James Watt


James Watt was born in Greenock on January 19 in 1736, the son of a ship 's chandler. He worked in his father 's shop and he developed an interest in trying to make things " work like clockwork".
In his late teens he went to London to learn to be a "mathematical and philosophical instrument maker ", and when he returned to Glasgow he got a job making instruments with Glasgow University , who gave him a place where to live and a workshop .
In 1763 John Andreson asked him to repair an early steam engine he had bought. This early model, known as a Newcomen engine, was very unefective. The cylinder (where the piston was) had to be heated when steam was admitted, and then cooled again to condense the steam. This wasted a lot of time and fuel. Two years later , while walking through Glasgow Green , Watt hit upon the idea of condensing the steam in a separate place. This removed the need for heating and cooling, making the engine faster, safer, and it used a lot less fuel. A stone in Glasgow Green marks this spot, where the industrial revolution really began.
Watt's engines were initially used for pumping water from copper mines. Later, the new cotton mills, which had been built near fast-flowing rivers to take advantage of water power , almost all switched to steam. Gradually, mills began to

James Watt

TOPIC 3 James Watt James Watt was born in Scotland. James was a delicate boy and often suffered from severe headaches. That is why he could not go to school at the age when other children did. His mother taught him to read and his father taught him writing and arithmetic. He had a very good memory and a natural love of work. When his father saw that the boy liked to do things with his hands he brought him some tools from his workshop. For hours James would take his toys to pieces and the built new things from the parts to his own design. One day James noticed that, when the water in the kettle was boiling, the power of the steam moved the lid up and down, and when he held a cold spoon over the steam, it quickly turned back into drops of water. James was sent to a private school. He became good at languages as well as mathematics. In his spare time he began to make experiments. He managed to persuade an

carry the ball. The ball is oval, not round. Each team contains 15 players. The oldest game of football in England is probably the football match which takes place at Ashburn on Shrove Tuesday every year. The game starts in the centre of the town, and the distance between two goals is two miles. The only rule is not to use motorcycles, cars and lorries in the game. In 1958 one team buried the ball. The other team didn't know and ran after them. Later first team took the ball and won. 3) JAMES WATT He was born in the small port of Greenock on the river Clyde in Scotland in 1736.

The Steam Engine

By What are they? Steam engines are the first kind of engines to see a widespread use. They were used in the early locomotives, steam boats and factories. In fact they are still used to help run nuclear powerplants. When and by who were they invented and improved? The very first steam engine was built by Thomas Savery in 1698. However, it didn't turn any wheels, instead it pumped water out of coal mines. In 1712 Thomas Newcomen introduced an improved version of Savery's engine. James Watt improved it even further and later came up with an idea on how to use a steam engine to power something with wheels. Alright, but why are they important? Steam engines are veryveryvery important because it was the dominant source of power well into the 20th century. They actually were the moving force behind the Industrial Revolution. So no steam engines = no Industrial Revolution = Middle Ages that last approximately forever, give or take a few days But how do they work?

Topic No. 3 L.5 James Watt James Watt was born in Scotland in 1736. His father was a mathematical ­ instrument maker. James was a delicate boy and often suffered from severe headaches. That is why he didn't go to school when the other children did, so his parents had to teach him. He liked mathematics and was fond of making things, so his father gave him some tools. James liked to take his toys to pieces and build new things to his own design. At the age of eighteen he decided to become a professional instrument ­ maker. It was very hard to find a teacher. But finally he found an instrument ­ maker in London who took him on as an apprentice. After a year he returned to Scotland and became a mathematical ­ instrument maker. He also made musical instruments. He was asked to repair a small steam engine which was very

In other words: It is an illusion to build new nuclear power plants in a short time. Conclusion The IEA (International Energy Agency) voiced their support for nuclear power as a viable way of meeting carbon emission targets and increasing energy security. This is something the IEA had not done before and they are not alone as the founder of Greenpeace Sir Patrick Moore, Sir David King, the UK Government's chief scientist and James Lovelock, inventor of the Gaia theory have also voiced their support for nuclear power. And of course one must add ourselves to that list of pro nuclear figures along with any readers of our Uranium Stocks Newsletter that support nuclear power.

Energy - põhjalik referaat energiast

Lights have revolutionized the way we live, work, and play. Picture 2.2. How energy is used in homes (2005) 5 Most homes still use the traditional incandescent bulbs invented by Thomas Edison. These bulbs convert only about ten percent of the electricity they use to produce light, the other 90 percent is converted into heat. In 1879, the average bulb produced only 14 lumens per watt, compared to about 17 lumens per watt today. By adding halogen gases, the efficiency can be increased to 20 lumens per watt. Compact fluorescent bulbs, or "CFLs", have made inroads into home lighting systems in the last few years. These bulbs last much longer and use much less energy, producing significant savings over the life of the bulb. Appliances such as refrigerators, washing machines and dryers are also more energy efficient than they used to be. In 1990 Congress passed the National Appliance Energy
