Surprisingly, there is a better --not well known-- energy efficient lighting solution than LED for roads, factories, and the like. Interestingly, Tesla invented it! It's called induction lighting. From the latest issue of Distributed Energy magazine... "While it’s more expensive than traditional lighting, it is cheaper than LED. However, it has other benefits, such as long life, due to electrode-less technology. Because there are no parts inside the lamp, it lasts “forever,” which Shelton equates to 100,000 hours or roughly 20 years if left on around the clock. LED is an adequate source light, Shelton explains, but it dissipates quickly—induction...

Exposure to the light of white LED bulbs, it turns out, suppresses melatonin 5 times more than exposure to the light of High Pressure Sodium bulbs that give off an orange-yellow light. "Just as there are regulations and standards for 'classic' pollutants, there should also be regulations and rules for the pollution stemming from artificial light at night," says Prof. Abraham Haim of the University of Haifa. "White" light bulbs that emit light at shorter wavelengths are greater suppressors of the body's production of melatonin than bulbs emitting orange-yellow light, a new international study has revealed. Melatonin is a compound...

One has to ask the question about Greens, do they even live on this planet they are trying to save? They often seem to be living in a completely different universe if not just a different planet. The most recent example of this is the LED light bulb, the latest answer to Congress’s 2007 energy efficiency mandate – which was regrettably signed by George Bush. Last week a story emerged that the 100 watt LED light bulbs slated to replace 100 year old inefficient incandescent bulbs will cost upwards of $50 apiece! That’s right, $50 for a light bulb… Fifty...

NEW YORK – Two leading makers of lighting products are showcasing LED bulbs that are bright enough to replace energy-guzzling 100-watt light bulbs set to disappear from stores in January. Their demonstrations at the LightFair trade show in Philadelphia this week mean that brighter LED bulbs will likely go on sale next year, but after a government ban takes effect. The new bulbs will also be expensive — about $50 each — so the development may not prevent consumers from hoarding traditional bulbs.

A lighting expert who has overseen lighting projects including the Statue of Liberty and the Petronas Towers expressed concerns on Capitol Hill Thursday about the safety of certain types of new light bulbs. Appearing before the Senate Energy and Natural Resources Committee, Howard M. Brandston spoke in favor of the "Better Use of Light Bulbs Act" – a measure which would overturn elements of a 2007 law mandating that traditional incandescent light bulbs be phased out over the next few years. In his testimony, Brandston claimed that parts of the 2007 Energy Independence and Security Act serve as a “de-facto...

What do jet engines and LED light bulbs have in common? They both can overheat without proper cooling mechanisms. But while jet engines are highly effective at staying cool, LED technology is still in its infancy. So GE decided to stick jet engine cooling mechanisms inside LED bulbs. The result: a lightweight 1,500 lumen LED bulb that produces as much light as a 100 watt halogen bulb while using a third of the energy. The key to GE's new bulb is microfluidics technology. GE explains:GE dual cool jets are very small micro-fluidic bellows-type devices that provide high-velocity jets of air,...

Here’s a warning you can give to your company’s drivers: Beware snow-covered traffic signals. They’re a new problem due to energy-efficiency efforts. Many traffic lights now use LED bulbs instead of incandescent ones. Reason: The LEDs are 80% to 90% more energy-efficient. And that energy efficiency is the problem. The energy wasted by incandescent bulbs was heat. But in winter storms, that heat was melting snow that accumulated on the lights. The LEDs don’t generate enough heat to melt snow, and that’s been blamed for one traffic fatality and dozens of other collisions and injuries. In a storm in Illinois...

Mousavi Accuses Obama of 'Misleading the World' Sunday, June 21, 2009 1:38 PM Author and foreign policy expert Michael Ledeen has published a letter reportedly from the office of Mir Hossein Mousavi, in which the Iranian opposition leader criticizes President Barack Obama for saying Mousavi and Iranian President Mahmoud Ahmadenijad are "two of a kind." The letter, addressed to Obama, takes the president to task for the remark, calling it "a grave and deep insult, not just to Mr. Mousavi but especially against the judgment of the Iranian people, against our moral conviction and intelligence, especially those of the young...

