Future of Solar Power

Introduction to the Future of Solar Power:

We can define solar energy as the limitless and as well as the clean source of energy from the sun.

The future of our solar power or energy  depends on several factors. The various factors are discussed below:

The future of solar power depends primarily on one of the factor that is its cost of production. As the  renewable energy that is  coal and other fossil fuels are much cheaper when compared with the solar power production.

Having problem with Formula for Potential Energy keep reading my upcoming posts, i will try to help you.

But the scientists are predicting grid parity. It is the point where the cost of the solar power will be equivalent to the cost of the renewable based energy. Grid parity has been achieved already that is California which produces approximately 45 kWh by using commercial solar panel rooftop systems. We can also develop grid parity for residential places to get power from the solar system as the renewable energies are getting depleted. But we will have to wait to use the solar power till the cost of solar power gets dropped or cheaper or cost effective than the renewable resources which we are using now.

As it is not cheaper or due to some technical limitations the use of solar energy is difficult now. But it will surely replace other power resources which we are using now in future by using giant solar collectors in space which can be used by grid.

Most of the small devices such as the mobiles we are using the solar power to recharge it. The price of the solar power will get reduced when all the peoples will start to use the solar power in our home and all places. Solar cars which we are using are environment friendly as it do not make the environment worst.

Global warming problems can be reduced when we will use the solar power in all the places and will make the environment cleaner.


Problem facing the future of solar power


The first problem which we are facing in the future of solar power is the the large space required to construct or build the solar power plants which will comprised of solar panels to store the energy which can be used by the grid. The construction of the new buildings with the solar panels fitted on top of the roofs so that the solar power can be easily used by the people.

It is not economical to produce such a large amount of power from sun.

The solar energy cannot be used directly from the sun.

Looking out for more help on What Does the Law of Conservation of Energy State in physics by visiting listed websites.

How to produce solar power


The solar energy is converted into electrical energy by the photo voltaic cells which can be used for domestic requirements. The electrical energy produced from the sun during the daytime is stored in the battery which can be used in the form of direct current. The inverter is used to convert DC supply to AC supply of 110V to power all the domestic lighting's and appliances.

As the solar energy is available directly from the sun freely, we do not have to bear any costs of the fuel to produce electricity from solar power and the maintenance cost of this very less almost zero.

The another problem which we are facing is that PV cells can generate only small amount of electricity and to increase this amount of power we have to use large layers of silicon slices in cells.

The Crust of the Earth

Introduction to crust of earth:

In the ancient time when the earth was formed it was very cold. This earth is called as the primitive earth. As more and more planetesimals collided with the primitive earth and stuck to it, their kinetic energy got converted into heat. Radioactive disintegration of the elements, such as Uranium, Thorium etc and contraction of earth due to gravitational force also heated the primitive earth. This heating of primitive earth gradually raises its temperature and the primitive earth melted. The molten material of the earth then began to reorganize into layered structure under the influence of gravity. During the formation of layered structure the lighter molten rose up to the surface to make the earth’s crust.


Description on crust of the earth:


There are three major layers of earth out of which the uppermost layer is called the crust of the earth. The thickness of the crust of earth varies from place to place. It lies between 35 km to 60 km under continents and about 10 km under oceans. The ocean crust is different from the continental crust. The ocean crust is made up of basalt, diabase and gabbro. The continental and the ocean crust float on the second layer of earth called mantle.   The crust of the earth generally composed of lighter elements. About 75% of the earth’s crust is covered with water. The crust of the earth is composed of igneous, metamorphic and sedimentary rocks. The crust of the earth occupies the earth’s volume by less than 1%. The average density for the upper crust lies between 2.7 gram per cubic centimeter and 2.74 gram per cubic centimeter. The average density of the lower crust lies between 3.0 gram per cubic centimeter and 3.25 gram per cubic centimeter. The temperature of the crust of the earth increases with the depth. The temperature of the crust of the earth lies between 200° C to 400° C.  The temperature of the earth’s crust increases by 30° C for every kilometer

Understanding specific heat equation is always challenging for me but thanks to all science help websites to help me out.

Conclusion on crust of the earth:


Most of the rocks in the crust of the earth formed before 2.5 billion years ago. The interior crust of the earth makes up lithosphere. The lithosphere is converted into tectonic plates.

