SOLAR BOTANICS• Solar Botanic Ltd.(SB)

• Harness power of the sun and wind-Hybrid Energy System

• Biomimicry-A visual and natural

3D structure

• Trees and plants-EHT

• Offers clean way of generating

electricity

4College of Engineering, Chengannur

NANOLEAF TECHNOLOGY

Nanoleaf

- collects THERMAL,LIGHT and WIND

energy

- leaves are distributed throughout

the artificial trees

- stem collects kinetic energy

- supply a whole household with

electricity

NANOLEAF COMPOSITION

• Nanoantenna• Nanowires(Nanothermovoltaic)• Nanopiezo(Piezovoltaic)

6College of Engineering, Chengannur

Solar botanics

NANOANTENNA

• Is an electromagnetic collector

• Receives higher frequency and shorter wavelength

• In 1972 , Bailey proposed the idea of collecting solar energy by nanoantennas

• Nanoantenna consists of 3 main parts:

1. Ground plane

2. Optical resonance cavity

3. Antenna

7College of Engineering, Chengannur

Solar botanics

• Economical alternative to PV High conversion efficiency

Wide angular reception characteristic

No need for sun tracking system

Designed to absorb any frequency of light

Not sensitive to weather conditions

Incoming EM field from the sun induces a time changing current in the antenna 8

THEORY OF OPERATION

• Spiral nanoantennas are used

9College of Engineering, Chengannur

Solar botanics

• Incident EM radiation produces electrical current in the antenna array structure

• Absorption of incoming EM radiation at resonant frequency

• At resonance mode , cyclic plasma movement of free electrons occur

• This generates alternating current

at same frequency as that of

resonance

Solar botanics

• Nanowireso Convert thermal energy

o Absorb radiation from IR

spectrum

nanowires nanopiezovoltai cells

• Nanopiezo nanowires nanopiezovoltaic cells o Twigs, branches are also infused with nano-piezo electric material

o Detects stresses and produces thousands of picowatts of energy
