In this episode, the Standard Deviants tackle thermodynamics. The study of thermodynamics involves the conversion of energy to useful forms of power. They discuss the three laws of thermodynamics, heat engines, work processes, heat sources, and entropy. Part of the "Standard Deviants School: Physics" series.
Thermodynamics deals broadly with the conservation and conversion of various forms of energy. It also describes the relationships between energy and the changes in properties of matter. Other topics covered include Hess's law, the laws of thermodynamics, and the Gibbs free energy. Part of the "Chemistry" series.
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).
Teaches caveman Zog that people use energy in one of two main ways: by moving heat from one place to another (conduction, convection, or radiation) or by transferring energy from one form to another by using an appliance, like a lamp or car. Appliances always waste some energy, and Zog learns why energy efficient appliances are the best choices people have today. As only a caveman can, Zog provides plenty of laughs along the way to finding clever and complete answers to elementary energy questions.
Using a balanced chemical equation to calculate amounts of reactants and products is called stoichiometry. It is a super technical-sounding word that simply means using ratios from the balanced equation. Topics covered in this program include the metric system, balancing equations, molar conversions, mass percent, empirical formulas, and limiting reactants. Part of the "Chemistry" series.
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.
There’s a new renewable energy player in town, and it’s about to make waves in the industry. Despite its massive potential as a source for renewable energy, the ocean is unlikely to contribute meaningfully to electricity supplies without dramatic, innovation-driven reductions in the cost of energy conversion. That’s where engineers Balky Nair, Rahul Shendure, and Tim Mundon come in with their company, Oscilla Power. With support from the National Science Foundation, they’re developing a utility-scale wave energy harvester called the Triton. This technology shows promise as a means for delivering utility-scale electric power to the grid at a price that is competitive with conventional fossil or renewable technologies. Part of the National Science Foundation Series “Science Nation.”
