Hydroelectric Power

Hydropower has already made a huge impact on the world today. “Hydropower is the largest source of renewable energy in the entire world, producing around 16% of the world’s electricity from over 1 200 GW of installed capacity”. In other words hydroelectric power provides almost one-fifth of the world's electricity. Canada, China, Brazil, Russia and the United States were the five largest hydroelectric power producers in 2004. The biggest hydro plant in the U.S. is located at the Grand Coulee on the Columbia River in northern Washington. One of the biggest hydroelectric dams in the world is located in China at the Three Gorges on the Yangtze river, this dam is 1.4 miles wide and 607 feet tall. Hydropower is expected to remain the largest source of renewable electricity generation by 2023. Hydropower is a very mature technology, but it continues to evolve everyday. Hydropower can also be a very good source of electricity because it costs less than most energy sources. “In fact, all but two states (Delaware and Mississippi) use hydropower for electricity, some more than others. For example, about 74 percent of Washington State’s electricity comes from hydropower”.

As you already know hydropower has been used for thousands of years. It had developed so much since it was first used by the Ancient Greeks. People may think that hydropower can only advance so far, but that is not true at all. Hydroelectric power will keep advancing for years even centuries. Scientists can learn how to make it less expensive, more efficient, make the dams smaller but still have them produce just as much electricity or even more! Everyday engineers, scientists etc will be developing new ways to make hydropower more efficient than it is today. Hydropower will never stop advancing, at least not before I pass away.
Several countries use water or hydropower to power there everyday ordinary lives. Hydropower was first used thousands of years ago by the Ancient Greeks. The Greeks used it to grind large amounts of grain, but hydropower has had several technological advances since then. Hydropower is now used to power homes, buildings, construction sites, factories etc. Humans have been using and taking advantage of hydroelectric power for centuries now. Hydroelectric power is made and stored in a huge damn, generally across large water systems such as rivers. The electricity is then transported through long distance electric lines.

Force and Motion in Concerts

Force and Motion Blog  By Amadi Clemens INTRODUCTION: Do you listen to Travis Scott? If so, you know of his most recent album AstroWorld has been on tour. One of his recent shows (in Oakland, California) he performed with a roller coaster. Crazy, right? It wasn’t like a full roller coaster that you see Six Flags. It’s like the Ring of Fire at Clementon Park. His ring ties into his theme park theme! PROS AND CONS: There are pros and cons that follow this event. A pro is that it was a fresh idea. I’ve seen amusement parks and rides in music videos but never live in concert. Another pro is that it was eye-catching and entertaining.. The main idea of a concert is that it is entertaining, this is going back to the idea of fresh. A con is that it’s very dangerous. Although thrilling, what if something goes wrong? What if it breaks? What if it stops mid-way in the year and he can’t rap anymore? Mechanical service would have to come and get him and that can ruin the concert. Another con, ...

Chemical complexities that causes Saturn's rings to change planet’s atmosphere

Ayad Alhazmi 10/19/2018 Chemical complexities that causes Saturn's rings to change planet’s atmosphere New discoveries are made today on Saturn's rings by the Cassini space probe. Based on data from the final orbits of NASA's Cassini space probe shows the rings of Saturn. Some of the most amazing celestial objects in the universe are far more chemically complicated than was previously understood by scientist. When the Cassini space probe first gathered the information from 2017 and the signals of Cassini took scientist a long time to retrieve the information. Also knowing the astrophysicists are still studying it is beyond my reach. I will show you a quote by a professor of physics and astronomy Thomas Cravens. "Two things surprised me. One is the chemical complexity of what was coming off the rings -- we thought it would be almost entirely water based on what we saw in the past. The second thing is the sheer quantity of it -- a lot more than we originally expected. ...

The Earth is a very big Magnet Its North and South Poles are Highly Magnetic

The Earth is a very big Magnet     Its North and South Poles are Highly Magnetic   By: Alzahraa Alrubaiey Magnetism is the force exerted by magnets when they attract or repel each other. Magnetism is caused by the motion of electric charges. Earth has two geographic poles: the North Pole and the South Pole. They are the places on Earth's surface that Earth's imaginary spin axis passes through. Our planet also has two magnetic poles: the North Magnetic Pole and the South Magnetic Pole. The magnetic poles are near, but not quite in the same place as the geographic poles.   The Earth is a magnet that can interact with other magnets in this way, so the north end of a compass magnet is drawn to align with the Earth's magnetic field. Because the Earth's magnetic North Pole attracts the north ends of other magnets, it is technically the South Pole of our planet's magnetic field. A compass point north because all magnets have two poles, a north pole...
