Natural infrared. Sunlight, at an effective temperature of 5,780 kelvins (5,510 °C, 9,940 °F), is composed of near-thermal-spectrum radiation that is slightly more than half infrared. At zenith, sunlight provides an irradiance of just over 1 kilowatt per square meter at sea level. Of this energy, 527 watts is infrared radiation, 445 watts is visible light, and 32 watts is ultraviolet …

Sunlight has two components, the "direct beam" that carries about 90% of the solar energy, and the "diffuse sunlight" that carries the remainder – the diffuse portion is the blue sky on a clear day, and is a larger proportion of the total on cloudy days. As the majority of the energy is in the direct beam, maximizing collection requires the Sun to be visible to the panels for as long as ...

E Ink is made into a film and then integrated into electronic displays, enabling novel applications in phones, watches, magazines, wearables and e-readers, etc. The Motorola F3 was the first mobile phone to employ E Ink technology in its display to take advantage of the material's ultra-low power consumption. In addition, the Samsung Alias 2 uses this technology in its keypad in …

Twice a year, in mid-November and in late January, the corridor lines up lengthwise with the position of the Sun, causing sunlight to fill the entire corridor.

Chlorine dioxide is a chemical compound with the formula ClO 2 that exists as yellowish-green gas above 11 °C, a reddish-brown liquid between 11 °C and −59 °C, and as bright orange crystals below −59 °C. It is usually handled as an aqueous solution. It is also commonly used as a bleach.More recent developments have extended its applications in food processing and as a …
