1. Automated Teller Machine (ATM):
An automated teller machine (ATM) is an electronic telecommunications device that enables customers of financial institutions to perform financial transactions, such as cash withdrawals, deposits, transfer funds, or obtaining account information, at any time and without the need for direct interaction with bank staff. According to the ATM Industry Association (ATMIA), there are now close to 3.5 million ATMs installed worldwide. However, the use of ATMs in Australia is gradually declining – most notably in retail precincts. More details
2. Automated Bowling Pin Setter Machine:
In the early days of bowling, respotting the pins was a physically demanding job. There were actually people behind the lanes resetting the pins and sending back the balls. Automated Bowling Pin Setter MachineToday there are amazing robotic devices that do all the pin setting. The automatic pinsetter, first patented by Gottfried Schmidt, was introduced by the American Machine and Foundry Company (AMF) in 1946. This first pinsetter was a monster, weighing nearly 2 tons (1.8 metric tons) and standing 9 feet (2.7 m) tall. Modern pinsetters are but a fraction of a size of their predecessors and much more intelligent. More details
3. How Elevator Works:
The elevator is a type of vertical transport equipment that efficiently moves people or goods between floors of a building. Elevators are generally powered by electric motors that either drive traction cables or counterweight systems like a hoist, or pump hydraulic fluid to raise a cylindrical piston like a jack. In agriculture and manufacturing, an elevator is any type of conveyor device used to lift materials in a continuous stream into bins or silos. Several types exist, such as the chain and bucket elevator, grain auger screw conveyor using the principle of Archimedes' screw, or the chain and paddles or forks of hay elevators. Languages other than English may have loanwords based on either elevator or lift. More details
4. How Segway Works:
The Segway is a two-wheeled, self-balancing, battery-powered electric vehicle invented by Dean Kamen. The name Segway is a homophone of the word segue, meaning smooth transition. Computers and motors in the base of the device keep the Segway upright when powered on with balancing enabled. A user commands the Segway to go forward by shifting their weight forward on the platform, and backward by shifting their weight backward. The Segway detects, as it balances, the change in its center of mass, and first establishes and then maintains a corresponding speed, forward or backward. Gyroscopic sensors and fluid-based leveling sensors detect the weight shift. More details
5. How Tugboat Works:
A tug (tugboat or towboat) is a type of vessel that maneuvers other vessels by pushing or pulling them either by direct contact or by means of a tow line. Tugs typically move vessels that either are restricted in their ability to maneuver on their own, such as ships in a crowded harbor or a narrow canal, or those that cannot move by themselves, such as barges, disabled ships, log rafts, or oil platforms. Tugboats are powerful for their size and strongly built, and some are ocean-going. Some tugboats serve as icebreakers or salvage boats. Early tugboats had steam engines, but today most have diesel engines. Many tugboats have firefighting monitors, allowing them to assist in firefighting, especially in harborsHow. More details
6. Airport Fire Truck:
Airport fire trucks are extremely powerful machines. They offer relatively good acceleration for their size and weight, are able to negotiate rough terrain outside the airport area, carry large capacities of water and fire fighting foam, are fitted with powerful high-capacity pumps and water/foam cannons, and are capable of delivering firefighting media over long distances. They can be mounted on 4x4, 6x6, or even 8x8 wheeled chassis. In order to decrease their turning radius, the 8x8 wheeled unit may have all four front wheels steerable. More details
7. How Hyperloop Works:
A Hyperloop is a proposed mode of passenger and/or freight transportation, first used to describe an open-source vactrain design released by a joint team from Tesla and SpaceX. Drawing heavily from Robert Goddard's vactrain, a hyperloop is a sealed tube or system of tubes through which a pod may travel free of air resistance or friction conveying people or objects at high speed while being very efficient. Elon Musk's version of the concept, first publicly mentioned in 2012, incorporates reduced-pressure tubes in which pressurized capsules ride on air bearings driven by linear induction motors and axial compressors.

8. How Gas Station Works:
A filling station is a facility that sells fuel and engine lubricants for motor vehicles. Fuel dispensers are used to pump gasoline, diesel, compressed natural gas, CGH2, HCNG, LPG, liquid hydrogen, kerosene, alcohol fuel (like methanol, ethanol, butanol, propanol), biofuels (like straight vegetable oil, biodiesel), or other types of fuel into the tanks within vehicles and calculate the financial cost of the fuel transferred to the vehicle. Fuel dispensers are also known as bowsers (in some parts of Australia), petrol pumps (in most Commonwealth countries) or gas pumps (in North America). More details
9. How Clock Tower Works:
Clock towers are a specific type of building which houses a turret clock and has one or more clock faces on the upper exterior walls. Many clock towers are freestanding structures but they can also adjoin or be located on top of another building. Clock towers are a common sight in many parts of the world with some being iconic buildings. One example is the Elizabeth Tower in London (usually called "Big Ben", although strictly this name belongs only to the bell inside the tower). There are many structures which may have clocks or clock faces attached to them and some structures have had clocks added to an existing structure. More details
10. How Helicopter Works:
A helicopter, or chopper, is a type of rotorcraft in which lift and thrust are supplied by rotors. This allows the helicopter to take off and land vertically, to hover, and to fly forward, backward, and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of VTOL (Vertical TakeOff and Landing) aircraft cannot perform. The English word helicopter is adapted from the French word hélicoptère, coined by Gustave Ponton d'Amécourt in 1861, which originates from the Greek helix (ἕλιξ) "helix, spiral, whirl, convolution" and pteron (πτερόν) "wing".

