Technologies to harness solar power as a path to low-carbon energy are developing at breakneck speed. This Spotlight looks at how developing countries can best make use of them to benefit the millions of rural poor who still live without electricity?"

"The gigantic dimensions of this ultra-lightweight revolutionary airplane - capable of flying day and night without fuel - are its trademark feature. To build it, the whole team had to push back the frontiers of knowledge in materials science, energy management and the man-machine interface. Every one of its take-offs, propelled silently by its four electric motors, inspires us to consider using clean, new technologies to free our society, little by little, from dependence on fossil energy. "

"New materials have been among the greatest achievements of every age and they have been central to the growth, prosperity, security, and quality of life of humans since the beginning of history. It is always new materials that open the door to new technologies, whether they are in civil, chemical, construction, nuclear, aeronautical, agricultural, mechanical, biomedical or electrical engineering."

"But as energy demand climbs, so have efforts to turn wind into a viable option for producing electricity on a large scale. Wind turbines in particular are what people think of when discussing wind power. These turbines can measure more than 400 feet (122 meters) tall and weigh in at close to 400 tons."

"Engineering offers more career options than any other discipline. It's a profession that can take you from the depths of the ocean to the far reaches of outer space, from within the microscopic structures of the human cell to the top of the tallest skyscrapers. Whether it's cell phones, digital cameras, DVD's, or facial recognition devices that can pick out a terrorist in a crowded football stadium, engineers are behind almost all of today's exciting technology. Engineers are problem solvers who search for quicker, better, and less expensive ways to use the forces and materials of nature to meet today's challenges. Engineering students have their pick of many fields. From electrical to civil to aeronautical to biomedical, every discipline within engineering will lead to an exciting and rewarding career. In this activity, you will research one type of engineering"

"On April 13, 1970, disaster strikes 200,000 miles from Earth when oxygen tank No. 2 blows up on Apollo 13, the third manned lunar landing mission. Astronauts James A. Lovell, John L. Swigert, and Fred W. Haise had left Earth two days before for the Fra Mauro highlands of the moon but were forced to turn their attention to simply making it home alive. Mission commander Lovell reported to mission control on Earth: "Houston, we've had a problem here," and it was discovered that the normal supply of oxygen, electricity, light, and water had been disrupted. "

"En route to the Moon, approximately 200,000 miles (320,000 km) from Earth, Mission Control asked Swigert to turn on the hydrogen and oxygen tank stirring fans, which were designed to destratify the cryogenic contents and increase the accuracy of their quantity readings. Approximately 93 seconds later, just under 56 hours since launch, the astronauts heard a "loud bang", accompanied by fluctuations in electrical power and firing of the attitude control thrusters.[6] The crew initially thought that a meteoroid might have struck the Lunar Module (LM)."

"The following is a collection of almost 200 single concept lessons. These lessons may be freely copied and used in a classroom but they remain the copyright property of the author(s) and the directors of the SMILE program. The Physics lessons are divided into the following categories: Matter, Mechanics, Fluids, Electricity & Magnetism, Waves, Sound and Optics, and Miscellaneous. "

"Neurons-the electrically excitable cells that make up the brain and nervous system-first fascinated me in high school. In college, like so many other students studying the brain, I dutifully memorized the structure of the archetypal neuron. I also remember learning about a few different types of neurons with different shapes and functions: motor neurons that make muscles twitch, for example, and unique sensory neurons in the eyes and nose."

"developing wireless power delivery systems using laser beams to transmit electricity without wires, for applications where wires are either cost prohibitive or physically impractical."

"popular engineering classes free of charge to students and educators around the world. Stanford Engineering Everywhere (SEE) expands the Stanford experience to students and educators online. A computer and an Internet connection are all you need. View lecture videos, access reading lists and other course handouts, take quizzes and tests, and communicate with other SEE students, all at your convenience. SEE programming includes one of Stanford's most popular sequences: the three-course Introduction to Computer Science taken by the majority of Stanford's undergraduates and seven more advanced courses in artificial intelligence and electrical engineering."

"World's first manned flight with an electric multicopter. At the end of October 2011, Thomas Senkel of e-volo had completed a series of unmanned tests and was ready for the first manned flight on an airstrip in the southwest of Germany. The flight lasted one minute and 30 seconds, after which the constructor and test pilot stated: "The flight characteristics are good natured. Without any steering input it would just hover there on the spot". "

Researchers have found a way to make multiple high-performance anodes from a single silicon wafer. The process uses simple silicon to replace graphite as an element in rechargeable lithium-ion batteries, laying the groundwork for longer-lasting, more powerful batteries for such applications as commercial electronics and electric vehicles.

The Vibro-Wind Research Group, led by Frank Moon, the Joseph Ford Professor of Mechanical and Aerospace Engineering, is working on an efficient, low-cost method of converting vibrations from wind energy to electricity. Much the way solar panels now grace many rooftops, the researchers envision buildings outfitted with vibro-wind panels, which would store the energy they convert from even the gentlest of breezes.

"Energy is the ability to do work. It is one of the basic human needs and is an essential component in any development programme. In this lesson, we are going to look at the forms that energy exists, namely: heat, light, sound, electrical, chemical, nuclear and mechanical. These forms of energy may be transformed from one form to the other, usually with losses. "

"Burt Rutan took the lid off his latest project, the BiPod, at a homebuilders chat this morning, and it looks different than images released last week by Scaled Composites, Burt's former company that owns the design. The first images of the BiPod included CAD drawings with four propellers-one on each wing and two on the horizontal stabilizer between the tails of the twin-fuselage, hybrid-electric roadable aircraft."

"10 Teams Officially Registered for 2011 CAFE Green Flight Challenge The CAFE Foundation has completed Design Review and registration for 10 teams to compete in the 2011 flight competition. These teams include one major university and are from states all across the USA. Their sizes vary widely, as can be seen in the table below. As hoped, teams will campaign with a wide range of energy sources; mogas, diesel, bio-diesel, hydrogen and electricity. The qualifications of the team leaders and members are very impressive."
