The document discusses nano trees, which are artificial trees that generate electricity through nanotechnology and biomimicry. Nano trees have photovoltaic, thermoelectric, and piezoelectric cells on nano-leaves to capture solar, thermal, and kinetic energy from wind. They can be installed in public parks, highways, homes, and other areas to provide renewable energy with advantages of being weather resistant, low cost, and zero emissions.

3. van der beek,founder of solar botanic lmtd during his
train ride to Netherlands he got the idea of generating
electricity from something that blends in a fake tree.
He places thousands of photovoltaics,piezoelectrics
and thermoelectrics on nano leaves which appears
like a plastic tree.

4. It is a naturally
occuring,
inexhaustable resource
which are replenished
on a human time scale
such as sun light,
wind,tides etc.

5. What is a nano tree?
It is an artificial tree which makes use of renewable
energy from sun,wind and which have a means of
collecting solar and wind energy .
It utilises three different energy
generation technologies such as
photovoltaic,thermoelectric and piezoelectric.

6. This is emerging form of renewable energy generated
by collecting solar and wind energy and converting in
to electrical energy.
Leaves are distributed through out artificial trees and
plants and can supply entire household with
maximum efficiency.

7. Biomimicry
 Generally artificial trees cannot carry out photosynthesis
naturally.
 Biomimicry is a developing science attempting to solve
human difficulties by adapting and implementing
nature's systems to human technology.
 This is possible by the use of nature design with synthetic
trees, shrubs ,plants and flowers with PV cells.
 Biomimicry and Nanoleaf technology are intrinsic to each
other.
 This is clean and renewable.

8.  It is made up of thermoelectrics, photovoltaics and
piezoelectrics on nanoleaves which make it resemble like
plastic tree.
 It has canopy 20 ft in diameter and 1200 sqft in area.
 It contains highly efficient thin film solar cells made of
CIGS.
 The trunk is primarily made of recycled materials and
also contain liquified waste biomass and wood processed
via steam combustion.
 The shape of the leaf is so as to capture the power of sun,
for efficient operation they are dark shade of green.

9. The petiole is
incorporated with
piezoelectric ribbons so as
to react to forces and
tension .
It is very versatile and easy
to install a twig and is
weather secured.

11. THERMOVOLTAIC ENERGY CONVERSION:
Nanoleaves absorb most of the light and reflects a
small part.
THERMAL ENERGY:
This is captured through the use of thermovoltaic
cells which convert thermal energy into electricity
by using semi conducting materials.

12. PHOTOVOLTAIC
ENERGY
CONVERSION:
LIGHT ENERGY:
Photovoltaic cells are
incorporated in the
nanoleaves.
These capture light
rays emitted by the
sun and is then
converted into
electricity.

14. KINETIC ENERGY:
It is harnessed through movement.
The movement of wind causes motion in
leaves,stems.This motion is collected by piezo voltaic
cells.
The piezo voltaic cells and the semi conducting
devices convert wind energy into electricity.
Stronger the wind, more the energy is produced.

17. Office Parking
Recreational parks, city parks
Electric vehicles
Charging
Highways
Houses
Deserts

18. Easy to install
Weather resistant
Low investment/High return
Various sizes
No emission of green house gases
Triple efficiency

19. ESTIMATED BUDGET AND OUTCOME
Possible output - 2000 -12,000KWH
Cost of tree - $12,000- $20,000
Life span - About 1,20,000 kwh
over 20 years life span
 One leaf can produce 1.25V ,100mA and power of
0.125W.

20. Nano trees Normal
electricity
The typical US family
of four would need four
trees at about $64000
for 20 years.
The same family pays
more than $100000 for
20 years.

21. CONCLUSION
These super eco friendly synthetic trees will make use
of renewable energy from sun , wind which are clean
and has wide potential.
