Chapter 6 Internet Research Topic and News Article Choose one of the Internet Research topics for Chapter 6 and answer it with a short essay then read and summarize a current physics or technology news article Part A How long are the longest power transmission lines Are people considering making them even longer Why Why not just put the source of power where it is most needed for example near cities A power line is a cable that carries electrical power from power plants and distributes it across large distances The power is transmitted through a transmission grid which is a network of power lines and stations It is then distributed to one of the three main grids in the United States and from there will flow to throughout them and distribute power The worlds longest power is the Rio Madeira transmission line located in Brazil and it is 2 385 km long Most long distance transmission electricity uses high voltage When using high voltage lines you are able to cut down the amps used which leads to the less amount of power you lose from heating Power transmission lines are being considered to be made even longer thanks to renewable energy Because of the rapid growth of solar and power there are plans to not only expand power transmission lines but to make them more energy effecting as well Renewable energy is the way of the future and the hope for many is to be able to transport electricity taken from solar and wind power through the power lines The length and capacity of power lines are expected to triple by the year 2050 Some locations are not set up to have a power plant there which is why a power transmission line delivers power to that city from another power plant The power lines are intricately working to transfer power from on place to another the answer can not simply be lets build another power and power lines when a system is already in place Because these power lines that are transporting energy are so interwoven one little addition would mess the whole grid system up It is simply easier to build more power lines to transport energy even farter or wherever it needed to be Part B Find and read an article on physics or technology from some serious website Give the link to the article and summarize the article drawing connections to class and or explaining what you do not understand about the article Streetlights are soon to be a thing of the past in one city in China It is planned by the year 2020 a moon would orbit Chengdu a Chinese city lighting up its sky at night This moon would actually be an illumination satellite that would orbit 300 miles above the city and reflect the sun back down to eat to light up the sky at night This satellite is planned to shine 8 times brighter than the actual moon The goal of this project is to cut down on the cost of using streetlights in the busy cities of China There are some other benefits that would come from this project like being able to assist in times of crises like power loss to shine light on the affected area Another advantage to this type of moon is that it is human controlled meaning we can increase or decrease its brightness or even shut it completely off if needed Even though this project has been try in Russia before and failed this project is hoping to be successful with only some minor snags along the way One thing I do question about this is I wonder what they improved on about this illumination satellite because another one that was made failed during the launch process I am very curious to see how successful this project is because if it is a huge high that is saving so much money I wonder if it is something the United States would consider doing Part A Hill Joshua S Rapid Electrification Together With Wind Solar Will Drive Massive Grid Expansion CleanTechnica Sustainable Enterprises Media Inc 14 Sept 2018 cleantechnica com 2018 09 14 rapid electrification together with wind solar will drivemassive grid expansion Part B Jorgeson Amber Forget Streetlights China Is Launching Artificial Moons in Urban Areas Discover Kalmbach Media 22 Oct 2018 blogs discovermagazine com dbrief 2018 10 22 fchina is launching artificial moons W9C47ZNKgU0
