wireless power transmission, wireless energy transmission, or electromagnetic power transfer is the transmission of electrical energy without wires.
Wireless power techniques mainly fall into two categories, non-radiative and radiative.
In near field or non-radiative techniques, power is transferred by magnetic fields using inductive coupling between coils of wire, or by electric fields using capacitive coupling between metal electrodes.
In far-field or radiative techniques, also called power beaming, power is transferred by beams of electromagnetic radiation, like microwaves or laser beams.

The idea of wireless electricity has been around since the early days of the Tesla coil.
Earthing, also known as grounding, is based on research that demonstrate that connecting to Earth's electrical energy promotes physical wellbeing. The act of Earthing refers to a physical connection between the electrical frequencies of the human body with that of Earth's (think barefoot in the grass, or at the beach).

WiTricity technology is a non-radiative mode of energy transfer, relying on the magnetic near field. Magnetic fields interact very weakly with biological organisms—people and animals—and are scientifically regarded to be safe.
Wireless power transmission has become the new era in modern technology.The usage of this system is increasing day by day.This slide contains basic elementary topics about wireless power transmission.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

3. INTRODUCTION (OR DEFINITION)
wireless power transmission, wireless energy
transmission, or electromagnetic power transfer is the
transmission of electrical energy without wires.
Wireless power techniques mainly fall into two
categories, non-radiative and radiative.
In near field or non-radiative techniques, power is
transferred by magnetic fields using inductive
coupling between coils of wire, or by electric
fields using capacitive coupling between
metal electrodes.
In far-field or radiative techniques, also called power
beaming, power is transferred by beams
of electromagnetic radiation,
like microwaves or laser beams.
4. HISTORY
Nikola Tesla (1856 - 1943)
“Nikola Tesla, the eccentric - and unbelievably under-rated - genius known as
the ‘wild man of electronics’, was without doubt one of the greatest minds in
the history of the human race.”The first one who gave the idea of wireless
electricity.
MIT Scientists (in 2007)
• The idea of wireless electricity has been around since the
early days of the Tesla coil.
• But a group of MIT scientists, "WiTricity" (as these scientists
call it) is now one step closer to practical reality.
• Demonstrating the ability to power a 60-watt light bulb from a
power source seven feet away without wires might not seem like
the most impressive of feats.
5. HOW IT WORKS?
1. Magnetic coil (Antenna A) is housed in a box and
can be set in wall or ceiling.
2. Antenna A, powered by mains, resonates at a
specific frequency.
3. Electromagnetic waves transmitted through the air.
4. Second magnetic coil (Antenna B) fitted in
laptop/TV etc resonates at same frequency as first
coil and absorbs energy.
5. Energy charges the device.
6. USES
Wireless electricity can be used to power recharge and its
uses are as follows:
Cell Phones.
TVs.
Computers.
Electric Cars.
Cordless Tools.
Industrial Machinery.
Medical Devices (pacemakers, etc.).
Military Devices (unmanned robots, planes).
Consumer Appliance.
ANYTHING ELECTRIC!
7. PROS & CONS
PROS
• Significant decluttering of
office space
• No need for meter rooms
and electrical closets.
• Reduction of e-waste by
eliminating the need for
power cords
• Need more light in your
office, no need for
electrician. Simply place the
lamp where ever you need it.
CONS
• Need for standardization and
adaptation. So no
overheating occurs because
of different voltages.
• Retrofitting old equipment
or purchasing new
equipment could become a
very expensive endeavor
• possibility of “energy theft”.
Wi Fi, someone can be using
your internet or your power.
8. WHY DO WE NEED IT?
We need wireless electricity because of:
Safety.
Durability.
Aesthetics.
Clutter.
Efficiency.
9. COST
Cost is still undetermined.
What they say is there are no exotic
materials being used that would make it
overly expensive.
Prices should be comparable to products
already out.
10. CONCLUSION
Wireless power transfer is quickly becoming a viable
reality.
This technology offers an extremely efficient
alternative to previous attempts at providing
wireless power transfer.
Future improvements in wireless technology offer
world changing implications.