What is Microwave Technology

Introduction microwave technology:

The microwaves is a part of electromagnetic spectrum. Microwaves are the electromagnetic waves of frequency range 300 MHz to 300 GHz. They are produced by special vacuum tubes such as klystrons, magnetrons and Gunn diodes. There are several uses of the micro waves in the daily life. Let us discuss about the technology of the micro waves. Microwaves is used in the communication system. It is essential for carrying out all weather operations safely,used in military air crafts and for the telephonic communication.



Micro-wave Technology


The basic principle of working of the microwave is to create micro wave radiation of suitable frequency in the working space.This radiation may match the resonant frequency of rotation of water molecules which is about 3 GHz. In this situation, the energy from the waves is transferred efficiently to the kinetic energy of molecules. The microwave of this frequency is of energy equivalent to heating up water molecules. When microwaves of this particular frequency fall on food item containing water like fruits, vegetables, meat, cereals etc the water molecules absorb these radiations. Their energy increases. These molecules share their energy with neighboring food molecules. In this situation energy the Micro-wave is transferred efficiently to the kinetic energy of molecules.

I have recently faced lot of problem while learning Momentum Equation, But thank to online resources of science which helped me to learn myself easily on net.

Uses of Micro-waves


The microwaves which are used in oven, we use the porcelain container containing food for cooking remains unaffected and cool where as only the food items get heated. It is so because the large molecules of porcelain container vibrate and rotate with much smaller frequency then that of microwave and thus absorb Micro-waves. Micro waves are also used in RADAR systems so that it can detect the air craft’s and other flying objects.  The very first microwave oven has a weight of about 750 pounds or more than it. The height of this microwave is more than 5 feet and came in the market in 1947. After 1960 the microwave oven is used in the domestic sectors. It reduces the time to cook the food.

Geothermal Alternative Energy

Introduction on geothermal alternative energy:

The earth from within is very hot. The heat inside the earth, under favorable conditions can be utilized as the source of energy. This energy is called Geothermal Energy. As Geo means Earth and Thermal means heat. Thus Geo-thermal energy can be defined as “the heat energy from hot rocks present inside the earth”.


Origin of geothermal alternative energy:


We know that deeper regions of earth’s crust are very, very hot. In these regions, the rocks melt to form magma. Geological changes in some regions of the earth push up magma upward. This magma is very hot and collects at some depth below the surface of the earth. The places under the surface of earth, where the hot magma collects at fairly less depths, are called hot spots of the earth. These hot spots are sources of geothermal energy.


Harnessing of geothermal alternative energy:


1. In some geological regions of the earth, the underground water comes in contact with hot spots and change into steam. The steam gets trapped in between the underground rocks and gets compressed to high pressure. This steam coming up at high pressure is used to run turbine connected to the generator. This produces electricity.

2. In some places, the steam does not get trapped. Instead it forces its way up through the cracks in the rocks along with hot water and gushes out from the surface of the earth to form Natural geysers.

3. In some geological places, there may be hot spots, but the underground water does not come in contact with them. In such regions, two holes are made in the earth crust. Through one hole is pumped in cold water. The cold water on coming in contact with hot spot changes to super heated steam, which emerges out from the other hole. The steam is then made to run a turbine coupled with generator to produce electricity.

Wind Energy for Homes

Introduction to wind energy:

Wind energy:- As we are very much familiar with the term wind energy ,wind energy is the energy produce by wind power. This is very old way of producing energy from natural phenomenon. It is a convection current which is produce by the uneven heating of the earth surface because of this wind always changes its direction and speed continuously and the pattern in which wind changes its speed and direction in given places is fairly constant through out the year. Wind blows because hot air want to come on upper side and cold air will stay at the lower level and because of this air blow at very faster speed and we can utilize this flow of air in different purposes.


Wind energy for homes


Wind energy for homes: We can use wind energy for the moving of wind turbine to produce electricity and we can easily use electricity for our different purposes at our home. We can also utilise wind turbines for grinding grains and pumping water for house hold purposes, and we can also setup our own wind generator by which we can produce electric power only for our use and it will be very cheap method to produce such a important form of energy.

These are the house hold machines which we can easily run with the help of wind energy and we can use it for multi things at the same time. so we can see here how much wind energy is important and how we can utilise wind energy in a good way and effective way.


Understanding Formula for Gravitational Potential Energy is always challenging for me but thanks to all science help websites to help me out.

Advantages of wind energy for homes



We can use it for number of years if you setup it once.

This is one of the most cheapest source of energy and any body can afford it easily, so charges are very affordable.

We can store energy which we are producing by wind energy if our house hold requirement is down

This is natural phenomenon of producing energy so we need not depend on any body for our energy sources.

