Jakarta, CNBC Indonesia – The development of the times is marked by the many innovations that have emerged. However, not all of these ideas were successful. There are also those that fail after launch.
There are even some that have a bad impact on health or cause fatal accidents. Hindenburg, for example, which eventually burned because of the idea of replacing helium with hydrogen.
Here are 5 innovations that ended in failure, summarized from the page time, Tuesday (29/8/2023):
1. Hydrogen Balloon
The Hindeburg designed in 1931 used hydrogen. The reason is that it can be cheaper and easier to obtain than the commonly used helium.
But hydrogen is easier to burn. This impact was experienced by the Hindenburg in 1937, where the blimp caught fire and crashed in just 36 seconds.
2. Hair Powder
Hair powder in cans is said to reduce baldness. Placed in a can, the powder is sprayed on the head and should cover the freckles on the hair. But the result of the spray is like using a can of paint.
DDT or dichloro-diphenyl-trichloroethane was discovered in 1939 and was intended as a drug against insect-borne diseases. Its discoverer, Swiss chemist Paul Hermann Muller, noted its effectiveness as a pesticide during World War II.
But DDT did have an impact on the environment because millions of pounds of this potent pesticide are dumped each year. In 1962, environmentalist Rachel Carson became the first person that the drug caused fertility and neurological problems, even poisoning birds as it started up the wildlife food chain.
Eventually the use of the compound began to decline drastically. In 1972, DDT was banned throughout the United States (US).
Auto-tune is considered a bad innovation because of its ability to change someone’s voice. This technology is known in the world of singing, because it can make someone’s voice sound very good or vice versa like a robot.
5. Red Dye No.2
This food coloring was withdrawn from the market in 1976. At that time a Soviet scientist said its use could cause cancer.
