The perfect Remote, Programmable, Controller for interactive LED strips | O Since when white light emitting high brightness LED are available, the handover from traditional lighting bulbs to the solid-state lighting has become irreversible: LEDs have an efficiency (expressed in lumens/watt) higher than that of almost all the traditional lamps (except, at the moment, the large sodium vapor lamps used for street lighting, unusable in closed environments for the high power required and the chromatic aberration they produce) at a cost that is today less prohibitive than it was a few year ago. They are indeed very sturdy and have a very acceptable ratio of luminous flux and size. In common with the traditional lamps, at least with fluorescent and neon, white LEDs have the characteristic to be produced to emit, depending on the model, a shade of white that ranges from warm (3,000 K) to cold (over 6,000 K).

How to make a "perfect" solar absorber The key to creating a material that would be ideal for converting solar energy to heat is tuning the material's spectrum of absorption just right: It should absorb virtually all wavelengths of light that reach Earth's surface from the sun—but not much of the rest of the spectrum, since that would increase the energy that is reradiated by the material, and thus lost to the conversion process. Now researchers at MIT say they have accomplished the development of a material that comes very close to the "ideal" for solar absorption. The material is a two-dimensional metallic dielectric photonic crystal, and has the additional benefits of absorbing sunlight from a wide range of angles and withstanding extremely high temperatures. Perhaps most importantly, the material can also be made cheaply at large scales. Most of the sun's energy reaches us within a specific band of wavelengths, Chou explains, ranging from the ultraviolet through visible light and into the near-infrared.

Volcanic lightning storms are creating perfect crystal balls - ScienceAlert Scientists have discovered tiny, perfectly round spheres of glass in the ash left over from volcanic explosions, and say they could be the key to understanding how and why lightning forms in these crazy-volatile events. The team, led by volcanologist Kimberly Genareau from the University of Alabama in the US, examined the ash from two massive eruptions - the 2009 Mount Redoubt eruption in Alaska, and the 2010 Eyjafjallajökull eruption in Iceland - to find glass balls measuring just 50 microns across (a micron equals 0.001 millimetres). Researchers have known for years that volcanic eruptions produce tiny, jagged fragments of glass, but the consistent shape and smooth surface of these spheres came as something of a surprise. This lightning could be the key to creating the spheres, says Becky Oskin at Live Science, because they heat the air within the ash clouds to temperatures of around 30,000 degrees Celsius (54,000 degrees Fahrenheit), within mere millionths of a second.
