2> SPHERICAL SUN POWER GENERATOR
3> WORKING PRINCIPLE
4> APPLICATIONS
5> MERITS
6> DEMERITS
7> CONCLUSION

3. 1> As we all know that Sun is an abundant source of
energy for planet Earth i.e. solar energy.
2> Solar Energy is the radiant light and heat from Sun
which is harnessed by several methods for generation
of power.
3> Solar Energy is available in plenty and several
techniques are being developed everyday to convert
that solar energy into other forms of energy such as
electrical energy, thermal energy etc.
4> Solar Cells or Photovoltaic Cells( PV ) are being
used extensively to convert solar energy to electrical
energy.
5> But Solar Cells are less efficient and fails to harness
sufficient power from Sun as the Sun’s inclination
changes throughout the day.
6> German Architect Andre Broessel believes he has a
solution that can “squeeze more juice out of the sun”,
even during the night hours and in low-light regions.

4. 1>His company Rawlemon has created a
spherical sun power generator prototype
called the beta.ray.
2> His technology will combine spherical
geometry principles with a dual axis tracking
system, allowing twice the yield of
a conventional solar panel in a much smaller
surface area.
3> The futuristic design is fully rotational and
is suitable for inclined surfaces, walls of
buildings, and anywhere with access to the
sky.

5. 1> By using the perfect geometry of
ball lens, we could concentrate the light
at focal point.
2> It will make it more sustainable
because the cell surface is reduced.
3> It will make it more efficient
because it will generate more energy
and even at diffused light.
4> Miniaturization makes possible, the
use of micro tracking system that traces
the path of Sun throughout the day as
well as that of moon throughout the
night.

6. 1> It can be used as an electric car
charging station.
2> Electricity can be generated from
PV cells and can be fed to our homes
and offices.
3> Thermal energy so obtained can
be used as solar heating i.e. heating
water using solar thermal collector.
4> At night time the Ball Lens can
transform into a high-power lamp to
illuminate our location, simply by
using a few LED’s.

7. 1> More efficient than indigenous PV cells.
2> Capable of generating huge amount of power from a small cross-sectional area as
compared to conventional solar panels.
3> It can collect energy from moon even during night hours which conventional solar
panels cannot do.
4> Highly portable.
5> Highly resistant to wind, rain and storms.

8. 1> It is expensive.
2> Dual axis tracking system is costlier and has low reliability.

9. 1> Such a model, though expensive but it is eco-friendly and adaptable to various uses.
2> Future generation largely depends upon such renewable energy based systems for
their electricity demand and other uses.
3> To curb the pollution from fossil fuel run automobiles, electric vehicles will soon
become popular and replace the conventional automobiles. Such ones are largely
dependent upon these alternative energy models for consumption as fuel.
4> Future cannot be seen but it can be predicted. Finally I conclude with the saying that
very soon, such spherical sun power generator will become highly popular as an
efficient , eco-friendly & alternative energy Sun power generator.
