Understanding the Field of the Invention
Have you ever watched a visible force of unbelievable energy such as a lightning storm and thought what if we could only harvest energy from such an event? Well, this invention harvests energy from the very atomic forces that create such unbelievable events as lightning and to comprehend how, together we must go on a brief journey of understanding. The understanding that energy, along with matter, constitutes the basis of all phenomena that takes place in the universe.
We shall begin by discovering what things are made of. We will investigate the atom, the smallest unit of matter, as well as the fundamental particles that it is made up of. We will explore how and why things move, as well as the forces that are required to put things in motion. Along this journey, we will learn of ways to multiply forces and facilitate certain types of work that would otherwise be burdensome, or even outright impossible, for a single human being to perform. Together we will conclude our journey of understanding with an essential review of many types of energy sources currently available, along with their advantages and disadvantages.
Democritus, a Greek philosopher born in the middle of the fifth century B.C., had a brilliant idea: it occurred to him that all things were made up of small indivisible particles, which he called atoms. Around the same time, other Greek philosophers decided that all things were the result of the combination of four basic elements: earth, air, water, and fire. Today, we know that atoms are divided and that the matter that surrounds us is a combination of many different natural elements. We continue to gain a deeper understanding of the structure of matter and the way in which atoms combine.
Today it is well known that atoms are made up of smaller particles, which in turn, can be subdivided into even smaller, more primordial particles. The atom, however, continues to be considered the smallest part of a chemical element that preserves the properties of that element. For example, a gold atom is the smallest particle that maintains the properties of gold. If a gold atom was divided, the resulting protons, neutrons, and electrons would not differ in any way from those that make up the atoms of, let’s say yourself. These three types of particles (protons, neutrons, and electrons) differ from one another, in particular, by the type of electric charge they have. The first two (protons and neutrons) form the atomic nucleus. The nucleus is made up of protons (with a positive charge [+1]) and neutrons (with a neutral charge.) There are typically about the same number of protons as neutrons. Electrons orbit the nucleus, and their charge is negative (-). They are much smaller than protons and neutrons; about 1,840 electrons collectively would have the same mass as one proton.
The electrons orbit in two shells located at different distances from the nucleus. The first and closest shell accepts only up to two electrons. The second and outer shell accepts up to eight electrons. The forces that keep the electrons orbiting the nucleus are called electromagnetic. An electrically neutral atom would have as many orbiting -electrons as protons in its nucleus because the charges equalize. A charged (positively or negatively) atom is considered unstable. For an atom to be stable, it must have eight electrons in its outer valence shell. This is the case with noble gases, which are not very reactive with other atoms (the naturally occurring noble gases are Helium, Neon, Argon, Krypton, Xenon, and Radon.)
An ionic bond is generated when electrons are transferred from one atom to another, which occurs in general between metals and non-metals. Table salt, the union of chlorine and sodium, is a good example. Sodium has one electron in its valence shell, unlike chlorine, which has seven. When sodium gives up its electron to chlorine, it is stabilized because its new Outermost shell will have eight electrons. However, it will remain positively charged. Chlorine, in exchange, obtains the electron it lacks to complete the eight in its valence shell and becomes negatively charged. The opposite charges attract and the union is sealed.
A covalent bond is when atoms join together but do not lose or gain electrons; instead, they share them. This is the case for carbon dioxide (CO2), water (H2O), and methane (CH4). Carbon dioxide, a gas we exhale, consists of one atom of carbon with four electrons in its valence shell and two atoms of oxygen, which each have six valence electrons. Thus, each atom of carbon shares two of its valence electrons with each atom of oxygen, and all three obtain the eight atoms for their outermost energy level.
A Metallic bond occurs between the metallic elements. Here, the electrons are not gained, lost, or shared; rather, they float freely in a kind of sea of electrons. This characteristic is what permits metals to be good conductors of electric current: electric current is nothing other than a current of electrons.

Newton’s first law states that an object remains at rest or in motion without changing state unless an outside force acts on it. Newton’s second law states that upon applying a force, an object changes its state (from rest to motion, a change in direction or in speed) and that the change is related to the strength of the force. The third law states that for every action there is an equal and opposite reaction. Today we recognize a Newton as a unit to measure force. A Newton is equivalent to the force that when applied to a mass of 1 kilogram, experiences an acceleration of 1 meter per second per second (s^2).