Walk around the floor of Lightfair International, the lighting industry’s annual trade show at the Javits Center in New York last week, and you would be forgiven for thinking that lamps based on light-emitting diodes, or LEDs, had already filled our homes and workplaces. LED bulbs and fixtures dominated nearly every booth on the show floor. Now all the world has to do is catch up. Most people think of LEDs as the lights blinking from inside electronic devices. They are being used increasingly to light rooms, though few people have ever bought them. “In the U.S., 78 percent of...

February 2, 2009 Cambridge University researchers have developed cheap, light-emitting diode (LED) bulbs that produce brilliant light but use very little electricity. They will cost just GBP2 (USD2.80) and last up to 60 years. The gallium nitride based bulbs are 12 times more efficient than conventional tungsten incandescent bulbs and three times more efficient than compact fluorescent low-energy bulbs. As well as lasting 100,000 hours, ten times as long as today's eco-bulbs, the LED bulbs do not contain mercury, so disposal is less damaging to the environment, they do not flicker and fully illuminate instantly, unlike the current generation of...

Winchester, UK - Cambridge University's Centre for Gallium Nitride has developed a new way of making GaN which could produce LEDs for a tenth of current prices and may see household lighting bills reduced by up to 75 percent within five years. [snip] Currently GaN LEDs can only be grown on 2-inch sapphire wafers. Following the Cambridge innovation nine times as many LEDs can be grown on a 6-inch silicon wafer compared with a 2-inch sapphire wafer. In addition, edge effects are less, so the number of good LEDs is about 10 times higher. The processing costs for a 2-inch...

A "revolution" in the way we illuminate our world is imminent, according to a paper published this week by two professors at Rensselaer Polytechnic Institute. Innovations in photonics and solid state lighting will lead to trillions of dollars in cost savings, along with a massive reduction in the amount of energy required to light homes and businesses around the globe, the researchers forecast. snip If all of the world's light bulbs were replaced with LEDs for a period of 10 years, Schubert and Kim estimate the following benefits would be realized: Total energy consumption would be reduced by 1,929.84 joules...

Standards Set For Energy-conserving LED LightingThese solid-state lights are powered by energy-efficient light emitting diodes and are among the first ones of a new generation expected to cut energy needed for lighting by 50 percent by 2027. (Credit: NIST) ScienceDaily (July 1, 2008) — Scientists at the National Institute of Standards and Technology (NIST), in cooperation with national standards organizations, have taken the lead in developing the first two standards for solid-state lighting in the United States. This new generation lighting technology uses light-emitting diodes (LEDs) instead of incandescent filaments or fluorescent tubes to produce illumination that cuts energy consumption...

Brighter LED Lights Could Replace Household Light Bulbs Within Three Years ScienceDaily (Jan. 10, 2008) — Researchers are developing new technology that could replace the household light-bulb within three years. Light Emitting Diodes (LEDs), already used in electrical equipment such as computers and mobile phones, are several times more energy efficient than standard light-bulbs. However, because of their structure and material, much of the light in standard LEDs becomes trapped, reducing the brightness of the light and making them unsuitable as the main lighting source in the home. Now researchers believe they have found a way of introducing a new...

The group’s best-of album, Mothership, have already gone Platinum, meaning it has sold more than 300,000 copies, but Gennaro Castaldo, a spokesman for HMV, said it was on track to become one of the biggest best-sellers. Robert Plant and Jimmy Page perform in Istanbul in March Sales of the album at the company’s 240 stores leapfrogged those of Westlife and the Spice Girls to become the chain’s number one seller. “Sales...

Led Zeppelin to get heavy on ticket touts By Joanna Corrigan Last Updated: 2:14am GMT 10/12/2007 Led Zeppelin fans who bought tickets online for the band's first performance in almost 20 years could be turned away from the concert because of stringent security measures. Touts have been selling tickets to the band's reunion on auction websites such as eBay despite organisers trying to prevent anyone apart from winners of the official ballot from attending the show at London's O2 arena. Only fans with a special code obtained in the ballot, photographic ID and the credit card that paid for the...

It appears that Page, Plant and Jones are planning a reunion with Bonham's son, Jason, on drums.

