The ratio of active power to apparent power in a circuit is called the power factor. For two systems transmitting the same amount of active power, the system with the lower power factor will have higher circulating currents due to energy that returns to the source from energy storage in the load.
Ruud who invented the electric water heater (automatic storage) in 1889, founded the Ruud Manufacturing Company, which is still in operation today, and pioneered the advancement of water heaters, in both the residential and commercial market. The Water Heater is still sometimes referred to as a geyser in the UK.
In 1698, English engineer, Thomas Savery patented the first crude steam engine. Savery used his invention to pump water out of a coal mine. In 1712, English engineer and blacksmith, Thomas Newcomen invented the atmospheric steam engine. The purpose of Newcomen's steam engine was also to remove water from mines. In 1765, Scottish engineer, James Watt began studying Thomas Newcomen's steam engine and invented an improved version. It was Watt's engine that was the first to have a rotary motion. James Watt's design was the one that succeeded and the use of steam engines became widespread.
