The History of Steam Power. The age of steam is etched firmly into America's historical memories through its romantic association with railroading, folk songs, travels with Mark Twain on the Mississippi and the personal experiences of generations of Americans.

About 2, years ago, Greek mathematician Hero experimented with steam power, constructing a rudimentary rotary steam engine.

A spinning ball driven by steam jets, he considered the device a toy. More than years later, two British inventors began to turn steam power into practical devices -- Thomas Savery in and Thomas Newcomen in James Watt further improved on their inventions, patenting several designs that earned him the title of father of the modern steam engine.

The age of steam lasted almost years, until the internal combustion engine and the electricity took over.

Even so, efficient steam turbines are still used today for submarine torpedo propulsion, for electricity generation by electric utilities and for naval propulsion systems. Exhibit Companion Classification of Engines Broadly speaking, an engine is a device that converts energy into useful mechanical power.

The term "engine" usually refers to heat engines -- engines that convert heat energy to mechanical energy. Heat engines usually consume fuel to produce the heat. Heat engines are divided into two categories -- internal combustion burning and external combustion.

A conventional gasoline engine is an internal combustion engine; gasoline is burned inside the cylinders to produce hot gases whose expansion moves the pistons. Steam engines are external combustion engines; fuel is burned outside the engine itself, producing high temperature, high pressure steam which them moves pistons or a rotating turbine.

When steam is formed from water, it requires about times as much volume as the water from which it is formed. The force produced by this expansion is the source of power in all steam engines.

In a confined space, such as a cylinder, the force is manifested as pressure that forces a piston back and forth in the cylinder, as steam enters from alternate ends of the cylinder.

The steam is routed to the appropriate end of the cylinder by valves actuated by the motion of the piston. In a true steam engine, work is done by steam pressure, rather than by condensation. The expansion from a liquid to a gas produces the pressure which pushes the pistons along inside the cylinders of a steam engine.

By the end of the nineteenth century, many different models of steam engines had been invented, so many in fact, that byeven traditional Oxford was accepting mechanical science as a suitable subject for undergraduates.

There was much to learn, as steam engines were everywhere. The diverse models of steam engines can be divided into three general types: Stationary factory ,locomotive trains, cars and marine ships.

Each of these three major types is further classified as to the axis of the piston shaft or turbine cylinder vertical, inclined or horizontalby the type of valve gear "D", piston, poppet or rotaryand by the number of cylinders or turbine stages used for expanding the steam single, double, triple or quadruple expansion.

Stationary engines were produced with vertical, horizontal or inclined cylinders. Railway locomotives generally had horizontal cylinders, although a few specialized types were produced with vertical or inclined cylinders.

Ships started off with horizontal cylinders driving paddle wheels, but quickly changed to vertical cylinders and pistons driving screw propellers through a crankshaft.

Early engines used the "D" shaped slide valve, but as machining skills were improved, these were replaced by poppet, piston or rotary valves. Nearly all locomotives built after used piston valves. Most large stationary engines used rotary valves, which were greatly improved by the addition of the Corliss "drop cut-off" gear.

Because steam required about 1, times the space as the water from which it was formed, the pressure in a single cylinder engine at the time the exhaust valve opened could still be quite high.

In order to gain efficiency, many engines were built with multiple cylinders that allowed the exhaust from the preceding cylinder to be expanded again in a larger secondary, tertiary or quaternary cylinder, again driving a piston.

In ships and factories, double and triple expansion engines were common, as their additional size and weight were compensated by added efficiency and lower fuel consumption. Railroads tried double expansion locomotives, but quickly found that lower weight and size were more significant benefits than fuel economy.

Steam and Safety The safety--or lack of safety--of steam was an important part of its history.So dreams are very important in life. They motivate, inspire, improve and help you in achieving any goal that you want to achieve.

It is the most important thing in life and without dreams, we will be nowhere. One of the biggest myths about dream analysis is that there’s a set of stringent rules people need to follow. But every person is unique, so there are no formulas or prescriptions. Dreams “can only be understood in the larger context of the individual’s unfolding and self-discovery,” Sumber says.

What Does the Bible Say About Dreams? We often speak of day dreaming or following our dreams in addition to our standard concept of dreaming, but here we will focus on the dreams that we have during sleep.

The Bible defines a dream in Job , "In a dream, in a vision of the night, when deep sleep falleth upon men, in slumberings upon. Good day to all and every one, today I meant to write about our ancestors, stemming from Saturdays post where I touched on the subject.

On Saturday, my spirit was annoyed and I felt like ranting a little so I did and I know the post went all over the place even though I managed to make it make sense however I needed to focus on the point at hand, but what the hell, this is a blog, and as you.

Dreams are Mysterious, bewildering, eye-opening and sometimes a nightmarish hell. Here is 20 amazing facts about dreams you might have never heard about.

"Really Achieving Your Childhood Dreams" (also referred to as "The Last Lecture") was a lecture given by Carnegie Mellon University computer science professor Randy Pausch on September 18, , that received a large amount of media coverage, and was the basis for The Last Lecture, a New York Times best-selling book co-authored with Wall Street Journal reporter Jeffrey Zaslow.
