“Solar Treated Purification” Intorduction: A. Background of the study: In our world today‚ purified water is the one that most of the people drink everyday especially those who live in cities. Water purification is the process of removing undesirable chemicals‚ biological contaminants‚ suspended solids and gases from contaminated water. The goal is to produce water fit for a specific purpose. Most water is purified for human consumption (drinking water)‚ but water purification may also be designed

A solar inverter‚ or PV inverter‚ converts the variable direct current (DC) output of a photovoltaic (PV) solar panel into a utility frequencyalternating current (AC) that can be fed into a commercial electrical grid or used by a local‚ off-grid electrical network. It is a critical component in a photovoltaic system‚ allowing the use of ordinary commercial appliances. Solar inverters have special functions adapted for use with photovoltaic arrays‚ including maximum power point tracking and anti-islanding protection

Outline: Reusable Water Bottles I. Introduction A. 50 billion plastic water bottles end up in the U.S. landfills each year. That’s 140 million every day! That is enough‚ laid end to end‚ to reach China and back each day. (“Tap water vs bottled water..”) B. According to our class survey‚ more than half of the class buys water bottles more frequently than others. C. I‚ myself‚ use to buy bottled water almost everyday‚ at school‚ work and the gym. II.

money in the water bottle industry‚ but compared to the price paid on producing and selling bottled water‚ it is a very small amount. Bottled water is not only costly to us‚ but also to the environment. Bottled water is preventing our world from going green by negatively damaging our environment‚ hurting the economy‚ and harming human lives’. Bottled water negatively affects the environment in many ways. “Of the 36 billion bottles sold in 2006‚ only one-fifth of the bottles were recycled.” This

DC Circuits: Electric Power PHY 114 Lab Report 10/09/2013 Abstract: The purpose of this experiment was to look at electric power dissipated in a load resistor in a circuit with a real power source‚ which has a finite internal resistance. We discover a surprising result about how to deliver the most power to a device from a source. Consider a simple circuit in which a battery of voltage drives a current through a resistor of resistance. As we have seen‚ the battery is continuously doing

The researchers were able to gather information from different journals and newspapers that already featured the solar panel. Moreover‚ they indicate information that was gathered from the internet. This study used descriptive method of research because the researchers aim to elaborate all the features of solar panel. The study was designed to give knowledge on the use of solar panel

1880‚ Thomas Alva Edison invented the incandescent light bulb and patented it. It’s an invention that has been around since the 1800’s. This invention has significantly‚ affected society by allowing the world to create a comfortable safe environment. Edison had come up with a 16-watt bulb that lasted for over 1‚500 hours. Edison’s light bulb needed improvements‚ and those improvements are the reason we have light bulbs today. The light bulb was invented by using a low current electricity‚ a small

16 June 1976 Student Uprising in Soweto When high-school students in Soweto started protesting for better education on 16 June 1976‚ police responded with teargas and live bullets. It is commemorated today by a South African national holiday‚ Youth day‚ which honors all the young people who lost their lives in the struggle against Apartheid and Bantu Education. In 1953 the Apartheid Government enacted The Bantu Education Act‚ which established a Black Education Department in the Department of
