INTRODUCTIONNanotechnology is a revolutionary term creating new

possibilities in the fields of science, technology and industry. It is a new as well as challenging field of study.One such challenge is creating Nano-Leaves using the Solar

Botanic Technology.Nano-Leaves can be a possible

solution to the energy crisis the world is prone to face in the near future.

In this presentation I intend to discuss-

How Nano-Leaves can be made. What are their applications and

future prospects.

Artificial Nano leaves are capable of harvesting the thermal and light energy from the sun’s energy and convert it to electricity.

The stems of the Nano leaves are designed to collect kinetic energy from the wind, which they also convert to electrical energy.

BIOMIMICRY

WHY NANO LEAVES? Existing source of renewable energy, solar panels, parabolic

sun collectors, wind and tidal turbines are less efficient and expensive.

WHY NANO LEAVES?

Other sources like wind mills and solar panel are limited up to air and solar energy respectively.

Leaves convert the invisible light(radiation) to electricity.

Electrical energy

Solar energy + Heat energy + Wind energy

COMPOSITION OF A NANO-LEAF Consist Nano-photovoltaic generators.If light falls on the Nano-leaf, then  photo

voltaic produces the electricity.

COMPOSITION OF A NANO-LEAFConsist Nano-thermoelectric cells and .When the environment is hot, the thermo

voltaic layer produces the electrical energy.

COMPOSITION OF A NANO-LEAFNano leaf stems consist Nano-piezoelectric

generators (graphene coated with zinc oxide nanowires).

If leaf is getting stress due to wind or rain, then  piezoelectric layer produces the electricity.

CONSTRUCTION OF A NANO-LEAVESTwo conducting Nano sheets

One layer should be positive other should be negative

Keep positive layer over the negative with a very minute gap to create an electric field just like a battery.

CONSTRUCTION OF NANO LEAVES

Now insert the piezoelectric, thermoelectric and photovoltaic cell inside two conducting Nano sheets.

IMPLEMENTATION AND WORKING

HOW MUCH ELECTRICITY GENERATED

As we go for the production its one leaf can produce 1.25 V with a current of 100mA.

So the total power produced by the one leaf Power = 1.25*100 =0.125W.

The BROAD LEAF TREES can provide 3500 KWH to 7000KWH per year, besides providing shade, breeze and beauty.

SOLAR BOTANIC’S EVER GREEN TREES can provide 2500 KWH and 7000 KWH per year.

NANO TREE–ESTIMATED BUDGET

Possible output 2,000 – 12,000 kwh

cost/tree $12,000 - $20,000

Life span About 120,000 kwh over a20 year life span

cost effective comparison to other sources.

EFFICIENT THAN OTHER SOURCES

Production machines for these techniques can cost millions / billion dollars or more.

A major challenge for the field is the education and training of a new generation of skilled workers .

BEST PLACE TO USE NANO LEAF Six meter area of Nano leaves can

produce enough energy for an average household.

Desert: The earth has large areas of unexploited deserts which can be used to generate a massive amount of electricity.

It would protect inhabitants from sandstorms and provide constant shade form the sun.Recreational grounds and parksOffice Parking and industrial Zone- provides electricity to office, parking lights and other uses.

FUTURE SCOPE OF RESEARCH

To Use this electricity in driving the car.By Increasing the dimensions of leaves to

increase the production of electricity.To use in the heavy transport systems.To make efficient the Nano-tree for

Photosynthesis And many more.

These super eco friendly, highly efficient synthetic trees will make use of renewable energy from the sun along with wind power, which are an effective clean and environmentally sound medium of gathering solar radiation and wind energy.

CONCLUSION

By the use of these trees the energy crisis can be dealt with in an efficient, non polluting manner.
