Can people in remote rural areas who are far from electric generating plants get power for their lights and appliances? Solar cells make it possible. Mechanical and electrical engineers at the US Department of Energy's Sandia National Laboratories take viewers through the process of designing and installing solar cell panels in remote locations.
How does the Earth travel around the sun? Here the scientists will create a sundial to find out. The scientists will also explain how a remote control works. Part of the House of Science Series.
Looks at nerve signals and how they are transmitted. Provides an overview of nerve messages in reflex activities at both the chemical and electrical levels as well as the activities of networks of nerve cells in contact. NOTE: Contains some nudity.
Graphene could make it possible for electricity to move effortlessly through computer chips, thereby allowing computer systems to run faster than ever before. Savings in both heat and energy costs could have graphene replacing silicon as the basis of computer chip construction. Part of the Fast Draw Series.
Hans, Ruby, and Mho are trying to make a circuit but are finding it hard to keep it all together. Have no fear, printed circuit boards (PCB's) are here, and they will help connect the electrical components of the circuit. Part of the "Circuit Playground" series.
Find out the scoop on streamgages. What are they? How do they impact everyday life? Whether drinking from the tap, using electricity, or canoeing down a river, all of these activities benefit from information gathered by USGS streamgages.
Part of a series that features a wide variety of video footage, photographs, diagrams and colorful, animated graphics and labels. For this particular video, students will focus on how wind turbines convert kinetic energy from the wind into mechanical and electrical energy. Part of the Science Video Vocab series.
The Solar Decathlon is an annual event where collegiate teams design, build, and operate solar-powered homes. In 2011, it was held on the Mall in Washington D.C. Twenty solar-powered homes were sprawled across the mall’s west end, transforming it from a park into something that resembled a quirky housing development.
Describes how the sound and pictures from a live event get from the camera to the home television screen. Provides a history of television, explaining the switch from black and white to color. Notes the advantages of digital signals over analog. Considers the future of television. Looks at a new technique, digital video compression, in which television signals are received through phone lines.
Mary Elizabeth Wusk started her work at NASA as a summer intern. She began working in aircraft instrumentation and continued developing her career by conducting research on aircraft. With her background in physics and electrical engineering, she has supported and led teams that delivered ground and flight hardware systems. Mary Beth now uses her technology development background in NASA’s Game Changing Development Program Office. Part of the "Women@NASA" series.
Play with voltage and resistance sliders and observe changes to the equation and circuit.
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.
Part of the "A 3-D Demonstration" series. Presents both the theory of electric circuits and basic practical methods of managing circuits safely. Investigates the benefits and dangers of ground circuits together with safety devices, such as fuses and ground fault interrupters. Introduces the concept of electric resistance. Specific modules include Completing a Circuit, Fuses, Circuit Breakers, Ground Circuits, Ground Faults, Ground Fault Interrupters, Resistance, and Electrical Resistance. Correlates to all National CTE Organizational Standards (including the provisions of the Perkins Act).
Carnegie Mellon University Computer Scientist and Electrical Engineer, Anthony Rowe, can always keep an eye on his home, even when he’s traveled to another time zone. That’s because he’s rigged his home with sensors he invented with support from the National Science Foundation. Now all he needs is a laptop to help him keep track of all his appliances – whether they are on or off and how much energy they’re using.
This creature was found 4,200 feet deep in the ocean. It’s called a chimaera, and this fish has no bones in its body. Its skeleton is made of cartilage. The dots on its face are sensory organs that detect electrical fields in the water, which help the chimaera find its prey. Living in deep water, the chimaera is accustomed to lurking in the dark. Part of the "Creatures of the Deep" series.
Engineers are joining forces with designers, scientists, and doctors at Drexel University to produce new biomedical textiles, and the resulting smart clothes are not only fashionably functional, but could also be life savers. With support from the National Science Foundation (NSF), electrical and computer engineer Kapil Dandekar, industrial and fashion designer Genevieve Dion, and OB-GYN Owen Montgomery are incorporating RFID technology into their “belly bands” for women with high-risk pregnancies. The band continuously tracks data and alerts the doctor’s office via the Internet should the woman start contractions. Part of the National Science Foundation Series “Science Nation.”
It bursts from the sun with the power of ten thousand nuclear weapons... and when it hits our planet, it could create the largest disaster in recorded history. A magnetic storm from the sun could wipe out electrical power, television, radio, military communication, and nearly every piece of electronics in the Northern Hemisphere. Learn about a planet-wide "hurricane" of magnetic forces called "Solar Katrina" that could permanently scramble all 21st Century technology. What causes this magnetic superstorm and why is it so powerful? And is there anything we can do to prevent the Magnetic Storm?
Iridium is a rare element used to light up cell phones and TVs. However, researchers have found a way to use a more common element to power electrical devices: copper. Researchers are also developing a better treatment for osteoarthritis through nanotechnology. Other segments include research into specialized metabolites and devices that translate sign language. Part of the "4 Awesome Discoveries You Probably Didn't Hear About This Week" series.
