Top 10 inventions from 1800-1999

A world of possibilities

By Mogomotsi MoremiPublished 12 months ago 6 min read

There are many inventions that came about as a result of necessity and some by accident. Here are 10 unique inventions in the world:

The vacuum flask

The vacuum flask was invented to keep food and drink hot or cold. It was invented in 1892 by James Dewar, an amateur scientist who had previously invented an apparatus for cooling liquids.

The vacuum flask is made of glass and has a vacuum seal inside it, meaning that air cannot enter the container. The sealed space creates a perfect environment for storing items at different temperatures without them getting damaged from exposure to air or moisture. In addition to being used for storing food and drink, the vacuum flask can also be used to store medicines or other chemicals that need to remain at specific temperatures (e.g., vaccines).

The search engine

A search engine is a tool that helps you find information on the internet. It works by using algorithms to determine what information is relevant to your search query, and then returns that data in response.

The invention of this technology was made by Larry Page and Sergey Brin, who founded Google in 1998. A decade later, they sold their company to focus on other projects (like robotics).

The braille

The braille was invented by Louis Braille in 1824. Louis was originally a teacher of the deaf and blind, but he wanted to create an easier way for people who cannot read or write to communicate with each other.

The braille system uses raised dots made from ink to represent letters and numbers; it's still used today as a method of reading text on computers or tablets for people who are blind or visually impaired.

The telephone

The telephone is an immensely popular device that allows people to communicate with each other from a distance. It was invented by Alexander Graham Bell in 1876 and was first used commercially in 1878.

The first two-way radio communication took place between two ships at sea (on July 9th 1915). By 1917, there were nearly 1 million radio receivers in France alone!

The potato chip

If you're a fan of potato chips, then it's likely that you know the story behind their invention. The potato chip was invented by George Crum in 1853 as a joke, after he was fired from his job as chef at the Moon Lake Lodge in Saratoga Springs, New York.

Crum had been hired to make French fries for visitors at the resort but found himself bored with what they served him on a regular basis—potatoes boiled in water until they were soft enough to be cut into strips and fried into potato rolls (a popular snack item). So one day while preparing his meal on an open fire with nothing else available nearby (because everything else was being used by other staff members), he decided to use some sliced potatoes instead of just cutting them up raw like usual—and voila! You've got yourself some delicious new creation: "the crispy" treat we all know today as "the chip."

The plastic container

Invented in the 1950s, plastic containers are used for storing food, drinks and other materials. They come in different sizes and shapes such as canisters that hold oil, glass jars with lids, and bottles with dividers or compartments. These containers are made by combining various types of plastic to create a single material that can be produced at a low cost.

Plastic containers are made from polyethylene (PE), polypropylene (PP) and many other types of plastics such as PET, PS/PSS or PE/PET etc., depending on their purpose

A submarine that could travel under the sea and replace a ship above the water.

The submarine is a type of ship that can travel under the water, replacing ships that could sail above the water. It was invented by John Holland in 1620 and used for military purposes, but it eventually became popular for civilian use as well. A submarine is made up of many parts: a hull (the main part), an engine room where there are several engines with propellers on them, rooms for crew members who work inside the vessel with their own equipment such as lights and other things needed for navigation through oceans or rivers at night time when submerged below surface level so no one can see what's going on inside those spaceships!

A traffic light system invented to help people know when to cross or not.

In the early 1900s, Lester Wire (a police officer in Salt Lake City) invented the first traffic light. The invention was used to help people cross the street safely and efficiently.

The first traffic light was a red and green bulb; it was placed at an intersection where two roads intersected at right angles. When you approached this intersection from one direction, your car's headlights would shine through each colour of glass, causing them to stay lit up—this way you could tell whether or not it was safe for you to cross over onto another road. If there were no cars around when your car turned off its headlights (which happens automatically), then there would also be no lights shining through those same coloured lenses! This meant that drivers could stop anytime they wanted without worrying about being noticed by other drivers who might not have seen them yet but might still feel tempted by their presence; thus making everyone safer while still keeping things moving smoothly along at all times."

An early form of television was invented in 1926.

The first television was invented by Philo T. Farnsworth in 1926, and it was called the Image Dissector. This device used a cathode ray tube (CRT), which contained three electron guns and an image-laden screen that could be moved horizontally or vertically. The broadcast of this first TV signal began on October 2, 1928; viewers were able to see distorted images due to interference from other electrical devices.

The second-ever commercial broadcast occurred on June 12th 1932 when NBC began broadcasting its New York City affiliate station W2XBS from Rockefeller Center's RCA building at 49 East Fifty-seventh Street between Fifth and Sixth avenues in Manhattan.[1]

A Microwave oven was first used in 1946.

The microwave oven was first used in 1946. That year, the US government developed a device that could heat food from behind a window or glass door. It weighed 750 pounds and had to be installed on top of a power plant by crane because it needed so much energy to run.

The first commercial microwave ovens were first sold commercially in 1947, but they weren’t very popular at first because people thought they were too high-tech for their tastes—and maybe because their price tag was around $1 million!

There are many inventions that came about as a result of necessity and some by accident

There are many inventions that came about as a result of necessity and some by accident. Some examples include the telegraph, telephone and radio.

Inventors also have to consider who will benefit from their invention before they make it public. This can be done through testing with volunteers or animals before releasing the product into the market for sale.


The world has been a better place because of these inventions. The vacuum flask, search engine and the phone are just a few of the many inventions that have made life easier for us all.
