Light Bulb Grolier Multimedia
1,351 wordsOn October 22, 1879 Thomas Edison created the electric light or what we know of it today as the light bulb. To make a statement like this that Thomas Edison invented the light bulb is both a huge hyperbole and a huge understatement all at the same time. A more correct view is that he perfected a practical light bulb and that his real plan and accomplishment was the invention of an electrical system to produce and distribute electrical power. He did in fact invent a light bulb with the correct fi...

Diesel Engines High Pressure
1,702 wordsEarly work Rudolf web a German engineer, conceived the idea for the engine that now bears his name after seeking a device to increase the efficiency of the Otto engine. Diesel realized that the electric ignition process of the gasoline engine could be eliminated if, during the compression stroke of a piston-cylinder device, compression could heat air to a temperature higher than the auto-ignition temperature of a given fuel. Diesel proposed such a cycle in his patents of 1892 and 1893. Originall...

19 Th Century Source Of Energy
1,612 wordsWind Power (1) One of the reasons why our civilization was able to progress technologically is because people strived to adjust surrounding reality to their own needs. Harvesting wind can serve as the best example of human ingenuity. It is impossible to say now when people first thought of using wind power. There are historical accounts of boats being equipped with sails that date as far back as 1000 B. C. Up until the middle of 19 th century; naval ships were being powered by wind. The first re...

Source Of Energy Problem Of Global Warming
1,596 words... one saying goes - the gust of wind, created by the sway of butterfly's wings, can develop into a storm. At the same time, it opens a theoretical possibility for us to influence weather, for as long as we know all weather-inducing variables. There is also another way of achieving greater reliability of wind harvesting, as the source of energy. The article Wind Power Gathers Speed, which can be found on the site of Australian Academy of Science, gives us an insight on how it can be accomplishe...

One Of The First Electric Vehicles
2,512 wordsHybrid-Electric Vehicle Through the early period of the automotive industry until about 1920, electric automobiles were competitive with petroleum-fueled cars particularly as luxury cars for urban use and as trucks for deliveries at closely related points, for which the relatively low speed and limited range, until battery recharge, were not detrimental. Electrics, many of which were steered with a tiller rather than a wheel, were especially popular for their quietness and low maintenance costs....

Large Scale Integration Long Term Effects
3,925 words# 1. The History As the computer revolution continues along at its furious pace one wonders where we are heading. Will we eventually live in an automated utopia where we lounge about, or might our creations destroy us as in the Terminator movies? Will the Internet make its vast knowledge available to all, or will it further the separation between the haves and have nots. While there are many good things that stem from computers there is a dreadful weakness. We as a nation and a world are addicte...

Federal And State Electric Utility
1,366 wordsElectricity is the principal force that powers modern society. It lights buildings and streets, runs computers and telephones, drives trains and subways, and operates all variety of motors and machines. Yet most people, despite their great dependence on electrical power, hardly give it a thought. They flip a switch, turn a key, or pick up a phone and expect the power to be there without fail. The almost-century old structure of the American electric utility industry is in need of change. Almost ...

Amount Of Power Von Neumann
3,698 wordsDevelopment of Computers and Technology Computers in some form are in almost everything these days. From Toasters to Televisions, just about all electronic things has some form of processor in them. This is a very large change from the way it used to be, when a computer that would take up an entire room and weighed tons of pounds has the same amount of power as a scientific calculator. The changes that computers have undergone in the last 40 years have been colossal. So many things have changed ...

Large Scale Integration Electronic Digital Computer
3,222 wordsHISTORY OF COMPUTERS Historically, the most important early computing instrument is the abacus, which has been known and widely used for more than 2, 000 years. Another computing instrument, the astrolabe, was also in use about 2, 000 years ago for navigation. Blaise Pascal is widely credited with building the first digital calculating machine in 1642. It performed only additions of numbers entered by means of dials and was intended to help Pascals father, who was a tax collector. In 1671, Gottf...

Fossil Fuels Global Warming
1,982 wordsThe Potential Markets Hydrogen ANALYSIS The Potential Markets For Non-Fossil Fuel Hydrogen? Hydrogen, most of it produced from fossil fuels, is already widely used in the chemicals industry, notably in the manufacture of fertilizers and petrochemicals. It would therefore be possible to substitute NFFH in this market. However, the total that could be absorbed by 2040 is unlikely to represent more than about 3 % of current total world energy demand. ? NFFH could be used to satisfy much of the dema...

Back And Forth Stimulated Emission
1,080 wordsThe light from lasers differs from ordinary light in several important aspects. Ordinary light from a light bulb travels randomly in all directions (unless the bulb is equipped with an integral reflector that directs the light). The light is thus incoherent. Even when incoherent light is directed with a reflector, it still spreads rapidly. The light from a laser is temporary and spatially coherent. This means that all of the wave-fronts of light are lined up in time and space (see Diagrams). The...

Fossil Fuel Mechanical Energy
305 wordsHydro Power My alternative power source is Hydro power. It comes from water. The oldest and simplest form was the water wheel first used in ancient Greece for grinding grain. The water wheel design was changed by Jean Victor Ponce let in the 18 th century. He made the blades curved which raised the efficiency by 70 percent. The water wheel was now called a hydraulic turbine. The turbine is a rotary engine that changes the energy of a moving stream of water to mechanical energy. Mechanical energy...
