The term cryogenics derives from the Greek kryos, for icy cold. The upper limit that characterizes the cryogenic region of the temperature scale is subjective. If the delimitation criterion takes into consideration practical reasons, then this upper limit can be established at a higher than usually declared value (120 K) in order to include natural gas fuel liquefaction. The cryogenics region of the temperature scale 0–120 K can be divided into sub regions according to the criteria of the cryogenic method and refrigerant (known as crycoolers) as follows: (more…)

Energy exists in many forms. Some of energy forms are simple to use and identify as energy. But other forms of energy can not be seen until the energy released. Some forms of energy like light and sound, they carry energy from one place to another. There are also vibrating objects that carry the kinetic energy that makes the sound. The energy passes through the wave where the wave was originated. The higher the wave, it gives more energy. Light is also one form of energy. A light beam or light ray brings out energy from where there was light. This energy is often referred to as radiation energy. (more…)

As the name may suggest, a perpetual motion machine is a device used to provide cost free energy and if used well, it can be available for all human beings. Well, to begin with, it’s important to understand that it’s very difficult to understand, rather to conceptualize a perpetual motion machine because it can take decades to create it. Still on point, there are very many contradicting theories as to how one can come up with a perpetual motion (more…)
