Global warming is one of the foremost problems facing our planet today. As pollution rises the ozone layer breaks down, and as the temperatures go on a constant rise glaciers and ice-caps melt. Many people have their doubts about the global warming "theory", however proof of this "t...

Introduction The environment of planet earth is heavily dependent on a stable climate. The stability of this climate has been continually compromised since the beginning of the industrial revolution. Poor pollution controls and the ever-increasing human industrial activity are causing...

This article talks about how the hydrogen economy will be coming. There are a lot of obstacles that they must surpass to form a hydrogen economy. In the year 2003, President George W. Bush announced a 1.7 billion research program to develop a vehicle that would make the air cleaner and use less oil...

As the scientific world progresses and the over-consumption of fossil fuels continues, scientists, environmentalists, and businessmen alike seek alternate forms of energy production and usage. One such alternative is viable through fuel cells. Fuel cells can power cars, trucks, and buses without emi...