11. The Large Binocular Telescope (LBT):
The Large Binocular Telescope (LBT) is an optical telescope for astronomy located on 10,700-foot (3,300 m) Mount Graham, in the Pinaleno Mountains of southeastern Arizona, United States. It is a part of the Mount Graham International Observatory. The LBT is currently one of the world's most advanced optical telescopes; using two 8.4 m (330 inch) wide mirrors, with centres 14.4 m apart, it has the same light-gathering ability as an 11.8 m (464 inch) wide single circular telescope and detail of a 22.8 m (897 inch) wide one. Its binary nature make ranking it as superlative somewhat more confusing, overall one of the largest telescopes in the world and in some measure the largest. More details
12. How Hybrid Car Works:
A hybrid vehicle uses two or more distinct types of power, such as internal combustion engine to drive an electric generator that powers an electric motor, e.g. in diesel-electric trains using diesel engines to drive an electric generator that powers an electric motor, and submarines that use diesels when surfaced and batteries when submerged. Other means to store energy include pressurized fluid in hydraulic hybrids. The basic principle with hybrid vehicles is that the different motors work better at different speeds; the electric motor is more efficient at producing torque, or turning power, and the combustion engine is better for maintaining high speed (better than typical electric motor). More details
13. Diesel Electric Locomotives:
Diesel Locomotives use electricity to drive forward motion despite the name 'diesel'. A large diesel engine turns a shaft that drives a generator which makes electricity. This electrical energy powers large electric motors at the wheels called 'traction motors'. Some locomotives use DC generators and others use AC. Modern alternating current locomotives have better traction and adhesion and are used on trains that carry heavier loads. DC is still used because it is cheaper to manufacture. To make a diesel electric locomotive power system it takes mechanical, electrical and control engineers. More details
14. Water Tower:
A water tower is an elevated structure supporting a water tank constructed at a height sufficient to pressurize a water distribution system for the distribution of potable water, and to provide emergency storage for fire protection. In some places, the term standpipe is used interchangeably to refer to a water tower. Water towers often operate in conjunction with underground or surface service reservoirs, which store treated water close to where it will be used. Other types of water towers may only store raw (non-potable) water for fire protection or industrial purposes, and may not necessarily be connected to a public water supply. More details
15. Laser Eye Surgery:
LASIK (laser-assisted in situ keratomileusis), commonly referred to as laser eye surgery or laser vision correction, is a type of refractive surgery for the correction of myopia, hyperopia, and astigmatism. LASIK surgery is performed by an ophthalmologist who uses a laser or microkeratome to reshape the eye's cornea in order to improve visual acuity. For most people, LASIK provides a long-lasting alternative to eyeglasses or contact lenses. LASIK is most similar to another surgical corrective procedure, photorefractive keratectomy (PRK), and LASEK. All represent advances over radial keratotomy in the surgical treatment of refractive errors of vision. More details
16. Global Positioning System (GPS):
The Global Positioning System (GPS), originally NAVSTAR GPS, is a satellite-based radionavigation system owned by the United States government and operated by the United States Space Force. It is one of the global navigation satellite systems (GNSS) that provides geolocation and time information to a GPS receiver anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. Obstacles such as mountains and buildings block the relatively weak GPS signals. The GPS does not require the user to transmit any data, and it operates independently of any telephonic or internet reception, though these technologies can enhance the usefulness of the GPS positioning information.

17. How Antenna Works:
In radio engineering, an antenna is the interface between radio waves propagating through space and electric currents moving in metal conductors, used with a transmitter or receiver. In transmission, a radio transmitter supplies an electric current to the antenna's terminals, and the antenna radiates the energy from the current as electromagnetic waves. In reception, an antenna intercepts some of the power of a radio wave in order to produce an electric current at its terminals, that is applied to a receiver to be amplified. Antennas are essential components of all radio equipment. An antenna is an array of conductors (elements), electrically connected to the receiver or transmitter. More details
18. How Magnetron Works:
The cavity magnetron is a high-powered vacuum tube that generates microwaves using the interaction of a stream of electrons with a magnetic field while moving past a series of open metal cavities (cavity resonators). Electrons pass by the openings to these cavities and cause microwaves to oscillate within, similar to the way a whistle produces a tone when excited by an air stream blown past its opening. The frequency of the microwaves produced, the resonant frequency, is determined by the cavities' physical dimensions. Unlike other vacuum tubes such as a klystron or a traveling-wave tube (TWT), the magnetron cannot function as an amplifier in order to increase the intensity of an applied microwave signal.

19. Fiber Optic Cables:
An optical fiber is a flexible, transparent fiber made by drawing glass (silica) or plastic to a diameter slightly thicker than that of a human hair. Optical fibers are used most often as a means to transmit light between the two ends of the fiber and find wide usage in fiber-optic communications, where they permit transmission over longer distances and at higher bandwidths (data transfer rates) than electrical cables. Fibers are used instead of metal wires because signals travel along them with less loss; in addition, fibers are immune to electromagnetic interference, a problem from which metal wires suffer. More details
20. How Quartz Watch Works:
A quartz clock is a clock that uses an electronic oscillator that is regulated by a quartz crystal to keep time. This crystal oscillator creates a signal with very precise frequency, so that quartz clocks are at least an order of magnitude more accurate than mechanical clocks. Generally, some form of digital logic counts the cycles of this signal and provides a numeric time display, usually in units of hours, minutes, and seconds. The world's first quartz clock was built in 1927 by Warren Marrison and J. W. Horton at Bell Telephone Laboratories. The world's first quartz watch, however, was unveiled by Japanese watchmaker Seiko as the Astron in December 1969. More details
