  • Gently arching bridge over a large body of water. Caption: but the Skye Bridge spans the equivalent distance

    Engineers and architects are creating bridges that combine the best of both art and design. Bridges are no longer just a tool to get from one side of the river to the other. Some bridges have the goal of being aesthetically pleasing and efficient for pedestrians. Others rely on the cantilever design to span a distance equivalent to three and a half jumbo jets. Bridges are often classified by their structure and how the forces of tension, compression, bending, torsion and shear are distributed. Shows how designs vary depending on the function of the bridge, the environmental factors, the materials, and technology used to construct them.

  • An old car from the 1920's driving next to contemporary cars. Caption: The very first cars were powered by electricity.

    For centuries, land travel was restricted to how fast and far humans or animals could walk. In the 19th century, the invention of the bicycle transferred human energy to a set of wheels. During the Industrial Revolution, the invention of the steam engine led to the railroad, a change in transportation that created the tourist industry. In the early 20th century, the invention of the automobile forever changed how humans travel, and with the assembly line, Henry Ford forever changed how goods are manufactured.

  • A large bank of solar panels. Photovoltaic cells. Caption: Or on a smaller scale by using photovoltaic cells.

    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.

  • Illustration of a windmill. Caption: which spins a generator to create electricity.

    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.

  • Illustration of a measurement device attached to leads which surround a central core that is emitting a moving magnetic field. Caption: As long as the magnetic field moves

    Part of the "A 3-D Demonstration" series. Looks at physics principles behind AC and DC generators. Examines the relationship between a changing magnetic field and the induction of electric current. A hand rule is introduced to predict the generator effect in a linear length of conductor exposed to a changing magnetic field. The behavior of a rotating coil in a magnetic field leads to the practical construction of an AC motor. Introduces split-ring commutator generators, as well as the more common alternator as a means of generating DC electricity. Specific modules include Generating Electricity, Inductors, Generator Left-Hand Rule, Generator Electromotive Rule, AC Generators, and DC Generators. Correlates to all National CTE Organizational Standards (including the provisions of the Perkins Act).

  • 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.

The researchers hope that architects will someday use their model to make building designs even greener.