From atoms to stars and planets, the entire universe is in a constant state of motion. However, it took thousands of years for humans to comprehend this phenomenon and postulate the first laws that explain it; which were born from the acute Observation of Isaac Newton. An object needs a force to change its motion. An object in motion follows a trajectory, which depends on the type of forces that act over it. When an object’s velocity varies, we call this “acceleration”. If the variation has a constant value, then the motion is “uniformly accelerated,” or “uniformly decelerated” if the variation is negative. An object on the surface of the Earth would experience a force (resistance) that is produced by its contact with the air; this is called friction. This object’s horizontal velocity would decrease from this resistance, as its vertical velocity increases from the Earth’s gravitational force of attraction.
When two bodies come into contact, frictional forces are generated between them that act as resistance to the motion. Thanks to these forces, your shoes grip the floor, car brakes function, and we are able to grasp objects with our hands. Because friction turns the kinetic energy of bodies into heat, we can strike a match. Objects cannot change their state of rest or Motion by themselves; they require an outside force to do so. This property is termed “inertia”. Therefore, in a vacuum (such as space) away from any masses, an object in motion would conserve its motion indefinitely.
16.6 miles per second is the velocity at which the Earth travels through space relative to the Sun. However, thanks to inertia, we hardly notice it. This circular motion is easily observed in car wheels and in ceiling fans. An object on the surface of the circle is attracted to the center of the circle, which forces it to constantly change direction. This attractive force that pulls an object toward the center is called “centripetal force”. An object in a circular motion also experiences a “centrifugal force” that, contrary to the centripetal force, gives the impression of propelling it outside the circle. However, in reality, this is not a force but inertia.
The Rear Gear on this Bicycle has Fewer Teeth than the Gear at the Foot Pedals, a Good Ratio for Flat Terrain Riding
Gears are especially useful for magnifying or decreasing a force, as well as for changing its direction. If a toothed gear is meshed with another one with more teeth, then the second one will turn more slowly, but with less effort. In a bicycle, this gear relationship is used to go uphill. The bicycle feels “lighter” but requires more pedaling not to lose speed. If a toothed gear is meshed with another one with fewer teeth, then the second one will turn faster, but it will require more effect. Cyclists use this relationship to achieve greater speeds with less pedaling, although the bicycle feels “heavier.”
When force is applied to an axle, as in the case of bicycles, the speed is multiplied because the edge of the wheels spin faster. With each turn of the axle, the wheel will travel a greater distance because it has a greater circumference. If the force is applied to the edge of the wheel, then it becomes possible to multiply the force at the axle. Ninety percent is a bicycle’s energy efficiency ratio: that is to say, the percentage of energy that is converted into useful work. That of an automobile is only 25 percent.
The universe’s energy is a unified force and it is never lost. It can only adopt different forms, be transformed, and even remain latent, manifesting itself under certain conditions, as in the case of an object suspended in air that is then suddenly dropped. Light, heat, and electricity are some of the forms in which energy is manifested. In the functioning of each subatomic particle and of each living being, in the occurrence of any terrestrial or atmospheric event, regardless of its scale, energy performs an essential role.
However, it is not a thing, not something tangible. In general, when people speak of energy, they are really referring to its visible effects, such as light, heat, or motion. Energy, moreover cannot be created or destroyed. It only changes form; it is transformed. To better understand it, it is possible to classify it according to the characteristics by which it manifests itself.
MAGLEV Train Leaving the Pudong International Airport in Shanghai
This phenomenon has a microscopic origin (it arises from the spin of electrons within atoms) but it has an impact on a very big level. In fact, the Earth behaves like a huge magnet. The iron core and the currents of molten rock flowing underneath the Earth’s crust generate a magnetic field around the planet. The precise mechanism by which this field is produced continues to be a mystery to humankind. For centuries, magnets were considered magical objects. Only relatively recently has science been able to reveal their secrets.
Since the late nineteenth century, the phenomenon of magnetism has found countless applications in diverse fields. Diagnostic methods such as Magnetic Resonance (MRI) and Computerized Axial Tomography (CAT), which have revolutionized medicine, are based on the principles of magnetism. The magnetic levitation train (MAGLEV) moves without touching the rails, thanks to the repulsion caused between two like magnetic poles. This allows the train to travel at high speeds (greater than 370 miles per hour.) The intimate relationship between magnetism and electricity made possible the development of the telephone, the television, the radio, and a great number of electric devices used today.
