Four teenagers who can change our world

Children are treated with caution. They are prone to abrupt mood changes, like to attract attention and wear strange clothes. This files most often have to accept them for who they are. But some teenagers break the patterns. A new generation of young solves the problems of the modern world using advanced technology.

Below we will talk about four teenagers who are changing the world.

Keyan cave, 18, of New Orleans

Journey into the world of inventions for the cava began with the oil spill in the Gulf of Mexico in 2010. This spill resulted in the largest oil spill at sea in the history of mankind. Then the water in one of the most ecologically important bodies of water on the planet fell 4.9 million barrels (780 000 cubic meters) of oil.

Immediately after this, the children of dolphins began to die six times more often, and fishermen and scientists have reported a "frightening number" of deformed sea creatures, shrimp without eyes, fish with sores and holes.

Watching the news on TV, Kave immediately decided that this is just the tip of the iceberg of hidden damage to the ecology. She decided to find out what had really happened.

Fifteen she began to study what happens to oil when it gets to the ocean surface and found that under the influence of ultraviolet rays of the sun that forms a chemical carcinogen.

Today, it has grown to two scientific papers and of two patents on chemical methods for the detection of carcinogens. She also launched a startup Mare, who is working to dispel carcinogens, reducing their devastating impact. Her research has attracted more than a million dollars of funding.

Rifat, Sharuk, 18, India

When Sharuk was a child, he spent long hours staring into the lens of a telescope with his father. Unfortunately, Mohamed Farouk, Professor and scientist, he died when his son was still in high school.

But the love of space has transferred along with the DNA. At an early age he joined the "Space children of India" that fosters in young people a love for technology. He had a team of six person, the purpose of which for the next four years was the creation of a satellite under the leadership of founder and Director of the organization.

Every night, the teenagers discuss their plans for the video, ending almost in the morning. So there KalamSat: the easiest satellite in the world.

It weighs only 64 grams, a little more batteries. In fact, it is a 3.8-centimeter cube of a 3D-printed plastic, reinforced with carbon fibers. It contains several different types of sensors, including sensors to measure temperature, magnetism, altitude, and substances, which settle on the design when it flies through space. Also, the satellite has its own power supply and a small computer, enabling all the sensors at the right time and to store data with them.

The Plan was to bring KalamSat on suborbit and to check the behavior of reinforced plastic in microgravity. Lightweight materials that can withstand the hardships of space travel, extremely useful because the cost of sending 450 grams into space costs about $ 10,000. Upon reaching its destination, the satellite will have 12 minutes to collect data, and then will fall back to Earth into the ocean.

June 22, 2017 the device was successfully launched from the site of NASA in the walls island, Virginia.

Hannah Herbst, 18, FL

Herbst started to invent at the age of 15, dealing with the then nine-year-old boy from Ethiopia, who had no access to light. It should not surprise you: of the 1.3 billion people in the world live without electricity. Herbst came up with the idea Beacon (Bringing Electricity Access to Countries through Ocean Energy) technology, which captures energy directly from ocean waves.

The Idea Herbst was that the people usually settle near water; around 40% of the world population lives within 100 kilometers from the coast and only 10% live further than 10 kilometers from a source of fresh water, which is not to dig, such as a river or lake.

Technology is a hollow plastic tube with a propeller on one end and a hydroelectric generator on the other. When tidal energy rotates the propeller, it is converted into useful energy in the generator. After prototype development of the turbine as a computer model Herbst printed 3D-prototype that was tested on the coast.

If you scale the design, according to calculations by Herbst, Beacon needs to charge three car batteries at a time for one hour. This energy will be enough to power the water purification technology or circulatory apparatus in hospitals in developing countries.

The Invention Herbst has brought many awards, and she is currently earning a degree in computer engineering, parallel finishing high school.

Julian Rios Cantu, 18, Mexico

This inventor was only 13 years old when his mother was diagnosed with breast cancer. He watched in horror as the tumor was gaining in size, turning from rice grains to Golf ball in just six months. In the end mother both Breasts have been removed, and thus cancer was defeated.

Just a few years, Cantu has decided to protect others from this disease. Together with three friends he formed a company Higia Technologies, which develops a wearable device, can detect early signs of the disease.

The Prototype of the outer bra EVA is filled with sensors that you can attach to your regular bra and want to wear one hour a week. The idea is to study changes in skin temperature and elasticity, and these are the two main symptom of the disease. After each use, the data is sent to the application, the algorithm AI calculates the risk for each person separately.

The Device has already attracted small funding, but still far from mass production. He will undergo clinical trials. In the past similar technologies was recognized as unreliable.

But if the project succeeds, it could save millions of lives. Breast cancer is diagnosed in over two million people a year, and a quarter of them die. For successful treatment it is important the early detection of malignant processes.

Many inventors started from an early age. TV, telephone, trampolines, Braille, calculators, headphones and many more things were invented by people before reaching the 20th anniversary. Any of these guys could be the next Thomas Edison, or Elon Musk.
