      Long Distance Wireless Power Transmission

      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

    • What is a Generator?

      What is a Generator?

      A generator (electrical) is a device that converts mechanical or chemical energy into electrical energy. Generators often use motors, turbines, engines, cranks, pistons, or other sources of mechanical energy. Likewise, generators may use chemicals or other materials that produce electricity when mixed or ignited. Generators do not produce electricity itself, but simply produce a flow

    • How a Fuel Cell Works

      A fuel cell is a device that produces electrical energy through chemical reaction. This energy conversion process is known as electro-chemical energy conversion. The simplest form of electrochemical device that we use in our day to day life is a battery cell. A fuel cell is different from a battery cell in so far as

    • Clean Gas Induction

      Clean Gas Induction

      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

    • How Do Nuclear Power Plants Work?

      How Do Nuclear Power Plants Work?

      A nuclear power plant works in the same way that a coal power plant works. Heat is generated which causes water to turn into steam. This steam turns a turbine which causes a generator to spin which generates electricity. However, a nuclear power plant does not use coal. Instead, the fuel of choice is uranium

    • How Wireless Power Induction Works

      How Wireless Power Induction Works

      Wireless power induction is already being used today in the form of electric toothbrushes. An electric toothbrush contains coils or loops in the toothbrush handle as well as in the base recharging unit. Because of their constant exposure to water, electric toothbrushes have to use inductive coupling as a means of recharging their batteries. Inductive

    • How Does Solar Energy Work?

      How Does Solar Energy Work?

      Solar energy is created by taking sunlight (solar thermal energy) and converting it into electricity. This conversion takes place via a medium that absorbs the solar energy and then converts it into usable electricity that can power various objects that are electrically operated. While the solar panel is not the most effective method of generating

    • What is Anthracite Coal?

      What is Anthracite Coal?

      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,

    • How Do Oil Rigs Work?

      How Do Oil Rigs Work?

      As recent events concerning oil spills in multiple locations have flooded the news, many people are wondering how oil drilling works and why something like an oil spill can happen. This article will attempt to answer these questions by explaining how the various processes of oil drilling work. What is an Oil Rig An oil

    • How Wind Turbines Work

      How Wind Turbines Work

      How a wind turbine works depends on the type of wind turbine discussed. While most people think of windmills as being the only true type of wind turbine, this is simply not the case, as there are horizontal axis, vertical axis, and various other types of "special" wind turbines in service around the world. Horizontal
