The Solar System The majority of the solar system is made up of the sun and all of the planets that orbit it. There are also moons‚ comets‚ asteroids‚ dust‚ gas‚ and dwarf planets. The sun makes up about 98 percent of our solar system. Because of the suns large mas it pulls every thing in the solar system towards it. The planets orbit around the sun because of the sun pulling it towards it and the planets trying to fly outer space at the same time‚ which balances it out. It was once believed that

Argumentative Essay About Internet Censorship Censorship has been defined as “The removal of material that is deemed or judged offensive to any sector of the population. Many have wondered‚ “Just how beneficial is censorship to man‚ when is it enough and does it help”? It is my view however; that there is no clear answer to the question‚ for censorship has its fair balance of advantages and disadvantages. I argue that the censorship of the internet in the modern digital era is “Ludacris” ridiculous

Characteristics A solar panel is a collection of many small solar cells spread over a large area. These solar cells work together to provide sufficient energy to power a given item. (Northwestern University) Their creation is a very delicate process which is why many of their advancements did not come until last quarter of the 20th century. In this period‚ advancements in semiconductors and photovoltaic products allowed efficient and cost effective solar panels to be produced. (Solar Panel Info)

A solar cell (also called photovoltaic cell or photoelectric cell) is a solid state electrical device that converts the energy of light directly into electricity by the photovoltaic effect. Assemblies of cells used to make solar modules which are used to capture energy from sunlight‚ are known as solar panels. The energy generated from these solar modules‚ referred to as solar power‚ is an example of solar energy. Photovoltaics is the field of technology and research related to the practical

Solar Roadways 2. Contents Introduction Theory Structure Advantages Disadvantages References 3. Introduction The Solar Roadways consists of structurally engineered solar panels that we drive on. Each Solar Road Panel (roughly 12’ by 12’) interlinks with neighboring panels to form the Solar Roadways system. The Solar Roadway generates electrical power from the sun and becomes a nation’s decentralized‚ intelligent‚ self-healing power grid‚ replacing our current deteriorating power distribution
