Experiment no. 26 Alterations and variations
This last experiment is not one, but many experiments. In all depends on how
interested you are in learning more about solar energy.
You could make two more solar traps: one ? the size described here, the other twice
the size.
Similarly, you could make a larger and smaller
solar reflector (Chinese hat) and compare them.
Of course, the larger the reflecting surface, the
more energy can be collected and concentrated.
However, it is not only the amount of surface area
that matters. What would happen if you changed
the angle of the solar trap? You could change
the angle of the solar trap as illustrated in A or
as in B.
At what point within the cone is the heat as its greatest?
What would happen if you overlapped the lips of your slit in the solar collector more
than 3 cm or less?
CONCLUSION
You have now hopefully completed the experiments with solar energy that are in this
booklet. Solar energy is an endless energy source available in our world today.
n order to answer the needs of the future, new technologies need to be developed.
Worldwide research is underway and is constantly progressing in the field.
The development of alternative energy sources is essential.
Our goal is to introduce you to the basics of solar energy.
We hope that by performing the experiments in this kit, you have become familiar
and aware of the powers and effects of solar energy.