Few disruptions to daily life exist that are comparable to a blackout of electricity. In the absence of electric lights, a working refrigerator, televisions, desktop computers, or air conditioning a blackout is probably the only time in which we truly stop taking energy for granted and take a moment to realize the importance of one of the most common types of energy in the world. The phenomenon known as electricity originates at the atomic level and has to do with the behavior and movement of free electrons (electrons separated from the atomic nucleus) in certain media. Understanding electricity begins with describing its effects.
One way to begin is to examine interactions that occur when electricity is at rest or static electricity. Static electricity can be seen at work when long hair is combed on a cold, dry day. As the comb is pulled through the hair, strands of hair standout stiffly. Some kind of force seems to pull the hair upward and toward the comb.
As explained above, in an atom there is an equal number of positively charged protons and negatively charged electrons, and such an atom is said to be neutral. If a neutral atom loses one or more of its electrons, it has an excess number of protons and it becomes positively charged. If a neutral atom gains one or more electrons, it has an excess number of electrons and it becomes negatively charged.
How does this simple atomic model relate to the hair, the comb, and static electricity? With the right conditions when your hair is combed, the hair loses electrons and the comb gains them, producing hair that is positively charged and a comb that is negatively charged. The combing action (friction) created charged objects because it tears electrons loose from your hair and transfers them to the comb. This is called electron capture, (the process in which an atom or ion passes through a material medium and either loses or gains one or more orbital electrons).
One of the most prolific minds in history belongs to Benjamin Franklin, who was a politician, printer, journalist, inventor and a founding father of the United States of America as well as a pioneer in the study of electricity. He is remembered as the scientist behind the famous experiment that demonstrated that lightning is an electric discharge and that clouds are charged with electricity. A discovery he made when he lifted a metal kite during a lightning storm.
Today we know that inside stormy clouds called cumulonimbus clouds, ice particles that are constantly in movement are often electrically charged by friction with each other. In a cloud, the positively charged particles tend to be located at the upper levels of the cloud and the negatively charged particles move to the base of the cloud. Sometimes a powerful discharge is produced between the base of the cloud, which is negatively charged, and the Earth’s surface, which is positively charged. We have labeled this phenomenon as lightning.
This makes it easy for these electrons to flow as electric energy. In insulators, the bond between the nucleus and the electrons of the atoms is strong. For this reason, the flow of electrons is either much more complex or simply does not occur.
Much like water flowing in a river, running freely from one point to another, free electrons will flow through conductor materials and manifest themselves in the form of energy. When a difference of potential energy is applied between the ends of a conductor, freed electrons will flow, thus generating electric current. In other words, a negatively charged terminal with an excess of electrons compared with a positively charged terminal that is lacking in electrons produces a difference in electron potential energy (an attractive force). When the terminals are connected via a conductor, the excess electrons will flow (transfer) to the terminal that lacks electrons, thus generating the electron current that we call “electricity”. This current allows electricity to be transported for subsequent distribution and use in electrical devices.
Electric current flows through a conductor in two ways: as a direct current or as an alternating current. In direct current, electrons flow in one direction. Today, this type of current is common in electric devices fed by batteries. In alternating current, the polarity of its terminals is repeatedly reversed (alternated) within the generator.
A Fundamental Depiction of an Electrical Circuit – Ohm’s Law: v (Voltage) = i (Current) x R (Resistance)
In the United States, power is delivered to residential homes as alternating current. For example, when a lamp is switched on, electrons (vibrate) back and forth within the filament to create light. The electrons that move in the filament are not the same electrons that were deflected in the generator at the power plant. When the lamp is turned on, it lights up instantly because the electric field produced in the generator loop travels through the circuit at close to the speed of light, roughly 300 million meters per second. As the field passes along the conductor, electrons in the conductor interact with the field. It is the electric energy carried by the field that moves the electrons in the circuit. It is energy, not the charge that flows from the electrical outlet in your home. The electric charges that move in the lamp are already in the lamp. Thus electric companies bill you not for electrons but for electrical energy. The charges on an electric bill are based on Kilowatt-hours (1,000-watt-hours.) A kilowatt is a unit of power or energy consumed per time unit. So a kilowatt-hour is a unit of energy.
Today the definition of a “Generator” is any machine by which mechanical power is transformed into electric power, this invention will alter that definition. Although limited amounts of electricity can be generated by many means, today electric power generation generally implies large scale production of electricity in stationary plants. The generating units in these plants convert mechanical energy from falling water, coal, petroleum, natural gas, and nuclear fuel to electric energy. Most of today’s large electric generators are driven either by hydraulic turbines, for conversion of falling water energy, or by steam or gas turbines, for conversion of nonrenewable fuel energy resources.