The only disadvantage of wind energy for homes is that only knowing person can handle it as it is very easy to handle but preknowledge is very important to handle it and we should know how it will give you maximum output by very less input, so knowledge of how to produce wind energy is very important.

Directional Compass

Introduction for directional compass:

A Directional compass is the device ,which gives the direction towards any sides,i.e. East ,West,North,South. This is very useful for us,in the sense  of moving to different places.It is a kind of device which is always found with the kind of different people who loves and like to visit different places.The reading a compass is not so difficult to see ,such very hard work to do as it is something which depends on the way we place the compass there is the a proper format to do all this prospect .When we place it,the compass gives the direction with degree also.The degree which may be in the form of  15 degree or may be in the form of ratio.There are different types of compass , one is the analog which will be place in the direction manually and the other is one which reads the direction automatically.The analog one is available in the market for normal people.Other is digital used for research purpose.I like to share this Newtons 3rd Law of Motion with you all through my article.

The compass are also of many type one is the analog which is place in the direction manually and other is one which reads the direction automatically.The analog one is  available in the market for a lesser cost.Other one is digital compass which is mainly used  for scientific activities,for research purpose,military and navigation purpose, and for surveying.There are enhanced functions are there in digital compass such as altitude measurement,atmospheric measurement etc developed by various sensors and electronic system which serves the purpose


Advantages of Using Directional Compass


The person will never lose his way.

The thing which is place some where Far can be found easily.

It useful when the people or group of members has gone for any mission.So the compass gives the direction about the side and degree in mountains.

The other profit is the compass is very easy to read and give the direction according to the place.

It is better to use a digital compass which will not betray in the way of  showing the direction.


Properties of a Compass


A good compass should not be inclined to any on the side.

The compass should be able to differentiate between the poles and normal place.

There are other constraint about the kind of land and angle the digital compass although has all the quality.

Milky Way Center

Introduction to milky way center:

Milky way  having a huge group of stars and spatial bodies .Our sun belongs to milky way galaxy While we look at the sky there are infinite numbers of stars. The common question that arises in our minds is how the stars are distributed in the space. Astronomers found that the stars are occurred in the huge groups. These large groups  of stars are called as the  Galaxies.

Explanation about the milky way galaxy center:

Galaxy:  This is a part of universe that has a huge group of stars and other celestial bodies nebulae, and interstellar material bound together by gravitational force is called as Galaxy.

Milky way galaxy having a  huge group of stars in the galaxy is held together by the gravitational attraction between them. A part from stars this  milky way galaxy having a huge cloud of gases at the center which  called as Nebulae (Birth place of new stars) A milky way galaxy may have planets and other celestial bodies. The minimum stars that contain in the  smallest galaxies are about 1000,000  stars  while  the  largest  contain  up  to  3000  billion  stars. It is estimated that there are around 100 billion galaxies in the universe. One important thing is Sun belongs to Milky Way Galaxy.Understanding fourth state of matter is always challenging for me but thanks to all science help websites to help me out.


Galaxy types-Milky way center

Types of galaxies:

Galaxies have different shapes and based on the shape of alignment of the stars it has divided into three types

Spiral galaxies

elliptical galaxies

Irregular galaxies.


Elliptical and Irregular galaxies


Spiral galaxies:

In a spiral galaxy the stars forms a big spiral pinwheel with radiating from the from the central hub. The Milky Way galaxy is an example of spiral galaxy. The word milky way word name derived from the Roman word “via galactic” which means the road of milk. Most of the galaxies in the milky way galaxy lie in a disc shaped region called galactic disc.

The central part of the disc is thicker and bulges on both the sides like a old fashioned sandwiched toaster. The density of stars in the bulge region is higher than the outer side. Starting from the center bulged region group of stars spread out of arms our sun is located in one spiral arms .The sun takes about 250 million years to complete one revolution around the galactic center.

Elliptical galaxies:

In an elliptical galaxy the stars are confined to a region mainly in ellipsoid volume.Here the group of stars in this galaxy shapes like egg like structure.Hence it got it names as elliptical structure. The elliptical galaxies are described by the American scientist “Hubble”.Most Elliptical galaxies are composed of older low mass stars with interstellar medium.These type of galaxies will be around 10-15% in the universe.

Irregular galaxies:

In irregular galaxy the alignment of group of stars are fashioned in a irregular manner .It doe not having a peculiar shape. Hence they got the name irregular galaxies. This type of galaxies is useful in understand the overall evolution of the galaxies. These are having a low Metallicity rate and high level of gases and seem to be the earliest galaxies that populated in the universe.
