4. AGENDA
Introduction
HISTORY
WORKNG PRINCIPLE
How it works
Sources and applications
Advantages and Disadvantages

5. INTRODUCTION
Radiant energy:
The energy of electromagnetic and gravitational radiation
 As energy, its SI unit is the joule (J)
 When electromagnetic radiation is emitted by a source into
the surrounding environment. This radiation may be visible
or invisible to the human eye.
 The quantity of radiant energy may be calculated
by integrating radiant flux (or power) with respect to time

6.  The symbol Qe is often used throughout literature to denote radiant energy ("e"
for "energetic", to avoid confusion with photometric quantities).
 It is a form of energy that can travel through space. For example, we receive the
heat from the sun

7. HISTORY
 In 1875, Sir William Crookes discovered the
properties of Radiant Matter.
 According to invention of Radiometer the Radiant
Matter was a constituent of sunlight.
 Nikola Tesla,found that electrostatic charges could
also be conveyed by Radiant Matter. He called it
Radiant Energy.
 Tesla found that Energy was transmitted from place
to place, it behaved like “sound waves of electrified
air”
 By 1900, Tesla had developed lighting systems and
electric motors that ran on Radiant Energy.
 By 1934, Thomas Henry Moray had demonstrated a
small box that produced 50,000 watts, running on
Radiant Energy

8. • By 1934, Thomas Henry Moray had demonstrated a small box that produced 50,000
watts, running on Radiant Energy
• And Paul Baumann built numerous models of an astonishing self-running machine
called “Testatika” in Switzerland in the 1980’s.
• Furthermore contineusly researches are take place at radian energy and also known
as power of future

9. IMPORTANCE OF RADIANT
ENERGY IN YOUR DAILY LIFE
 Now these days radiant energy is an important part of life
 Well today, our radio airways are related with derivations of Tesla’s inventions
Satellites, Cell phones, gpS systems
 air craft navigation and even garage door openers, all require that unwanted
radio waves
 the Sun or sunlight is our primary source of radiant energy without it life on
Earth would pretty much cease to exist.
 Radiant energy is given off by space heaters, toasters, stove burners, light bulbs
(give radiant energy as heat and as light, etc..
 All electromagnetic energy from gamma rays, x-rays, thru radio waves are types
of radiant energy.

10. WORKING PRINCIPLE
According to stephan-boltzman law
The amount of heat which is radiated (e) by a perfect black body for a second in a given unit
area is directly proportional to the fourth power of its absolute temperature (t).

11. HOW TO WORK RADIANT
ENERGY
 In working Tesla’s plan was ingeniously simple,
and actually works
 You just need a Tower that you can resonated
 an oscillator of moderate power,
 Some tuning equipment, and
 a little tweaking

12. SENDING OF SIGNALS
 Now you are all set, to send out your excitation signal
ON THE RECEIVING END ALL YOU
NEED IS
• An appropriately wound and tuned resonant circuit,
• A ground rod of good 6uality, and
• One wire going to your light bulb
• So in this way you will get radiant energy

13. SOURCES OF RADIANT
ENERGY
Virtually anything that has a temperature gives off radiant energy. Some examples of radiant
energy include:
 surface heated by the sun converts into radiant energy
 X-rays give off radiant energy
 Microwaves utilize radiant energy
 Space heaters produce radiant energy
 The heat from a grill used for cooking
 Heat created by the body can be radiant energy
 Visible light
 Gamma rays
 Radio waves
 Electricity
 Ultraviolet light… etc

14. APPLICATIONS OF RADIANT
ENERGY
As radiant energy is used in many application as
 The branch of medical science that deals with diagnosis and treatment of diseases with
the help of different types of radiant energy is known as Radiology
 Radiant energy is used to heat things up (an oven or a baseboard heating system)
 Radiant energy is used to produce light in many application like a light bulb or laser
pointer etc..
 Radiant energy is used to carry information from one place to another as a radio
broadcast or cell phone.

15. Advantages and Dis-advantages
Advantages of Radiant energy
 Radiant energy systems is relatively cheap to set up,
 That energy system need just an antenna, some wires and basic capacitors.
 it is easy to use radiant energy on a small scale.
 Such systems already exist in water heating devices which make direct use the
Sun’s rays and even photographic development equipment.
 That system can qucikly installed
 Radiant energy system can easily expand or upgrade
 Don’t have pollution factors like CO2 emission

16. Disadvantages of Radiant energy:
 Radiant energy is not useful in terms of producing large amounts of energy.
 Radiant energy system required high amount of sun or sun light
 That system required electrical system to storage and backup of radiant energy
 That radiant energy system has low efficiency
 Large space is required for setup
