Top 10th Historic Inventions of 20th and 21st Century
Gone are the days when everything is done by the man. Today, every work and deed is work by the machines or with the help of machines. The machine is defined as any kind of mechanical device or appliance for doing work. Machines can be divided in two types, the simple machine and the complex machine. The simple is defined as a tools that redirected force to make work much easier, as for example levers, wedges, wheels, pulleys and inclined planes. The first tools invented by a man my simple sharp tools roughly around two million years ago. The complex machine was appeared much more recently.
The complex machine is defined as machines which convert energy from a natural source into mechanical work are called prime movers or complex machine. At 100 BC the first prime mover was appeared. In the Middle East was appeared. Later Noria, a wheel with a bucket was used by the ancient ones and then windmills from Persia were invented in 650AD. The two kinds of machine are used extensively all around the world. Here are the top ten machines of different eras.
Washing Machine That Does Not Need Water
The British Company Xerox invented a new washing system. This kind of machine saves a lot of water using nylon beads. With the help of beads the washing machines uses 90 percent less water as compare to other water machines. Meanwhile, the latest invention which is now in a development stage wants fewer detergents. This kind of washing machine provides you an opportunity that you need not to dry your clothes as well. As well as the work of this washing machine, it uses small nylon beads that eliminate strain off the clothes. Not only has this it locked them into the molecular structure of the nylon. With the help of beads you can wash hundreds of time and recycle it very easily. The company also claims that the washing machine will save 1.2 billion tons of water annually which is equally to 17 million swimming pools.
ATM Or Automated Teller Machine
The idea of creating this type of a cash machine was come in early 1900s. Luther George Simjian was the first man who created this machine which did not dispense cash.

Snowmaking is the production of snow by forcing water and pressurized air through a show gun. It is not to be done through a gun but also cannon. This procedure is done on the ski slopes. The snow cannon were invented by Art Hunt, in the early 1970’s since then the ski resorts depends on snowmaking. Snowmaking machines are usually used at the ski resorts in order to supplement natural snow. The production of snow requires low temperature, with the decrease of humidity the production of snowmaking increases. The production of snowmaking takes a lot of energy so it limitations requires.
Laptop
The computer was first introduced and invented by Charles Babbage. With the passage of time a man could not carry such a big computer everywhere so it keeps on changing its introduction. The first digital portable computer or the laptop was firstly invented by Adam Osbome in 1981. The name given to the laptop is Osborme1. It has a small screen built in it. It was book shape. Its weight was 5 lbs and the cost was $1.795 Later this invention become very popular and selling a lot. It was precursor of today’s models.
Mobile Phone
Alexander Graham Bell introduces and invented the telephone in 1876. With the passage of time this invention not only gives birth of different telephone models but also introduces and invented cell phone of mobile. Mobile is every day invention. According to the records Dr. Martin Cooper of Motorola is considered to be the inventor of the first practical mobile phone in 3rd April 1973. Since the usage of mobile or cell phone is increasing day by day. Later, this cell phone cells not only change its shape but different companies introduce it in a different way yet.
LCD Display or Liquid Crystal Display
Philo Taylor Farnsworth is the inventor of television in 1973. Later different sizes and shapes of Tele Vision was introduced and invented. The latest form of digital Television is LCD display. It is plain display and utilizes less space as compare to other older tale visions.

The first wrist watch was developed in 1970.
Vacuum cleaner
Once, the cleaning was done with the help of sweeps. But today it can be done with the help of a machine called Vacuum Cleaner. The Vacuum Cleaner was invented in 1860’s.it is a device that uses air pump to create partial vacuum to suck up dust and dirt. It can be used usually from floor, carpets, curtains and many other areas. It is used in the homes as well as in the industry and offices. It has a variety of sizes and models. With the passage of time new to newest models are introduced into the markets. It can suck hundreds and hundreds of dust before empty it.

Once, the people cool their food with the help of ice or snow. They packed their food with wood and ice. An American inventor named Oliver Evans invented a refrigerator in 1804.the Refrigerator is a process of removing and absorb the heat from the specific area and provide cooling. The water or liquid or refrigerant used in the refrigerator evaporates at an extremely low and freezing temperature.
Air Conditioner
Day by day the temperature of the earth is increasing. Willis Haviland Carrier was the first man who invented and introduces the device called Air Conditioner Unit in 1902. This device is invented to cool the heated areas. This divide use electricity to work. Now days, the Air Conditioner are used almost all around the world. Due the effects of global warming, it’s used is increasing day by day. Whenever you go to the market you will find the new to the newest models of Air conditioner.
