self charging laptops

2.  While using laptop more heat is generated at
the bottom.
 Due to this waste heat,many are suffering
with health problems.
so,why don’t we create a device which
absorbs the heat and use this heat as charging
to the laptop itself.

3. • A thermocouple is a device that can convert thermal
energy into electrical energy.
• It consists of two different metals (bimetal) joined
together that conduct heat at slightly different rates.
•When heated, the difference in conduction results in
electricity flowing from one metal to the other.

6. • A thermocouple can produce current to drive some
processes directly, without the need for extra
circuitry and power sources.
• Commercial thermocouples are inexpensive,
interchangeable, and can measure a wide range of
temperatures.
•Thermocouples are self powered and require no
external form of excitation.

7.  One of the wire in the junction is kept where
heat is generated and other at room
temperature.
 So,the temperature difference creates emf-
thermo electric action.

8. •The main limitation with
thermocouples
is accuracy.
•Aging of thermocouples

9.  Since the energy available from a single
thermocouple is very small, arrays of thermocouples
must be used.
 Higher power devices can be made by connecting
thermocouples in series to increase the voltage
capability and in parallel to increase the current
capacity.
 Such an array of thermocouples is called a
thermopile.

10. In this competitive world , every one
uses laptop.
As our product does not generate heat ,
it is helpful.
As it is a self charging , it saves
electricity.

11.  Many people uses laptops,so this product will
give profitious result.
 This technique is of less cost.
 And,also occupies less space.Thermocouples are
small, convenient, flexible, cover wide ranges,
reasonably stable, reproducible, accurate, fast.

12.  A company has created a chip which converts
heat into electricity by using some alloy.
 It said that , it is going to make deal with Dell
andApple companies.
 So , may be in future Dell and Apple may
coming up with this technology.

13. We are providing some extra features such as,
Additional components like a battery can
also be added in the circuitry, in order to
store the energy and reuse it whenever
required.
 Fast installation through professional
planning and execution
 As we are using amplifiers and rectifiers , we
will get high supply and constant voltage.
 We can also use this heat as supply to other
electronic devices also.

14.  Low capital expenditures due to standard
components.
 High profits are guaranteed due to
minimum maintenance costs.
 Lower operation costs through own power
generation.
