The world population increases every day, and so does the need for energy. The only problem is that much of the energy society uses is non-renewable, meaning once a source is diminished it can no longer be used again. The solution is to use the most abundant energy source that burns bright in the sky every day, the sun. The energy given off by the sun can be harnessed to create electricity, and that electricity can be stored for later use. According to the website Altenergy, “The average star,…

I. Science Fair Question What is the speed of light in gelatin? II. Background Research Did you ever wonder how the speed of light is measured? This paper will discuss how the speed of light is measured. The terms that will discussed in this paper are the law of refraction, trajectory, Snell’s Law, and the index of refraction. Snell’s Law gives the relationship between angles of incidence and refraction for a wave impinging on an interface between two media with…

Alyssa Eaves Professor David Bergbreiter CHEM 227 22 November 2014 Dmitri Mendeleev: A Biography Today in American classrooms, the name Dmitri Mendeleev conjures up the sole image of a periodic table, secure and immutable with all its ordered numbers and letters marching along in dependable patterns. More than one hundred years ago in Imperial Russia, the name Dmitri Mendeleev would call to mind séance scandals, economic tariffs, hot air balloon rides, a nationwide push for the metric system…

The year was 1878; the great inventor and scientist Thomas Edison was attempting to downsize electric lighting sources. He set out to redesign the way consumers would utilize electricity. Thomas Edison created small lightbulbs instead of the much bigger light fixtures that were in use during that time. He created small bulbs capable for indoor use, they were long-lasting, did not overheat, and above all could run on low power. A little over a year later, he patented the lightbulb using a strand…

There are many convieneces to solar power, but of course nothing is perfect. It is more convienet for the consumer because they will not have to purchase things to run their house or car, they could just have the solar pannels themselves and be independent. The one and major inconveience of solar power is what do you do on a cloudy day? Or if one place does not get a lot of sun how can it run? Advantages: Solar energy is a renewable resource that is environmentally friendly. Unlike fossil…

CHAPTER 1 INTRODUCTION In recent days, the increase in continuous power demand and very slow generation of power is making researchers to work more on efficient power generation. On the other side, the regular price hike in fuel, increase in global warming and adversely effecting environment pollution. Global warming is a good lesson for all of us, these challenges for engineers are encouraging them to work more on clean, renewable and eco-friendly sources. By using renewable energy…
