SmartLight redirects sunlight into "light-locked" building interiors

Researchers at the University of Cincinnati have developed technology that could help cut lighting energy costs by brightening up rooms with natural light. The SmartLight system is designed to direct sunlight into dark, dingy rooms located within the bowels of buildings without requiring the installation of new wiring, ducts, tubes or cables. It also allows excess light to be harnessed and centrally stored to provide energy for electric lighting on cloudy days. Read More

Would you like to work in an all-glass office?

The ubiquitous office cubicle has redefined how much privacy pencil-pushers can expect during their daily grind, but a new office block in downtown Shanghai by AIM Architecture goes much further than this. The futuristic-looking workplace sports glass walls and mirrored ceilings throughout to stunning effect. Read More

Numerouno: A sleek hanging lamp made from cardboard

German designer Johannes Kiessler has created a sleek hanging lamp which is predominantly made from cardboard. Dubbed, Numerouno, the eco-friendly lamp weighs a mere 600 g (21 oz) and features a low consumption 21 W fluorescent tube that emits the same amount of light as a traditional 150 W light bulb.

Starpath spray-on coating lights up the road

UK company Pro-Teq has developed a new water-resistant, spray-on coating that absorbs UV light during the day and releases it at night, adapting to the lighting conditions in its surroundings. The technology is being given a test run at the Christ's Pieces park in Cambridge, and could prove a cost effective alternative to conventional street lighting.Read More

Spirit Solar Powered Lighting Column integrates panels into the post

Street lights are one of things people in heavily populated areas tend to take for granted. They make walking and driving a safer, more pleasant experience, but they also account for a significant chunk of a city's energy usage. Solar powered street lights offer a solution for places where electricity is at a premium, or locations that are off the grid completely and the Spirit Solar Powered Lighting Column is the first example we've seen which rolls the post and the panels together in a standalone design.Read More

Wired merry-go-rounds provide energy to remote schools in Ghana

At first glance, a merry-go-round that generates electricity appears to be a charming idea. But Empower Playgrounds President, Ben Markham, came up with the idea in 2006 during an 18-month stint volunteering in Ghana. There he was struck by the lack of lighting in rural schools and dwellings, as well as the paucity of playground equipment. A charming idea it remains, but it's a serious one, too.Read More

USS Enterprise-like flat LED light bulb could end up selling for $3

Not long ago, we took a look at Cree’s new LED light bulbs. At US$12.97 a pop, the 60-watt-equivalent model sounded like a pretty good deal. If NliteN’s disk-shaped 2D-Lite reaches production, however, it could make the Cree product look downright expensive. Initially slated to sell for $10, the dimmable 60-watt-equivalent "800 lumen-class" bulb is planned to drop to $6 by 2015, and to $3 by 2017. Read More

Smart Glass controls both lighting and heat levels

Researchers at the Lawrence Berkeley National Laboratory have produced a "smart" glass coating that can be selectively controlled to block visible light, heat-producing near-infrared (NIR) light, or both, by applying a small electrical charge to it. The ability to do this dynamically has the potential to deliver improved lighting, heating, and cooling efficiency in buildings, thereby maximizing energy savings and still providing bright and well lit environments in different weather conditions.Read More
