solar power enabled mobile phone technology pdf

INTRODUCTION
How many times were we stranded because our mobile phones ran out of battery? All of us would have experienced this at least once in our life time; at least once we would have forgotten to take our mobile phone charger or that we forgot to charge our phones and it gave up at a time when we needed it very badly. Some times even when we remembered to carry our charger we may not have been able to find a power outlet that we can use to charge our mobile phones. Endless situations like t ....etc

ABSTRACT
A solar cell is a semiconductor device that converts solar energy into electricity by the photovoltaic effect, representing the fundamental power conversion unit of a photovoltaic system ,works under the principle of a P-N junction that absorbs light , releases electrons and holes , creating a voltage in the cell , which is then applied to load; being environmentally aware, and with the price of living rising at an alarming rate, solar power, generating energy from the natural resources of the sun, has in recent times become quite a ....etc

ABSTRACT:

In business a product could have a shorter life if it can't win the hearts of people and showcase new technology, so take the case of Nokia, who is coming up with the Nokia Morph flexible mobile phone which the company claims include nanotechnology and would immensely benefit its end-users. The main benefit of Nanotechnology is that its components are flexible, transparent and extremely strong. The company believes this latest technology would be ....etc

;)Solar thermal power tower

ABSTRACT
The Solar power station uses the Sun's heat to make steam, and drive a generator to make electricity. The station looks a little like the Odellio solar furnace , except that the mirrors are arranged in -circles around the power tower.
As the Sun moves across the sky, the mirrors turn to keep the rays focused on the tower, where oil is heated to 3,000 degree Celsius, The heat from the oil is used to genera ....etc

download floating solar chimney technology seminar report

The Floating Solar Chimney (FSC) Technology Power Plants, are made of three major components:

A large solar collector with a transparent roof that warms the air below it, due to the solar irradiation.


A tall lighter-than-air hollow cylinder placed in the center of the solar collector that is up-drafting the warm air, through its open top to the upper atmosphere (the Floating Solar Chimney).


A series of air turbines, placed in the path of moving and up-drafting stream of war ....etc
