Over years, technology has a greater impact on the communication

between people. Each technology has allowed the faster sharing of

information, increasing the speed at which business can be conducted.

ientific method refers to

body of techniques for

vestigating phenomena,

quiring new knowledge,

correcting and integrat-

g p rev ious knowledge

Email is used to transfer mes-

sages in lightning fast, cheap,

simple, efficient, and versatileand environment friendly way

Now a days mobile phones became

a common accessory for everyone

which are provided with faster proces-

sors, vast storing capacity, advance

Operating Systems which can be used

In 1968, George Land gave 1,600 5-year-olds a creativity test used by NASA to select innovative engineers and scientists. He then re-

tested the same children at ages 10 and 15. The test results were staggering! 98% at age 5 registered genius level creativity, 30% at 10 year

and 12% at 15 years of age. The same test given to 280,000 adults placed their genius level creativity at only 2% !

Decline of Creativity

Finally George Land concluded that non-creative behaviour is learned. This indi-

cates that the creative genius in everyone is not gone. But it is suppressed. So if anyone

can unlearn, fail and relearn can make their creativity re-emerged. As one grows older

gaining more life experience, make more assumptions and finally take less creative risks.

Children are more inquisitive and ask more questions. Series questions are expres-

sion of their curiosity. Charles 'Chic' Thompson quotes “At home, parents utter eighteen

negative statements for every positive one--usually to an inquisitive child who wants to know

how something works”. The natural curiosity, which breeds creativity, is lost as they grow.

The parents, schools, colleges and later majority workplaces do not nurture this. As George

Land said, they learn the non-creative behaviour.

The paradigm shift is need of time in the society where questioning is encouraged. Itcan always lead to the better ways and change the way we perceive and live.

In a global information environment, the old pattern of education in answer-finding is one of no avail: one is

surrounded by answers, millions of them, moving and mutating at electric speed. Survival and control will depend on the ability to probe

and to question in the proper way and place.

-- M. McLuhan (probably written 30 or 40 years ago)

* Creativity begins with asking questions… * Innovation happens when you find answers…

* No questions, no answer * More questions, better answer

“The important thing is never to stop questioning.” - Albert Einstein



Introduction:

Natural daylighting is not a new concept, it can be seen in many historical buildings. With the advance of air conditioning rooms, day lighting

concept has been ignored and artificial lighting started influencing. As power demand growing day by day and , slowly daylighting technology

regaining its significance.

What is Day light ?

Day light is the combination of direct and indirect sunlight during

day time. The outdoor illuminance can vary from 120,000 lux for direct

sunlight at noon, to less than 5 lux during a storm clouds with the sun

at the horizon.

Significance of Daylighting :

1.Saves Energy thus reduces CO2 emissions. 2.Visual comfort

3.Connection to outside 4.Productivity 5.High Luminous Efficiency

30 years of engineering experience and a pioneer in the field of engineering and research.

Active Day lighting systems :

Active daylighting is a system of collecting sunlight using a mechanical device to increase the efficiency

of light collection for a given lighting purpose. They are of again two types

Open loop systems track the sun without physically following the sun via sensors These systems

typically employ electronic logic which controls device motors or actuators to follow the sun based on a

mathematical formula.

Closed loop systems track the sun by relying on a set of lenses or sensors with a limited field of view,

directed at the sun, and are fully illuminated by sunlight at all times. This article will focus on Light pipe

Technology which has lot of potential in Day lighting Technologies.

Light pipes :

Light pipes are primarily used for illuminating deep interior spaces where windows does not have provi-

sion for illuminating indoor environment. Light pipe consists of mainly three parts (collector ,

transmission pipe , diffuser).

Collector comprises of a Dome which has function of collecting sunlight from all angles and reflecting as

much as sunlight into the tube. Generally Polycarbonate or Acrylic Domes are used.

Light which is reflected in to the tube get multiple reflections and transport in to the tube. For every reflection

there will be some light loss , so our design should minimise these losses. Generally Anodized Aluminium with

Silver coating tubes are used. Silver has a high reflectivity of all materials known. Finally a Diffuser plate is placed

at the other end of the tube , whose function is to evenly distribute light inside the room.

Both direct and diffuse radiation falling on one end of the pipe can be channeled, after multiple reflections

off the inner walls, and used at the exit. The inner surface if mirror light pipes are made with a material having

high specular reflectivity for all angle of incidences and all wavelengths of considered spectrum width. Any

variation in spectral reflectivity of pipe surface leads to change in spectral distribution of transmitted radia-

tion. Lot of Mathematical models describe how the light get transmitted into pipe.

Science Corner :

Nikola Tesla (Serbian: 10 July 1856 – 7 January 1943) was an inventor, mechanical engineer, and electrical engineer. He

was an important contributor to the birth of commercial electricity, and is best known for his many revolutionary developments

in the field of electromagnetism in the late 19th and early 20th centuries. Tesla's patents and theoretical work formed the

basis of modern alternating current (AC) electric power systems, including the polyphase system of electrical distribution and

the AC motor. This work helped usher in the Second Industrial Revolution.

Tesla coi l:

A Tesla coil is a type of resonant transformer circuit invented by Nikola Tesla

around 1891.It is used to produce high voltage, low current, high frequency alter-

nating current electricity. Tesla coils produce higher current than the other source

of high voltage discharges, electrostatic machines. Tesla experimented with a num-

ber of different configurations and they consist of two, or sometimes three, coupled

resonant electric circuits. Tesla used these coils to conduct innovative experiments

in electrical lighting, phosphorescence, x-ray generation, high frequency alternat-

ing current phenomena, electrotherapy, and the transmission of electrical energy

without wires. Tesla coil circuits were used commercially in sparkgap radio trans-

mitters for wireless telegraphy until the 1920s,and in pseudomedical equipment

such as electrotherapy and violet ray devices. Today their main use is for enter-

tainment and educational displays.

Born 10 July 1856(1856-07-10)

Died 7 January 1943(1943-01-07)

Tesla demonstrated wireless energy transfer to power electronic devices as early as 1893, and aspired to intercontinen-

tal wireless transmission of industrial power in his unfinished Wardenclyffe Tower project. The SI unit measuring magnetic

field B (also referred to as the magnetic flux density and magnetic induction), the tesla, was named in his honor (at the

CGPM, Paris, 1960). Notable awards Edison Medal (1916), Elliott Cresson Medal (1893), John Scott Medal (1934)
