According to one story, a Scottish boy watched the steam lift the top off his mother`s tea kettle and realized the power of steam to make machines work. That boy, James Watt, would then go on to invent the modern steam engine in 1769. Actually, the history of steam technology records the successful work of several scientists and engineers before Watt. For example, in 1698, Thomas Savery had introduced a simple steam pump to remove water from mines, and 14 years later Thomas Newcomen invented a better pump. But these pumps weren`t efficient because they used so much fuel. In 1769, the Scottish boy, James Watt, figured out a way to save three quarters of the fuel. To honor him, his last name became the name of a unit of energy.