LEDs Expand Their Reach Into the Aesthetic-Minded Market for Home Lighting EVERETT, Mass. (AP) -- Joey Nicotera's fascination with multicolored light bulbs bordered on obsession when he was a teenager. He framed posters in lights and decorated his own Christmas tree. When he couldn't find a color bulb he wanted, he got paint cans from the basement and made some himself, bathing his second-story bedroom in an eerie glow. "I'd be driving home from work at night, and I could see his room from five blocks away, with all the weird colors and flashing lights," recalls his father, Joe Nicotera...

June 22, 2007 With over half a billion fluorescent light globes disposed of each year in the U.S. alone, there is no doubting the significance of a product that allows existing fluorescent fixtures to be converted to Light Emitting Diodes (LEDs) by simply changing the bulb. The world's first true replacement of glass fluorescent lighting tubes, the EverLED TR from LEDdynamics utilizes the existing fluorescent ballast, while achieving the equivalent light output of the tube it replaces. In addition to energy savings, the benefits of LED lighting technology include a 10 year service life, high quality light, and cold temperature...

WASHINGTON – As state and foreign governments enact forced phase-outs of incandescent light bulbs, consumers are being kept in the dark about the many downsides of compact fluorescent lamps replacements being billed as an environmental and energy-savings panacea. Across the U.S., schoolchildren are being urged to replace incandescent light bulbs in their homes, state legislatures are following the leads of foreign governments in banning the sale of the bulbs in the future and the federal Department of Energy and Environmental Protection Agency are highly recommending the switch to CFLs. Businesses like Wal-Mart are also pushing CFLs hard, as are environmental...

SAN JOSE, Calif.--Light-emitting diodes will become economically attractive as replacements for conventional lightbulbs in about two years, a shift that could pave the way for massive electricity conservation, according to a researcher. Right now, consumers and businesses can buy a light-emitting diode, or LED, that provides about the same level of illumination as an energy-hogging conventional 60-watt lightbulb, Steven DenBaars, a professor of material science at the University of California Santa Barbara, said at the SEMI NanoForum, taking place here this week. A principal advantage of the LED: It lasts about 100,000 hours, far longer than the conventional filament bulb...

Agent who led Bin Laden hunt criticises CIA Suzanne Goldenberg in Washington Saturday July 8, 2006 The Guardian (UK) The man who led America's hunt for Osama bin Laden has said the CIA was wrong to disband the only unit devoted entirely to the terrorist leader's pursuit - just at a time when al-Qaida is reasserting its influence over global jihad. Shutting down the Bin Laden unit squandered 10 years of expertise in the war on terror, said Michael Scheuer, who founded the unit in 1995 and arguably knows more about Bin Laden than any other western intelligence official. He...

TUCKER, Ga. (AP) -- A strange chain of events that began with a traffic accident and a gas leak ended this week with the discovery of nearly $900,000 worth of marijuana growing in a suburban apartment. It began when a drunken driver crashed into an apartment building Sunday morning, said Officer Darren Moloney, spokesman for the Gwinnett County Police Department. The collision ruptured a gas line, prompting firefighters to respond to check for leaks. While checking inside one of the units, they found an indoor pot growing operation, Moloney said.

When scientists developed an efficient device for emitting light, they hadn't realised butterflies have been using the same method for 30 million years. Fluorescent patches on the wings of African swallowtail butterflies work in a very similar way to high emission light emitting diodes (LEDs). These high emission LEDs are an efficient variation on the diodes used in electronic equipment and displays. The University of Exeter, UK, research appears in the journal Science. In 2001, Alexei Erchak and colleagues at the Massachusetts Institute of Technology (MIT) demonstrated a method for building a more efficient LED. Most light emitted from standard...

Within two years they were dead, shot in their...

NEW YORK (AP) - If a time traveler from a hundred years ago were to visit a home today, much of the technology would be completely alien. The television, cordless phone and computer would probably leave him flabbergasted. But on seeing a light bulb, he might say, "Ah! Here's something I recognize. A few of those grace my home, too." If the visitor comes back in 15 years, the fruit of Thomas Edison's bright idea may be gone. The likely replacement: light-emitting diodes, or LEDs. LED lamps were unthinkable until the technology cleared a major hurdle just a dozen years...
