The Holonic Streetlamp utilizes both solar and wind power

Streetlamps burn all night long, 365 nights a year, yet they also spend all day soaking up the Sun’s rays. This combination of regular usage alternating with sunlight exposure would seem to make them ideal candidates for the solar-power treatment. Indeed, companies such as Sharp and several others currently offer solar-powered streetlamps. Spain’s University of Seville, however, has developed a streetlamp that harnesses the power not only of sunlight, but also of wind.  Read More

Lights out!

The Bang! lamp, a "whimsical and interactive objet d'art" from Bitplay, is a novelty lamp that lets you shoot the lights on and off with a gun-shaped remote control. It's as useful as The Clapper, but much cooler and more fun.  Read More

A close-up view of the microlenses making up the biochip array

When we think of invisibility cloaks, probably the first things that come to mind are Harry Potter-like contraptions that allow people or large objects to instantly disappear. Scientists from the University of Maryland and nearby Towson University, however, today announced their development of something a little different – little being the key word. They have crammed 25,000 tiny “invisibility cloaks” onto a gold sheet, which itself only measures 25 millimeters per side. While the resulting biochip array may not allow any young wizards to vanish from sight, it could allow them to identify biological materials.  Read More

Little Sun can be hung, used as a table lamp, or taken out to be used as a lantern or bicy...

Icelandic artist Olafur Eliasson, whose body of work is mostly based on light installations, last week presented a small solar powered light during the World Economic Forum in Addis Ababa, Ethiopia. Olafur collaborated with engineer Frederik Ottesen to create Little Sun, which they hope can help bring indoor lighting to those people who lack access in developing countries.  Read More

SolarKindle is shipping its solar powered cover for Kindle Touch and Kindle 4

SolarFocus picked up the Innovation Award at CES 2012 for its SolarKindle e-Reader cover that features a built-in solar panel, integrated battery and LED reading lamp. The company has announced it is now shipping the device for both Kindle Touch and Kindle 4.  Read More

The Defender runs on three AA batteries, and incorporates watertight silicone gaskets

People who commute by bicycle don't have to remove their pedals, racks or fenders when they park in public ... so why should their lights be any different? Well, because most battery-operated bike lights come off with the simple flick of a quick-release, or the turning of a single bolt. Massachusetts-based Gotham Bicycle Defense Industries, however, is attempting to address that problem with its Defender bike light. Not only is it theft-resistant, but it's also waterproof, and it looks like the light Dirty Harry would use - if he rode a bike.  Read More

The NAO is Petzl's first headlamp to use Reactive Lighting

In addition to two powerful LED lights, the new NAO headlamp from Petzl has a light sensor. The headlamp doesn't just shine light, it measures ambient light to provide the ideal amount of output. It also uses a few other smart design features to give you a high-performing, convenient headlamp.  Read More

Virtual photons bounce off a 'mirror' that vibrates at almost the speed of light. The roun...

A perfect vacuum is impossible to achieve, at least in theory. As anyone with any interest in quantum physics would know, the vacuum is full of various particles that fluctuate in and out of existence. These "virtual" particles have been the focus of scientist, Christopher Wilson. Working with his team at Sweden's Chalmers University of Technology, Wilson has succeeded in producing real photons from these virtual photons. Which, in layman's terms, means that they have created measurable light ... from nothing.  Read More

The Philips bio-light is 'powered' by glowing bioluminescent bacteria

The search for greener, more power-efficient lighting systems won't stop with compact fluorescents and LED systems if Dutch electronics giant Philips has anything to say about it. In an effort to embrace a truly natural approach to lighting, the company took a cue from fireflies and deep-sea creatures to create a (literally) green light powered not by electricity or sunlight, but by glowing bioluminescent bacteria.  Read More

Scientists have discovered that objects coated with a forest of carbon nanotubes can be ma...

Although Klingon-style disappearing spaceships may not be in our neighborhood any time soon, the technology that could allow a spaceship to vanish from sight may be here now. Scientists from the University of Michigan have successfully made a three-dimensional etched silicon image of a tank appear as a featureless black void, that completely blended in with the backdrop surrounding it. The secret: good ol’ carbon nanotubes.  Read More
