10 Fantastic Inventions That Were Developed Much Earlier In the Past than You Think
Throughout history there has existed some extraordinary inventors like Leonardo Da Vinci who invented contraptions that corresponded to modern day technological inventions and machines. It’s interesting to note how the concept of such current day devices were conceived way before time. This is a list of 10 inventions made earlier than you could have expected.
1 Armored vehicles
Leonardo Da Vinci drew up the plans of an armored vehicle way back in the 15th century. His design was of a fighting vehicle similar to modern tanks but with a conical shape featuring cannons all around its perimeter. It needed four men to operate but the only problem was the wrong placement of gears that rendered the vehicle inoperataional which many felt was on purpose to prevent theft. In 2010, engineers fabricated the design with correct gears but it turned out to large to move on rough terrain. It was more a weapon of intimidation.
2 Analog computers
The discovery of the Greek Antikythera device in 1900 was a significant one as it was the first analog machine dating back to the 2nd century BCE. It was a complicated mechanism with 30 gears and was used as an astrological and astronomical calendar. The date could be changed with a hand crank after which the machine calculated the position of the moon, sun, moon phase, eclipse, and calendar cycles. Its technology would never be replicated until the 14th century when astronomical clocks began to be developed. The device wasn’t given importance for two years till it was leaned thoroughly to reveal itself.
3 Vending machines
Hero of Alexandria lived between 10 CE to 70CE. Among his many inventions was the first vending machine in the world which was actually operated by a coin that enabled the machine to dispense holy water. The next vending machine came about only in 1880 which was a commercial machine that sold postcards.
4 Automatic doors
Hero of Alexandria also invented automatic doors which he designed for use in temples. Priest’s only needed to light altar fires which triggered mechanisms that open and closed the doors. The heated air form the fire would create pressure that forced water into buckets; the buckets would then pull on ropes that opened the doors.
5 Programmable robots
The same man Hero was also responsible for creating the world’s first robot which was a wheeled cart that was powered by a falling weight. When a string was wound around its axle in different patterns, the cart moved in different directions. It was used in theaters to move automated objects.
6 Heat ray weapons
Greek Historian Archimedes once created a heat ray that burnt enemy ships fighting in the siege of Syracuse I 214-212BCE. The heat ray was made out of mirrors that were arranged on the shore to focus sunlight on ships. Tests carried out by MIT students in 2005 proved that it was indeed possible. Heat ray weapons are currently being developed by the US Military who have been trying to do so since 2000when they invented a machine called the active denial system which h was manly used in a non letythal way for crowd control and security.
7 Rapid, long-distance communication
France developed a network of 556 semaphore towers in 1792 for communications across the country. The idea was first conceived in 1600. The concept worked using a series of towers with pivoting shutters that were so arranged to create symbols. France developed the network that stretched across 3000 miles and used extensively in war. The French replaced semaphores with telegraph poles in 1846.
8 Psychological warfare
It was Chenghiz Khan who used innovative forms of psychological warfare which included whistkling arrows designed to scare the enemy. He even made his army appear larger than it was by tying objects to horse’s tails that stirred up a lot of dust. Every soldier was made to light three torches at night. Germany also used the whistling effect by fitting dive bombers with wailing sirens.
9 Cruise missiles
In 1918, the Kettering Bug an unmanned spacecraft was developed by the US military in 1918. It was the predecessor to cruise missiles and was made of paper Mache, wood laminated paper and cardboard. It carried a payload of 180 pound of explosives. Only 45 were produced during the war but it was stopped for fear of hitting friendly troops.
10 Military submarines
Among inventions made earlier, the first military submarine was built in England in 1620. It was submerged fr three hits during a demo but used several hoses attached to floaters to supply air to the crew. In 1720, the device used oa100 years later a Russian carpenter unraveled his idea of a military submarine to Peter the great. The design consisted of a large wooden barrel fitted with fire tubes to shoot at the enemy.
