Host Lisa Van Pay visits the scientists and engineers working to make the electric car of the future a reality today. One of the toughest parts is storing enough potential energy in the battery. Graduate student Katharine Stroukoff from the University of Texas-Austin explains how her research may help build a better battery, while Mike Nawrot and Dan Lauber, members of the MIT electric vehicle team, describe the advantages of their fully electric Porsche 914.

With today's high fuel costs, it is time to start looking beyond petroleum and into renewable resources to power vehicles. Ethanol is a clean-burning fuel derived from plants, primarily corn. It is combined with gasoline to produce a cleaner fuel that doesn't emit as many greenhouse gases as pure gasoline. Pure ethanol has not yet been approved to fuel vehicles, but it is the fuel of choice for racecars. By mixing gasoline with ethanol, fuel supply can be extended. Explores the production of ethanol and highlights the importance it holds in the "green power" movement.
Staying safe in all kinds of weather and avoiding weather-related injuries are the focus of this practical video. Concepts and terminology: lightning, tornado, wind, hurricane, and safe shelter.
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.
The project is called VORTEX2. For five weeks in the spring of 2009, and again in spring 2010, 100 researchers and scientists from 16 universities deployed about 40 vehicles armed with high tech equipment to measure and probe tornadoes and tornado development.
In this episode, host Joe Hanson and YouTuber Molly Burke, who is blind, discuss echolocation. They work through a series of active echolocation exercises to help the brain construct images of their environment. Part of the "It's Okay to Be Smart" series.
Speed, elegance, comfort, and many other factors are taken into account when creating a car. Car designers must be intentional in the creation of a great vehicle and ensure that all parts work together. Sports cars must have powerful engines, excellent chassis, strong suspension systems, and fuel efficient systems. Automotive technology ensures that consumers get more than just a pretty car.
Ever wonder where millions of retired vehicles end up? An old jalopy begins a fascinating journey towards a new incarnation of steel. Watch as a car gets crushed, shredded, melted, and transformed. Learn how its components change form with the addition of energy. Part of the "Break It Down" series.
University of Colorado engineer Abby Watrous is on a mission in rural China, converting coal-burning homes and cook stoves into cleaner-burning models. With funding from the National Science Foundation, this civil and environmental engineer is helping to develop renewable energy technologies in developing communities. Watrous and her colleagues are looking at ways to help more people use biomass.
Host Jeff Corwin races to the west coast to uncover the secrets behind a marine mammal disaster. Thousands of weak sea lion pups have been stranded along beaches throughout Southern California. Jeff is on a mission of research, rescue, and recovery.
Host Jessica Robertson travels across North and South Carolina to gather questions about climate change. Scientists from the United States Geological Survey (USGS) provide the answers and information on how to learn more about climate change.
Provides an overview of how Newton's three laws of motion can be used to explain and predict the motion of everyday objects. The effect of friction, including air resistance, is highlighted, and the concept of inertia is illustrated with classic demonstrations. Features questions for class discussion, as well as the remarkable Rocketman, who provides a dramatic example of the third law in action.
Aeronautics is the science of flight as well as the theory and practice of aircraft navigation. Any machine that flies through the air falls into the field of aeronautics. This includes helicopters, airplanes, as well as space vehicles such as the SpaceX Dragon and the retired NASA space shuttles. Aerodynamics is a branch of physical science which deals with the motion of air and the way that it interacts with objects in motion.
A group of leading engineers in unmanned aerial vehicles (UAV) gathers on the USS Midway to discuss careers in technology fields. Mike Atwood and Darren Moe of General Atomics describe how their company aids the military, and George Guerre of Northrop Grumman discusses how drones survey various weather conditions. Mike Veale of San Diego Zoo Safari Park explains how drones help stop the poaching of rhinos and elephants in Africa. Part of the “STEAM Leadership” series.
Learning to incorporate a variety of eco-friendly energy sources into businesses and homes will make Earth a better place to live. Students explore photovoltaics, the design behind wind turbine technology and the creative processes behind vehicles in the American Solar Car Race. Zero energy houses of the future will use many of these technologies to produce more energy than they consume. Renewable energy technologies are important for the future of our planet.
Currently, cities have a fundamental role in the struggle against climate change and harmful environmental practices. But, at the same time, major global cities consume more than two thirds of the world’s energy and release seventy percent of the global emissions of carbon dioxide. Climate change has become part of the worldwide agenda for major cities as they develop policies and practices to protect the environment and reduce greenhouse gas emissions. Chapter 2 of Air: Climate Change Series.
For nearly a decade, with support from the National Science Foundation, Doppler on Wheels (DOW) has been doing its best work in dangerous weather to gather scientific data about wind, rain, and snow. Meteorologist Josh Wurman and his team at the Center for Severe Weather Research in Boulder, Colorado coordinate a fleet of storm-chasing vehicles from a compact control room inside one of the DOW trucks. From thunderstorms to blizzards, hurricanes to tornadoes, DOW is providing extensive and detailed information that may ultimately improve warning systems and weather prediction. Part of the National Science Foundation Series “Science Nation.”
The 1960s world population has nearly doubled and now tops 7 billion. Population growth, though little discussed, is putting an unprecedented burden on the planet's life systems. Brings to light the connection between overpopulation and our most pressing environmental and humanitarian problems, as well as the solutions. Also, follows Beth, an American mother and child rights advocate, who grew up in a large family of 12 as she travels to Africa to witness first-hand the impact of population growth in the developing world and its role in exacerbating poverty. While there, she meets a young Ethiopian woman, Zinet, who comes from a poor family of 12, but has found the courage to break free from long-held cultural barriers holding back women. Features a broader discussion of the solutions to overpopulation in both the developed and developing world.
With the retirement of NASAs space shuttle fleet in 2011, the role of getting people, satellites and other instruments into space falls to private companies. As of June 2011, there have been only 523 people to reach the 100 kilometer mark (considered human spaceflight), and only 24 have traveled beyond low Earth orbit. It is projected that within ten years, the number of people who will have flown into space will increase by about 600 percent due to the increasing market of suborbital spaceflight and the possibility of private citizens utilizing space flight. Students will explore suborbital and orbital spaceflight and the requirements necessary for vehicles to achieve these journeys. They also go behind the scenes of many of the private companies involved in taking on the tasks to travel to low Earth orbit and beyond and uncover some of the technology used to accomplish these goals.
