      What Fuels Are Used in Power Plants?

      There are many different types of power plants. Depending on the type of fuel someone wants to use determines what kind of power plant someone would build. The most powerful power plant is a nuclear power plant, but this is also the most controversial because of events such as Chernobyl and because it is difficult

    • How OnStar Works

      How OnStar Works

      OnStar was developed and deployed by General Motors for the purpose of providing fast and effective response in the event of vehicular accidents. OnStar has now been improved to provide more than the basic services. Now, it provides assistance with directions, car breakdown help as well as communications and leisure services. OnStar is a system

      How is Chemical Energy Used

      There are many different kinds of energy but the single most widely used in society as well as in nature is chemical energy. Chemical energy allows energy to be stored for later use and it is also easy to access. Without chemical energy, many of the luxuries and even basic necessities that people have grown

    • How Safes Are Made

      How Safes Are Made

      Known under the generic name of safe or safe box there is a very broad set of constructions. From simple home safes used to keep personal documents, to bank safes which include special building construction and security measures. All safes are sturdy constructions made of metal (most with different layers) and a removable part (or

    • What is a Hydraulic Excavator?

      What is a Hydraulic Excavator?

      A hydraulic excavator (digger) is a large vehicle that is designed for excavation and demolition purposes. Hydraulic excavators consist of a chassis, boom, and bucket, and move via tracks or wheels. They range in size and function, an example of which is the similar but smaller “mini excavator.” All versions are generally designed for the

    • Parabolic Mirror

      Parabolic Mirror

      Parabolic mirrors are specially shaped in order to capture and focus energy onto a single point. They also distribute energy from a single point outwards. The mirrors are a specific paraboloid type that is rotated around its axis, and is also known as a circular paraboloid. Parabolic mirrors are also referred to as parabolic reflectors

    • What is Photolithography?

      What is Photolithography?

      Photolithography is the process of making integrated circuits through optical erosion. Rather than directly cutting into an integrated circuit, photolithography is used due to its ability to perform more precise incisions. Photolithography is a highly complex technique and requires both an extremely clean substrate surface and ideal temperature conditions. It can only be used to

    • Magnetic Permeability

      Magnetic Permeability

      Magnetic Permeability is a term refers to the ability of a material to gain or maintain magnetism. When certain materials are placed in a magnetic field they become magnetized.  For example, when you take a piece of iron and rub it on a substance already magnetized or a magnet, it will become magnetized and have a

    • 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

    • How Magnets Work

      How Magnets Work

      A magnet is an object formed out of any type of material that can produce its own magnetic field. Such materials include hard magnets and soft magnets. Examples of hard magnets are neodymium magnets and refrigerator magnets which always remember the way in which they were magnetized.Examples of soft magnets are electromagnets, which can be
