment could boost energy efficient building

Researchers at Oregon State University have discovered a new type of blue pigment that could help boost the energy efficiency of buildings. Discovered unexpectedly three years ago, the "cool blue" pigment has unusually high infrared heat reflectivity which it is hoped can be channeled into commercial products in the near future.

Record setting small-scale solid oxide fuel cell could power neighborhoods

By - May 31, 2012 2 Pictures
A new, small-scale solid oxide fuel cell (SOFC) system developed at the Department of Energy’s Pacific Northwest National Laboratory (DoE PNNL) could be used for household and neighborhood power generation. Fueled by methane, the system achieves an efficiency of up to 57 percent, improving on the 30 to 50 percent efficiencies seen previously in SOFC systems of similar size. The PNNL researchers say the pilot system they have built generates enough electricity to power the average American home, and can be scaled up to provide power for 50 to 250 homes. Read More
