Wind is a natural resource that is readily available and virtually everywhere. Humans have been harnessing the power of the wind for around 2,000 years. The Dutch made the windmill famous. Defines the process of turning the kinetic energy of the wind into electrical energy. Shows how the large wind turbines are built using a simplistic design and modern technology. Explores how the use of wind power is growing and becoming widely used throughout the world.
Kathryn Johnson, an electrical engineer at the Colorado School of Mines, studies large utility-scale wind turbines. Kathryn’s research aims to make the turbines more efficient in order to capture as much of the wind’s energy as possible. Viewers also visit NSF’s National Center for Atmospheric Research, where scientists are working with local utility companies to create an advanced wind energy prediction system. Using data from sensors mounted on each turbine, the system generates a forecast specific to each turbine on a wind farm. This helps the utility company provide as much energy as possible from clean sources.
Part of a series that features a wide variety of video footage, photographs, diagrams and colorful, animated graphics and labels. For this particular video, students will focus on how wind turbines convert kinetic energy from the wind into mechanical and electrical energy. Part of the Science Video Vocab series.
A Category 5 hurricane is a monster of a storm that most people would want to avoid. But, Civil Engineer Arindam Chowdhury actually recreates those monster hurricane force winds in hopes of helping people better prepare for the real thing. With support from the National Science Foundation, Chowdhury and his team at Florida International University and the International Hurricane Research Center designed a 15 foot tall Wall of Wind (WOW). The goal is to see if low rise structures and building materials can withstand the same wind forces they would face in a full-blown hurricane.

Wyoming has long been known as an energy exporter, from oil to natural gas to coal. The state is now booming with two other resources: wind energy and qualified technicians trained to build, install, and service the growth in wind turbine technology. With National Science Foundation funding, Laramie County Community College in Wyoming is becoming a national leader in training.
Here's a riddle: What can you hear and feel, but not see or hold? The wind, of course! Investigate the mystery of wind: what it is, where it comes from, how we use it, and how it shapes our lives and the world around us. Learn about good versus destructive winds, and check your knowledge with a review.
Can the wind provide us with all of our power? Along with cutting-edge wind farms and new turbine designs, this production meets renegade inventor Doug Selsam as he builds the world's first flying turbine, a device that may just change our world.
A cure for Motherboard might be hidden in the windiest spot in the Northern Frontier, and the kids must figure out how to measure wind speed to find the cure. Part of the "Cyberchase" series.
From cyclists to race cars, the motion of an object is determined by the sum of the forces acting on it. An aeronautics engineer works with Newton's three laws of motion to test the best bicycle posture and helmet in a wind tunnel.
Moko is an explorer. As he travels the world continent by continent, he makes many friends and discovers many natural phenomena which sometimes delight him, and other times scare him. Each animated episode recounts an adventure and takes an "original story" approach to explaining these natural phenomena. In this episode, Moko thinks that somewhere lies a creature that blows so hard that it makes the boughs of trees quiver and creates the desert dunes. He believes that the clouds flee before the wind comes because they are afraid of the creature. He decides to go look for it. Tired after walking beneath the hot sun, a fresh, light breeze makes his rest more pleasant. However, the creature is actually the Harmattan blowing over West Africa.
For millennia, hurricanes have threatened the Eastern United States, the Caribbean, and parts of Latin America. But changes to global climate have serious consequences for the future. For example, rising sea-levels mean that storm surge from hurricanes will impact ever further inland. In episode three, specialists discuss why they believe that hurricanes will become less frequent but increasingly powerful. Insight and interviews from leading experts such as Nobel Prize-winning climatologist, Jean-Pascal Van Ypersele, explore the preparations needed to withstand a super storm. Part of the "Hurricane, the Anatomy" series.
Eco, the little bear, travels around the world observing human interactions with the environment. During his journey, he meets many other friends from the animal kingdom and gets a firsthand look into some of the environmental and social problems facing the planet. Eco and his friends provide ways for humans to ensure a healthy planet for the future. Part of "Eco S.O.S." series.
Moko is an explorer. As he travels the world continent by continent, he makes many friends and discovers many natural phenomena which sometimes delight him, and other times scare him. Each animated episode recounts an adventure and takes an "original story" approach to explaining these natural phenomena. In this episode. Moko and Totemie take a boat and travel across the lake to where the landscape is very different. Suddenly, they see a strange column twirling in the horizon. The wind is getting stronger and stronger all around them. Moko and Totemie find a tree and hang on to it as tightly as they can. The cyclone goes over their heads and they can see in the center of the column of wind. Moko thinks that if you respect the power of nature, then nature lets you see some of its secrets.
With support from the National Science Foundation (NSF), Forrest Masters and a team at the University of Florida are developing new technologies to help engineers and scientists better understand the strong, high-wind storms that batter communities along U.S. coastlines. The National Home Education Research Institute (NHERI) has the broad goal of supporting research that will improve the resilience and sustainability of civil infrastructure against the natural hazards of earthquakes and windstorms. Part of the "Science Nation" series.
Gives a general introduction to microscopes, a device invented 400 years ago. Begins with a simple magnifying glass and moves to the optical, confocal, electron, scanning electron, and the scanning tunneling microscopes. Shows that each one "sees" with increasing detail. The microscope opens invisible worlds and aids scientists in improving ours.
In this episode, Mo Rocca explores how teen inventors are out to stop distracted driving, and learns how Thomas Edison’s inventions are still making us look all look like slackers. Then, he explores the invasion of the drones and windmills the size of fleas that have the potential to revolutionize electric power.
The connections between neurons in the brain are involved in everything humans do, and no one’s pattern is the same. Imagine the medical breakthroughs if doctors understood more about the brain’s circuitry. With support from the National Science Foundation, neuroscientist and psychiatrist Karl Deisseroth and his multidisciplinary team at Stanford University have developed a new imaging technology that essentially makes the brain transparent. They can then generate detailed 3-D images that highlight specific neuronal networks. Deisseroth has named this process “CLARITY.” Part of the National Science Foundation Series “Science Nation.”
Demonstrates techniques for using a student microscope to achieve spectacular images. Emphasizes correct lighting procedures and the techniques required for viewing living cells.
Moko is an explorer. As he travels the world continent by continent, he makes many friends and discovers many natural phenomena which sometimes delight him, and other times scare him. Each animated episode recounts an adventure and takes an "original story" approach to explaining these natural phenomena. In this episode, on that night the tide was low and the boat had been beached. Moko and Alarick were playing percussion and flute to pass the time. Suddenly, it was as if their music was being accompanied by a strange singing. They decided to investigate the source of this strange new sound. Walking along a hilly path in the forest, they were surrounded by hundreds of tall rocks that stood like humans in the dusk. A gust of wind blew and they could once again hear the bizarre song. Frightened at first, Moko and Alarick decided that the rocks were singing as a choir and the joined them with their instruments. When the wind fell, they regained their boat, happy to have participated in the symphony of the singing stones who were probably lonely and wanted to attract visitors.
