Solar Power – An Alternative Energy Source
Part of the Series: Show Me Science Series - Advanced
Alternative energy sources are being researched and developed to improve efficiency and reduce costs. Fluctuating costs of oil, coal and natural gas, along with their possible negative effects on the environment, has made energy sources such as wind and solar…
Energy – Understanding Hydroelectric Power
Part of the Series: Show Me Science Series - Advanced
Water constantly moves through an immense global cycle, evaporating from lakes and oceans all over the world, condensing to form clouds, precipitating as rain and snow, which then flows back to the oceans. Hydroelectric power takes advantage of this water…
Gas Turbines – Energy Powerhouses
Part of the Series: Show Me Science Series - Advanced
In a gas turbine, the linear motion of gas causes rotors to spin, ultimately creating electricity. The forward rotating blades pump air under high pressure into the combustion chamber where natural gas ignites on contact with the air. At 1,500…
Wind Power - A Renewable Energy Source
Part of the Series: Show Me Science Series - Advanced
This program explores wind power's alternative energy production in today's oil-dependent economy - how it works and the environmental factors that scientists are researching.
Energy - Biofuels Use on the Rise
Part of the Series: Show Me Science Series - Advanced
The energy demands and rising cost of oil have encouraged scientists and engineers to develop renewable energy alternatives. Biofuels are renewable energy sources from organic materials such as plants or animals that are directly converted into liquid fuels. The two…
Thin Ice - The Inside Story of Climate Science
In recent years climate science has come under increasing attack, so concerned geologist Simon Lamb grabbed his camera and set out to explore the inside story of climate research. For over three years he followed scientists from a wide range…

Propulsion – Technological Advances
Part of the Series: Show Me Science Series - Advanced
The invention of the solid fuel propulsion system combined with Newton's Third Law is the simplistic basis for modern rocketry. This program reviews the history of propulsion and explores its use as a viable energy source of the future.
Fuel Technology - Transportation Innovations
Part of the Series: Show Me Science Series - Advanced
The automobile industry is going through revolutionary changes. The standard petroleum gasoline fueled engine has some new competition from gas-electric hybrids, electric vehicles, hydrogen fuel cell vehicles, natural gas vehicles and even some automobiles that get some of their power…
Energy: Transforming Renewable Resources – Biomass & Solar Energy
Part of the Series: Show Me Science Series - Advanced
This program stresses the importance of caring for our environment and provides an overview of multiple energy sources such as biomass and solar energy. It documents how some states are trying to enact laws that require local power plants to…
