Hydrogen-Powered Cars
Technology has played an important role in the world of cars. Some people argue its most important accomplishment was making cars more efficient with gasoline and diesel. Now that the world's population is growing extremely fast, more and more people own cars. This leads to the air being heavily polluted, especially with carbon dioxide. Again it's time for technology to step up and provide us with a better, cleaner solution. The answer is a car powered by hydrogen.
Over the years, countries such as the US have become dependent on petroleum based fossil fuels. The exhaust from cars burning these energy sources has a negative impact on the environment. In fact, 83 percent of all the carbon dioxide released into the atmosphere in the US comes from automobiles. Earth's climate could be drastically changed if these emissions continue. Today, all major car companies are researching and developing ways to reduce these emissions, and they all seem to come to the conclusion of using hydrogen cars.

The electricity to run the car is produced by electrons being stripped from hydrogen fuel, located in a section of the fuel cell. Current made by the electrons runs an electric motor, which then turns the wheels. Next, the hydrogen protons combine with oxygen and other electrons to form water. This process powers the car and makes it run.
One of the great things about hydrogen is that it is very abundant. Hydrogen is one of the atoms that make up water, and in a process called electrolysis, can be extracted by sending electricity through water. When using pure hydrogen as a fuel, the environment is in no way harmed. All that is emitted...
