Following Gizmag's coverage of GE Lighting's 27 W Energy Smart
and Switch Lighting's 100 W-replacement
LED light bulbs, Osram Sylvania has been in touch to tell us about its 100 W-replacement LED light bulb, joining its Sylvania Ultra series: a 20 W, 1600 lumen light bulb with a warm, "incandescenty" color appearance of 2700 K. With Philips also to release a 100-W equivalent this means the big three manufacturers of light sources are joining Switch Lighting in offering high-output LED light bulbs for the home, but all things considered, Osram Sylvania's may prove the pick of the bunch.
GE Lighting has announced that it is getting in on the 100 W-equivalent LED replacement act. The 27 W Energy Smart LED bulb joins its range of incandescent bulb replacements that already includes 40 W and 60 W equivalents. And like an incandescent bulb, GE claims its LED bulb emits light evenly in all directions. But how does the 100 W equivalent stack up performance-wise?
A group of people including city planners and architects recently put a challenge to Dutch electronics company Philips: design an outdoor lighting system that helps to declutter our streets. The result was FreeStreet, a street lighting system that does away with vertical streetlight poles in favor of horizontally-strung cables that have clusters of LED lights built into them. The system won its designers a 2011 Dutch Design Award, and is available for use in Europe as of this month.
The soothing sound of canal water gently lapping against wood as you fall into peaceful slumber has got to be one of the best ways to end a relaxing day of leisurely cruising past sights that many Londoners rarely glimpse. Doing so on a vessel that gets the power for its motor, lighting and modern appliances from the Sun, features multi-layer insulation, underfloor heating and a charming wood-burning stove, and is surprisingly bright and roomy inside, seems too good to be true. Meet the Bauhaus Barge, a Dutch-style wide beam houseboat which is all of that and more.
The CHIP House - which stands for "Compact Hyper-Insulated Prototype" - was started with the goal of creating a net-zero energy home (i.e. one that requires no external energy source), and it looks like the designers exceeded that target. The house actually generates three times as much energy as it uses thanks to solar panels and a host of energy saving measures. The incredibly energy efficient design would make the house stand out on its own, but the integrated Kinect controls and smart features push the CHIP House above your typical green-conscious home and into "home of the future" material.
Hertford Regional College (HRC) in the UK has joined forces with the Thor Data Center (THORDC) in Iceland to provide cost efficient, eco-friendly technology to schools, colleges and universities throughout the UK. The joint venture has been coined "HRC Cube" and is an innovative solution to dealing with increasing cuts in UK government funding to education. Drawing on Iceland's combination of freezing temperatures and natural volcanic heat, THORDC has become one of the most energy-efficient data centers in the world. Powered by clean renewable hydroelectric and geothermal energy sources, the facility is claimed to offer cost savings to its customers whilst at the same time helping them lower their carbon emissions. The fact that it is situated in such a remote location also ensures a high level of security for the data.
LEDs last far longer than incandescent bulbs, are much more energy-efficient, and contain less toxic substances. Compact fluorescents give them a run for their money in some areas, although LEDs tend to have a warmer, “nicer” light. In the past few years, a number of companies have started marketing LED light fixtures that screw into traditional incandescent receptacles – these have included products from Geobulb
. A new arrival, however is the Bulled line of “bulbs” (for lack of a better word), from German manufacturer LEDO. If nothing else, they definitely have a look of their own.
UK-based chip manufacturer ARM has announced its most energy efficient CPU for portable electronics, called the Cortex A7, which will succeed the Cortex A8 CPU. The new arrival is designed to work as a stand-alone CPU in entry-level devices, and requires twenty percent the energy of its predecessor while offering twice the performance. High-end smartphones and tablets will also utilize the A7 as an additional source of computing power for less demanding tasks, with main processing provided by the upcoming ARM Cortex A15. Such a combination is dubbed big.LITTLE Processing.
On the last two occasions, the overall winner of the U.S. Department of Energy Solar Decathlon
has gone to Germany's Technische Universität Darmstadt but this year the top honor has stayed with one of the home teams. As the name might suggest, the University of Maryland's winning WaterShed
project features some novel innovations to make the best use of water, in addition to an intriguing internal waterfall that helps reduce the load on the structure's air conditioning system. Read on for a brief look at the top five winning projects, as well as the People's Choice.
As I look out of my office window and watch the heart-stopping acrobatics of feeding swifts, it's not difficult to see why so many aircraft designers find inspiration in nature - from birds
. Now it's the turn of the swift. Hoping to demonstrate the endurance and performance benefits of a combined flapping and gliding approach to Micro Air Vehicle (MAV) design, researchers have developed an experimental flyer capable of combining both unsteady and steady aerodynamics.
