Light tube
Light tubes Light tubes or light pipes are used for transporting or distributing natural or artificial light. In their application to daylighting , they are also often called tubular daylighting devices, sun pipes , sun scopes , or daylight pipes . Generally speaking, a light pipe or light tube may refer to: a tube or pipe for transport of light to another location, minimizing the loss of light; a transparent tube or pipe for distribution of light over its length, either for equidistribution along the entire length (see also sulfur lamp ) or for controlled light leakage. Both have the purpose of lighting, for example in architecture .
LIGHTING---APPLIANCES
Increased Energy Saving You’ve probably heard the statistic of how dimming a light 15% in electricity usage and extends the life of your light bulbs. Why stop there?Himawari Sunlight collection at maximum efficiency with a system-lens focusing and optical fiber transmission The Himawari system consists of a lens focusing unit and optical fiber devices. Its outdoor collector can collect sunlight always at maximum efficiency and transmit it through optical fibers to anywhere you want. Unlike conventional

LiTraCon is a trademark for a translucent concrete building material. The name is short for "light-transmitting concrete". The technical data sheet from the manufacturer [ 1 ] says the material is made of 96% concrete and 4% by weight of optical fibers , [ 2 ] [ 3 ] it was developed in 2001 by Hungarian architect Áron Losonczi working with scientists at the Technical University of Budapest . [ 4 ] LiTraCon is manufactured by the inventor's company, LiTraCon Bt, which was founded in spring 2004. The head office and workshop is near the town of Csongrád .

Daylighting
A skylight providing internal illumination Daylighting is the practice of placing windows or other openings and reflective surfaces so that during the day natural light provides effective internal lighting . Particular attention is given to daylighting while designing a building when the aim is to maximize visual comfort or to reduce energy use. Energy savings can be achieved either from the reduced use of artificial (electric) lighting or from passive solar heating or cooling.
Cool Light on Hot Days: Fiber Optics Bring the Sun Indoors
Piping in sunlight without using electricity is a win-win proposition for the ecosystem and human society. Both home and business customers anticipate energy savings and a more pleasant indoor environment. by Mary-Sue Haliburton Pure Energy Systems News Copyright © 2005
How cloud computing changes IT staff
A good friend who spent years selling to CIOs once commented about CIO priorities "They can only focus on three big things, and two of them are budgets and people, so don't expect that it's easy making your widget a top priority within the organisation." There's a lot of wisdom in my friend's perspectives, and it's instructive to think about what the people side of cloud computing is going to look like or to put it another way, how will cloud computing change the various roles within an IT organisation and how will it change their importance, relative to one another? We believe it's impossible to understand these questions without understanding the environment in which IT personnel will be working in the cloud computing future. Our prediction is scale: big data, more (virtual) servers, more applications, much larger applications, and many more highly elastic applications. In the past, growth in computing capacity was mirrored by a linear growth in headcount.
Could a mixture of water and clay replace plastics? The desire to wean the world off oil has sparked all manner of research into novel transportation fuels, but manufacturing plastics uses large amounts of oil too. Researchers at the University of Tokyo, Japan, think their material could be up to the task. Takuzo Aida and his team mixed a few grams of clay with 100 grams of water in the presence of tiny quantities of a thickening agent called sodium polyacrylate and an organic "molecular glue". The thickening agent teases apart the clay into thin sheets, increasing its surface area and allowing the glue to get a better hold on it.

On the afternoon of 22 January 1907, a wailing chorus of steamboat whistles sent the residents of Memphis, Tennessee, running to the banks of the Mississippi river. "A great crowd assembled on the riverside, thinking some great disaster was taking place on the water," reported the Memphis News-Scimitar. Instead, the swelling crowd was greeted by the sight of a man calmly walking on water. This was no miracle.
