Follow the history of hydroelectric energy and explore the process of turning the down flow of water into usable energy. Shows the function of the turbine and water level at the hydroelectric dam, as well as the scale of a dam construction.
The rapid population growth in large urban centers of the world has made it necessary to look for alternatives to development in order to make cities suitable for living. PROSPECTA, an international event, aims to promote ideas of change by thinking about society's future, starting with proper planning and development.
Structural engineers at the University of California, Los Angeles are hoping to design earthquake-resistance buildings and communities. They are using data and computer modeling to design structures able to withstand major earthquake events. These models are meant to guide safety inspections following earthquakes and help engineers locate “hotspots” more quickly. Part of the “Science Nation” series.
Steam power and the Industrial Revolution led us into our modern age. Now, society relies on electricity to power our lives. Architects have built skyscrapers and invented the elevator and escalator to help navigate the height of these structures. They have also built up, around, and underneath natural barriers, even reclaiming land from the sea in the Netherlands with a series of dams and flood control.
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.
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.
