"Ever wonder how much energy is used by your different major appliances or electronics? Or how much energy all such appliances and electronics in the U.S. use? Here's some info on that for four big ones: TVs, computers, clothes dryers, and refrigerators."

"Clifford Bedford, a researcher involved in the development of the new material, explained its advantages over existing weapons. "In the case of a steel missile you explosively launch it, it goes through the target and all the kinetic energy is dissipated into the target," he said. "With the reactive material missile, you have the same explosive launch - however, it disintegrates within the target and liberates chemical energy, and this chemical and kinetic energy combined gives you the enhanced effect.""

"First results from a major astronomical survey using a cutting-edge technique appear to have confirmed the existence of mysterious dark energy."

The TB4000 is a new system that may solve mankind's reliance on fossil fuels, and usher in a golden age of world peace and prosperity.

"Many might be alarmed to learn of a homemade nuclear reactor being built next door. But what if this form of extreme DIY could help solve the world's energy crisis? "

Arithmetic, Population and Energy, a presentation by professor Albert A Bartlett

"An ambitious solar energy project on a massive scale is about to get underway in the Arizona desert. EnviroMission is undergoing land acquisition and site-specific engineering to build its first full-scale solar tower - and when we say full-scale, we mean it! The mammoth 800-plus meter (2625 ft) tall tower will instantly become one of the world's tallest buildings. Its 200-megawatt power generation capacity will reliably feed the grid with enough power for 150,000 US homes, and once it's built, it can be expected to more or less sit there producing clean, renewable power with virtually no maintenance until it's more than 80 years old."

"Claims that the costs of wind farms and other low-carbon technology will lead to sharp rises in fuel bills are wrong, government advisers say. The Committee on Climate Change (CCC) says increases in bills over the past few years have been largely due to higher wholesale gas costs."

"Building scientists have known for a long time that glass-walled structures are less energy efficient than the stone and concrete buildings that were put up forty of fifty years ago. But the market demand for glass combined with the relatively low cost of glass-wall construction means the building industry has been happy to oblige."

Throw-away Buildings Thermal Window Failure: How it Happens Virtually all glass condominium towers feature window wall systems (floor-to-ceiling walls of glass) enclosing the entire facade. Window walls yield spectacular views, but owners who buy a condo unit for the view may not realize that they're relying on a couple of panes of glass separated by less than an inch of insulated space to protect them from the elements. That insulated barrier will degrade over time, even as energy costs increase. On some buildings, five per cent of the thermal windows may have failed before they're even delivered to the construction site. Another 10 - 15 per cent will fail by the 20-year mark as they're exposed to the physics of heat expansion. By the 25 year-mark, a growing number will fail every year.

"Now a different team at the same lab reports findings that, they say, cast doubt on that surprising result. The Icarus team at the Icarus experiment says that because the neutrinos sent from Cern do not appear to lose energy on their journey, they must not have exceeded the speed of light along the way."

Join Bill Nye as he delves into the Greatest Discoveries in Biology. This program explains how the early use of microscopes and Anton Van Leeuwenhock's accidental discovery set the stage for studying microorganisms. It explores 19th century research breakthroughs and covers cell division, sex cell division, and cell differentiation. Learn how the discovery of mitochondria has helped us understand reproduction, ancestral lines, and cancer; how cells convert sugars, fats, and proteins into energy in the Krebs Cycle; and how they communicate through neurotransmitters and hormones. Explore the process of photosynthesis and how the discovery of the ecosystem process bridged biology with physics, chemistry, and other fields of science that describe the environment.

Bill Nye and the Discovery Channel give you the greatest discoveries in physics. Nye explores how the universe operates and why things move and work the way they do. He also explains the second law of thermodynamics, electromagnetism, and how superconductors can help accelerate particles to near the speed of light. He illustrates Albert Einstein's theory that clocks tick slower at the speed of light and even on an airplane, and discusses how E=MC2 helped develop nuclear power, the quantum leap, the power of electromagnetic energy, the structure of an atom, and the subatomic particles known as quarks.

Shawn Frayne talks about his new method of transforming wind power into electric energy. http://www.humdingerwind.com

"The engineer at Embry-Riddle Aeronautical University in the US is currently finalising designs for a series of turbines that could be used to harness the immense energy of the Gulf Stream, flowing deep in the Atlantic Ocean."

"The upper layer of the world's ocean has warmed since 1993, indicating a strong climate change signal, according to a new study. The energy stored is enough to power nearly 500 100-watt light bulbs per each of the roughly 6.7 billion people on the planet."

Plugging gadgets into a socket in the wall, or loading them with batteries - or maybe even unfurling a solar panel - is how most of us think of getting electricity. But what about plugging them into your body?
