Harnessing Wind Power: Viable And Effective

With the cost (and pollution levels) of traditional energy sources such as burning coal and other combustible resources being extremely high, countries are obliged by themselves to look at other, more renewable energy sources to meet their needs. Energy from the wind is cited to solve this current energy shortage trends. To get energy from wind, we must focus on a concept known as kinetic energy. Whereas many wind projects have been turned down in many areas such as the Cape Cod wind energy project other regions are embracing such technologies. Equipment Used In Wind Power Generation Turbines turn with... Read more »

Thermodynamics In Physics And Our Environment

Thermodynamics is the field of physics that describes and correlates the physical properties of macroscopic systems of matter and energy by relating such qualities temperature, pressure, and volume. It also takes in energy, heat, and work. Thermodynamics was founded between 1850 and 1860 by R.W. Joule about the quantitative equivalence between mechanical work and heat. Thermodynamics is much neater when the absolute temperature is used. Thermodynamics correlates, with mathematical equations, information relating to the interaction of heat and work. It does not speculate as to the mechanisms involved . Thermodynamics is the science of heat and temperature. It is part of physics... Read more »

The Resistivity Meter; Applications In The Electrical And Mining Industries

Resistivity is the term used when describing the specific electrical resistance of a material. Put into lay mans terms it is a measurement of the resistance of any given material to electric current; it is normally measured using a resistivity meter. A material that has a high resistivity will impede the flow of electricity greatly while those with low resistivity will freely allow the flow of electrons. Although materials all have a unique resistivity measurement, there are certain generalisations that can be made without having to use a meter. Metals and substances such as salt water... Read more »

The Exciting Solution of a Water Powered Car

A water powered car is finally something that is achievable. In the past several years, a number of great programs have been created allowing water to be used along with gas as fuel. This means huge savings at the gas pump and a cleaner environment by cutting down on emissions. Today, gas costs way too much. The result is people are looking for ways to save money or get better gas mileage. With the announcement that there is now a way to run a car on water, it has received tons of attention. To... Read more »

Wind Energy And Other Alternative Energy Sources

There are lots of energy sources that we can harness if we only seek to research and develop the technologies needed to do so. We can get away from the fossil fuels and the old electrical grids by giving attention to alternatives to these energy sources. One of these alternative energy resources is wind energy. By wind power generation, we can reduce our energy consumption from expensive energy sources. Wind turbines continue to be developed , we can progressively generate more energy efficient and less costly. Anchored to this trend, “Wind farms” have been springing up in many nations, and they have even become more strategically designed to efficiently and effectively use wind energy that is abundant in our planet. Another... Read more »

The Truth About The Petroleum

Petroleum is the most widely used form of mobile energy and now supplies approximately three-fourths of the total energy used in the United States. It is also a major raw material from which a wide variety of products are manufactured. Petroleum is found in porous rock formations in the upper strata of some areas of the Earth’s crust. It consists of a complex mixture of hydrocarbons, mostly alkanes, but may vary greatly in appearance and composition. Petroleum Journals Online (PJO) publishes the first fully refereed e-journals of petroleum engineering. This initiative is designed to make it possible for petroleum engineers to rapidly publish peer-reviewed... Read more »

Benefits Of Buying A Telescope

One of the greatest scientific instruments of all time is the telescope. With thousands of years of effort of scientists in astronomy, today we have telescopes that are both readily available and accessible to everyone. So, what are some of the benefits of buying a telescope? * Astronomy Is A Fulfilling Hobby One of the greatest reasons for buying a telescope is that you get to embark on an amazing hobby. Astronomy is a great hobby for many reasons. It has real meaning, and shows you actual planets, stars, nebula, and even galaxies that are countless millions of light years away. It is amazing to be able to look at Saturn, our Moon, and even Jupiter right there... Read more »

First Telescope Buying Tips For Backyard Astronomy

Using a telescope in your own backyard can be one of the greatest hobbies you get into, which is both rewarding and at the same time increases our knowledge of practical astronomy. However, getting there can be problematic. Here are some tips to buying your first telescope. In this article, you will discover: * Understanding What You Want Out Of Astronomy * Setting A Budget To Buy Telescopes * Space Considerations To Think About * Getting The Telescope From There To Here * Understanding What You Want Out Of Astronomy You may have seen those nice pictures from the Hubble Space Telescope, now you want a telescope in the hope that you will see such images. Unfortunately the kind of telescopes you can buy is generally... Read more »

Alternating Current And Its Role in Electricity

AC motor is an electric motor that is driven by an alternating current. It consists of two basic parts, an outside stationary stator having coils supplied with AC current to produce a rotating magnetic field, and an inside rotor attached to the output shaft that is given a torque by the rotating field. AC motors require only three power conductors; DC motors require four. However, most AC drive suppliers recommend special shielded power cables to minimize electrical interference from the AC drive. AC motors are also fairly simple to understand. They are a little trickier to make but will need single-phase or three-phase AC power... Read more »

Biology Is Crucial Part Of Science

Biology is an intensely practical subject and both individual and group investigations are carried out, some being assessed for public examinations. The National Curriculum is broadly followed but with a pattern of progress which the department believes to be more logical, interesting and demanding. Biology is the fascinating study of life on Earth. Come along with us, as we become microscopic and journey inside a cell, discover new types of life forms, and play biology games. Biology is rich in examples of science as a human endeavor, its historical perspectives, and... Read more »
