Hydrogen Fuel Cell Cars: Worth the Investment? Hydrogen is the most abundant element in the universe‚ but only recently have people been able to harness this resource and turn it into energy. Hydrogen fuel cell cars are one such advancement made in the effort to turn hydrogen gas into electricity. Fuel cells in the car are used to convert hydrogen into an electrical current‚ and thus power the vehicle. Fuel cells convert hydrogen and oxygen into water while producing electricity.

USE ALTERNATIVE FUELS‚ SAVE PLANET EARTH We are all aware of the current state of our environment. Mother Earth is on the brink of total destruction brought about by pollution‚ irresponsible use of resources‚ and the excessive use of conventional fuel such as fossil fuel and nuclear energy. Part of the efforts to save our planet is to shift from using conventional fuels to alternative ones such as wind energy‚ solar‚ tidal‚ wave‚ oceal‚ thermal‚ dendrothermal‚ biogas and biodiesel‚ alcohol

Differences between fossil fuel and renewable energy One of the great issues facing world in the 21st century is how best to obtain the energy for supporting operations: heat and light‚ transportation‚ production and delivery of goods and services. Fossil fuel supplies nearly 90 percent of the energy‚ according to the U.S. Department of Energy. In contrast‚ only %5 is provided by renewable energy. There are several differences between fossil fuel and renewable energy. Fossil fuel are including: oil

to this dilemma. Past research has shown that hydrogen fuel cells can quite possibly replace the country’s current usage of oil while having a more positive effect on the environment. However‚ environmentalists have conducted their own contradicting research on fuel cells reflecting negative effects on the environment. Numerous articles have been published which express both sides of this debate. Although some scientists believe hydrogen fuel cells will improve the environment and rid the United States

Rockefeller and Jay Gould. They operated in coal mines throughout southern Colorado and iron mines in Wyoming and Utah. This company was known to be the first and the only steel concentration company in the west till the World War 2.through the process of vertical integration‚ the company owned more

Fossil fuels and minerals go as far back as hundreds of millions of years ago. That is before the dinosaurs. Fossils fuels were formed in the Carboniferous Period. The Carboniferous Period occurred about 300 million years ago. In this period our Earth was covered in a swampy plant life. Lots of algae and big leafy plants covered the earth. When these plants died at the bottom of these swamps and lakes ‚they formed something called peat. Then new rock was formed on top of the peat called

problems and solutions of running out of fossil fuels With the process of industrialization‚ fossil fuels have played an increasingly important role in every aspect of human live. The use of fossil fuel has shown an explosive growth in the last few decades. The term of fossil fuel refers to “coal‚ oil‚ and natural gas - fuels that were formed millions of years ago from the fossilized remains of plants or animals” (Robert‚ 2012‚ p.10). Fossil fuels supply much of the energy used by industry and

Lessening Over-Reliance on Fossil Fuels The over-reliance on fossil fuels denotes to be a serious challenge in the United States. In 2006‚ President Bush used the term “addiction to oil” elucidating how the country heavily relies on fossil fuel as a source of energy (Sarica & Tyner‚ 2013). The world is becoming more competitive‚ and America is increasing its demand on fossil fuel. The precarious state of the fossil fuel in the markets abroad raises concerns. Political and economic instabilities are

Diesel engines and unleaded fuel engines better known as gasoline engines are actually very similar. They are both internal combustion engines which is to convert the chemical energy in fuel into mechanical energy. This mechanical energy moves pistons up and down inside cylinders. The pistons are connected to a crankshaft‚ and the up-and-down motion of the pistons‚ known as linear motion‚ creates a force to the flywheel the from the flywheel to the transmission. The working principle of diesel engines
