A fuel cell is a device that transfers the chemical energy from a fuel into electricity through a chemical reaction of positively charged hydrogen ions with oxygen or another oxidizing agent [1]. Fuel cells can produce electricity continuously until these inputs are supplied. The first fuel cells were invented in 1838. Since then‚ fuel cells have been used in many other applications. Fuel cells are used for primary and backup power for industrial‚ commercial and residential buildings and in inaccessible

Fossil Fuels which include Petroleum and Natural Gas were formed million years ago from the remains of plants and animals‚ are responsible 40% and 20% respectively for the world ’s energy. They were first discovered about 700-900 years ago‚ however since the first modern petroleum industry began in 1859‚ the demand for fossil fuels has escalated beyond our control. It had taken 50-300 million years to form‚ and yet we have managed to burn roughly half of all global oil reserves in merely 125 years

The writer believes that ethanol fuel is not a suitable alternative for gasoline‚ while the lecturer claims that passage state is not convincing and disputes those ideas presented in the passage with several proofs. First of all‚ the author asserts that the ethanol fuel would not assist to fix global warming problem. Conversely‚ the lecturer brings up the idea that augmented of ethanol fuel does not adversely affect the environment. In other

harmful gases that vehicles are giving off. Forget ethanol or biodiesel. The next big thing in automotive fuel may very well be hydrogen. Automakers rapidly are closing in on making hydrogen fuel cell vehicles an everyday fact of life‚ with several test models set to debut over the next few years. Hydrogen fuel cells to power vehicles are desirable‚ experts say‚ because hydrogen is a renewable fuel that can be used to create electricity to run cars. A chemical reaction between oxygen and hydrogen produces

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

Petroleum‚ otherwise known as petrol‚ results in pollution during every stage of production‚ this ranges from: mining and recovery to refining‚ transporting and more importantly using it as fuel. Drilling wells is responsible for direct pollution due to oil spills; consequently‚ drilling also leads to the injection of watery liquids into the wells which are later distributed as drilling mud that often cause their own toxic pollution. Furthermore‚ the transporting of such oil by tanker ships have

COLORADO FUEL AND IRON COMPANY Colorado fuel and Iron Company in 1903 the city’s main industry was known to be a large steel concentration company. This company was owned and controlled by Johan D. 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

1. What is in Gasoline? Gasoline is produced from a dark substance extracted from miles beneath the surface‚ called crude oil or petroleum. Millions of years ago‚ crude oil was created from fossil fuels of dead animals and plants that sank into the ocean’s bottom underneath rocks‚ dirt‚ and dust. Over time‚ the seclusion of corpses caused heat and pressure to increase instigating the bodies to decompose; and due to lack of oxygen‚ the remains formed mixture of chemical organic compounds made of hydrogen

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
