10 Useful Inventions that Went Bad

Scientists are always trying to innovate to improve the world, but unfortunately there are people who use it for something bad for himself. Below is a list of 10 important discoveries and is for the good but it ended in disaster at the expense of the environment and human life.


1. Zyklon B
Fritz Haber was Jewish scientist who won the Nobel prize for creating a low nitrogen fertilizer and also make chemical weapons for the Germans in World War I. Insecticides are used for fumigation findings in rice store which is responsible for the deaths of 1.2 million people. Zyklon B was a favorite method of execution in the gas chamber during combustion.

2. Agent Orange
Arthur Galston to make a chemical that can accelerate the growth of soybean and allows it to be grown in areas with short seasons. Unfortunately, the high concentration of this material it will defoliate soybeans and function of this material is then replaced by a herbicide (weed eradication), although Galston worried about the impact on humans. This material is supplied to the U.S. government in an orange-striped barrels and 77 million liters of Agent Orange sprayed in Vietnam that caused 400,000 to 500,000 deaths and disabilities of birth defects.

3. Gatling gun    
Richard Jordan Gatling gun Gatling mencuptakan after he recorded over the deaths of Americans because of illness rather than gunfire. In 1877, he wrote: "It made me realize if I can find a tool (weapon) that the speed of his shot to make someone able to fight as a thousand people, it will menurangi number of troops needed and I feel feel will be easier to prepare meals for the soldiers. "Gatling gun used almost successfully to expand European colonial empire with army of mercilessly torturing natives with primitive weapons.

  
4. TNT
Joseph Wilbrand was a German chemist who discovered trinitrotoluena in 1863 who used to dye yellow. But not until 1902, when realizing the explosive force of TNT explosives and used as a weapon widely by both sides during World War I and World War II. Until now, no matter TNT was used in the military.

5. Gasoline containing lead   
Thomas Midgley was the man who invented Freon refrigerant CFC as a safe material to replace toxic materials such as ammonia coolant in use widely. However, that result from these materials apparently widespread damage to the ozone layer. Other popular idea is to add tetraethyl lead to gasoline are causing global health problems and death from lead poisoning. He is regarded as the man who "gave the most impact on the atmosphere than anyone else in the history of the earth."

6. Sarin Gas  
Dr. Gerhard Schrader was a German chemist who specializes in the discovery of new insecticides, hoping to make progress for the sake of fighting hunger in the world. However, Dr. Schrader is famous for the discovery of dangerous toxic gases such as sarin and tabun, and because of this, sometimes he was called "the father of poison gas. "

7. Nuclear fusion
Sir Marcus Laurence Elwin Oliphant was the first to menngetahui if the nucleus of solid hydrogen can be reacted with one another. This fusion reaction is the basis of the hydrogen bomb. Ten years later, American scientist Edward Teller explore the discovery of Oliphant to make it. However, Oliphant who just want to know the structure of the nucleus of an atom does not predict its use in the future.

8. Roket
Despite his passion and dream is to use a rocket astronomy in exploring outer space, the work of Wernher von Braun used to make the Nazi V2 rockets that killed 7250 soldiers and civilians and an estimated 20 000 workers during construction. Then, in the U.S. he made a series of rocket ICBM capable of carrying nuclear explosives as well as many who carried around the world before him save his reputation by creating the Saturn V rocket that took man to the moon.

9. Concentration Camp
Frederick Roberts, Prince Roberts first create refugee camps to provide protection to civilians who attacked the family who left his home for various reasons in the Boer War. However, when Lord Kitchener to replace Roberts as the main commander in South Africa in 1900, the British army introduced a new tactic in order to destroy the guerrilla attacks and the current growth of civilians. Kitchener initiated a plan to "get rid of guerrilla attacks in a series of gerkan systematic, organized like a sporting shoot, with success defined with a bag of dead, captured and wounded, and to wipe out the country from anything that might give food for the perpetrators of guerrilla attacks, including female and children. "The strategy was successfully captured Boer 28,000 people as prisoners of war and another 25,630 were drowned into the sea. Most of the rest of the Boer people in local camps were women and children. More than 26,000 women and children died in these concentration camps.

10. Ecstasy
Anton Köllisch make 3,4-metilendioksimetamfetamin as a result of his research in the form of the drug against abnormal bleeding. His research was ignored for 70 years to become popular among the dance club in the early 80's. And originated from the habit of Rave (dance party) in the late 80s who adopted drug Ecstasy as pilihanlah that make MDMA into four major illegal drug that kills about 50 people per year in the UK. The inventor died in World War I.
