Introduction

» Think of as many things as possible that

produce power

tide wind water sun

nuclear coal garbage

terristrial heat diesel etc…

ARTIFICIAL LEAF

ARTIFICIAL LEAF “ Artificial leaf “ is Like living leaves, this device

can turn the energy of sunlight directly into a chemical fuel that can be stored and used later as an energy source.

Working When artificial leaf placed in a container of water and exposed to sunlight it quickly begins to generate streams of bubbles: oxygen bubbles from one side and hydrogen bubbles from the other.

The two streams of bubbles can be collected and stored and used later to deliver power.

The device is made entirely of earth-abundant , inexpensive materials mostly silicon, cobalt and nickel and works in ordinary water.

STRUCTURE

The Home Will Be a Power Station and Gas Station

ADVANTAGES » H2 can then be stored and either burned or run

through a fuel cell to generate electricity.

» It can store energy in the chemical form that is the great advantage of this device over the solar panal which we use now a day.

» It is inexpensive as the materials are abundant.

Issues

» safe storing of hydrogen gas.

» Freezing in sub zero temperatures.

» The efficiency needs to be improved.

» For high performance, the cost due to huge silicon solar cell increases.

Research is Undergoing

» To increase the efficiency of this device.

» To explore the use of photovoltaic (solar cell) materials other than silicon such as iron oxide which might be even cheaper to produce.

CONCLUSION

» Our goal is to make each home its own power station.

» One can envision villages in India and other countries not long from now purchasing an affordable basic power system based on this technology.
