  • Waves striking a man-made jetty of rock. Caption: could help solve the world's energy problems.

    Harnessing energy from the waves of the world’s oceans seems like the ultimate in renewable fuel. With funding from the National Science Foundation, Electrical engineer Annette von Jouanne is leading efforts to capture wave energy, by creating simple, powerful devices that can withstand heavy winds, monster waves, and corrosive salt water. Oregon State University research now underway is based on ocean buoy generators. As ocean swells hit the buoy, electrical coils inside move through a magnetic field, inducing a voltage, and creating electricity.

  • Closeup of a huge pile of kernels of dried corn. Caption: making corn the number-one crop by weight.

    The evolution of the uses of corn coincides with some significant historical events. Throughout history, it has been a staple in the human diet, but in the 1950’s, it became the main ingredient in the meat industry. Farmers used corn to shrink the growth periods of cattle to meet the demand of the consumer. Corn syrup was born from the Cuban Embargo. Today, genetically engineered corn is seen in nonfood products.

  • Illustration of a windmill 100 meters tall receiving air current next to a much taller structure receiving a much larger air current. Caption: The beauty of wind turbines is that they're 100% clean.

    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.

  • Person pumping fuel into a vehicle. Caption: (narrator) And there you have it: synthetic diesel fuel.

    Typically, diesel fuel is made from crude oil, but scientists can make high-grade diesel from coal, natural gas, plants, or even agricultural waste, using a process called Fischer–Tropsch (FT). FT Diesel is the ideal liquid transportation fuel for automobiles, trucks, and jets. It’s much cleaner burning than conventional diesel, and much more energy-efficient than gasoline. But, FT Diesel is expensive to make and generates lots of waste. With support from the National Science Foundation and its Center for Enabling New Technologies through Catalysis (CENTC), chemists around the United States are working together to improve the cost and energy efficiency of alternative fuels.

  • Brightly colored tropical fish. Caption: how they work together to execute underwater maneuvers,

    With support from the National Science Foundation, aerospace engineer Michael Philen and his team at Virginia Tech are investigating the biomechanics of fish locomotion, in hopes of contributing to the next generation of robotic fish and underwater submersibles. They’re studying how fish use their muscles to swim efficiently and execute underwater maneuvers, such as darting around in perfectly synchronized schools. They’re also developing new smart materials, such as a bioengineered hair that is modeled after the hair cell sensors on the side of fish that allow it to detect minute changes in water flow.

  • Ceiling security camera footage showing store aisles. Caption: to track shoppers as they move in the store and create data

    Go into any grocery store and cameras may be watching you. These cameras are not looking for thieves, they’re looking for shoppers. The cameras are focused on the tops of peoples’ heads (so it’s anonymous), but they don’t have to see faces to track which store aisles get the most traffic and how long consumers spend looking over products. With support from the National Science Foundation, computer scientist and CEO of VideoMining Rajeev Sharma and his team have designed software that automatically generates statistics about in-store shopping behavior. These statistics can provide valuable insights for supporting critical decisions in store layout design, merchandising, marketing, and customer service. Sharma’s team has developed similar technology to help caregivers monitor the elderly.

  • Graphic of a mosquito overlaid on a map of Central and South America. Spanish captions.

    One of the areas that is most sensitive to climatic change is human health. Climate change affects human health in numerous ways. Some are immediate, and others may not manifest until future generations inhabit earth. Global areas have already begun to suffer the effects of ecosystem alterations and limited water sources. These situations also impact crop production and food distribution. Researchers also predict an increase in the number of displaced persons as the planet warms and sea levels begin to rise. Chapter 10 of Air: Climate Change Series.

  • Four soldiers in a desert. Caption: in Kevlar-like body armor.

    Kit Parker is a lieutenant colonel in the Army Reserve and has served multiple tours of duty in Afghanistan. Even when he’s not in uniform, this Harvard University bioengineer makes it his mission to protect the men and women of the U.S. armed forces. Parker and his team are developing next-generation nanofibers at the Harvard Materials Research Science and Engineering Center (MRSEC). The unlikely inspiration for Parker’s team is none other than the cotton candy machine. They use their own version of that technology to spin a wide range of polymers, both natural and synthetic, into new fabrics and materials for military use.

  • Cooling lava turning into stone. Caption: Kilauea is one of the longest currently-erupting volcanoes.

    Hawaii's Kilauea volcano is one of the best places on Earth to study processes within basaltic volcanoes. Its high eruption frequency, easy access to lavas, and distinct geologic setting far from plate boundaries or continents allow researchers to address fundamental problems related to active volcanoes. Another constant at Kilauea, besides the flowing lava, has been University of Hawaii geologist Mike Garcia. With support from the National Science Foundation, Garcia has been leading studies of Kilauea for a generation, adding to the extensive knowledge base on this volcano. Two of the primary goals are to determine what has triggered Kilauea’s effusive, explosive cycles over the last 2200 years and when long eruptions, such as the current one, will stop.

  • Earth as seen from space with the Sun visible behind it. Caption: (male narrator) All across the planet,

    Host award-winning geoscientist, Richard Alley provides an eye-opening look at some of the world's most important case studies in smart energy. Alley travels to Spain and Morocco where large-scale solar farms and individual photovoltaic panels atop tents in the Sahara are beginning to bring the vast potential of the sun down to Earth. In Brazil, abundant natural resources are transformed into efficient, sustainable biofuel, making Brazil the only nation whose cars could keep running if all gasoline were to vanish. In Denmark, and West Texas, citizens have taken sustainability into their own hands by becoming stakeholders in wind turbines. And in China, he explores multiple sustainable energy technologies, including exclusive footage from GreenGen, the world's most advanced low-carbon emissions power generation plant.

  • Person with a device attached to their head behind and above their ear and a wire leading to a device that is affixed to the back of their ear. Caption: It's called a cochlear implant, and it helps me hear.

    The cochlear implant is widely considered to be the most successful neural prosthetic on the market. The implant, which helps individuals who are deaf perceive sound, translates auditory information into electrical signals that go directly to the brain, bypassing cells that don't serve this function as they should because they are damaged. Led by engineer Pamela Bhatti at the Georgia Institute of Technology, a team of researchers at both Georgia Tech and the Georgia Regents University created a new type of interface between the device and the brain that could dramatically improve the sound quality of the next generation of implants.
