SOLAR CHARGE CONTROLLERS THE BATTERY LIFE ENHANCERS

Charge controllers, also known as charge regulators are an integral part of the solar power systems and are often termed as battery life enhancers. These devices limit the amount of current drawn and fed to the batteries bank, which stores DC energy from the solar panels. Life span of a battery is curtailed if overcharged and same is the case when current is drawn in an under charge condition. The charge controller circuit is intelligent enough to tackle both these situations by allowing or suppressing amount of charge to the batteries. In case of solar systems, Most 12 volts panels…

SOLAR INVERTERS – EFFICIENT AND ROBUST SOLAR POWER INVERTERS

Solar power is one of the most convenient and readily available form of renewable energy. Scientists have devised the methodologies and technologists have created the stuff employed for conversion of heat and light of solar rays into electricity available at our home outlets. Some specialized genre of semi conductor materials that exhibits photovoltaic effect i.e. these material produce direct current in response to incident light, are used in the fabrication of solar plates combined in the form of arrays. Each single plate is a combination of a huge number of solar cells with each cell producing voltage output in the…

MAGNETIC LEVITATION BEYOND BULLET SPEED

Magnetic Levitation

Introduction Understanding the secrets of the nature and unrevealing the hidden facts is an all time profession of mankind and the beauty of which lies in its diversified horizons, characterized by the discovery of mighty galaxies to the invisible atom. One such revelation has benefited human race in the form of high speed electric trains which have shortened the days long distances to merely a few hours. The magic behind this revolution is very simple and many of you might be knowing this from elementary school level physics, yes it is the magnetic field effect of the current flowing in…

INVISIBLE WALLS – LASER WALLS

Invisible Laser Wall In most of the strategic Hollywood movies having thrilling scenes of stealing money from a bank or some other kinds of precious and valuable artifacts from some museum etc you might have observed that there are a number of security systems. Among those systems a very famous security system is Invisible Laser Wall. As we know that light has three regions in which only one region is visible to a human naked eye. That region is known as Visible Region of light. The other two regions are Infra-Red and Ultra-violet regions. These both regions are invisible to…

3D PRINTING TECHNOLOGY

The art of 3-D printing has attracted mechanical designers specially in automotive and aviation industry because it has revolutionized model prototyping. As far as vehicle design is concerned, this industry was the first to espouse 3D modeling for generating template models of vehicle body and engine parts. The simplest way to describe 3D modeling is that a digital input file results in a physical three dimensional object using a computer controlled mechanism. From modeling point of view it is the formation of an object by addition of different horizontally sliced cross sections of the actual object, combined to generate the…

THE LIGHTNING MECHANISM

lightning Mechanism

It raises many eyebrows when it comes to the subject of how lightning stroke occurs and what magic happens in the sky that blurs our vision in the form of light, makes our ears deaf in the form of sound and burns everything it encounters on earth. Perhaps lightning mechanism is the most evident and elaborated example of an electrostatic discharge. Such kind of discharges have always been the center of attention for mankind because the anger of a stroke can never go unnoticed, it can interrupt us midday or can wake us up at the night increasing our heartbeats.…

INTRODUCTION TO PIEZOELECTRIC MOTORS

The word Piezoelectric roots back to the Greek terminology Piezein, meaning to squeeze or shrink something. The research on piezoelectric materials originated in 1881 when Pierre and Jacques determined that crystals made of quartz produce an electric field when a force or pressure is applied. The inverse methodology is applied in piezoelectric motors where application of an electric stress results in a physical motion either in linear or rotary fashion. So these special kinds of electromechanical systems differ from conventional motors which employ the law or electromagnetic induction to yield motion. In modern designs ultrasonic waves serve as a source…

ARTIFICIAL INTELLIGENCE

artificial intelligence

Have you ever seen an assembly line robot at a manufacturing facility that intelligently removes faulty products, for example some kind of food item or an automobile part, from being intermingled with those marked as healthy items. If yes, then you have witnessed Artificial Intelligence being applied in real life problem solving. Most of the people think that artificial intelligence is something beyond human intelligence and systems which employ artificial intelligence perform some magic to solve problems, certainly it is not true, as artificial intelligence and neural networks are based on the human’s thought processes developed in the form of…

MOBILE PHONE RADIATIONS HEALTH RISKS

The advent of modern technology has facilitated mankind in various shapes of which one is connecting people sitting far from each other through telecommunication systems. Over the past ten to fifteen years the use of cellular phones has increased exponentially touching the numeric value of 7.4 billion. A more comprehensive interpretation revealed that out of 100, 97 people have cell phones. But ease always comes at a cost, the mobile phones use electromagnetic radiation which people are directly exposed to. These mobile phone radiations have many adverse effect on our health. Research has been conducted both by world health organization…

UAVs – EVOLUTION OF UNMANNED AERIAL VEHICLES

The term unmanned aerial vehicles (UAVs), in modern age, is used to point our attention to the military utility vehicles controlled without an on board aircrew. However the applications of such kind of objects is not only limited to the military use as oil fields surveys and general purpose surveillance have also employed UAVs as an iconic tool to flourish their business. The UAVs we hear about today, have evolved through an iterative process as those developed some ninety to hundred years ago were simple and of basic type, owing to the fact that technology wasn’t that much advanced as…
