Solar Cells

Solar cells today are mostly made of silicon, one of the most common elements on Earth. The crystalline silicon solar cell was one of the first types to be developed and it is still the most common type in use today. They do not pollute the atmosphere and they leave behind no harmful waste products.

Alternative Energy Research Paper

The world’s sources of fossil fuels are drying up faster than the earth can renew them. Fossil fuels, like coal and oil take the earth thousands of years to reproduce so an effective alternate energy source must be explored. For many years we have been running out of oil. This phenomenon is called the Hubbert peak theory also known as peak oil. Hydrogen is a great option to power an engine. To make hydrogen we can decomposition methane or using electrolysis. There are two methods: combustion, and fuel cell conversion. Nuclear power is also an option to powering a vehicle. As we all know we have to use uranium to produce nuclear power. Biofuel is a fuel that comes from biomass, living organisms, like cow manure. This area is very active, because it can convert biofuels and other fuels into fuel cells (Biofuels)

Fuel Cell Technology

This paper investigates the physics behind the fuel cells.Starting from it’s meaning ,it’s historical origin,to frequently asked questions associated with it ,then we go into some research work performed on it and try to understand it’s results .Concluding the paper with discussing our own understanding in the topic.

Children with ITP

ITP is a very rare disease that only affects 200,000 people each year, half of them are children. ITP stands for Idiopathic Thrombocytopenia Purpura. Idiopathic indicates that the cause of the illness is unknown;

Global Warming

Global warming is a very real scientific study and a part of our lives. It is an increase in the average temperature of the earth’s atmosphere due to the burning of fossil fuels and deforestation. If we ignore the facts now the results could be catastrophic.

The Sky Isn’t the Limit

If you have ever seen an episode of the 1960’s cartoon “The Jetsons”, then you should know all about the almost laughable portrayal of our future society, sporting things such as flying cars and robotic house keepers. However, according to Douglas Malewicki, an inventor as well as aerospace engineer for UniModal Transport Solutions Inc., the idea seems far from a joke. The famous inventor is considered the father of green transportation, responsible for creations like the 156-miles-per-gallon “California Commuter” cars that hold the Guinness fuel economy records for street-legal vehicles driven at freeway speeds, as well as the highly-aerodynamic human-powered recumbent bicycle. Although both inventions seem to be great contributors to the technological revolution, neither top Malewicki’s latest prototype, the SkyTran.

The Truth about Global Warming

Over the past half century our world has become more modernized than we ever thought possible. We have innovative things to make our lives quicker and more efficient including DVDs, the IPod, and the Internet. This technology has become integrated into our society and even in a way part of our lives. It has also led to increased manufacturing and production and in turn increased the CO2 output by man kind. However, is this increase substantial enough to cause a change in the Earth’s climate? Scientists have been debating this for years and have yet to come up with an answer to this question even with overwhelming evidence supporting the idea that humans are not the cause of global warming. There is too much evidence to deny that the Earth’s warming is due to a natural change in the Earth’s climate, not mankind. Past and future fluctuations in the Earth’s climate, the sun, and the energy it emits, and North and South Pole activities all prove that man made global warming is a myth that has gotten out of hand. The newspapers and television have helped push this man made global warming into what it is today.

Final Programmatic Environmental Impact Statement for Seagrass Restoration in the Florida Keys National Marine Sanctuary

The National Oceanic and Atmospheric Administration (NOAA) is a federal agency with a goal is to keep citizens informed of the ever changing environment around them. They strive to be leaders in environmental research and use cutting edge technology to do so. The NOAA has a vision of “an informed society that uses a comprehensive understanding of the role of the oceans, coasts, and atmosphere in the global ecosystem to make the best social and economic decisions.” (Lubchenco)

Wind energy in Kenya

Harnessing the natural power of the wind is by no means a new concept. Asides from sailing, wind power has been utilised for many thousands of years, principally for agricultural purposes. Basic windmills are thought to have been used in Persia (now Iran) as early as the 7th century AD. Their ability to make use of otherwise untapped energy sources without the needs and costs of other alternatives, ensured that they remained the machines of preference in several industries throughout both agricultural and industrial revolutions.
