storage capacity of battery used in electric vehicle is very low compare to conventional fuels used in modern automobiles. The operation, performance and efficiency of motor driven electric vehicles are much better than engine driven vehicles, at the same time electric vehicles are very much environment friendly. Still electric vehicles are falling behind in the automobile industries due to the problem of storage of energy. This paper is based on the concept of charging the batteries of an electric vehicle

3/17/2011 Efficiency of Hybrid cars Have you been to the gas station lately? Have you been shocked with the high fuel prices? When the price went beyond $40 or higher you must have thought for a second to trade in your SUV for a car with a better gas mileage, or you even might have thought about global warming. The car industry has found a technology that has an answer for these questions. The answer is the hybrid car. Most of the big car manufacturers have a hybrid model on the market. You might

harmless to human beings. I. Introduction Nikola Tesla invented the Tesla Coil, a type of air-cored resonant transformer, which is used to generate high voltage and high frequency electrical currents. Tesla coils are used to produce high-voltage, low-current, and high-frequency alternating-current. It can produce higher voltages than other artificial sources of high-voltage discharges and electrostatic machines. It takes the output from a 230vAC to several kilovolt transformer & driver circuit

GREEN COMPUTING Phase-I What is Green computing? Green computing includes the implementation of best practices, such as energy efficiency central processing units (CPUs), peripherals and servers. In addition green technology aims to reduce resource consumption and improve the disposal of electronic waste (e-waste). Energy star: Energy Star (trademarked ENERGY STAR) is an international standard for energy efficient consumer products originated in the United States

electronics mostly because of its asymmetric conductance. It ideally has zero resistance in one direction and an infinite resistance in the other. The physical structure of a diode consists of a semiconducting material such as silicon or germanium which makes a p-n junction within the diode. A diode function by allowing electric current to pass in one direction which is called the forward bias direction and blocking the current to go in the opposite direction which is called the reverse bias direction
