INTRODUCTION
 With the emerging nano technology, scientists are
working on the new concept called the nano leaves
that will help producing electricity with the help of
solar energy.
 This paper is about renewable energy and in
particular the innovative technology of artificial trees
and leaves known as BIOMIMICRY
WHAT IS BIOMIMICRY?????
 In this theory nano leaves transform light
,heat and wind energy into eco friendly
electricity.Biomimicry is a developing science
attempting to solve human difficulties by
fostering nature’s clever systems.
HOW NANO LEAVES CREATES
ELECTRICITY????
They create electricity in three ways:
 Nano photo voltaic generators in the
leaf directly convert solar energy into
electricity
 Nano thermo electric cells convert solar
heat to electricity
 Nano piezo generators convert wind
energy into electricity.
THERMAL ENERGY
 This is captured through the use of photo
voltaic cells which convert thermal energy
into electricity by using semi conducting
materials.
 There
are also tiny photovoltaic cells
incorporated in the nano leaves.These
small pv cells capture the light rays
emitted by the sun.The light is then
converted into electricity

Kinetic energy is harnessed through
movement.The wind blows motion in stems
and branches.The motion is collected via
piezo voltaic (pz)cells.The pz and semi
conducting devices convert typical ind
energy into electricity
NANO TREES OPERATION AND
WORKING:
 When outside forces like wind pushes the nano leaf back
and forth mechanical stresses appear in the petiole,twigs
and branches.When thousands of nano leaves flap back
and forth due to wind millions and millions of pico watts
are generated,the stronger the wind the more energy
is generated.

Nano leaves reflect a small part of the sunlight
that strikes them ,mostly the green light and the
rest of the spectrum is efficiently converted into
electricity. Due to unique combination of photo
voltaic and thermo voltaic in nano leaves it
converts thermal radiation into electricity.

It is a company that plans to introduce artificial
trees that make use of renewable energy for the
sun and wind. They have created what they call
“nano leaves” that produce electricity. They can
produce in a variety of real tree leaf
shapes,contain solar cells to convert sunlight to
electricity .these come as broad leaf
trees,evergreen trees or as shurbs
plants,roof ,wall carpets and fencing
BEST PLACES TO USE NANO LEAVES
 DESERT
 PARKS,RECREATION GROUNDS
 GOLF COURSES
 OFFICE PARKING AND INDUSTRIAL ZONE
 ELECTRICAL ENERGY FROM NANO LEAVES
DESERTS

THE POWER SUPPLIED BY THE TREES PLANTED IN
THE DESRT CAN BE USED TO POWER
DESALINATION PLANTS TO PRODUCE FRESH
WATER FROM SSEA WATER AND BRAKISH WATER
AQUIFERS.THEY ALSO PROVIDE SHADE AS WELL AS
PROTECTION FROM SUN WIND AND
SANDSTORMS.
 THE
ELECTICITY PRODUCED CAN BE USED TO
CHARGE ELECTRICITY POWERED GROUND AND
MAINTENANCE VEHICLES SUCH AS GRASS
CUTTERS AS WELL AS ELECTRICITALLY
POWERED HAND TOOLS.
OFFICE PARKING AND INDUSTRIAL ZONE
• Trees planted in these locations will not only
supply electrical power for the office and
industrial units but add aesthetic qualities to an
otherwise drab area,whilst providing shade from
wind and sun.
Electrical energy from nano leaves
• The photovoltaic,piezo voltaic,thermo voltaic
harvesters are linked to junction boxes, from
where they are amalgamated and fed collectively
into an inverter. This converts electricity from
direct current to alternate current. It is
estimated that a six meter area of nano leaves
canopy will generate enough electrical power to
supply an average household.
CONCLUSION

These super eco friendly synthetic trees will
make use of renewable energy from the sun along
with wind power. I express my humble opinion
that fake plastic trees are not the best way to
transform our urban landscapes. Solar nano
technology has wide ranging potential .Using
such nano technology power producing solar
products could be applied to just above any
surface downtown or anywhere. So why the need
for rows of plastic trees lining our
boulevards???????
