The Submarine

Although predating the 20th century, submarines as we know them today came into being during the 20th century. With development of nuclear power, a submarine’s range and endurance become nearly unlimited effectively rendering all previous forms of naval warfare obsolete.

Antibiotics

Until Alexander Fleming discovered penicillin in 1928, almost any little bug that someone picked up was potentially fatal. Once penicillin—and later a whole range of other antibiotics—came on the scene, however, death due to bacterial infection became rare, resulting in a greatly reduced mortality rate and much longer life-span. It also rendered many scourges of the past—from small pox and typhoid to gonorrhea and syphilis—obsolete or, at least in the case of venereal disease, something easily treatable.

Nanotechnology

Nanotechnology is a fascinating technology. The microscopically small, self-replicating machines capable of puncturing the walls of a single human cell may well be a reality a few decades from now. As a next big step in human evolution, their ability to effect repairs on the human body on a microscopic level as well as repair or enhance other non-organic technologies.

Hypersonic Transportation

The airplane revolutionized travel in the twentieth century. There is no reason to believe that evolution to ever faster speeds is going to end anytime soon. In the future people will be able to fly between London and Tokyo at Mach 10 speeds and arrive at their destination in just over two hours. Today’s train can go up to 700 miles per hour. Technology has bring many new and more fast ways of travel for human.

AbioCor Artificial Heart

The AbioCor artificial heart was initially implanted into a patient in 2001. It is the first device that is completely self-contained and doesn’t require external wires or tubes. The device is powered by an internal battery that is recharged through a transcutaneous energy transmission process. Although the original version was somewhat limited in terms of operational use, the second generation product is expected to last up to five years. The ultimate goal is to develop an artificial heart that has a design life that will far outlast the recipient.

Next time somebody tells you ” You just broke my heart” tell them there is no need to worry because Abiocor has them covered. Abiocor is one of the greatest inventions of the 21st century because it has just increased the life span of patients with an irreparable damaged heart or heart failure. How? They’ve invented a fully functional heart that mimics the function of the native heart.

Cars Powered by Hydrogen

This is the most important invention of the century: people around the world dreamed about hydrogen powered cars, and they can also change completely the pollution level on our planet. These cars can function with hydrogen as fuel. It happens in the combustion chamber, and as a result, it has only a puff of water vapor. The only problem with this car is that it can be a little bit costly for everyday use.

Mechanical Pencil

The mechanical pencil was invented in 1915 by Tokuji Hayakawa (November 3, 1894-June 24, 1980). His first mechanical pencil was called the "Ever-Ready Sharp Pencil." Hayakawa had owned a metalworking shop in Tokyo, Japan, and in 1942, expanded his company and renamed it the Hayakawa Electric Industry Co.,Ltd. It was later called the Sharp Corporation (1970), and Hayakawa was appointed chairman.
