Who made the first engine?

An engine is a unit that converts energy, usually heat, into mechanical work. For a long time, people worked by hand before the engine came to the rescue. At first they used the power of animals. Then they learned to use the power of the wind as a source of energy, which inflated the sails and turned the windmills. The mill was a kind of engine, pumping water and grinding grain. The energy of the falling water did the work of turning the water wheels.

Our entire civilization began to change when people learned to use heat as a source of energy in an engine. The first fact that the heat obtained from a fire was used to drive an engine took place about 2000 years ago. The Greek philosopher Heron made the first steam engine. However, he was too small to do any work.

In 1705, the Englishman Thomas Newcomen invented the steam engine. It was used to pump water from coal mines. However, the engine consumed a lot of fuel. In the XNUMXth century, James Watt made an improved engine. He came up with valves that worked so that no one had to stand by and operate them. The valves automatically caused the pistons to rise and fall.

In 1803, Robert Fulton used a Watt steam engine as a steamboat propulsor. In 1820, George Stephenson built a steam engine in England. The steam engine was very heavy, since the combustion of fuel took place in a furnace located separately from the steam boiler.

The gasoline engine, which was developed by the German Nicholas Otto in 1878, was the first step towards solving the problem of weight. This engine did not need a separate firebox and was much lighter than a steam engine of the same power.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

An empty glass will call the waiter 26.05.2002

American engineers, in an attempt to make life easier for drinkers, came up with an original glass with a microcircuit built into its bottom, which, when the drink level drops below a critical level, sends a message to the waiter on a pager.

Errors excluded. After all, each microcircuit has its own number, and on the dishes - a barcode.
