The concept of using to CTRIC RGY
can betaken from ICROPHONE.
ICROPHONE is an acoustic-to-electric transducer or
sensor that converts sound into an electrical signal .
The sensitivetransducer element of a microphone iscalled its element or capsule. complete microphone also
includes a housing, some means of bringing the signal
from theelementto other equipment, and often an
electronic circuitto adaptthe output ofthe capsuleto the
equipment being driven. icrophones are referred to bytheir transducer principle, such as condenser, dynamic,
etc.

A transducer is an electronic device that convertsenergy from one form to another. Common examplesinclude microphones, loudspeakers, thermometers,position and pressure sensors
Efficiency is an important consideration in anytransducer. Transducer efficiency is defined as theratio of the power output in the desired form to thetotal power input. Mathematically, if Prepresents thetotal power input and Qrepresents the power outputin the desired form, then the efficiency E, as a ratiobetween 0 and 1, is given by:
E= Q/P
If E% represents the efficiency as a percentage, then:
E% = 100Q/P

1. Sound waves carry energy toward the
microphone.
2. The diaphragm moves back and forth
when sound waves hit it.
3. The coil, attached to the diaphragm,
moves back and forth as well.
4. The permanent magnet produces a
magnetic field that cuts through the coil.
As the coil moves back and forth throughthe magnetic field, an electric currentflows through it.
5. The electric current flows out from the
microphone to an amplifier or sound
recording device.

The change of thermal energy can be used to
generate electricity possible by the principle
of SEEBACK-EFFECT.

SEEBACKEFFECT there will be conduction ofelectron due to temperature difference so
this effect can also can be used to recharge
the mobile battery.Citizen Eco-Drive Thermo watches were
introduced in 1999 and use the temperature
difference between the wearer's arm and the
surrounding environment as a power source.

The pulse energy Ep is simply the total
optical energy content of a pulse. For single
pulses, e.g. from a Q-switched laser, the
pulse energy may be measured.Our HEART generates pulse energy so this
pulse can be used as a source of energy.

Today we are facing a lot of problem due to
scarcity of power.
July 10 (Reuters) - India's peak power
deficit is expected to widen in the currentfiscal year to 12.6 percent from 11.9percent in the 2008/09 fiscal year thatended in March, junior power minister
Bharatsingh Solanki said

Nowrdays mobile has become a basic need
for the human beings because it has
produced a revolution in communication
field. But due to busy time schedule a person get
less time to recharge or some time leave
mobile idle during the charging.
So to solve these problems we can use thisabove discussed technology.
