Chemistry is the science of interacting particles and the various states of matter. Developing a better understanding of the atomic model through experiments with gases, scientists discovered the Ideal Gas Law, developed phase diagrams, and learned about the properties of supercritical fluids. Today's chemists are exploring new ways to control the interactions of atoms, with the goal of making better hydrogen-powered cars and new technologies for the long-term, underground storage of carbon dioxide to reduce greenhouse warming. Part of the series Chemistry: Challenges And Solutions.

Part of the "A 3-D Demonstration" series. Defines electric power and explores in general terms a variety of means by which it is produced, transmitted, and consumed. Discusses energy conservation in relation to power production, transmission, and consumption with a particular focus on the efficiencies and inefficiencies associated with the conversion of electricity to light. Specific modules include Efficiency I: Power Production, Power, Efficiency II: Power Transport, Power Transmission, Power Consumption, Inefficiency I: The Light Bulb, and Inefficiency II: The Fluorescent Bulb. Correlates to all National CTE Organizational Standards (including the provisions of the Perkins Act).
Environmental and science experts explore the enormous potential for clean, renewable energy. They also illustrate the connections among such issues as solar energy, wind energy, energy efficiency, green buildings, and global climate change. Viewers also learn specific action steps that viewers can take in their own lives to create a sustainable future.
Solar power is defined as the energy produced by converting sunlight into heat or electricity. It is one of the most abundant and affordable sources of energy available. However, it is difficult to harness (and even impractical) in some parts of the world, so it is important to explore the process of converting sunlight to power. Shows three primary ways to produce solar power on a large scale: solar power–generating plants, photovoltaic cells, and solar thermal heaters.
Host Lisa Van Pay meets with NSF-funded scientists Yang-Shao Horn and Yogi Surendranath at the Massachusetts Institute of Technology as they take on the hydrogen energy challenge.
Officer Tom McCloghry is a cop on the beat, patrolling downtown Columbia, South Carolina to keep the streets safe. And, though it's not so unusual these days to see police on Segways, this one is different. This is a hydrogen hybrid Segway, created with support from the National Science Foundation.
What is the best way to power the planet? Travel the globe with scholar Johan Norberg, from Morocco to Sweden and throughout the United States, as he explores the pros and cons of the eight main energy sources available to us: coal, oil, natural gas, nuclear, hydro, biomass, wind, and solar.
Fruits and vegetables are filled with a host of health-promoting benefits, but often times individuals fall short on their daily servings. Join food and health professionals as they discuss the power and health benefits of fruits and vegetables.
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.
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.
Part of the animated "Johan, the Young Scientist" series. While waiting for his rechargeable batteries to charge up, Johan discovers in ScienScape that electricity is generated by cranking up a dynamo. Professor Hoo then sends him, Ani, and Moki to find how different power stations use different methods of generating electricity.
Join Dr. Knowledge as he takes young viewers on a fast-paced adventure to learn about energy and electricity. Shows what tools, appliances, factories, and everything from iPods to airplanes have in common. Each needs energy to do their jobs. But, where does that energy come from? We know we can get our power from a wall outlet, but that's only the beginning. Dr. K and the Inquisitive Minds team trace the electricity from the wall through the power grid to its source.
Part of the "Green Careers" series. Details the entire range of jobs needed to make solar power a reality from research and development, design and marketing, and financial analysis to construction and project management. Engineers, analysts, and managers share how they work in this emerging green industry and how they found the opportunity to be part of the clean energy solution. Jobs profiled include the following: research and development engineer, design engineer, marketing manager, financial analyst, construction manager, and project manager.
Stuart Rowan, a professor at Case Western Reserve University, has created polymers that are able to self-heal when heat is applied using a special light. Part of the Fast Draw Series.
Arizona gets plenty of sunlight, and researchers there are working hard to turn that energy into electricity. At Arizona State University, graduate student Brad Brennan makes and tests new materials that will allow industry to build smaller, cheaper, flexible photovoltaic solar cells that can go almost anywhere.
Revolutionary technologies now make it possible to harness a completely renewable energy resource-the natural power of the sea. Explores ways that electric power can be drawn from tidal forces or from fluctuations in ocean currents. Highlights several innovations, including a tide-driven rotor off the coast of Cornwall in the United Kingdom, a multi-rotor locks system in the English Channel, an OTEC (i.e., ocean-thermal energy conversion plant) in southern Japan, and another OTEC facility in Hawaii. Commentary from the inventors, designers, and managers of these systems is included along with animation that illustrates how each mechanism works.
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.
