Earth on fire-Global warming

As we all know temperature of our earth is increasing every year .span of winter is reducing and span of summer is increasing. In summer temperature creating new highs every year.it is November, in India it is the time of winter but still we are not wearing woolen. All we say “ yaar abhi tak garmi nahi gyi” and in summer we say “ yaar is baar to garmi ne hadd kar di” but we never  ask question , why ?
Global warming is not the small issue. If we don’t take corrective measure this time our earth will be on fire. Before discussing what we can do, first we need to understand its cause and effect.
There are many reasons which cause global warming but major factor which affect it is greenhouse gases major source of which is human activities.
Many gases like carbon dioxide (CO2), methane (CH4), CFC  and nitrous oxide (N2O) are known as greenhouse gases .
 Industrial Revolution has increased the amount of greenhouse gases in the atmosphere,
Major human activities activities which produce greenhouse gases
Thermal electricity and heat production produces  carbon dioxide (CO2),
Road transportation produces carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O)
Refrigeration and air conditioning equipment produces caloro faloro carbon(CFC)
What we can do?
Reduce use of electricity save as much as you can. It will help to reduce demand of electricity hence production of  (CO2)
Make it a habit of walking, or try to use bicycle of public transport as much as possible it will reduce production of  carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O) and also improve your health.
Minimize use of  AC and refrigerator it will reduce the electricity bill and help to reduce production of CFC
Plant trees which will help to consume greenhouse gases.
Save earth help to reduce greenhouse gases, your little effort can make big difference

Life Without Fuel

Fuel is a material which stores energy which can be extracted to perform desired work .
Fuel is a substance which, when burnt, i.e. on coming in contact and reacting with
oxygen or air, produces heat. Thus, the substances classified as fuel must necessarily 
contain one or several of the combustible elements : carbon, hydrogen, sulphure, etc. In 
the process of combustion, the chemical energy of fuel is converted into heat energy. 
fuel may be classified in to ways-
according to physical state - solid ,liquid , gaseous fuel
according to mode of procurement – natural and manufactured.


Natural ------------------------------- manufactured
                   
                         solid 
Wood                                            Bagasse
Coal                                               charcoal
Oil shale                                        coke
                          Liquid
Petroleum                                      diesel,Patrol
                                                      Coal tar etc
                          Gas
Natural Gas                             Coal gas,Producer gas,Water gas
                                                Hydrogen,Acetylene,Oil gas etc

  and different kind of Nuclear fuel 

But the major problem is that populations is rising day by day and the demand of these fuel is also rising. but all these kind of fuel are limited. one day they will be finished due to irresponsible use of them. this is the big question in front of us. we can't imagine life without fuel. because it is the major part of our daily life. for transportation , electricity and food we need fuel. if the fuel will be finished our life become hell. so it is our responsibility to save fuel and we need to switch to alternative source of energy.

  now we will discuss how we can save fuel.

1.switch off engine of your vehicle on red light.
2.use Public transport as much as possible.
3.use common transport to go at common destination.
4. Switch off all electric equipment when they are not in use.
5.use CFL instead of filament bulb.
6.Select the most energy-efficient appliances
7.Maintain proper type pressure to maximize your vehicle’s gas mileage.

now we will discuss about non conventional source of energy or Renewable energy

There are many kinds of renewable energy sources which can be used according to our climate or Convenience.

Solar Energy- Sun is a big source of energy. which can fulfill our energy requirement for life time. if we will be able to convert it in to desired form of energy. still we are using a few amount of solar energy with the help of solar Panel and solar cooker etc


bio Gas- In this type of energy resource, we use cow dung or kitchen waste to produce gas. which we can use in cooking. 



wind energy- in this source of energy we use power of wind to produce energy. this is limited to climatic condition of your region.

contribute in energy saving, your little effort can make big difference

S, E And T (Science , Engineering And Technology)

In this blog we will discuss different topics of Science, Engineering and Technology. we will discuss these topics in very simple language. we will take topics which will help us to improve our life. the material may be taken from different books, sites and collected from experience of different people.

First of all we will discuss what is Science , Engineering And Technology

Science- science is a systematic and organized form of knowledge. some types of science are Physics, chemistry,biology, social science etc.

Engineering- Engineering is a science which uses scientific concepts and practical knowledge to give a real shape to science.all engineering concepts are based on science.

Technology-Technology is the application of science for practical purpose.it also use many engineering concepts.

The distinction between science, engineering and technology is not always clear. 
Science is the reasoned study of phenomena, aimed at discovering enduring principles among elements of the phenomenal world by employing formal techniques such as the scientific method.
Technologies are not usually exclusively products of science, because they have to satisfy requirements such as utility, usability and safety.
Engineering is the goal-oriented process of designing and making tools and systems to exploit natural phenomena for practical human means, often using results and techniques from science. The development of technology may draw upon many fields of knowledge, including science, engineering, mathematics, and historical knowledge, to achieve some practical result.
Technology is often a consequence of science and engineering ,although technology as a human activity precedes the two fields. For example, science might study the flow of electrons in electrical conductors, by using already existing tools and knowledge. This new found knowledge may then be used by engineers to create new tools and machines, such as semiconductor, computers, and other forms of advanced technology.
