Spread spectrum clocking is a technique used in synchronous digital devices that limits the amount of electromagnetic interference or EMI that the device causes. Since synchronous digital devices often generate interference levels that are not compliant with regulations that the FCC and other agencies set, spread spectrum clocking is an essential component of most small electronics. How Spread Spectrum Clocking Works Spread spectrum clocking works by distributing the bandwidth of electronic devices across many different frequencies simultaneously rather than allowing the device to emit EMI on any single frequency. Spread Read More

Clean gas induction, commonly referred to as CGI, is a technology found in specific types of engines to reduce harmful environmental emissions and improve fuel efficiency. Clean gas induction technology is found in specific types of engines including stratified charge engines and engines using Caterpillar ACERT technology. It should be noted that this technology is found in engines that run on either diesel or gas. As stated above, clean gas induction is used by both gasoline and diesel engines; however, the process of fuel induction is different for each kind Read More

Wave power involves the ability to harness the power of the ocean's waves and use that power to generate electricity or do other types of useful work. Much like solar power, geothermal power, and wind power, wave power is known as a type of renewable energy source because nothing is consumed in the process. Also, wave power is often confused with tidal power, another type of power which is generated via the ocean. While wave power uses the actual surface waves which form in the ocean, tidal power takes advantage Read More

A direct carbon fuel cell is a cell that relies on a carbon based material as a fuel. Unlike other forms of producing energy, a carbon based fuel cell produces energy by mixing oxygen with some form of rich carbon which results in the creation of energy. The byproduct of the reaction that takes place in a direct carbon fuel cell is carbon dioxide. The reason direct carbon fuel cells are becoming the preferred method of energy creation is because it has an efficiency of 70%. While it is not Read More

Landfill energy production operates similar to the way natural gas power plants do. Landfills could produce sufficient amounts of biogas (components of which are similar to natural gas and comprised mostly of methane) which could be refined and used as fuel for many applications that need it such as power plants. Landfills have always been used as a place to accumulate and isolate various kinds of waste materials. These landfills are also sometimes used for the management of organic waste materials such as agricultural wastes. These organic materials and other Read More

Anthracite coal is a form of coal that is almost made entirely of carbon. Anthracite coal is much harder than other forms of coal such as bituminous, and is usually found in areas surrounding mountains or deep valleys. Anthracite burns much cleaner than other forms of coal due to its low pollutant content. In fact, anthracite may contain 91% to 98% pure carbon, leaving only 2% to 9% of other elements. Anthracite coal is difficult to ignite and burns with a blue, smokeless flame. Where does Anthracite Coal Come from? Read More

British Thermal Unit (BTU) is the measurement for a unit of energy equivalent to the amount needed to heat one pound of water by 1 degree Fahrenheit. A BTU is used as the standard measurement unit to express how much energy a fuel has and to quantify how much output any device that generates heat can produce. For example, dry wood is considered to have approximately 7,000 BTUs per pound. Other heat producing devices such as gas grills are measured by the total capacity of BTUs that can be produced Read More

Solar panels are technically any kind of panel that uses solar thermal energy to produce electricity. There are a variety of panel types, from those used to heat water as with solar hot water panels, to those which are used to store solar energy, such as solar thermal energy panels. Furthermore, a solar panel can be described as a photovoltaic panel, which is what is used in the professional solar power industry to generate electricity from the rays of the sun. Despite the type of solar panel being discussed, almost Read More

Simple wireless power transmission works because of the principles of magnetic resonance and magnetic induction. This power transmission system relies on two coils in range with each other and resonating at the same frequency. The coils need to be in range because the magnetic field of the source must be strong enough for the receiving coils to induce current flow. Matching resonating frequency is also needed to enable further transmission of power through magnetic induction. Modifications or an entirely new set of principles are, however, required in order to enable Read More

Wind energy is an alternative source of electricity. This technology harnesses the power of the wind. Specifically, the wind spins turbines which powers generators whose main task is to produce electricity. The wind is one of the safest and cleanest sources of renewable energy today. The concept is similar to those of windmills used for crushing grains or for irrigation. However, in the case of wind turbines, the force of the wind on the blades creates rotational motion; this motion is used to generate electricity. Wind is just a simple Read More
