Conclusion

A global system for "the transmission

of electrical energy without wires"

called the World Wireless System.

It was proposed as early as 1904.

Since wireless electricity is not yet a reality. It is a new groundbreaking

technology.

In 1899, Serbian engineer Nikola Tesla built a 142-foot-tall, 12-

million-volt electric coil in Colorado and transmitted electricity

wirelessly across 25 miles, illuminating 200 lamps with the charge.

70 years before Tesla, Michael Faraday discovered electromagnetic

induction (like in transformers).

HISTORY

Imagine a future in which wireless electricity makes

everyday products more convenient, reliable, and

environmental friendly

Charge Your Phone (and Your Car) from AfarCharging systems that send power farther through the

air will soon be on sale.

INTRODUCTION Wireless Charging:

Smart phones are changing the way we live our lives. With each new

model, we are getting high processing speed, new features and

programs and new ways for using them.

Despite of increased capabilities, battery life simply has not kept up. We

want to eliminate the problem of the dead battery

Wireless charging is already available for low-power applications

(up to 5 Watts), suitable for mobile phones and other devices. However,

medium- and high-power applications are also being developed in the

future .

Snack charging on-the-go

Imagine that you are doing some work, and

you have placed your mobile on the table.

The mobile lights up, and starts chargingautomatically– without connectors or cables.

It would be even better if you did not need

a charger ever.

The technology behind wireless charging

The technology and theory behind wireless charging

was initially suggested by Nikola Tesla.

“The technology requires two coils:

1. a transmitter

2. a receiver.

An alternating current is passed through the transmitter

coil, which generates a magnetic field. This in turn induces

a voltage in the receiver coil. This can be used to power a

mobile or a device ”

Most electric tooth brushes recharge through inductive coupling

WiTricity technology transfer’s electrical energy over

distance without wires .

CEO Eric Giler’s dream is to combine the best of both

world’s, power and distance. Not only is Witricity working to

power mobile devices, laptops, and TV’s. But Witricity also

has plans to wirelessly charge electric cars.

Wi-Tricity Technology:

Witricity focuses on the powering of devices such as phones and

TV’s, microwave transmissions .

Power mat (wireless charger whose range is limited to few cm’s),

Power Beam, UBeam, are applications.

Broadcasting electricity for hundreds of miles is just one

application of wireless electricity.

The challenges that wired technologies are facing due to

inefficiencies and lack of control, safety and other issues. To over come

this we require wireless energy transfer.

As this technology reaches its tip point and realizes mass adoption

with consumers, it is very important for engineers and design teams,

manufacturers and governing bodies cooperate with each other for

developments. Also future consumer needs is always made the first

priority.

Only by doing so universal power delivery will reach its potential

and make world truly wireless.
