Title: Use Me !


1
The Energy Which Never Ends !
Use Me !
2
Energy Crisis is the one of the major issues
which influence our lifestyle. Its not pertaining
to a particular state or nation, its a global
issue influencing whole world. Working for a
pollution free environment and promoting
renewable energies is the responsibility of all.
3
Why Solar Energy ?
  • It is a readily available source of energy.
  • It does not belong to anybody and is, therefore,
    free.
  • It is non-polluting and therefore, helps in
    lessening the greenhouse effect.

4
  • India receives solar energy equivalent to over
    5000 trillion kWh/year, which is far more than
    the total energy consumption of the country.
    Using solar energy effectively will solve our
    countrys energy problems.

5
How can I use solar energy effectively?
6
We are..
Committee members of Karnataka Energy Development
Agency.
7
Our Goal
  • Conduct research and design a solar cooker which
    is energy efficient.

How can we best design a solar cooker?
8
Area of Study
  • Solar Cooker Material Research
  • Solar Cooker Design Research

9
What we did
We studied basic principles and three models to
develop an improved solar cooker. Each design has
its own advantages and disadvantages. So by
considering these three as base we came out with
improved design of our vision.
10
Box Cooker
A solar box cooker is an insulated box with a
transparent top and a reflective lid.
Advantages
Disadvantages
  • Simple and easy to make
  • Cost is less
  • Cant utilize more energy.
  • Heat loss is there

11
Panel Cooker
Solar panel cookers have multiple simple
reflectors arranged to focus solar radiation onto
a covered black pot enclosed in a clear
heat-resistant plastic bag or other clear
enclosure
Advantages
Disadvantages
  • Most of the energy is utilized with more
    reflectors.
  • Simple and easy to make
  • Heat loss is there
  • Heat storage less

12
Parabolic Cookers
Parabolic solar cookers have parabolic reflector
arranged to focus solar radiation onto a cooker
or food box
Advantages
Disadvantages
  • Good energy utilization and focusing
  • Less heat storage area
  • Heat loss

13
Factors Considered
  • Good Materials
  • Attractive Design easy to use
  • Maximum utilization of energy
  • Minimize heat loss
  • More heat storage

14
Our Design
15
How it is Different ?
  • Glass orientation is very good in such a way that
    it faces the sun directly and increases heat
    gain.
  • Reflectors were used on the top of the box to
    bounce/ focus additional sun light through the
    glass and into solar box results in higher cooker
    temperatures.
  • To prevent loss of heat via conduction through
    the bottom of the cooker, the absorber plate is
    raised from the bottom using small insulating
    spacers.
  • Structural and insulating material was used so
    that the box will have and retain a given shape
    and form, and be durable over time
  • Its incorporated all the essential qualities of
    Box, Panel and Parabolic Cookers.

16
Special Attraction !!!
  • Good Heat Gain
  • Less Heat Loss
  • More Heat Storage
  • Structured Insulated Material
  • Moisture Barrier
  • Long Durability
  • Less Maintenance
  • Easy to Use
