Chinese deadly fireworks
13th Through 16th Centuries. Rockets were first used as actual weapons in the battle of Kai-fung-fu in 1232 A.D. The Chinese attempted to repel Mongol invaders with barrages of fire arrows and, possibly, gunpowder-launched grenades. This invention brought war to a whole new level, as in, wiping out entire armies and stuff. -
Batteries
Alessandro Volta developed the first electrical battery. ... He built a battery, known as a Voltaic pile, made of alternating copper and zinc discs, with each pair of metals separated by flannel soaked in weak acid. Without this invention we wouldn't have things to charge. As in at the end of the day you wouldn't be worrying about your phone dying because you wouldn't have a battery anyway. -
Computers
Charles Babbage (1791-1871), computer pioneer, designed the first automatic computing engines. This brought use into a new age of technology if we would've passed that barrier and created these magnificent machines if it wasn't for them I wouldn't be typing this right now. -
black light things that make energy
Solar panel history. In 1839 Alexandre Edmond Becquerel discovered the photovoltaic effect which explains how electricity can be generated from sunlight. He claimed that “shining light on an electrode submerged in a conductive solution would create an electric current.” SAve the Planet -
We went the wrong way with this one
October 14, 1878, Edison filed his first patent application for "Improvement In Electric Lights". This invention light up our world. We use lights everyday so without them it would be like dark and stuff. -
Woah
It is noteworthy that the name "transformer" was created by Bláthy. In 1885 the ZBD model alternating-current transformer was invented by three Hungarian engineers: Ottó Bláthy, Miksa Déri and Károly Zipernowsky. (ZBD comes from the initials of their names). In the autumn of 1889 he patented the AC watt-meter. We need electricity. -
The first car to run on biofuel
Even though scientists E. Duffy and J. Patrick experimented with bio-fuels as early as 1853, the first engine created to use bio-fuel was by Rudolph Diesel. In fact, Rudolph Diesel showed the first bio-fuel car engine in Augsburg, Germany. This took step from using fossil fuels slower and produce less emissions and protect our atmosphere. -
Seeing through
He concluded that a new type of ray was being emitted from the tube. This ray was capable of passing through the heavy paper covering and exciting the phosphorescent materials in the room. He found that the new ray could pass through most substances casting shadows of solid objects. Roentgen also discovered that the ray could pass through the tissue of humans, but not bones and metal objects. Without this invention we would have a hrd time looking at bones -
Hoover Dam
Hoover Dam is a concrete arch-gravity dam in the Black Canyon of the Colorado River, on the border between the U.S. states of Nevada and Arizona. It was constructed between 1931 and 1936 during the Great Depression and was dedicated on September 30, 1935, by President Franklin D. Roosevelt. Hoover Dam generates, on average, about 4 billion kilowatt-hours of hydroelectric power each year for use in Nevada, Arizona, and California - enough to serve 1.3 million people. -
The Worlds First Nuclear Power Plant
In Obninsk Russia, the world's first nuclear power station to generate electricity for a power grid. The world's first full scale power station, Calder Hall in England, opened on October 17, 1956. The significance of these power plants was to make cleaner energy then burning fossil fuels.
