n 1698, the English mechanical designer, Thomas Savery, invented a steam pumping appliance that drew water directly from a well by a vacuum, then sent it up to a higher level by steam pressure. The appliance was also proposed for draining mines, but its pumping height was limited, making this impractical. It consumed a large amount of fuel compared with later engines.
The model Newcomen engine upon which Watt experimented
The solution to draining deep mines was found by Thomas Newcomen who developed an "atmospheric" engine also working on the vacuum principle. It employed a cylinder containing a movable piston connected by a chain to one end of a rocking beam that worked a mechanical lift pump from its opposite end. The top of the steam cylinder was open to the atmosphere. At the end of each stroke, steam was introduced into the cylinder below the piston, followed by water. This water condensed the steam and created a partial vacuum below the piston, drawing it down and thus raising the opposite end of the beam.
The Newcomen engine was more powerful than the Savery engine. For the first time water could be raised from a depth of over 150 feet. The first example from 1711 was able to replace a team of 500 horses that had been used to pump out the mine. Seventy-five Newcomen pumping engines were installed at mines in Britain, France, Holland, Sweden and Russia. In the next fifty years only a few small changes were made to the engine design. It was a great advancement.
While Newcomen engines brought practical benefits, they were inefficient in terms of the use of energy to power them. The system of alternately sending jets of steam, then cold water into the cylinder meant that the walls of the cylinder were alternately heated, then cooled each stroke. As each charge of steam was introduced, it would continue condensing until the cylinder approached working temperature once again. So at each stroke part of the potential of the steam was lost.
Separate condenserThe real name of James Watt's father is unknown. Although, one could say the Watt is a Junior. All we know about Watt's father is that he was a shipbuilder.
James Watt did not invent watts. The watt is a unit of power named after James Watt, a Scottish engineer who made significant contributions to the development of the steam engine. The watt is defined as one joule of energy per second.
Yes, James Watt had one sister named Janet.
No, James Watt did not receive a Nobel Prize. Watt was a Scottish inventor and mechanical engineer known for his improvements to the steam engine.
No, James Watt did not invent the light bulb. The light bulb was invented by Thomas Edison in 1879. James Watt was known for his improvements to the steam engine.

James Watt was a Scottish inventor and mechanical engineer. He improved the steam engine, developed the concept of horse power and invented the copying machine.
James Watt
James Watt's full name was James Gaius Watt.
The watt is named after James Watt for his contributions to the development of the steam engine, and was adopted by the Second Congress of the British Association for the Advancement of Science in 1889 and by the 11th General Conference on Weights and Measures in 1960 as the unit of power incorporated in the International System of Units (or "SI"). See the complete article at Wikipedia. Reference James Watt and watt (as in the measure of electrical current).

No, James Watt is not single.
Some say Edgar and some say James. This however is not helpful as I am doing a poster on him for my science class.

James Watt had 4 kids.They are Janet Watt , James Watt Junior , Gregory Watt and Margaret Watt.
